Lockheed Martin’s Joe Landon on the emerging space economy
By Chris Daehnick
We may be approaching an age in which companies conduct business in orbit or on the moon, says Lockheed Martin executive Joe Landon.
https://www.mckinsey.com/industries...tins-joe-landon-on-the-emerging-space-economy
Joe Landon envisions a new economy developing in space—one that closely mirrors the economy on Earth and requires the same skills. “What the space industry needs is more business talent and more people who understand how to build businesses,” he says. As vice president of advanced programs development for Lockheed Martin Space, Landon leads teams that focus on new-business growth, strategy, and R&D for human spaceflight, robotic deep-space exploration, and other space-related activities. He is filling this role at an exciting time for the company, which was recently awarded a NASA contract to develop a first-of-its-kind commercial space station that will facilitate research, plant growth, and astronaut activity in space.

“My job is to predict the future,” Landon says, “and the hardest part is figuring out how to position our company in an increasingly competitive market.” He recently met with McKinsey’s Chris Daehnick to discuss the future of space. The following are edited excerpts of their conversation.

The ‘space for space’ economy

Joe Landon biography: launching satellites that look down on Earth, or that help us communicate from one place to another on Earth. Those are space-for-Earth services. Now, we’re going to start seeing more value being created and exchanged in space, for space.

For example, you could have a spacecraft that gets refueled in space. That’s a transaction or activity that doesn’t have an anchor on Earth. It’s happening between two companies or two spacecraft, either in orbit or maybe on the moon.

Also in the future, I see a world where getting things into space is essentially free of charge. The only thing that will cost money is sending people into space because people can’t be printed or produced in space. The other things we need in space will be produced there, using resources also found in space. We’ll be able to find building materials and everything else we need there. I think there could be a major disruption in the industry because of additive manufacturing and 3-D printing.


Joe Landon: I’m a little bit biased, but I think it’s NASA’s Artemis Program, which focuses on exploring the moon and sending humans back there. Lockheed Martin is the primary contractor building the Orion spacecraft for this program. There’s tremendous scientific benefit to Earth from the Artemis exploration. NASA and the space industry are laying the foundation to build infrastructure in space and around the moon.

Chris Daehnick: Do you think that there is a near-term possibility for some of the more expansive space ideas, such as human settlements on Mars or orbital space cities?

Joe Landon: I’m optimistic that we will continue to explore and go further. We’ll need to figure out what activity will create value, whether that’s scientific value or economic value or other opportunities. If we can build more self-sustaining operations and settlements in space, that can be a source of value. But I think it’s going to take a lot longer for humans to get to Mars than most people expect. It’s not that we won’t try; we are actually investing quite a bit to make the systems needed. There has also been extensive exploration beyond the moon, and even beyond Mars, using robotic spacecraft.

But the technical challenges are significant. Getting humans beyond Mars is a real challenge because it’s very far. You start having trouble generating power and communicating. There are some technologies that we’re developing that can help, and if we can build upon these technologies, I think it will be possible to explore the outer solar system.

Chris Daehnick: Space is a rather unforgiving environment. What are some of the challenges that we have to overcome to enable humans to spend a long time there?

Joe Landon: We need to develop the technology to support a long-term presence in space and long-duration space flights. We also need the consumables required to support life for long periods. We’re working on and investing in the propulsion technology required to make trips in space faster. The shorter the trip is, the easier it is to keep the crew comfortable. We’re also working on artificial-intelligence systems to help crews manage their time in space and work alongside their spacecraft with limited help from Earth. We want to provide a safe journey for those astronauts.

Sustaining human life in space
As you get farther away from Earth, you can’t rely on Earth for help. So we need to anticipate and be able to take care of problems in deep space.

Chris Daehnick: Is there any ongoing research to understand how people deal with long-term confinement in a restricted environment?

Joe Landon: Sure, there are a number of programs called space analogs—there’s the Mars Desert Research Station, in Utah, and a facility in Hawaii called HI-SEAS—where we send crews into confined environments that simulate being on Mars or being on a long-duration space flight.

The role of private companies and government agencies
Chris Daehnick: Let’s talk about funding. Governments have traditionally funded space ventures, but many private companies are becoming involved in space tourism and other activities. How do you see the role of private companies and the government evolving?

Joe Landon: A lot of private investment is now going into launch vehicles and launch availability. Both government and private industry have benefited greatly from that because it reduces costs and increases the ability to get stuff into space more reliably and more often. A lot of private investment is also going to communications and Earth observation. Having those types of services expand and become more readily available will help everyone. For instance, we might soon have ubiquitous internet connectivity.

For science and space exploration, the government is still going to be the major customer. But government agencies, NASA in particular, are going to make purchases and do business in a more commercial way. We have to adapt to an environment in which NASA will be buying services and expecting companies to develop new product offerings or new businesses. Once a company like ours develops a service for NASA, we can then offer it to other customers, including commercial companies, government agencies, and other national space agencies.

Think about a scientific mission to study the moon. NASA or another agency would not need its own communications link, power, or transportation; it could instead buy those as a service. In fact, NASA has already started to do this for the transport of payloads to the moon. Companies that provide that service for NASA could do the same thing for other customers. This would expand the market and bring in new opportunities.

Chris Daehnick: What does that mean for space companies? Do they need to change the way they do business?

Joe Landon: We have to stop thinking about ourselves as space companies and start thinking about the actual services that we’re providing. Space is a place, and we need all kinds of businesses there. We need to think about building a diverse and robust industrial sector in space. Now is the time to start partnering with the leading companies that provide those types of services on Earth and bring the best that we have into space. For example, Lockheed Martin and General Motors are working together to build the next generation of lunar rovers. We’ve taken the best of Earth transportation to adapt for space.

The talent we’ll need in space
Big, established companies like Lockheed Martin have to act more like start-ups these days. There’s more collaboration between start-ups and established companies now, but also more competition. Overall, I think that’s good for the industry.

Chris Daehnick: What would you say to a young person today who is thinking about pursuing a career in space? What should they study?

Joe Landon: We need all kinds of talent in space. Of course, engineers and scientists are needed, but that’s just the beginning. Space is just a place—it’s a place where you can do business—so we’ll need doctors, lawyers, and everything you can imagine in space.

We’ll need more people who understand how to build businesses. To build this commercial space economy that we aspire to, we’ll need entrepreneurs and people who understand finance, marketing, accounting, and all these fields that aren’t typically associated with space but have always been a part of the space sector. Those fields will grow in importance going forward.

Space balloon company offers first look at luxury cabins
https://phys.org/news/2022-04-space-balloon-company-luxury-cabins.html
this-image-rendering-h.jpg

This image rendering handout courtesy of Space Perspective released April 7, 2022 shows the exterior of the spaceship Neptune capsule floating above Florida.
A new entrant in the space tourism market promises customers views of the Earth's curvature from the comfort of a luxury cabin, lifted to the upper atmosphere with a giant balloon.

Space Perspective on Tuesday revealed illustrations of its swish cabins, which it hopes to start launching from the Kennedy Space Center in Florida from late 2024. More than 600 tickets have so far been sold, at $125,000 each.

With five-feet (1.5 meter) high windows, deep seats, dark, purple tones and subdued lighting, the atmosphere contrasts with the white and sanitized capsules of its competitors.

Wifi connectivity and a drinks bar round out the "Space Lounge" inside the company's Neptune capsule.

Whether it really constitutes spaceflight is a matter of debate.

The balloon reaches an altitude of 20 miles (30 kilometers), much lower than rivals Virgin Galactic, which goes just over 50 miles high, or Blue Origin, which breaches the Karman Line, 62 miles above sea level, the internationally-recognized space border.

SpaceX Crew Dragons fly even deeper into space.

But 20 miles is still far higher than commercial planes, which ascend around six miles high.

"We are above 99 percent of Earth's atmosphere," co-founder Jayne Poynter told AFP, meaning passengers will really see the inky black of space.

with-five-feet-15-mete.jpg

With five-feet (1.5 meter) high windows, deep seats, dark, purple tones and subdued lighting, the atmosphere contrasts with the white and sanitized capsules of its competitors.
There's no special training required. The balloon climbs at a serene 12 miles per hour (19 kilometers per hour), and the company pitches itself as a greener, zero-emissions alternative to rocket fuels.

They intend to get the hydrogen for the balloon from renewable sources, rather than extracting it from fossil fuels.

The price for the two-hour-up, two-hours-gliding, and two-hour-down voyage, which ends with an ocean splashdown, is significantly less than Virgin Galactic tickets that cost $450,000 for a ride on a spaceplane.

Blue Origin doesn't disclose its prices but they are thought to be far more, while four entrepreneurs who flew to the International Space Station on a SpaceX ship paid a reported $55 million each to the company Axiom Space for the privilege.

"We wanted to find a way that really changed the way people think about spaceflight that makes it much more approachable and accessible," said Poynter.

One thing the passengers won't experience is feelings of weightlessness.

With Virgin's spaceplane and Blue Origin's rocket, passengers can unbuckle and float when the rocket engines are cut but the ship keeps coasting upwards for a few minutes, before gravity pulls it back down.

Passengers on SpaceX spaceships and those on the ISS likewise experience apparent weightlessness because the vessels are orbiting the Earth.

Space Perspective plans 25 flights in its first year, with all seats now booked.

Spacesuits are showing their age

Astronauts’ wardrobes are in need of a makeover
Apr 23rd 2022

https://www.economist.com/science-and-technology/spacesuits-are-showing-their-age/21808842
Cbu6PLB.jpg

Fixing panels on the International Space Station (iss) is a bit like doing car repairs while wearing stiff oven gloves and standing on a skateboard. That, at least, is the way Kate Rubins, an astronaut at nasa, America’s space agency, describes it. And she has spent 300 days orbiting Earth on board the station, so she should know.

Today’s bulky spacesuits weigh (or, for pedants, have a mass that is) nearly a third more than those sported by the Apollo astronauts who walked on the Moon in the 1960s and 1970s. To complicate matters further, the free fall of orbit lacks the dampening effects on Newton’s first and third laws of motion (things move for ever unless acted on by a force, and every action results in an equal and opposite reaction) which are offered by the Moon’s gravitational field and solid surface. Spacewalkers must therefore think far more carefully about the consequences of their actions than Moonwalkers need to.

Add in the fact that most systems in spacesuits used today were designed in the early 1980s, giving plenty of time for their flaws to become apparent (in 2013, for example, an Italian astronaut on the issnearly drowned when more than a litre of cooling water pooled inside his helmet). Add further that nasa hopes to return astronauts to the Moon at some point in the 2020s and it is clear the time has come for an upgrade. nasa has a long list of features it would like to modify or add. But Chris Hansen, head of extravehicular activity at the agency, says the immediate objective is to develop suits that permit far more body movement than the rigid ones which, as he puts it, had Apollo Moonwalkers “hopping around like bunnies and falling over”.

Tailoring away
nasa’s quest for new suit designs has not, however, gone well. In August 2021 Paul Martin, its inspector-general, concluded that 14 years and $420m had been spent for meagre results. Mr Martin also said that despite nasa’s intention to double that sum over the following few years, it would still not produce spacesuits in time for a Moon landing that was then planned for 2024 (and now delayed to 2025). So, learning yet again a lesson that it really ought to have taken on board by now, the agency is farming out suit design to the private sector. The idea is to come up with something that can be adapted for use both in orbit and on the lunar surface. The winner will be announced next month.

As Dr Hansen’s remarks foreshadow, an important criterion of success in this competition will be a spacesuit’s flexibility. One contender is Astro, a suit proposed jointly by three firms: Collins Aerospace, of Charlotte, North Carolina; ilc Dover, of Newark, Delaware; and Oceaneering, of Houston, Texas. Astro makes extensive use of Vectran, a synthetic fibre tougher than the Kevlar employed in bulletproof garments. This is made using a liquid-crystal polymer that confers both strength and the necessary flexibility.

Wearers of such a suit should be able to reach up and bend down, gestures that would be impossible in today’s spacesuits. According to Dan Burbank, a former astronaut who helped assemble the iss in orbit and who is now a technologist at Collins, they could even perform press-ups, at least when gravitationally bound to the surface of the Earth.

A version of Astro designed for Moonwalks would allow treks of perhaps 10km, a distance that dwarfs those managed by Apollo astronauts. This lunar hiking kit would be fitted with special boots and a “breadcrumb-trail” display on its face shield to show the occupant where he or she had been—and thus, crucially, how to get back home.

For spacewalks in Earth orbit, however, some people question the need for suits at all. Instead, they propose miniature spacecraft fitted with thrusters and robotic arms. Genesis Engineering Solutions, a firm in Maryland, is going down this route with what it calls the Single-Person Spacecraft (sps). The thrusters use compressed nitrogen—though, in an emergency, they could also tap into the craft’s air tanks. The arms were originally designed for defusing bombs, making them far more dexterous than an astronaut’s gloved hand; they can be controlled either by the spacewalker or by a remote operator. If all goes well the spswill be used on Orbital Reef, a commercial space station being built by firms including Blue Origin and Sierra Space, and scheduled for launch in the late 2020s.

The sps, Genesis believes, offers several advantages over conventional spacesuits. For one thing, no airlock is needed to permit entry to and exit from a space station. Instead, the craft docks directly with the station, so the two share their air until the hatches between them are closed. That means a pilot can shimmy in and out of an sps with little fuss. In contrast, for a suited spacewalker to leave and return to the mothership requires an airlock to be pumped down for exit and then pumped up for re-entry. Given that pumping down is never completely efficient, this inevitably leaks part of a station’s air supply.

Another key difference is that a spacecraft can operate at atmospheric pressure. Pressurising a suit to this extent, however, increases its rigidity, making its gloves in particular so stiff as to be useless for manual tasks. The pressure inside a spacesuit is therefore normally held at about one-third of an atmosphere. But this would not deliver enough oxygen for an astronaut to breathe if standard air were used. So pure oxygen is employed instead.

One consequence of that pressure drop is a risk of decompression sickness, in which nitrogen gas emerges from the bloodstream in painful and dangerous bubbles. So before suiting up spacewalkers must undergo a so-called pre-breathe of pure oxygen to purge the blood of nitrogen. A pure-oxygen atmosphere is also a fire hazard. That is not a theoretical risk. Three Apollo astronauts were killed by fire in a ground test in 1967 because their capsule contained such an atmosphere.

Spacesuits bring a third safety hazard, too, according to Brand Griffin, who leads the sps effort at Genesis. He says that the shielding on an sps provides protection against fast-moving debris and micro meteoroids that would puncture a suit. Were this to happen, the vacuum of space would cause the astronaut’s body fluids to vaporise. And yet another advantage of a spacecraft is that, if a pilot were somehow incapacitated, its thrusters could be remotely controlled and docked with the mothership more easily than a spacewalker could be hauled back into an airlock.

The downside to miniature spacecraft is price. An sps will, according to Genesis, cost nearly $70m—around four times the price of a spacesuit. But lower running costs may compensate for such upfront expenditure. With tasks including adjusting a suit to the astronaut who will wear it (for they are not bespoke items), donning and doffing it, and sterilising its interior after use, a single spacewalk requires about 63 hours of labour on board the iss, not counting the excursion itself. For an inkling of the expense involved in this, consider that the charge-out rate for a nasa astronaut’s services on the iss is $130,000 an hour. Blue Origin, the moving spirit behind Orbital Reef, reckons that, once such costs are factored in, an sps will end up being the cheaper option.

Suited spacewalks are, in any case, so dangerous that nasa is discouraging the operators of planned commercial space stations like Orbital Reef from engaging in them. As for space tourists, extravehicular outings have always been out of the question, no matter how dazzling the experience would be. The sps will change that, says Brent Sherwood, Blue Origin’s head of advanced development programmes. He foresees “tourist-proof”, automated excursions as part of package holidays in space.

Haute couture
Even if it works as intended, though, the sps will not end the need for spacesuits. Gateway, a lunar-orbiting international space station, the assembly of which is planned to start sometime after November 2024, has been designed for outings from it to happen in suits, not single-astronaut spaceships. Orbital Reef will, for its part (and despite nasa’s scepticism), support suited spacewalks as well as the sps. That system, after all, has yet to prove itself.

Moreover, spacesuit technologists have other ideas up their sleeves. ilc Dover, for example, plans to simplify suited spacewalking by delivering life support via an umbilical cord. This would limit mobility but cut costs sharply, says Dan Klopp, head of business development at the firm. “Suitports” are also promising. With these, an astronaut would climb into the back of a spacesuit attached to the outside of a vehicle. After the spacesuit and vehicle had been sealed, the suit could be detached with no airlock required, as with the sps.

Hovering over all of this, it should be acknowledged, is the question of whether spacewalks and Moonwalks by people actually achieve anything that robots (either remotely controlled or fully autonomous) cannot. To ask that, though, is to challenge the whole reason for crewed space flight. And that would never do, would it? ■

The Plan to Make Michigan the Next Space State
Residents are up in arms about a proposed spaceport project, the first of its kind in the Midwest, which would involve launching rockets near the shoreline of Lake Superior.

One of the largest log cabins in the world can be found in the Upper Peninsula of Michigan, on the edge of Lake Superior. The property, called Granot Loma, is twenty-six thousand square feet, and it belongs to Tom Baldwin, a sixty-five-year-old former bond and commodities trader. Baldwin made his fortune in the Treasury-bond pit at the Chicago Board of Trade, where his colleagues referred to him as the King. He was known for trading two billion dollars’ worth of bonds in a single day. Last fall, I drove to see him at Granot Loma, in Powell Township, seventeen miles north of the city of Marquette. He gave me directions over the phone, telling me to turn off the main road and onto County Road KE. “Essentially, it’s my driveway,” he said. He wasn’t exaggerating. I continued down the road for more than a mile until I reached a locked gate, which opened a few seconds after I arrived.

The cabin was built in the early nineteen-twenties by Louis G. Kaufman, a banker and businessman who helped finance the construction of the Empire State Building. He came up with the name Granot Loma by combining letters from the names of his children. Kaufman died in 1942, and more than four decades later Baldwin bought Granot Loma—and the five thousand acres on which it sits—for 4.25 million dollars. “I was looking for a large piece of property that had wilderness for outdoor recreation, and for privacy, as a retreat,” he told me. He embarked upon an extensive restoration, installing a kitchen equipped with appliances similar to those in the White House.

I had come to visit Baldwin because Granot Loma had been selected as the location for a proposed rocket-launch site, as part of a plan called the Michigan Launch Initiative. If built, the site, along with two other facilities, would constitute the first spaceport in the Midwest. The site planned for Granot Loma would host vertical launches, through which rockets carrying satellites and other payloads—not human passengers—would be sent into low-Earth orbit. The second facility is a horizontal-launch site at the Oscoda-Wurtsmith Airport, about two hundred miles north of Detroit, where aircraft carrying satellites would take off from runways. Operations for both sites would be supported by the third facility, a command-and-control center, which would be situated in the Upper Peninsula, in Chippewa County, east of Marquette.

The spaceport plan is the brainchild of the Michigan Aerospace Manufacturers Association (mama), a trade association founded in 2007. mama estimates that the command-and-control center will be operational by 2023, and that all three sites of the spaceport will be up and running by 2026. Their initiative has been polarizing: some locals believe that the spaceport will benefit the economy and attract more talent to the state, while others, particularly those who live close to Granot Loma, worry about the potential disruption of having rocket launches in their back yards. Many are also distressed about the potential environmental risks, given that the rockets for the vertical site would launch near the shoreline and likely fly over Lake Superior.

When I spoke with Baldwin at Granot Loma, we sat in a spacious alcove that resembled the bridge of a vessel poised for voyage. Outside the windows, the waters of the lake stretched gray and frothy to the horizon. “This is the most inhospitable location on Lake Superior,” Baldwin said. “We jut out on the peninsula, and typically we get thirty-mile-per-hour winds from the north or northwest that come right at the lodge, along with the rain and the sleet and the snow.”


Lake Superior is seemingly more ocean than lake. By surface area, it is the largest body of freshwater in the world. If you haven’t seen it up close or from an airplane—and even if you have—it can be difficult to grasp the significance of a lake so immense that it has its own weather systems. Lake Superior could accommodate the combined landmasses of Connecticut, Delaware, Hawaii, and Maryland. Like the Pacific and Atlantic Oceans, it provides a wide-open, uninhabited area for launching rockets.

Baldwin said that he began communicating with mamain 2019. Earlier that year, the organization had received a two-million-dollar, taxpayer-funded grant from the state of Michigan, in order to conduct a series of feasibility studies for a possible spaceport. One of those studies involved vetting several potential launch-site locations throughout the state, and mama hired consultants who scored the sites in categories ranging from “environment” and “safety” to “business.” By the end of the process, the consultants had identified Baldwin’s land as the ideal vertical-launch spot.



Baldwin told me that mama is interested in acquiring half of his five thousand acres. (A spokesperson for mama would confirm only that the group is looking to acquire a “portion” of Baldwin’s land.) The two parties have yet to close a deal. “I could sell it to them for fifty million dollars, but I wouldn’t,” Baldwin said. “I think it’s worth a lot more to them than that. They couldn’t do it without me.” He estimated that the twenty-five hundred acres are worth at least a hundred million dollars to mama.

There are alternatives to selling his land outright. Baldwin could lease it to mama, or, he said, he could keep the land and become the operator of the launch site, although that outcome is unlikely. “I haven’t decided what role I want to play,” he said. “That will determine a lot of the financial aspects.” When I asked if he would be interested in operating the facility, he said, “Yes. I’m an entrepreneur. But my reputation is that I don’t play well with other children.” He went on, “Is it my goal to operate a spaceport? No. I vacillate. You get older. You lose energy. As intriguing as it is to me, I don’t underestimate the amount of energy it would take to do that. I also don’t have the aeronautical education that Elon Musk has. So, if Elon Musk wanted a joint venture, I would do it.” I asked him whether Musk has communicated with anyone involved with the Michigan Launch Initiative. “He’s reached out to us,” Baldwin said, before correcting himself and saying that Musk had contacted mama specifically. (mama said that it has discussed the initiative with representatives from Musk’s company, SpaceX, which did not respond to a request for comment.)

As he showed me around Granot Loma, Baldwin opened a door on the east side of the lodge, and invited me outside so that I could see where mama wants to blast rockets into orbit. An icy wind blew hard off the lake. “Over there,” he said, gesturing to the right of a skinny headland known as Thoneys Point, beyond his mile-long private beach. “About two thousand feet in from the shore.” (mama said the location of the launchpad has not yet been determined.) A few days later, Baldwin e-mailed me what looked like a satellite image of his land; a green dot indicated the approximate location for rocket launches. He asked me not to publicize it. “My main fear is from trespassers and sightseers,” he said.

On July 23, 2020, Gavin Brown, the founder and executive director of mama, announced that Michigan was going to become the next “space state.” Standing on the steps of the Marquette County Courthouse, he unveiled four illustrations for the proposed launch site at Granot Loma, depicting sleek but generic low-lying buildings, surrounded by grassy areas. “You are the vertical site for Michigan,” Brown told the audience. “When people say the great space race is on, they will not only say it’s the entire state of Michigan but come to the U.P.,” he said, using the acronym for the Upper Peninsula, to see where “the technology for space is taking place.” (Brown declined to sit for an interview but answered questions about the Michigan Launch Initiative via e-mail, through a spokesperson.)
There are currently thirteen spaceports in the United States that are licensed by the Federal Aviation Administration (F.A.A.). Although the most well-known location is probably in Florida, at Cape Canaveral, the sites are geographically diverse: there are spaceports in Kodiak Island, Alaska; near the Mojave Desert; and on the outskirts of Truth or Consequences, New Mexico. Some are licensed for horizontal launches only; others exclusively do vertical launches; only one, Spaceport America, the launch site in New Mexico, is authorized for both. Michigan is one of several states, including Alabama and Maine, that are actively pursuing plans to develop spaceports and related facilities, in hopes of creating their own space-industry equivalents to Silicon Valley.

On August 30, 2021, hundreds of satellite- and rocket-makers, venture capitalists, lawyers, and consultants gathered at a luxury resort and spa near Lake Michigan for a three-day event, sponsored by mama, called the North American Space Summit. “Welcome to the Space Gold Rush!” the brochure for the summit proclaimed. The conference offered sessions on subjects such as “Highways in Space,” “Cryptocurrency in the Space Economy, “More Spaceports, More Opportunities,” and various technical and financial aspects of the space industry. One of the speakers was Michelle Lucas, a former astronaut trainer for the International Space Station, and the founder of Higher Orbits, a nonprofit that uses space to get students interested in stem. Lucas wore a midnight-blue dress covered with stars, planets, and swirling galaxies. “I like to think I’m your biggest cheerleader for Michigan space,” she told the crowd. “When I talk to my colleagues, in the industry, especially in the human-spaceflight industry, they have no idea what’s going on out here.” She added, “Spaceports in the Midwest—I am all about it!”

mama’s spaceport plan is not the first effort to launch rockets from the Upper Peninsula. In the mid-sixties, the University of Michigan led a project to launch small experimental rockets for meteorological research from the tip of the Keweenaw Peninsula, a finger of land pointing into Lake Superior about a hundred and twenty miles northwest of Marquette. Most of the rockets were only a few feet tall, and some of them were launched from buoys floating on the lake. But, in 1970, nasa provided two twenty-eight-foot rockets, called the Nike-Apache, for an on-land launch, scheduled for mid-December.


The Keweenaw Peninsula often receives more snowfall than any other area in the U.P., and that winter was no exception. After equipment delays throughout December, a blizzard brought multiple days of heavy snowfall. The first Nike-Apache finally launched, successfully, on January 29, 1971. Soon after, the rocket range was closed. Funding had dried up, and interest evaporated; the Keweenaw Peninsula was likely too remote, the weather too brutal.

Sustaining Lake Superior,” the environmental historian Nancy Langston describes how a single mining company dumped more than four hundred million tons of iron tailings into the lake during the twentieth century. On the Canadian and American shorelines, paper mills once used the lake as a receptacle for waste replete with pollutants. “Sediments contaminated with legacy pollutants still lurk in estuaries and river mouths, and storms churn those old contaminants back into the water,” Langston writes. “The past refuses to stay in the past.”

Grassroots activism and environmental laws have helped to protect Lake Superior from further pollution. The federal Clean Water Act, as amended in 1972, regulates quality standards for ground and surface waters in the United States, authorizing pollution-control programs, including for industrial wastes. In the same year, the U.S. and Canada ratified the Great Lakes Water Quality Agreement; one of the agreement’s stated goals is to prevent harmful discharges from ships and other vessels. Carl Lindquist, the executive director of the Superior Watershed Partnership and Land Conservancy, a nonprofit agency in Marquette that is focussed on, among other causes, protecting the three Great Lakes that touch the U.P. shoreline, told me, “The agreement is a milestone document, but it still has serious loopholes,” including a lack of clear accountability and enforcement. “In short, people are still calling for consistent, effective and easy-to-understand protection measures for Lake Superior,” Lindquist said.


Nowadays, the lake is known for being stunningly clear, with underwater visibility up to a hundred feet in some places. Scientists have shown that a single drop of water can stay in the lake for a hundred and ninety-one years; this is true, as Langston points out, for contaminated water, too. Those drops travel throughout the Lake Superior watershed, which reaches into Canadian territory. Some fear that mama’s spaceport plan might turn the lake into a dump for rocket refuse; there are also concerns that the sheer noise from the launches could trigger wildlife migration, including a disruption of bald-eagle habitats. (mama said that, under an F.A.A. license, it will be required to have an environmental-mitigation strategy and claimed that noise from launches would be “temporary, infrequent, and only loud enough to result in minor impacts like disruption of conversations.”) Residents also worry that the percussion of a launch might weaken the sandstone cliffs along the lake’s shore. Jeanne Baumann and Ray Nurmi’s home is built on a portion of the sandstone that stretches up to Thoneys Point at Granot Loma. This past June, a roughly two-hundred-foot chunk of sandstone cliff at Pictured Rocks National Lakeshore, about fifty miles east of Marquette, spontaneously broke away and crashed into the lake; a similar collapse occurred in 2019.

While driving through the area, I saw dozens of “Protect Lake Superior” signs that included a URL for a Web site called StopTheRocket.com. The signs had been nailed to trees, planted in beaches, and staked into the gravel driveways of camps and houses; they also dotted the roadside along Lake Independence, a lake in Powell Township near the Superior shore. The signs were distributed by a nonprofit organization called Citizens for a Safe & Clean Lake Superior, which was founded in 2020 by Dennis Ferraro, a retired lawyer who lives on Eagles Nest Road. His group, part of a growing opposition to the spaceport initiative, recently put up a giant “stoptherocket.com” billboard on U.S. Highway 41, a major thoroughfare in the U.P.

This past November, Ferraro received a letter from a law firm representing Baldwin. It accused Ferraro’s nonprofit of copyright and trademark infringement, owing to the fact that his organization’s Web site had used Granot Loma’s name and featured a link to an article with details about the property, as part of what Baldwin calls a fund-raising campaign to oppose the spaceport. The letter demanded that the reference to Granot Loma be removed and that any money from the campaign be turned over to Baldwin. “My lawyers laughed,” Ferraro told me.

Lindquist’s agency received a similar letter from Baldwin’s attorney, after referring to Granot Loma on its site in conjunction with the same so-called campaign. Here, too, Baldwin wanted the reference removed and demanded that any money raised be remitted to him. Instead of challenging Baldwin, the nonprofit complied, sending Baldwin’s lawyers a check for fourteen hundred dollars. “As a nonprofit, we simply don’t have the time or funding to be legally bullied by a millionaire,” Lindquist told me in an e-mail. “We have better things to do.”

One of mama’s feasibility studies, published in September, 2021, states that it is “important to engage in public engagement and awareness campaigns throughout the project.” But residents I spoke with complained about what they said was mama’s failure to share information, especially with those who live in Powell Township and the area around Granot Loma. “We are very discouraged that mama has never come to the township with any of their ideas,” Darlene Turner, the township’s supervisor, told me over Zoom. Turner was not invited to the announcement ceremony in Marquette; she learned about the launch-site selection in the newspaper. “It’s very frustrating,” she said. “We were told mama would come to the township in June. And then it was July. But that never happened and still hasn’t happened.” (mama said it never promised to meet with the township and said that it would consult “all necessary officials” during the licensing process.) When I spoke with another resident, she asked, of mama, “What are they afraid of?”

Mama’s most compelling argument for building the spaceport has been an economic one. At the announcement ceremony, Brown said that a launch site in the U.P. would facilitate “a vibrant, robust space industry that will be contributing to hundreds of jobs.” Gerry Corkin, the chairman of the Marquette County Board of Commissioners, told the audience that the plan was a “home run for Marquette County.” Corkin said, “Usually, these things don’t happen in the U.P. You might get close, but you don’t ever seem to grab the brass ring on a big development.”

When I spoke with residents who were supportive of the spaceport plan, they typically cited the jobs argument. Bill Ford, a member of Powell Township’s advisory committee, who is seventy and worked for thirty years at General Motors, said that he is more receptive to the plan than his neighbors, explaining that he would like to see the Michigan Launch Initiative bring jobs to the area. “I’m generally supportive as far as the jobs and what they could offer the township,” he said, of mama, “if they can come up with a good package that gives our citizens a better life.”

mama has published more than twelve hundred pages of feasibility reports on its Web site. One report is titled “Vertical and Horizontal Business Case,” which, at four pages, is the shortest of the documents. According to the report, the capital investment to equip the facilities and infrastructure at the two launch sites is roughly two hundred and ninety million dollars across ten years, from 2023 through 2032. (According to Brown, the majority of the investment is expected to come from the private sector.) The report estimates that the sites will generate a “gross direct, indirect and induced economic impact” of a little more than thirteen billion dollars during that same period. The spaceports, it claims, could attract approximately thirty aerospace and space companies and twenty-six hundred jobs by 2032. The report also states that the Michigan Launch Initiative will have created six hundred and fifty new jobs by the end of 2023—the year that the command-and-control center is expected to commence operations. Those projections differ starkly from the information that Gavin Brown recently provided me in an e-mail; mamanow estimates that the initiative will create six hundred and fifty jobs in total.

Another argument for building a spaceport is that it would draw space-industry talent to the region. Last October, at a café in downtown Marquette, I met with Adam Kall and Austin Morris, two twenty-five-year-old space-industry entrepreneurs. Along with Morris’s brother Troy, who is twenty-eight, they had founded a company that is developing technology to find and retrieve the debris of space missions—defunct satellites, spent rockets, items accidentally released by astronauts—that could cause catastrophic damage in a collision with spacecraft. The three men are graduates of Northern Michigan University, in Marquette. “Adam and I both have enormous three-foot-long Lego sets of the Saturn V in our offices,” Morris said. “All three of us, since we were children, were fascinated with space,” Morris told me. After graduating from N.M.U., they left the U.P. for jobs elsewhere, though they hoped to eventually return.


“We wanted to get back to the U.P., and we wanted to work in space,” Morris said. “What were the options for that? Then we heard about this thing called the Michigan Launch Initiative.” They started to think about how they could make use of a launch site near Marquette. After throwing out some ideas, they decided to try solving the problem of space debris. Their company, Kall Morris Inc., is in the early stages of making a spacecraft that would ride a rocket into orbit and locate debris; a machine-learning algorithm would enable their spacecraft to secure the debris with a robotic arm. “We’d be a rideshare payload,” Kall said. “We’re buying a seat on the plane, jumping on a rocket that is going close to the debris. We’ll have the engine that will move to where the debris is.”

Kall and the Morris brothers represent one type of worker—young, educated, space-age-savvy—that Michigan Launch Initiative proponents hope to attract to the state. As we talked, their geeky passion for all things space was infectious. I found myself thinking, Who wouldn’t have confidence in these hyper-bright individuals attacking the problem of space debris? These men would certainly benefit from a U.P. vertical-launch site. They have participated in some of mama’sevents: Troy Morris, the director of operations for the company, spoke in support of the Michigan Launch Initiative at mama’s courthouse announcement, saying, “This is an exciting potential to launch from the relative back yard of assembly.” Meanwhile, Adam Kall was one of the presenters at the “Highways in Space” session at mama’s space summit. During our meeting, however, Kall and Austin Morris acknowledged the polarizing nature of mama’s project and expressed concerns with the group’s approach to communicating with the public.

“As space nerds, we want a rocket site here, but it’s actually not crucial to our mission,” Morris said. Launching from the U.P. would be convenient, he said, but “we’re going to be shipping the spacecraft to wherever the rocket is launching anyway.” He added that, speaking as a citizen of Marquette, he’s waiting for mama to release more details about its plans: “I think it’s up to mama to put out the actual truth about what the scenario is going to be in order to dispel all rumors.”

“Or to confirm the rumors,” Kall said. “I think mamadrastically underestimated the ability of Yoopers to get worked up about something, to be passionate about something,” he said, using the nickname for residents and natives of the U.P. “We’ve seen it many times when someone discounts the U.P. as a bunch of hillbillies up here who have nothing to do.”

Last October, when I met with Dennis Ferraro, who runs the organization responsible for the “Protect Lake Superior” signs, he told me, “I don’t think mamahas been completely forthright.” That comment turned out to be prescient. In November, Ferraro reviewed hundreds of pages of documents that he obtained through a public-information request to the Michigan Economic Development Corporation, the agency that administers and monitors the grant that mama received to fund its feasibility studies. Among the materials was a hundred-and-forty-eight-page draft report titled “Michigan Space Launch Report,” written by a nonprofit scientific organization, I.Q.M. Research Institute, and dated February, 2021. Although the document was commissioned by mama, its existence had not been made public, and it is clear why mamamight not have wanted it to be seen. The report refers to investments in the Michigan spaceport as “high risk and low return.” Between 2018 and 2020, the report says, “seven of the thirteen U.S. spaceports had no revenue-producing launch activity.” (The F.A.A. told me that only five of the licensed spaceports have ever seen a launch.) And, according to I.Q.M., none of the non-government-funded spaceports—meaning commercial spaceports like the one that mama wants to build in Michigan—“enabled any meaningful economic growth in the new space economy.” The report concludes that the business case for vertical- and horizontal-launch sites in Michigan is “uneconomical,” and recommends that no investment be made in these facilities. Instead, I.Q.M. advises that Michigan invest in space by rebranding and accelerating space technologies and programs in the state’s economy, such as space-data analytics.

Perhaps the most striking comment in the report—and potentially the most damaging to mama’s efforts to promote the idea of a spaceport for Michigan—is a line from the executive summary: “the annual revenue generated from a launch cadence of one rocket launch per week in Michigan would have the same revenue impact in the State equal to the annual revenue of two additional fast-food chain restaurants.” The I.Q.M. report is a stunning counter-argument to the claims in the studies that mama published, including one in which both launch sites are deemed “not only technically feasible but also feasible in economic and financial terms.”

I.Q.M. Research Institute is a nonprofit organization that provides research and analysis for the government and industrial clients. The institute states in its report that it analyzed historical data and spoke with more than eighty senior executives, military leaders, and other experts within the space industry, including those at academic institutions, private spaceport operators, vertical- and horizontal-launch-system providers, think tanks, and other organizations. In contrast, the feasibility studies that mama put on its Web site were conducted by three for-profit consulting companies: B.R.P.H., which was referred to in a brochure for mama’s space summit as an “Official Architecture, Engineering and Construction Consultant for Michigan Launch Initiative,” as well as Kimley-Horn, and InterFlight Global. Kimley-Horn and B.R.P.H. were two of several sponsors of mama’s space summit, and representatives from both spoke at the conference.

When asked about the I.Q.M. report, mama said that it never asked the institute to look into the economic feasibility of the Michigan Launch Initiative, and that I.Q.M. provided recommendations that it was not “qualified” to give. mama also alleged that, unlike its other consultants, I.Q.M. failed to provide its sources, which prevented mama from being able to independently verify the report’s findings. Some of I.Q.M.’s recommendations were “self-interested,” mama added, space-data analytics being “one of the services it sells.”

Mike Dudsik, the president of I.Q.M. and a retired general with more than two decades of experience developing space programs, rejected mama’s claims, including the allegation that I.Q.M. had a financial interest in its recommendations about space-data analytics. “The people who worked on this report were engaged every day in the space economy and are some of the leading experts in space economic policy,” he said, adding that I.Q.M. routinely briefed mama on the meetings it was having with sources who contributed to the report.

At Granot Loma, Baldwin made a comment that stuck with me as I thought about the human history of Lake Superior. We had been discussing the difficulty that his neighbor to the north had encountered in selling his property of a hundred and seventy acres, with a shoreline of mostly rocky outcroppings. “Lake Superior is not really usable,” Baldwin had said. “Other than for the view.” It was an off-the-cuff remark from an entrepreneur and a potential co-developer of a spaceport, but it also just wasn’t true.

Marquette residents have been drinking Lake Superior water for more than a hundred and forty years; a filtration plant produces about three million gallons of water daily. The lake also serves as a shipping lane between ports such as Thunder Bay, Ontario, and Duluth, Minnesota, and the locks at Sault Ste. Marie, Michigan, which enable vessels to enter the lower Great Lakes and to sail along the St. Lawrence River to the Atlantic Ocean. Roughly seven thousand ships pass through the locks every year. One afternoon, I looked at a Web site that tracks, in real time, the number of vessels on Lake Superior and their destinations. (I was aware that the real-time ship-tracking data were made possible, in part, by a satellite sent into space by a rocket.) There were twenty-six ships when I checked, and many were travelling in the lake’s southern half, to and from Duluth, around the Keweenaw Peninsula, and along a path following the U.P.’s shoreline toward the locks—a passageway that might be restricted during a rocket launch at Granot Loma.


An online petition opposing the spaceport has nearly twenty-five thousand signatures, most from residents of Michigan, Wisconsin, and Minnesota—states with Lake Superior shoreline. By late last year, even some of the residents who’d initially been supportive of mama’s plan had begun to sour on it. Last October, Gerry Corkin, the chairman of the Marquette County Board of Commissioners, who’d originally called the plan a “home run,” seemed to have become disillusioned with mama. “They haven’t been up here talking to the public about it and making the tentative plans clear to people who live here,” he said. “To me, if you have a problem with people who have negative thoughts about what you’re going to do, you need to get up and talk to Powell Township and pay attention to their questions.”

Meanwhile, Baldwin’s attitude toward the plan’s opponents was not exactly neighborly, even though he has lived in Powell for thirty-five years. “Opposition to the spaceport is primarily senior citizens who are retired,” he told me. “They’re afraid of what the spaceport might bring in terms of people.” He went on, “Everything else you’ve heard is just smoke to stop it.” Baldwin seemed to miss a conspicuous distinction between himself and his generational peers—for he, too, is a senior citizen—who live in the area: his wealth and his power to negotiate with space-industry players. Baldwin, for his part, said that he would not move if a spaceport is built at Granot Loma. That’s one thing he has in common with his neighbors. “This is my last resort up here,” Dennis Ferraro, who is seventy-five, told me. “I’m not going anywhere. They’re going to scatter my bones or ashes on this property. I’m committed to leaving this land for people a hundred years from now. Hopefully, it will look the same.”
tl;dr
Fuck *ichigan. Instead of making it the next Space State, launch the whole state into space.

MORNING PLANETS: This is a great week to wake up early and look at the planets. They're all lined up. Daniel Mello sends this picture from his garden in Rio de Janeiro, Brazil:
aAyt6f5.jpg

"This is a simple 5 second exposure with my Canon EOS 500D camera (ISO 800)," says Mello. "It was a beauty planetary sequence just before sunrise. The sky colors topped it off!"

The display is about to get even better. Venus and Jupiter are converging for a tight conjunction on Saturday morning, April 30th. They will "appear to nearly collide into each other," according to NASA. "Due to the glare from both planets, some observers will see them merge into one very bright, spectacular glow!"

Between now and then, the crescent Moon will glide by Venus and Jupiter, forming a lovely triangle on Tuesday morning, April 26th, and especially Wednesday morning, April 27th. Set your alarm for dawn (60 minutes before local sunrise) and enjoy the show.

Fireball! Scientists advise meteorites may be scattered across southern Ontario
By Stefanie Waldek published 2 days ago

Western University and the Royal Ontario Museum are asking for Ontarians to report "suspicious rocks."

If you live in Ontario, keep your eyes peeled for "suspicious rocks."


On Sunday (April 17), skywatching cameras in the Canadian province recorded a massive fireball that likely produced tens to hundreds of grams of meteorites. Astronomers predict they would have fallen on the eastern shore of Lake Simcoe, north of the town of Argyle.

asteroidal orbit, and ended very low in the atmosphere. These are all good indicators that material survived," Denis Vida, an astronomy postdoctoral associate at Western University who specializes in meteors, said in a university statement.

Astronomers have used the footage to determine that the fireball became visible at an altitude of around 60 miles (90 kilometers), traveled due north at a sharp angle just 30 degrees from vertical, and continued to burn as low as 18 miles (23 km) in altitude. "Taken together, these factors suggest many small meteorites have made it to the ground," said Vida.

As such, Western University and the Royal Ontario Museum are asking residents in the area of the suspected meteorite fall zone to report any "suspicious rocks" they may find by sending an email to [email protected]. (Worth noting — in Canada, meteorites technically belong to the owner of the land on which they fall.)

Meteorites typically have a dark color and a scalloped texture, and they are also quite dense. If you find one, store it in a plastic bag or wrap it in aluminum foil — the meteorite itself poses no danger to humans, but scientists prefer to keep them as uncontaminated as possible.

"Meteorites are of great interest to researchers as studying them helps us to understand the formation and evolution of the solar system," Vida said.

The Smithsonian and Meta are teaming up to let you experience the moon in VR
Stitching together thousands of archival photos and audio samples, the exhibit will let visitors walk in the Apollo astronauts’ shoes.

https://www.fastcompany.com/9074419...aming-up-to-let-you-experience-the-moon-in-vr
Visitors to the Smithsonian Institution will soon be one small step closer to virtually walking on the moon.

A new partnership between Meta and the Smithsonian’s Arts and Industries Building on the National Mall will let visitors don a Meta Quest 2 VR headset and experience the 1969 Apollo 11 mission that sent Neil Armstrong and co. to the moon. Participants will first be placed in the Eagle spacecraft, and will then be able to walk on the moon’s surface.

“You can literally walk around and look and see the lunar buggy next to you and look down and see the rocks and look at the horizon,” says Rachel Goslins, director of the Arts and Industries Building. “It has literally never been possible, unless you were an astronaut, to experience the moon this way.”

The “Moonwalk” exhibit, which opens May 4, comes as museums around the world are exploring ways to use virtual reality technology to tell stories and engage with visitors, and as the Smithsonian promotes the recently revamped Arts and Industries Building with a renewed focus on exploring the future. While VR technology may be new, Goslins emphasizes the building and the Smithsonian have long played a role in introducing people to science and technology of both Earth and space. “The museum is like the original immersive experience,” she says.

The exhibit is part of an ongoing series exploring potential “artifacts of the future.” It relies on more than 7,000 photos taken by NASA astronauts on missions to the moon, stitched together and converted to 3D imagery by humans and AI software through a process called photogrammetry.


“There’s just a very large collection of scanned objects that are able to be accessed through our technology,” says Monica Arés, head of Meta Immersive Learning, a company initiative providing $150 million in funding for metaverse and immersive experience projects.

Visitors will also be able to hear conversations between astronauts and Mission Control staff as they explore the digital exhibition. “They banter with each other; it just makes it so human,” Goslins says.

This won’t be the first time the Arts and Industries Building, first opened as the National Museum in 1881, lets visitors learn about the lunar expeditions of the 1960s and ’70s. Just a few weeks after the Apollo 11 mission in 1969, Goslins says, visitors were able to see a rock retrieved from the lunar surface.

“It was this mind-blowing experience for people,” she says. “A little bit later we actually had the Apollo command module and lunar lander in the building.”

As museumgoers wait to enter “Moonwalk,” they’ll also be able to use augmented reality technology to explore the historic lunar command module as it sat in the building on display in the 1970s, and can take a virtual selfie in a digitized astronaut helmet.

The Smithsonian and Meta previously worked together on a virtual tour of Venice available online, though “Moonwalk” marks their first in-museum collaborative exhibition.

Arés emphasizes the ability of VR to let people experience immersion in a particular place and time. “It allows you to walk in other people’s shoes,” she says, “just like being able to walk with the astronauts who were able to go up to the moon.”

Meteorites could have brought all 5 genetic 'letters' of DNA to early Earth
By Charles Q. Choi published 1 day ago
These key building blocks of life were found in space rocks, scientists confirm.

https://www.space.com/meteorites-brought-dna-blocks-to-early-earth
Key building blocks of DNA that previous research mysteriously failed to discover in meteorites have now been discovered in space rocks, suggesting that cosmic impacts might once have helped deliver these vital ingredients of life to ancient Earth.


DNA is made of four main building blocks — nucleobases called adenine (A), thymine (T), cytosine (C) and guanine (G). DNA's sister molecule, RNA, also uses A, C and G, but swaps out thymine for uracil (U). Scientists wondering whether meteorites might have helped deliver these compounds to Earth have previously looked for nucleobases in space rocks, but until now, scientists had only detected A and G in space rocks, and not T, C or U.

Nucleobases come in two flavors, known as purines and pyramidines. The nucleobases previously seen in meteorites are both purines, which are each made of a hexagonal molecule fused with a pentagonal molecule. The ones missing in space rocks until now are pyramidines, which are smaller structures each made of just a hexagonal molecule.

It was long a mystery why only purines, not pyramidines, were seen in meteorites. Prior lab experiments simulating conditions in outer space suggested that both purines and pyramidines could have formed during light-triggered chemical reactions within interstellar molecular clouds, and that the compounds could then have been incorporated into asteroids and meteorites during the formation of the solar system. Such chemical reactions may have also happened directly within the space rocks.


Now, scientists have finally detected all the pyramidines and purines found in DNA and RNA in meteorites that made it to Earth.

"The presence of the five primary nucleobases in meteorites may have a contribution to the emergence of genetic functions before the onset of life on the early Earth," study lead author Yasuhiro Oba, an astrochemist at Hokkaido University in Japan, told Space.com.

The researchers employed state-of-the-art analytical techniques originally designed for use in genetic and pharmaceutical research to detect tiny amounts of nucleobases, down to range of parts of per trillion. This is at least 10 to 100 times more sensitive than prior methods that attempted to detect pyramidines in meteorites, Oba said.

The scientists analyzed samples from three carbon-rich, or carbonaceous, meteorites that prior work suggested could have hosted the kinds of chemical reactions that created nucleobases — the Murchison, Murray and Tagish Lake meteorites.

The scientists detected T, C and U at levels of up to a few parts per billion within the meteorites. These compounds were present at concentrations similar to those predicted by experiments replicating the conditions that existed prior to the formation of the solar system. In addition to the crucial T, C and U compounds, the scientists also detected other pyramidines not used in DNA or RNA that further show meteorites' ability to carry these compounds.

"Due to our findings, we can say nucleobases also show wide varieties in carbonaceous meteorites," Oba said.

It remains uncertain why pyramidines were so much less abundant in these meteorites than purines. Oba suggested a clue might lie in the fact that purines include a pentagonal ring known as imidazole, whereas pyramidines do not.

Imidazole and similar molecules proved far more abundant than pyramidines in these meteorites, suggesting they might prove easier for naturally occurring chemical reactions to synthesize. In addition, imidazole can act like a primitive catalyst to set off chemical reactions, such as forming purines instead of pyramidines.

The scientists detailed their findings online April 26 in the journal Nature Communications.

A Falcon 9 lifts off April 27 on the Crew-4 mission to the International Space Station

Falcon 9 launches Crew-4 mission to space station
by Jeff Foust — April 27, 2022
https://spacenews.com/falcon-9-launches-crew-4-mission-to-space-station/
WASHINGTON — Four American and European astronauts are on their way to the International Space Station after their launch on a Crew Dragon spacecraft April 27, less than two days after another spacecraft returned from the station.

A SpaceX Falcon 9 lifted off from Launch Complex 39A at the Kennedy Space Center at 3:52 a.m. Eastern, placing the Crew Dragon spacecraft Freedom into orbit 12 minutes later. The rocket’s first stage, which launched three previous missions including Crew-3, landed on a droneship in the Atlantic.

The Crew-4 mission is commanded by NASA astronaut Kjell Lindgren with Bob Hines as pilot. NASA astronaut Jessica Watkins and European Space Agency astronaut Samantha Cristoforetti are mission specialists. The Crew Dragon is scheduled to dock with the ISS at 8:15 p.m. Eastern, a little more than 16 hours after liftoff.

Freedom will use the same ISS docking port that was occupied just a few days earlier by another Crew Dragon spacecraft, Endeavour, that spent more than two weeks at the station for the Ax-1 private astronaut mission. The spacecraft undocked April 24 and splashed down off the Florida coast April 25, less than 39 hours before the Crew-4 liftoff.

Both NASA and SpaceX officials said the short turnaround between the Ax-1 splashdown and Crew-4 launch was not an issue. “Engineers have been pouring over the data over the last 18 hours,” Steve Stich, NASA commercial crew program manager, said at a prelaunch briefing April 26 of reviews from the return of the Ax-1 mission. “It’s been a clean flight overall. No major issues.”

NASA and Roscosmos also worked to squeeze in the arrival of Crew-4 around a spacewalk by two Russian cosmonauts, Oleg Artemyev and Denis Matveev, scheduled for April 28. Joel Montalbano, NASA ISS program manager, said at the prelaunch briefing that the traditional welcome ceremony for the Crew-4 astronauts will take place several hours after their arrival because the Russian cosmonauts will be asleep at the time of docking to stay on schedule for their spacewalk.

NASA is planning a five-day handover between the new Crew-4 astronauts and the departing Crew-3 astronauts, who have been on the station since November 2021. Those four astronauts — NASA’s Raja Chari, Tom Marshburn, Kayla Barron and ESA’s Matthias Maurer — will depart in early May on the Crew Dragon spacecraft Endurance.

The Crew-4 astronauts will remain on the station until September. The Crew-5 mission, set to use the same spacecraft, Endurance, as Crew-3, will launch that month, with Crew-4 expected to return by mid-September, shortly before the launch of the Soyuz MS-22 spacecraft. Crew-5 and Soyuz MS-22 may feature a seat exchange between an American astronaut and a Russian cosmonaut, if an agreement is completed by June.

A hectic schedule will continue after Crew-4’s arrival with a second uncrewed test flight of Boeing’s CST-100 Starliner commercial crew vehicle, scheduled for May 19. A SpaceX cargo Dragon mission to the station will follow in June. Those missions may have to work around new attempts to perform a wet dress rehearsal of the Space Launch System.

“Spaceflight tends to be a magnet of dynamic activities,” Montalbano said at the prelaunch briefing. “They all tend to draw together.”

THE SODIUM TAIL OF MERCURY:
Planets aren't supposed to have tails, but Mercury does. Dr. Sebastian Voltmer just photographed it from La Palma in the Canary Islands:
vXpfj08.jpg

"This is NOT a comet, not even a meteor, but the planet Mercury, which is currently very close to the Pleiades," says Voltmer. "How is the tail formed? The solar wind and micro-meteorites eject sodium atoms from Mercury's surface. This creates a yellow-orange tail of sodium gas that is around 2.5 million kilometers long."

People around the world have been watching Mercury climb up the evening sky this month. Some of them are probably wondering "why didn't I see the tail?"

Answer: A special filter is required. "I used a 589 nm filter tuned to the yellow glow of sodium," says Voltmer. Without this kind of sodium filter, Mercury's tail would be invisible.

Voltmer says the tail is so bright, he could see it in individual 30 second exposures. "I can see some very small changes in shape of the tail," he says, "and the brightness is slightly increasing."

The nights ahead are excellent times to catch this phenomenon. On April 29th and 30th, Mercury will glide past the Pleiades star cluster for a fantastic photo-op. Then, on May 1st and 2nd, the crescent Moon joins the show.

"Currently I'm imaging Mercury day by day just after sunset from the Canary Islands," says Voltmer. Stay tuned for more sodium.

Isotropic Is on Hiring Binge
By Ryan Duffy
Terminal-in-Chamber-1.png

https://payloadspace.com/isotropic-is-on-hiring-binge-as-production-scales/
Isotropic Systems has doubled in size over the last year, just recently signing its 130th hire, and expects to 2X again in the coming year, the British startup told Payload.

The Reading, UK-based company has created—and successfully field-tested—a potentially revolutionary technology: multi-beam, multi-link, and all-orbit satellite terminals.

Origin story
In 2013, Isotropic CEO and founder John Finney set out to “simply just do make-before-break connections,” Brian Billman, the company’s chief marketing officer, told Payload. Make-before-break = linking with a rising satellite on the horizon before terminating a connection with one that is moving out of sight. Simple in theory, but not so simple in practice.

Isotropic engineers and scientists spent years of R&D and tens of millions of dollars to get here. Isotropic had to work through bleeding-edge technology, difficult physics equations, and…Mother Nature. The short, non-PhD version of this story includes transformational optics, metamaterials, and negative refractive indexes…some of the same tech that could theoretically go into invisibility cloaks, Billman said.

But, there’s always a but.

“When you solve those equations, typically what you end up with is material that does not exist in nature [or] real life,” Billman said. “That can be a problem when you’re trying to carry a real product and sell it and make money.”

Isotropic’s breakthrough, Billman said, was to pair transformational optics with common commercial manufacturing techniques and radiofrequency (RF) lenses that are “easily manufacturable, extremely low-loss, and extremely broadband.” How about that timing? Not only did Isotropic reach the make-before-break mecca, it also developed a way to “talk” with the birds in their various roosts.

Satellites are increasingly migrating to NGSO (non-geostationary) homes in low, medium, and highly elliptical (LEO, MEO, HEO) Earth orbits. Big, traditional parabolic dishes won’t be able to fully tap all the new capacity that is coming online, Billman said. Isotropic’s pitch = the antenna will be able to leverage all those new constellations in new places, without any sacrifices in bandwidth, latency, and the like. Going to market Billman said multi-link, multi-orbit capabilities offer sizable boosts in throughput, efficiency, and resiliency.

Use cases range from cellular backhaul to in-flight connectivity to bolting terminals onto special operation forces’ tactical vehicles. While Isotropic aims to sell into multiple markets, it’s currently feeling the strongest pull from government customers, who place a premium on resiliency and aren’t as price-sensitive.

Billman said multiple military and government customers have said: “Look, as soon as that is out from your production line, I don’t even want to demo and trial it. I want to get it out in the field.”

Production terminals are sold out for the rest of 2022, and the backlog is starting to stretch well into 2023. Billman wouldn’t divulge any specifics on pricing, so as to not tip off the competition. But it’s safe to assume Isotropic’s antennas, which are split among multiple product lines, aren’t retailing for the price of Starlink’s Dishy.

What next?

Isotropic is going after a huge market and pitching itself as the ground infrastructure provider for the 2020s. The next big hurdle, it seems, will be reaching volume production and starting to accommodate the “insatiable demand.”

And…finding talent. As it grows, Isotropic’s recruiting efforts are focused on manufacturing and software development roles.

NASA and DLR Terminate SOFIA
By Rachael Zisk
OBS_0035.jpg

It’s official: NASA and German space agency DLR have agreed to end operations on the expensive airplane-mounted infrared observatory this year.

NASA has been trying to cut the line item from its budget for a few years now, but for the past two years, Congress has restored the observatory’s funding in the agency’s federal budget. SOFIA is an expensive project, chewing up ~$85M per year for “modest scientific productivity,” per Astro2020. In November, the decadal survey’s authors recommended that NASA terminate the project.

SOFIA: The Stratospheric Observatory for Infrared Astronomy basically consists of a 2.7m infrared reflecting telescope mounted on a Boeing 747 aircraft. It’s used in a similar way to a ground observatory, but by flying above 99% of the infrared-blocking atmosphere, it can provide a unique vantage point for astronomers to observe the universe.

SOFIA performs 10-hour overnight flights, collecting infrared data from distant objects in space. Arguably, SOFIA’s most significant achievement was identifying water on the sunlit surface of the Moon.

  • The observatory has been operating for the past eight years, and had an original mission duration of five years.
  • 70 more flights are planned before the craft is officially retired at the end of September.
Missing the mark: While SOFIA has been a unique program for NASA and for the astronomers that utilize it, it just doesn’t keep up with the productivity standards needed to justify its $85M a year price tag. Plus, other ground-based and orbiting telescopes can fulfill the same science needs for the US space agency and astronomers.

DLR covers 20% of program costs for SOFIA each year, so NASA needed the German agency’s sign-off to terminate the observatory’s operations. DLR has agreed to an orderly shutdown of the project at the end of its current mission extension.

X-CLASS SOLAR FLARE:

jvLtS1g.gif

So long, and thanks for the X-flares. Departing sunspot AR2994 unleashed another X1-class solar flare today, April 30th @ 1347UT, as it exited the Earthside of the sun. NASA's Solar Dynamics Observatory recorded a spectacular plume of debris flying up and over the sun's northwestern limb.

Even with the sunspot completely hidden behind the edge of the sun, the explosion still produced enough radiation for a strong shortwave radio blackout over the mid-Atlantic Ocean and much of Europe: map. Signals below 30 MHz were attentuated for nearly an hour.

This flare almost certainly produced a coronal mass ejection (CME). Images from SOHO coronagraphs (when they become available) will likely confirm that the CME won't hit Earth--a result of the sunspot's farside location. Stay tuned.

A TIGER ELVE OVER TEXAS:
For a few milliseconds last Friday night, an enormous (100 km wide) red ring of light appeared over west Texas. Thomas Ashcraft photographed it from across the state line in New Mexico:

This is an "ELVE"--short for Emissions of Light and Very Low Frequency Perturbations due to Electromagnetic Pulse Sources. It's a rare species of sprite discovered in 1990 by cameras onboard the space shuttle. Ashcraft may have just taken the best ever picture of one from the ground.

"The ELVE was generated by a super-strong lightning stroke that occurred over west Texas near the town of Borger at April 28 2022 0439:10.5326 UT," says Ashcraft. "Note also the sprite elements at the bottom of the ELVE."

The lightning bolt was so strong, it generated an intense electromagnetic pulse (EMP). The red ring marks the spot where the EMP hit Earth's ionosphere. Normal lightning bolts carry 10 to 30 kilo-ampères of current; this bolt was about 10 times stronger than normal.

"The lightning stroke that manifested this event registered on VLF radios at least as far away as Germany," notes Ashcraft. "You can actually hear the lightning stroke in my video."

Bonus: This is also a Tiger ELVE. Note the linear corrugations across the red ring. These are impressed on the ELVE by gravity waves in the upper atmosphere. Like a tiger, this ELVE has stripes.

Propulsion Startups Raise Series A

A sudden rush of capital is flowing into a sector that, until recently, seemed stagnant: independent propulsion providers. Last week, Firehawk Aerospace, Adranos, and X-Bow Systems, each horizontally integrated propulsion systems developers, announced Series A rounds totaling at least $47M.

Firehawk Aerospace
Last week, Firehawk announced that it had received a Series A investment from Raytheon. The two companies are partnering on R&D for a hybrid engine for missile propulsion.

  • The company is building custom rocket engines that are ready to ship within 4-6 months. Engines are made using only 20 components, and Firehawk claims its product costs only a fifth of comparable engines. The startup lowers fuel production costs by 3D-printing its solid fuel.
“There needs to be more competition” in propulsion, Firehawk CEO Will Edwards told Payload. “The propulsion industry has seen rapid consolidation over the past few decades, resulting in a lack of innovation. There is plenty of room for competition. In fact, it is necessary.”

Horizontal integration has allowed Firehawk to focus purely on how to build the best engines and allow its customers to innovate on the rest. “Let us do what we do best, you do what you do best, and we can create a much more efficient industry,” Edwards said.

Adranos
The solid rocket engine manufacturer closed a $20M Series A last week from investors including Impala Asset Management LLC, Explorer1 Fund, Elevate Ventures, and Specific Impulse Capital. Adranos’s differentiator is a high-performance proprietary aluminum-lithium alloy fuel called ALITEC.

“The U.S. government views the limited number of firms in the energetics space as a weakness, and our entry will add further resiliency and capability that our nation can rely on,” Adranos VP of space systems Michael Grasso told SpaceNews.

X-Bow Systems
X-Bow Systems, yet another solid rocket engine manufacturer, raised a $27M Series A last week led by Crosslink Capital and Razor’s Edge Ventures. X-Bow offers a solid rocket engine called Ballesta that it says is the “first large-diameter scale motor designed and tested by a non-legacy systems integrator supplier in over 30 years.”

State of the DIB
The defense industrial base (DIB) has drastically consolidated over the last few decades. A February Pentagon report recalled how mergers and roll-ups became commonplace among satellite suppliers and propulsion providers.

  • By 2020, the field of solid rocket motor makers had shrunk to just two providers: Aerojet Rocketdyne and Northrop Grumman (which acquired the capability with Orbital ATK).
  • Aerojet was nearly acquired by Lockheed Martin before the FTC stepped in to block the deal earlier this year, citing worries that there would not be enough domestic competition if the market lost access to Aerojet engines.
Takeway: As Ursa Major CEO Joe Laurienti told Payload last month, lacking competition has produced a lapse of innovation. But now there are new launch and hypersonic motor kids on the block—and they’re angling to kickstart competition in the independent propulsion sector.
