ESA to rent SpaceX Dragon capsule to do a European manned mission to ISS

9:15 am

ESA logo

Capitalism in space: At a European Space Agency (ESA) this week in Switzerland, agency officials announced that it is purchasing use of a Dragon capsule from SpaceX in order to do an extended manned mission to ISS in 2028.

Member states endorsed the concept of EPIC — short for ESA Provided Institutional Crew — a proposed mission intended to provide a medium-duration stay for ESA astronauts aboard the ISS.

The plan foresees acquiring a Crew Dragon mission in the first quarter of 2028 in collaboration with “interested international partners.” Crew Dragon is the crew spacecraft built by US company SpaceX.

According to those officials, this mission will be for at least one month, and include astronauts from ESA and some as yet undetermined international partner astronauts.

This contract illustrates the fundamental shift in power and control in manned space in the past decade. Until 2011, all manned missions were flown on government-built rockets and spacecraft. The agencies controlled everything, and actually acted to stymie competition from the private sector.

Now, those agencies are dependent on that private sector for their manned missions. They are instead merely customers, buying services from competing commercial companies that own the rockets and spacecraft, and rent them out for profit. That SpaceX at present is the only one capable of doing these manned missions for hire makes no different. Soon others will enter the fray.

Moreover, this capitalism model actually gives these agencies more flexibility. Beforehand, ESA had to go through NASA to do such a manned mission, and that would involve a lot of negotiations. Now it simply buys the mission from SpaceX, and flies it when ready.

SLS/Orion have begun 12-hour trip from VAB to launchpad

8:59 am

Artemis-2 mission flight path
The Artemis-2 flight path. Click for full animation.

NASA engineers today began the long and slow 12-hour trip of the SLS rocket from the Vehicle Assembly Building (VAB) to the launchpad in preparation for a targeted April 1, 2026 launch date of this Artemis-2 mission around the Moon.

NASA’s Artemis II SLS (Space Launch System) rocket and Orion spacecraft slated to send four astronauts around the Moon began rolling to Launch Pad 39B at 12:20 a.m. EDT on Friday, March 20. Rollout operations at the agency’s Kennedy Space Center in Florida were delayed earlier in the day due to high winds in the area.

The trek to the pad is expected to take up to 12 hours, as NASA’s crawler-transporter 2 carefully carries the rocket on top of the mobile launcher approximately 4 miles along the crawlerway.

The launch will send four astronauts on a ten-day mission swinging around the Moon and back to Earth, using a questionable heat shield and a life support system not yet been tested in space. On the first unmanned Artemis-1 mission around the Moon in 2022, the shield experienced far more damage than predicted, with large chunks breaking off. NASA engineers think they understand why this happened, and have decided that they can mitigate the problem by using a less stressful flight path upon return into Earth’s atmosphere.

They don’t really know if this is so, but they hope so. As for the life support system, the plan is to remain in a high Earth orbit for the mission’s first day to test it. If it has problems then, the crew will be able to return to Earth somewhat quickly. If it has problems after heading to the Moon, however, that won’t be possible.

If a private company tried to convince NASA to do this mission with these issues, the agency would say “Hell no!” It is proceeding because, like the Challenger and Columbia failures, it is a NASA-built project and politics and schedule have superseded safety and good engineering procedures

Blue Origin files FCC application for its own 51,600 data center satellite

8:01 am

Blue Origin yesterday filed with the Federal Communications Commission (FCC) an application to launch a 51,600 satellite, dubbed Project Sunrise, aimed at creating its own data center constellation in orbit.

The proposed constellation includes up to 51,600 satellites operating in sun-synchronous orbits at altitudes ranging from 500 to 1,800 kilometers. To manage data traffic, the system will primarily use optical links and mesh backhaul networks, supplemented by Ka-band spectrum for telemetry, tracking, and command operations. The spacecraft will utilize multiple antenna variations to maintain efficient coverage across various orbital planes.

You can read the full application here [pdf].

Jeff Bezos
Jeff Bezos, maybe the world’s leader in chutzpah.

Blue Origin also requests several waivers from the FCC’s normal new satellite license requirements, including what I think is a request to waive the FCC’s normal requirement that the applicant launch half its constellation within six years of license approval and complete the constellation three years later. Failure to do so results in financial penalties. The rules were created to prevent companies from getting licenses to grab spectrum from competitors with no intent to launch.

That this Jeff Bezos company is requesting this waiver is what in Yiddish is called chutzpah! Bezos’ other company, Amazon, is clearly going to fail to meet its own license timetable in launching its Leo internet constellation, and was recently lambasted by FCC chairman Brenden Carr for doing so. For Blue Origin to now request this waiver truly is an example of unbelievable gall. I can’t imagine the FCC will do so.

Either way, the competition to put up a lot of satellites continues to grow, with SpaceX and Blue Origin in the best position to make their constellations profitable, because both have their own launch vehicles.

SpaceX completes a Starlink launch

2:14 pm

UPDATE: It appears The Russian launch described below did not occur as indicated by the story I linked to. There is no confirmation anywhere on the web that the launch occurred. If it had, the nature of the payload would have guaranteed some story in Russia’s state-run press. See also this X post, which suggests the lack of information about the scrub is related to Russian concerns about Ukrainian drone attacks.

Original post
———————-
There were two launches today, both of which sent up a cluster of satellites for broadband internet constellations.

First, Russia launched the first 16 satellites in its proposed 700+ satellite Russvet internet constellation, its Soyuz-2 rocket lifting off from its Plesetsk spaceport in northeast Russia. The satellites are built by the Russian company Bureau-1440, which hopes to have the entire constellation in orbit by 2035. Considering that this constellation is designed to compete with Starlink, its pace of launch is ridiculously low. SpaceX can generally launch 700 Starlink satellites in about a month, not ten years. By the time Russia gets this constellation in orbit it will be woefully obsolete.

SpaceX meanwhile proved this point today by continuing its brisk pace in Starlink launches. It successfully placed 29 more Starlink satellites in orbit, its Falcon 9 rocket lifting off from Cape Canaveral Space Force Station in Florida.

The first stage (B1077) completed its 27th flight, landing on a drone ship in the Atlantic, only 26 days after its previous flight. This flight also moved the booster up to just behind the space shuttle Columbia in the rankings of the most reused launch vehicles:

39 Discovery space shuttle
33 Atlantis space shuttle
33 Falcon 9 booster B1067
32 Falcon 9 booster B1071
31 Falcon 9 booster B1063
30 Falcon 9 booster B1069
28 Columbia space shuttle
27 Falcon 9 booster B1077

Sources here and here.

The leaders in the 2026 launch race:

35 SpaceX
12 China
3 Rocket Lab
2 Russia (corrected)

SpaceX continues to lead the entire world combined in total launches, as it did in both ’24 and ’25.

German rocket startup signs deal to launch from SaxaVord spaceport in Scotland

9:56 am

Proposed or active spaceports in North Europe
Proposed or active spaceports in North Europe

The German rocket startup HyImpulse yesterday signed a contract with the SaxaVord spaceport on the Shetland Islands in Scotland to do a suborbital test launch at SaxaVord later this year.

HyImpulse has agreed a launch deal with the Unst spaceport, with the aim of a suborbital launch in quarter three of 2026. It will be the second launch of the company’s SR75 suborbital launch vehicle following a successful lift-off in Australia in 2024, which used a hybrid propulsion system involving paraffin “candle wax” and liquid oxygen. HyImpulse said that initial launch, from Koonibba, showed the vehicle could demonstrate “stable flight validating system performance under operational conditions”.

Under the agreement, SaxaVord will provide launch infrastructure and operational support for the launch of the SR75.

HyImpulse is the second German rocket startup to sign a deal to launch from SaxaVord. Rocket Factory Augsburg plans its second attempt to do an orbital launch from there later this year. In 2024 it was gearing up to do that launch but an explosion during a full static fire test of the rocket’s first stage killed that plan.

Considering the red tape the United Kingdom has imposed on rocket companies, bankrupting two and delaying all launches for years from both SaxaVord and the other proposed spaceport in Sutherland, Scotland, I am surprised these two rocket companies have signed these deals. Maybe the UK’s Civil Aviation Authority (CAA) has been reformed and eased that red tape.

Or maybe HyImpulse will find its plans blocked by the CAA as that agency once again ponders at glacial pace the issuing of a new launch license. Stay tuned.

OHB wins $285 million contract to build weather satellite constellation for ESA

9:36 am

ESA logo

Capitalism in space The Swedish subsidiary of the European aerospace company OHB yesterday announced it has won a $285 million contract from the European Space Agency (ESA) to build and maintain a six satellite weather satellite constellation.

The company had already successfully launched and tested a single demo satellite, proving a small satellite could do the job.

The foundation for this is the Arctic Weather Satellite (AWS), which OHB Sweden successfully placed in orbit as a demonstrator more than a year ago. The OHB SE subsidiary developed the small satellite on behalf of the European Space Agency ESA in record time, using a deliberately chosen New Space approach. Only three years passed between contract award and launch.

This new constellation is dubbed EUMETSAT Polar System – Sterna (EPS-Sterna), and will supplement and eventually replace the expensive government-built Eumetsat weather constellation presently in orbit.

OHB Sweden is the prime contractor for the delivery of the satellites for the EPS Sterna constellation. The consortium also includes Omnisys in Sweden as the supplier of the microwave instruments, which constitute the primary meteorological payload. A total of 20 satellites will be delivered under the contract. The industrial team includes approximately 30 companies. Germany is also strongly represented by SMEs that will contribute key hardware for the instrument and the satellite platform. The satellites will be procured by EUMETSAT through ESA. EUMETSAT itself will develop the ground segment, procure and provide the launch services, operate the satellites, manage the constellation and distribute the data through its data distribution mechanisms, which has a planned operational lifetime of 13 years.

This contract is another example of Europe’s fast shift in the past three years from the government model to the capitalism model. It took ESA almost a decade to finally decide to make that shift, but once it did it seems to be moving far faster than NASA did to implement it.

Why are commercial space startups shifting their focus to the military? $185 billion is the answer

9:21 am

War Department logo

In the past two years a number of space startups as well as established companies have shifted their work focus from getting NASA or commercial contracts to pursuing projects from the War Department.

The best example of this has been Sierra Space, which until three years ago was entirely focused on building a Dream Chaser reusable mini-shuttle to bring cargo to and from ISS, as well as partnering with Blue Origin to build their proposed Orbital Reef space station.

Then, in late 2023 the company underwent a major management and staffing shake-up aimed at winning military and national security contracts. At the same time work on its LIFE inflatable module — intended for Orbital Reef — practically ceased, while the effort to get Dream Chaser finished seemed to slow to a crawl, eventually causing NASA to drop it as an ISS cargo vehicle.

Sierra Space however is only one example. During this time Rocket Lab shifted its focus somewhat to the military in developing HASTE, its suborbital test version of its Electron rocket, in order to win substantial hypersonic test contracts from the Pentagon. And then there’s Tory Bruno, who quit his job as CEO of the rocket company ULA to take a job at Blue Origin heading a national security team aimed at winning that company military contracts.

So what has caused this shift? Has investment in the civil space industry dried up?

Hardly. The number of rocket startups continues to grow, fueled by the many new and established satellite companies planning constellations of tens of thousands to millions of satellites as well as the orbiting manufacturing possibilities presented by the five space stations under development. There is a lot of investment capital pouring into these efforts

The reason for this shift — which really isn’t so much a shift but a new focus that many companies are adding to their portfolio — is provided by an article today in Air & Space Forces Magazine, describing the War Department’s recent decision to add $10 billion to the budget of its Golden Dome project, raising it to $185 billion, while noting this:

Voyager-2’s only close-up image of Uranus’s moon Umbriel

12:38 pm

Uranus' five biggest moonsThe historically known moons of Uranus. Click for original NASA press release.

Umbriel as seen by Voyager-2
Click for source.

Today’s cool image continues our tour of the five largest moons of Uranus, as seen by Voyager-2 in 1986 during its close-up visit. The family portrait above, taken from more than three million miles away during Voyager-2’s approach, shows the relative sizes of those five moons as well as their location relative to Uranus, with Miranda in the closest orbit and Oberon the farthest. I have already posted close-ups from Miranda and Ariel. Today’s image moves us outward to Umbriel.

The image to the right is Voyager-2’s best picture. In fact, it is really Voyager-2’s only close-up image, and as you can see, it is not that close or sharp. I have not reduced it at all. This is how NASA released it. From the NASA press release:

The southern hemisphere of Umbriel displays heavy cratering in this Voyager 2 image, taken Jan. 24, 1986, from a distance of 346,000 miles. This frame, taken through the clear-filter of Voyager’s narrow-angle camera, is the most detailed image of Umbriel, with a resolution of about 6 miles.

Umbriel is the darkest of Uranus’ larger moons and the one that appears to have experienced the lowest level of geological activity. It has a diameter of about 750 miles and reflects only 16 percent of the light striking its surface; in the latter respect, Umbriel is similar to lunar highland areas. Umbriel is heavily cratered but lacks the numerous bright-ray craters seen on the other large Uranian satellites; this results in a relatively uniform surface albedo (reflectivity). The prominent crater on the terminator (upper right) is about 70 miles across and has a bright central peak.

The strangest feature in this image (at top) is a curious bright ring, the most reflective area seen on Umbriel. The ring is about 90 miles in diameter and lies near the satellite’s equator. The nature of the ring is not known, although it might be a frost deposit, perhaps associated with an impact crater. Spots against the black background are due to ‘noise’ in the data.

This lone picture of Umbriel by Voyager-2 illustrates even more starkly the very sparse data we have of Uranus and its moons. Voyager-2 is the only spacecraft to ever visit this planet, and it only did a quick fly-by, just long enough to give us this one dim snapshot view. It is forty years later, and no other missions have flown there, nor is any planned in the near future. There are proposals, but none are yet approved.

The first Artemis lunar landings might not go to the Moon’s south pole

10:09 am

It appears from remarks recently by one NASA official, that while the south pole remains the agency’s main lunar base target, it is now looking into other landing options in order to make those first manned landing less risky and easier and quicker to achieve.

Amit Kshatriya, NASA Associate Administrator was very vague in his statement, but nonetheless this was what it appears he was saying:

We have opened up the, I would say, the performance specification for the early landing missions in as many ways as we can, in terms of different lunar orbits we want to take, or different other constraints … to make it as agile as possible, to recognize performance limitations in some of the machines we have and let our providers tell us, hey, if you took these constraints out of the way, how could we go faster? So we’re going to do that.

The agency’s administrator, Jared Isaacman, is also pushing to quickly begin sending a lot of unmanned landers to the south pole by next year. Thus, under this plan, we might actually find out first whether there really is water in those permanently shadowed craters, before committing our manned lunar base to this location.

This new approach makes a great deal of sense, especially since the data that has looked into those craters has been very inconclusive, some positive and some negative.

Canada leases Nova Scotia spaceport for $200 million

9:55 am

Proposed Canadian spaceports
Proposed Canadian spaceports

The Canadian government yesterday announced it is committing significant funding to several space-related companies, including issuing a ten year $200 million lease to the Nova Scotia spaceport that has been unable to attract any launch customers for the past ten years.

The investment is a 10‑year, $200‑million agreement to lease a dedicated space‑launch pad that will serve as the central foundation for a multi-user spaceport near Canso, Nova Scotia. Operated by Maritime Launch Services, this spaceport will support the operational needs of the Department of National Defence (DND), the Canadian Armed Forces (CAF), and the wider Government of Canada, while also offering ad hoc access to allies and partners.

The history of Maritime and its Spaceport Nova Scotia is far from encouraging. It was first proposed in 2016, offering satellite companies both a launch site and a Ukrainian-built rocket. That plan fell through when Russia invaded the Ukraine and the rocket became unavailable. Since then Maritime has struggled to convince rocket companies to use the spaceport, all to no avail. It signed some deals, but none has gone anywhere. This Canadian government lease appears an attempt to save it, since it is very unlikely that this government will be capable of building its own rocket during those ten years.

In order to avoid accusations of favoritism, the government at the same time also announced further $8.3 million grants to three Canadian companies to help them develop their own rockets, one of which is Nordspace, which has its own proposed spaceport, the Atlantic Spaceport in Newfoundland. According to the government, these grants are part of a $105 million program to encourage a sovereign Canadian rocket industry. The other two companies are Reaction Dynamics, which wants to launch its suborbital rocket from Nova Scotia, and a new startup dubbed the Canada Rocket Company, of which little is known.

Apparently, the leftist Canadian government is following in the footsteps of the leftist government of the United Kingdom. In both cases their private spaceports have floundered for decades, unable to attract customers for a variety of reasons. To save them, both governments are now pouring cash into their pockets to prop them up.

In the case of the UK, the obstacles have almost entirely been the red tape of the government. In the case of Canada and Maritime’s Nova Scotia spaceport, it has been a series of bad management decisions that reflect poorly on the company. Private capital has thus not been interested in investing in it. Nor have any rocket companies been interested in launching from it.

So of course, the leftist Canadian government is going to use other people’s money to fund it. How typical.

Canadian may get its own launch capability from this program, but don’t bet on it. Government programs like this have routinely failed, wasting billions and decades with little to show for the effort. The program’s one saving grace however is that the government isn’t designing, building, and owning the rockets. It is instead hiring these three companies to do the work. Under that framework, there is a chance something might actually happen.

Terran Orbital wins contract to build cubesat to go to Apophis with ESA’s Ramses probe

9:08 am

Apophis' path past the Earth in 2029
A cartoon (not to scale) showing Apophis’s
path in 2029.

The satellite company Terran Orbital, owned by Lockheed Martin, has won a contract from the European Space Agency (ESA) to build a cubesat to fly with its Ramses probe that will launch in 2028 and rendezvous with the potentially dangerous asteroid Apophis when it makes its very close fly-by of the Earth on April 13, 2029.

The CubeSat is named after Italian scientist Paolo Farinella and is backed by the Italian Space Agency. After successfully completing the Critical Design Review in January 2026, Tyvak International [a subsidiary of Terran Orbital] will begin the implementation phase, with launch currently planned for 2028.

…Operating aboard the RAMSES spacecraft, developed by OHB Italia, the Farinella CubeSat will be one of two spacecraft deployed to explore the asteroid’s subsurface using low-frequency radar. The satellite will also carry Horus, an optical instrument that acts as both a science imager and navigation camera, and Vista, a dust detector previously flown on the Milani CubeSat from ESA’s Hera mission.

Apophis is estimated to be about 1,200 feet across. When it does its fly-by in ’29 it will get within 20,000 miles of the Earth, dipping within the orbits used by geosynchronous satellites. It will then pass within 60,000 miles of the Moon. At its closest it will for a short time be visible to the naked eye.

Apophis’ orbit means that it has the potential in the next century or so to impact the Earth. This particular fly-by is significant because the Earth/Moon’s gravity will change the asteroid’s path in an unpredictable manner that could either increase or decrease that impact possibility on future fly-bys. And we won’t know until after the fly-by is complete.

China completes two launches today

10:54 pm

China today completed two separate launches from two different interior spaceports. First it successfully placed a military “remote sensing” satellite into orbit, its Long March 6A rocket lifting off from its Taiyuan spaceport in north China.

Next it placed eight satellites into orbit using its Kuaizhou-11 solid-fueled rocket, lifting off from Jiuquan spaceport in northwest China.

China’s state-run press provided no further details on those eight satellites. It also did not provide any information about where the lower stages of both rockets crashed inside China. As the Long March 6A uses very toxic hypergolic fuels, that can dissolve your skin if you come in contact with it, this lack of information tells us a lot about China and its government.

The leaders in the 2026 launch race:

32 SpaceX
12 China
3 Rocket Lab
2 Russia

SpaceX continues to lead the entire world combined in total launches, as it did in both ’24 and ’25.

The new town of Starbase is canceling its May elections

12:15 pm

Boy, Elon Musk sure is a FASCIST! Because no one filed to run against the mayor and two commissioners, the new town of Starbase is now about to cancel its May elections.

During an upcoming meeting, the Starbase City Commission is scheduled to consider an ordinance canceling the May 2, 2026 General Election, as all candidates for mayor and city commissioner are running unopposed.

Under Texas law, local governments may cancel elections when every race on the ballot is uncontested.

That means Starbase’s current leadership will remain in office without voters needing to cast ballots. The city’s inaugural mayor is Robert “Bobby” Peden, a SpaceX executive who serves as Vice President of Texas Test and Launch for the company. Two commissioners serve alongside him: Jordan Buss, a senior director of environmental health and safety at SpaceX, and Lois Wallace, an interim commissioner and Starbase resident.

Expect to see stupid mainstream stories suggesting no one filed because people were afraid to run against these SpaceX managers and thus threaten their job status. “Musk, that evil fascist, clearly threatened to send out hit men against anyone who filed! Opposition to Musk will not be allowed!”

What I think is really happening is twofold. First, no one at SpaceX is really interested in this boring administrative government work. They’d rather build cutting-edge rockets. Note that the two commissioners are not really rocket engineers, with one being the wife of a SpaceX employee and the other doing “environmental health and safety” work, likely related to making sure SpaceX meets government work regulations. The real engineers at SpaceX have better things to do.

Second, there really isn’t that much for these town officials to do anyway. The town was established mostly to ease SpaceX’s own regulatory red tape with the state, and once established the task is largely done. Why waste time running for a position that will only add to your work load, while accomplishing nothing of real substance?

A day-by-day description of the entire Artemis-2 manned mission

10:04 am

NASA today posted a detailed day-by-day description of the entire ten-day Artemis-2 manned mission around the Moon, outlining the tasks planned for the astronauts on each day.

The launch is now targeting April 1, 2026.

The description of their closest approach to the Moon is both interesting and underwhelming.

The Artemis II crew will come their closest to the Moon on flight day 6, while traveling the farthest from Earth. Artemis II could set a record for the farthest anyone has traveled from Earth depending on launch day, breaking the current record – 248,655 miles away – set in 1970 by the Apollo 13 crew. The distance the Artemis II crew will travel depends on their exact launch day and time.

Over the course of the day, the crew will come within 4,000 to 6,000 miles of the lunar surface as they swing around the far side of the Moon – it should look to them about the size of a basketball held at arm’s length. [emphasis mine]

In other words, Orion is not going to get very close, and in fact, the Moon will only be 2 to 3 times bigger than what we see here on Earth. I suspect the best photographs taken will be those showing both the Earth and Moon, both of which will be relatively small.

Overall, I remain highly concerned about this mission. The life support system has never been tested in space before, and they will spend the first day checking it out in Earth orbit. And the return to Earth will involve using a heat shield that did not perform well on the Artemis-1 mission in 2022, losing chunks during re-entry.

They hope a less stressful flight path will mitigate this issue, but then, they need to hit that flight path perfectly on their way back from the Moon. During yesterday’s briefing it was obvious this was a concern to NASA officials.

China to begin construction of its Mars sample return spacecraft

8:13 am

China’s state-run press today announced it is about to begin construction of its Mars sample return spacecraft, Tianwen-3, set for launch in 2028.

Based on the announcement, that date seems very unlikely.

China’s mission to retrieve samples from Mars will advance to the flight model development phase within this year, Liu Jizhong, chief designer of the Tianwen-3 mission, said on Thursday. Building on the preliminary technical research and demonstrations, the mission has achieved breakthroughs in key technologies. The engineering team is now focused on developing prototypes, Liu, also a national legislator, told reporters.

The Mars sample return mission is scheduled for launch around 2028, with the goal of returning no less than 500 grams of Martian samples to Earth by around 2031. [emphasis mine]

They only have two years to get the spacecraft built, and it involves “an orbiter, a returner, a lander, an ascender, and a service module.” While China is basing this mission’s design on its successful Chang’e lunar sample return missions, returning samples from Mars is significantly more challenging. The ascent vehicle will have a much greater gravity to overcome, and doing a robotic rendezvous and docking in orbit around another planet millions of miles from Earth has never even been tried.

China completes two launches early today

7:40 am

China early today resumed launches after a month-long pause, apparently for the Chinese New Year.

First, it completed the 20th launch for the Guowang (Satnet) internet satellite constellation, its Long March 8A rocket lifting off from its coastal Wencheng spaceport.

Though China’s state-run press provided no information on the number of satellites in the payload, all previous launches using the Long March 8A had carried nine satellites. If so, that would mean the constellation now has 159 satellites in orbit, out of a planned 13,000.

Next, China placed two “test satellites” into orbit, its Long March 2D rocket lifting off from its Xichang spaceport in southwest China. Its state-run press provided no information about where the rocket’s lower stages, using very toxic hypergolic fuels, crashed inside China.

The leaders in the 2026 launch race:

30 SpaceX
10 China
3 Rocket Lab
2 Russia

SpaceX continues to lead the entire world combined in total launches, as it did in both ’24 and ’25. Though it has up to now almost doubled the launch pace of everyone else, with China resuming launches that pace will likely end.

Cubesat ultraviolet space telescope achieves first light

5:05 pm

Sparcs first light images
Click for original images.

A new low-cost cubesat-sized NASA ultraviolet space telescope, dubbed Sparcs, has achieved first light, successfully taking both near- and far-ultraviolet false-color images of a nearby star.

Those images are to the right, with the top the far-ultraviolet image and the bottom in the near ultraviolet. From the press release:

Roughly the size of a large cereal box, SPARCS will monitor flares and sunspot activity on low-mass stars — objects only 30% to 70% the mass of the Sun. These stars are among the most common in the Milky Way and host the majority of the galaxy’s roughly 50 billion habitable-zone terrestrial planets, which are rocky worlds close enough to their stars for temperatures that could allow liquid water and potentially support life.

The question astronomers will try to answer with this telescope is whether the solar activity on these stars is high enough to prevent life from forming in the star’s habitable zone. Because these stars are dim and small, the habitable zone is quite close to the star, which means solar activity has a higher impact on the planet. We don’t yet have sufficient data to determine the normal activity of such stars. Sparcs will provide a good first survey.

It will also demonstrate the viability of such small low-cost cubesats for this kind of research. If successful expect more such telescopes, some of which are likely to be private, like Blue Skies Space’s Mauve optical telescope already in orbit.

NASA now targeting an April 1st launch of Artemis-2

3:54 pm

At a press briefing today, NASA officials said they are now targeting an April 1, 2026 launch date for the Artemis-2 mission, a ten-day manned mission sending four astronauts around the Moon.

NASA completed the agency’s Artemis II Flight Readiness Review on Thursday, March 12, and polled “go” to proceed toward launch. NASA is targeting Thursday, March 19, to roll the SLS (Space Launch System) rocket and Orion spacecraft to launch pad 39B in advance of a launch attempt Wednesday, April 1, pending close out of remaining open work.

The repair work involved replacing a helium seal that was preventing flow to and from the tanks and testing it to confirm the new seal worked. It also involved replacing batteries as well as some oxygen seals.

NASA officials also stated that they do not plan to do another wet dress rehearsal, that they are satisfied by the testing they did in the assembly building. Instead, they are go for full launch countdown, with the hope they can lift-off with no more fueling issues. They have also determined that if there is a scrub, they will also have several launch opportunities through April 6th.

To underline the risks of this mission, the Orion capsule in which they are sending four astronauts around the Moon has an uncertain heat shield and an untested life support system. To mitigate the shield uncertainties, they must hit a specific flight path through the atmosphere upon return.

Real change at the FCC?

1:51 pm

Brendan Carr during Breitbart interview
Brendan Carr during Breitbart interview

FCC chairman Brendan Carr this week didn’t simply make a public statement yesterday against Amazon, as I reported earlier today. The day earlier, on March 10th, he did an hour-long interview with Breibart News, providing a more complete summary of the FCC’s overall agenda since the change of administrations from Joe Biden to Donald Trump.

You can watch that interview here. To put it mildly, the shift in policy and approach at the FCC is significant, and appears to be generally moving in the right direction.

To understand the context, we need to first review the FCC’s approach during the Biden administration. My regular readers will remember the many stories during that time describing the FCC’s aggressive effort to expand its regulatory power, in many cases in areas completely exceeding its fundamental statutory authority. For example, it proposed new regulations designed to tell satellite companies how and when to de-orbit their satellites. It also wanted to its own bureaucracy for imposing those regulations, and went ahead and created it without any congressional approval. It also under Biden attempted to limit satellite operations that the astronomy community opposed, an action that was once again outside its statute authority.

Overall, the goal of the FCC under Biden was to expand the power of the administrative state, in as many areas as possible. And though there was push back from Congress, as long as a Democrat was president it was clear that this power-grab was going to grow exponentially.

After the 2024 election, however a Democrat was no longer president. Trump quickly moved in 2025 to squash the FCC’s power grab, with a stated public goal to instead streamline FCC regulations and speed license approvals.

Carr’s interview earlier this week essentially gave us an update on that Trump policy, and it appears this new anti-regulatory policy is moving forward, with a goal to eliminate ten regulations for every one regulation added. According to Carr:

China’s giant Spacesail constellation seeks more funding

9:57 am

Spacesail, one of the largest of China’s planned constellations designed to compete with Starlink, is now seeking more funding to build its full constellation of 10,000 to 14,000 satellites.

Shanghai Spacecom Satellite Technology, or SpaceSail, a satellite communications company developing a massive constellation known as “Qianfan,” disclosed plans to bring in new investors through a capital increase, according to a notice published on the Shanghai United Assets and Equity Exchange.

At present, this Chinese pseudo-company has launched only 119 out of the constellation’s first phase of 648 satellites. While it has gotten Airbus to sign a contract to use its constellation on its airplanes, it also appears to be somewhat cash poor, having only about $150 million on hand (much of it government funding), and is not going to meet its international licensing requirement to get those 648 satellites in orbit by the end of this year.

This new funding round announcement suggests it is in need of capital, and is having trouble getting the Chinese government to cough up the additional funds.

FCC chairman blasts Amazon and its Leo satellite constellation

9:08 am

FCC logo

Brendan Carr, the chairman of the Federal Communications Commission, yesterday harshly criticized Amazon for filing papers opposing SpaceX’s application to place a million new satellites into orbit while failing to meet its own FCC license requirement to get 1,600 Amazon Leo satellites in orbit by July 2026.

Amazon should focus on the fact that it will fall roughly 1,000 satellites short of meeting its upcoming deployment milestone, rather than spending their time and resources filing petitions against companies that are putting thousands of satellites in orbit.

To put it mildly, Carr’s point is well taken. In legally protesting SpaceX’s proposed constellation while failing to launch on time as promised, Amazon is following what appears to be standard Jeff Bezos’ practice, epitomized by his rocket company Blue Origin. When customers begin favoring others because the Bezos company either submits a poor bid or fails to meet schedules, the Bezos companies routinely go to court in an attempt to squelch that better competition.

Carr is demanding Amazon stop this, and focus instead on getting its own job done for once. Carr is also signaling the FCC’s position on both SpaceX and Amazon. It is likely going to reject Amazon’s filing and give its okay to SpaceX’s million-satellite constellation, in one form or another.

Carr is also telling Amazon that it faces some push back for failing to launch the required number of Amazon Leo satellites on time. Though it is extremely unlikely the FCC will cancel Amazon’s Leo license, the FCC might fine it heavily. Or it could impose new limits on the constellation. Carr is also indicating the FCC will treat future Amazon license applications much more stringently.

NASA’s Van Allen Probe A burns up over the Pacific

8:49 am

We didn’t all die! Van Allen Probe A, one of two NASA spacecraft launched in 2012 to study the Van Allen radiation belts that circle the Earth, yesterday burned up harmlessly over the Pacific ocean as expected.

Both Van Allen probes have been defunct since around 2019, when they ran out of fuel. Van Allen Probe B weighed about 1,300 pounds, so some pieces probably reached the ocean. Had it returned over land it did carry the small risk of doing harm.

The orbit of the other probe, Van Allen Probe B, is expected to decay sometime around 2030. Like its twin, it is heavy enough that some parts will survive re-entry. It is therefore a prime target for a demonstration mission proving the technology for removing space junk safely and under control. NASA should put out a request for bids to the many orbital tug companies that now exist to do exactly that, as it is NASA’s responsibility to make sure this spacecraft re-enters the atmosphere safely.

Chinese scientists pinpoint a prime landing site for its manned lunar mission

9:21 am

Potential landing site for China's manned lunar landing

Though no final decision has apparently been made, a just published research paper suggests that China is considering a location almost dead center on the Moon’s near side, on the edge of a mare region dubbed Sinus Aestruum, for its first manned lunar landing, presently targeting a 2030 launch date. From the abstract:

We propose four prospective landing sites in the traversable areas, which provide a range of diverse geological samples, including volcanic debris, mare basalts, Copernicus crater ejecta and high-Th materials. Such a collection may provide insights into the geological evolution of the region and enhance our understanding of the lunar mantle composition and volcanic processes.

The red star on global lunar map to the right, taken from figure 1 of the paper, shows the location of this region. The lower map zooms into the region, with the four stars indicating the four prospective landing sites. The region has several rilles, long meandering channels thought to have formed from lava flow, that could be reached during an EVA.

Though it appears the scientists of this paper are lobbying for this landing region and no final decision has been reached, its location and wide variety of geology strongly suggests this will be the final choice. If so, of the four landing sites outlined two are in the smoother mare regions, and two are off the edge, in rougher terrain. For safety considerations, it is likely the final landing site will be in one of the former.

Voyager to make “a multi-million-dollar strategic investment” in Max Space’s inflatable habitats

3:16 pm

Voyager-Max lunar habitat
Click for original image.

In an expansion of a partnership announced last month, Voyager Technologies — the lead company in the consortium building the Starlab space station — today announced it is now making “a multi-million-dollar strategic investment” in Max Space’s inflatable habitats, aiming at winning contracts both for NASA’s proposed Moon base as well as any other “future deep space missions.”

The actual dollar amount has not yet been released, but my sources say it is in “the low eight figures,” or more than $10 million but probably less than $25 million.

This partnership appears aimed not at NASA’s space station program nor enhancing Starlab. Instead, it is focused on providing NASA (and other commercial operations) inflatable habitats that can be launched and quickly established on the Moon and elsewhere, as shown by the artist’s rendering to the right. It appears Voyager will build the foundation, base, and airlock, while Max will provide the inflatable module above. From the press release:

This initiative directly supports NASA’s historical Artemis Program and aligns precisely with Administrator Isaacman’s announcement to be on the Moon to stay by 2028. Max Space delivers critical enabling infrastructure, maximizing livable volume, enhancing crew safety, and reducing the cost and complexity of surface deployment. It complements Voyager’s broader lunar roadmap, including cislunar mission management, surface logistics, propulsion, power systems, and future surface infrastructure, reinforcing a shared vision of the Moon as an operational domain, not a temporary destination.

In other words, the two companies are aiming to become major suppliers for NASA’s Artemis lunar base, and to do that by offering a way to get it quickly built and operational, at a reasonable cost.

I suspect it will be a few years before NASA issues any such contracts. It will first want to see both companies demonstrate success, both with Voyager’s Starlab and Max Space’s own demo station module scheduled for launch in ’27. Nonetheless, this announcement puts them on the map in the race to get those contracts, and begins to put some commercial reality to the American colonization of the solar system.

Italian rocket company Avio wins $65 million War department contract

9:25 am

The Italian rocket company Avio announced last week that it has won a $65 million contract to build a solid-fueled motor for the U.S. Department of War.

Defense Systems and Solutions (DSS), a joint venture between Yulista Integrated Solutions, LLC (YIS) and Science and Engineering Services, LLC (SES), acting as a prime contractor for the US Department of War, selects Avio Group for the development, qualification and initial production of a solid rocket motor for air defense applications.

The contract, amounting approximately to $65 million and covering a three-year period, paves the way for a broader cooperation between the Parties, to exploit respective competences to provide US Government and NATO Allies with critical Defense Systems.

This contract award is significant in several ways. First, it signals the success of Avio’s policy in the past two years to establish itself as a U.S. military contractor, despite being a long-time Italian company. To do this it created a U.S. division, begun construction of a U.S-based manufacturing facility, and committed $500 million to its construction.

Second, Avio’s quick success also illustrates a general weakness in the American solid-rocket industry. It appears the American company that previously dominated this field of military solid-fueled rockets is Northrop Grumman, and its work in recent years has been problematic. Others might also do this work, but it appears no U.S. company has been doing it well enough to satisfy the War Department. The result has been an opportunity for Avio, and it appears it is taking advantage of it.

Finally, this success proves the rightness of the capitalism model. For almost two decades Avio built solid-fueled rockets for the European Space Agency’s commercial division, Arianespace, which controlled the marketing and sale of the rockets. That government control not only created a government middle-man that eat into the profits, it discouraged competition and innovation. Last year ESA completed transfer back to Avio, and the result has been new contracts from many new sources for the company.

The Senate cries “Uncle!” on SLS and big goverment with its latest NASA authorization bill

8:01 am

I usually pay relatively little attention to the NASA authorization bills that Congress passes periodically, because these bills are generally nothing more than opportunities for the loudmouths in Congress to use them as a bullhorn to puff themselves up to the public and press. Almost never do such bills really have any real impact on the future, or if they do, that impact is often unintended and negative, as Congress is by and large ignorant about these matters and has priorities counter-productive to getting anything substantive accomplished.

I pay even less attention to authorization bills that have only been approved by a committee, and have not yet been voted on by either house. Such bills are ephemeral and the stuff of fantasy. It is nice to know what’s in them, but until such bills are actually approved by both houses of Congress and signed by the president, their language is even more unworthy of serious attention.

Have the pigs in the Senate learned to stop gorging themselves?
Have the pigs in the Senate learned to stop gorging themselves?

Nonetheless, the NASA authorization bill that was just approved by the Senate Commerce committee is worth reviewing, but not for the reasons that has interested the rest of the mainstream and even the aerospace press.

True, the bill extends ISS until 2032. True, it fully supports the commercial private space stations being built to replace it. True, it endorses NASA administrator Jared Isaacman’s restructuring of the Artemis program. True, it rejects all of Trump’s proposed cuts to NASA’s science programs. And true, it strongly endorses a Moon base as a first step to colonizing Mars.

All of these facts are significant, but to focus on each specifically — as it appears the entire press has done — is to miss the forest for the trees.

NASA awards ULA’s Centaur-5 upper stage for future SLS launches

4:30 pm

NASA yesterday awarded ULA the contract for providing SLS its upper stage after the Artemis-3 mission using the Centaur-5 upper stage that was developed for the company’s Vulcan rocket.

In its procurement statement, NASA said its intention is to issue a sole source contract to ULA, meaning it’s the only upper stage being considered for this new iteration of the SLS rocket. An eight-page supporting document from NASA’s Marshall Space Flight Center (MSFC) in Huntsville, Alabama, was published to document the reasoning for its decision.

Among the stated reasons are the decades-long heritage of the RL10 engine, which has matured over time; the ability of the Centaur 5 to use the interfaces available on the Mobile Launcher 1 (ML1) along with the propulsion commodities of liquid oxygen and liquid hydrogen; and the experience of ULA’s teams working with NASA’s Exploration Ground Systems (EGS) at the Kennedy Space Center and elsewhere in the country.

They also noted that with the Centaur 3 upper stage achieving certification to launch humans as part of the Commercial Crew Program, there are a lot of common features with the Centaur 5.

The decision relieves NASA from wasting more money on the Mobile Launcher-2, which has been a disaster. The contractor Bechtel has gone over budget — from $383 million to $2.7 billion — and is so behind schedule it is still unclear now whether it will be ready by 2029, a decade after the contract was awarded.

It also relieves NASA of spending more money on its own upper stage, which has been as much a disaster, from Boeing.

Instead, this deal is an example of Isaacman doing the right thing. Rather than have NASA design and build its own upper stage, he is buying the product — almost literally off-the-shelf — from a commercial rocket company. He should expand this effort, and consider other private rockets, such as Falcon Heavy, to replace SLS itself.

Now Isaacman should consider suing Bechtel for fraud and incompetence, to try to get back some of the money it wasted.

South Korean rocket startup Perigee signs deal to launch from the Philippines

10:03 am

The Philippines

The South Korean rocket startup Perigee yesterday signed an agreement with the government of the Philippines, allowing it to launch its proposed suborbital and orbital Blue Whale rockets from a sea platform within that country’s territorial waters.

The Philippine Space Agency (PhilSA), together with the Department of Information and Communications Technology (DICT), Cagayan Economic Zone Authority (CEZA), Ascend International Gateway, Inc., and … Perigee Aerospace, Inc. signed a Memorandum of Understanding … to collaborate on a framework for rocket development training and experimental rocket launches in the Philippines. These initiatives will demonstrate the viability of the establishment and operation of a Philippine spaceport, with the goal of positioning the country as a gateway to space in the region.

…The agreement builds on the rocket technology know-how transfer and training program undertaken by PhilSA engineers in the Republic of Korea from October to November 2025, in collaboration with Perigee Aerospace. The program equipped the engineers with foundational and applied knowledge in launch vehicle systems through lectures and hands-on experience in rocket assembly and testing. These initiatives lay the groundwork for future activities, including possible localized assembly, testing, and launch operations in the Philippines.

The first four entities listed above are all government agencies in the Philippines. Apparently Perigee is providing training and aid to the Philippines in exchange for the right to launch from within that country. It website states the suborbital version of Blue Whale will launch from a sea platform, but the launch site for the orbital version is unclear.

This deal however sets the stage for possibly developing a land-based spaceport in the Philippines. As shown by the map to the right, the country is well situated for such purposes, with a lot of eastern coastline facing the vast Pacific ocean. A spaceport located on its southernmost island of Mindanao would be especially well placed.

ESA loses contact with the coronagraph satellite of its duel-satellite Proba-3 mission

9:24 am

The Proba-3 mission

The European Space Agency (ESA) today announced that engineers have lost contact with the Coronagraph satellite of its duel-satellite Proba-3 mission, and are working now to recover contact.

During the weekend of 14–15 February 2026, an anomaly onboard Proba-3’s Coronagraph spacecraft triggered a chain reaction that led to the progressive loss of attitude (spacecraft orientation) and prevented the entry into safe mode.

Because the spacecraft’s solar panel was no longer facing the Sun, the onboard battery started to discharge quickly. This caused the spacecraft to enter survival mode, when minimum electronics are active and data transmission to the ground is interrupted.

The exact root cause of the anomaly is under investigation, and mission teams and operators have joined forces to attempt to re-establish contact with the spacecraft to recover the situation.

The Coronograph satellite is the heart of this mission. It records the data, available because the Occulter blocks the Sun from view so that the corona, the Sun’s atmosphere, can be seen. Based on this report, it does not look good that the spacecraft can be recovered.

At the same time, the mission has apparently achieved all of its initial goals, and was now on an extended mission.

Sierra Space raises $550 million in private investment capital

9:01 am

Due to its aggressive shift in the past year away from NASA-based civilian contracts to defense work, Sierra Space announced yesterday that it has successfully raised another $550 million in private investment capital.

That shift occurred because of its failure to deliver its Dream Chaser vehicle to NASA as planned, as well as the apparently lack of progress in its partnership with Blue Origin on the Orbital Reef space station. From the press release:

Sierra Space Corporation, an industry-leading defense-tech space company delivering solutions for the nation’s critical missions, announced today a $550 million equity investment led by LuminArx Capital Management (“LuminArx Capital”), a global alternative investment manager, with participation from existing investors. The financing values the company at $8 billion post-money.

With this new capital, Sierra Space will be able to further focus on its national security space efforts through ongoing expansion of production capacity and continued development of differentiated solutions for its customers. The investment better positions Sierra Space to secure additional contracts, leverage existing technologies, and pursue growth opportunities beyond its current satellite and spacecraft mission programs.

The release also mentioned General Atlantic, Coatue, Moore Strategic Ventures, and Andalusian Private Capital as investors.

Though this money should help fuel its work on Dream Chaser and Orbital Reef, I suspect little will go to those two projects. The company is now clearly targeting military and national security work as its prime source of income. There are also indications that there are some technical issues with Dream Chaser that Sierra has not yet revealed.

Meanwhile, the lack of effort from Blue Origin on Orbital Reef likely convinced Sierra it was better to turn its eyes elsewhere. While Sierra spent considerable effort testing its LIFE inflatable module, Blue Origin did practically nothing, and continues to do little. It is unlikely this partnership will win any funding from NASA when the agency awards new space station contracts, expected sometime in six months.
