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 Proba-3 mission. Click for original.

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.

The United Kingdom’s Labor government to spend £500 million on space

10:07 am

The UK Space Agency, gone but not forgotten
The UK Space Agency, gone but not forgotten

My heart be still! The United Kingdom’s present Labor government yesterday announced it has allocated an additional £500 million ($665 million) on a wide range of space projects, all of which are either new government programs or facilities or direct subsidies to its failing space businesses.

Nowhere in this announcement did government officials address the choking regulations and burdensome licensing requirements that have essentially driven away all space business while bankrupting two different rocket startups, Virgin Orbit and Orbex.

In addition to the £1.7 billion committed to European Space Agency (ESA) programmes in November 2025, the government is allocating more than £500 million to national space programmes:

  • £105 million to develop civil capabilities for in-orbit servicing and manufacturing (ISAM) – an emerging market where the UK has a strong competitive edge and opportunities to deliver significant commercial returns and strengthen national resilience
  • £85 million to develop the National Space Operations Centre, including £40 million to build a new ground‑based sensing network, supporting the 24/7 requirement to protect satellites and manage an increasingly crowded space environment
  • £80 million to deliver the Connectivity in Low Earth Orbit (C-LEO) programme, including for a new £30m funding call opened today to support UK businesses developing smarter satellites, advanced hardware and AI‑enabled data delivery
  • £65 million for the National Space Innovation Programme to accelerate breakthrough technologies and boost commercialisation
  • £40 million for the Unlocking Space Programme to drive market demand for space technology, develop national security capabilities and attract private investment to support the scale up of UK firms
  • £37 million to develop space clusters, building on local strengths and ensuring the benefits of space reach every corner of the UK
  • £20 million to accelerate spaceport infrastructure development in Scotland

The announcement was made in connection with the decision by this Labor government to eliminate the UK Space Agency as a separate bureaucracy, consolidating it into the Department for Science, Innovation and Technology (DSIT). The consolidation was intended to save money and make the government more efficient, but this announcement suggests it is being used to funnel more cash into DSIT’s bureaucracy, simply under a different name.

None of this is going to do much to promote an independent space industry in Great Britain. As long as it continues to take years to get launch licenses, rocket companies are not going to launch from its spaceports. And without those launches, its space industry is going to be seriously handicapped. And dumping cash into these various government programs won’t do much either to promote competition or innovation. All the UK will get is more bureaucracy and government control.

NASA initiates new program to grab talent from the private sector

4:00 pm

Where new talent will now go to wither
Where new talent will now go to wither.

As part of NASA administrator’s effort to remake NASA into a cutting edge agency, “the global leader in space,” the agency in partnership with the federal Office of Personnel Management (OPM) has initiated a new program, dubbed NASA Force, to recruit talent from the private sector for two-year terms, after which they can then try to get a full time job either with NASA or a private aerospace company.

NASA Force will identify and place high-impact technical talent into mission-critical roles supporting NASA’s exploration, research, and advanced technology priorities, ensuring the agency has the cutting-edge expertise needed to maintain U.S. leadership in space.

Tech Force, led by OPM, was established to recruit elite technical professionals into federal service, embed them at partner agencies to modernize systems, accelerate innovation, and strengthen mission delivery. NASA Force represents a focused expansion of that effort, tailored to the unique technical demands of space exploration and aerospace research.

“America’s leadership in space depends on extraordinary talent,” said NASA Administrator Jared Isaacman. “NASA Force will help us attract the next generation of innovators and technical experts who are ready to solve the toughest challenges in exploration, science, and aerospace technology. This partnership strengthens our workforce and helps ensure the United States remains the global leader in space.”

This program however has things entirely backwards. The last thing any engineer who has just graduated college should do is get a short two-year job at NASA. He or she will learn all the wrong lessons, working for a government agency not interested in efficiency or profit.

Instead, it is essential the first job new engineers get is in the private sector, to learn how to do things fast and efficiently. It Isaacman had the right priorities, he would use this money to fund these jobs in the private sector, so that new graduates will get the right training. Unfortunately, that is not Isaacman’s priority. He wants the government to lead.

Moreover, NASA’s job was never intended to be “the global leader in space.” Its job was to formulate the federal government’s needs in space, and then ask the private sector — the American people — to get the job done. Isaacman instead wants to have NASA do the job, as it did for a half century after Apollo, quite poorly. Only after the agency began relying on private enterprise beginning in 2008, the capitalism model, did things finally start happening again.

The worst aspect of this program is that it will take talent away from the private sector. A lot of good and talented young engineers will gravitate to these NASA positions for the high pay, relatively easy good hours, and prestige. They won’t accomplish much there, and their training will be wrong-headed. Meanwhile, the private sector will lose that talent and have to find it elsewhere, assuming it is available at all.

ESA asks for proposals on building its own space station

9:33 am

ESA logo

The European Space Agency (ESA) last week issued an open call for proposals outlining the construction of its own space station, independent of the five American stations presently in development to replace ISS.

On 27 February, ESA published an intended call for tenders for two Pre-Phase A studies under Scenario 3. According to the call, the studies will consolidate the “feasibility, architecture, utilisation, and technology requirements of a European-led LEO outpost” and propose cooperation with the Canadian Space Agency, Japan’s national space agency JAXA, and “additional partners.” The results of the two parallel studies will be used to enable ESA decision-making for its post-ISS transition by the end of 2026.

Do not expect these “studies” to produce a European-led space station any time soon. It is the ESA way to do lots of studies, and then after reading these to do more detailed follow-up studies outlining what they will do. Then, after years of review, it might finally get started on construction, which always proceeds somewhat slowly.

In the meantime, ESA has signed agreements with three of the five American space station projects (Axiom, Starlab, Vast), with its deal with the Starlab station the most extensive. All three deals leave open the possibility that Europe will rent time at each station to fly experiments and astronauts there.

Engineers locate helium flow issue on SLS upper stage

8:01 am

NASA last evening posted an update on the status of its SLS rocket, noting that engineers had located the seal that had caused the helium flow issue in the upper stage during unfueling after the wet dress rehearsal two weeks ago.

Engineers determined a seal in the quick disconnect, through which helium flows from the ground systems to the rocket, was obstructing the pathway. The team removed the quick disconnect, reassembled the system, and began validating the repairs to the upper stage by running a reduced flow rate of helium through the mechanism to ensure the issue was resolved. Engineers are assessing what allowed the seal to become dislodged to prevent the issue from recurring.

Though this information is somewhat vague, it strongly suggests the seal with the problem was in the upper stage, not the umbilical line that is part of the ground systems.

Before they can return the rocket to the launchpad, they need to make sure they identified the exact issue that caused the seal to not work properly. They also are replacing the batteries in the rocket’s self-destruct system as well as flight batteries in the upper stage, core stage, and two strap-on solid-fueled boosters. It also appears they are replacing another seal the oxygen feed line for the core stage.

Once this work is finished and confirmed, they will still need to roll SLS back to the launchpad and likely do another wet dress rehearsal countdown, though that rehearsal might be condensed to focus on these issues specifically.

The present launch window closes on April 6th, so the timeline is very tight. NASA management is reviewing later windows in late April as well as May and June.

Despite the major reshaping of the later missions in the Artemis program that NASA administrator Jared Isaacman announced last week, this upcoming Artemis-2 mission remains the same, a ten-mission carrying four astronauts around the Moon using an Orion capsule with a questionable heat shield and an untested life support system.

While Democrats rage against the American/Israel war on Iran, the PEOPLE celebrate

11:05 am

Without doubt there remain great risks and real constitutional issues involved the present military campaign by both the United States and Israel to destroy the Islamic leadership in Iran. First, it is almost impossible to force a change in power solely by air power. This has been tried numerous times, with little success. Killing the leaders of this terrorist Iranian government is a positive step, but it remains entirely unclear whether this war can produce a better government there.

Second, as much as there might be legal precedents that allow President Trump to initiate this action without direct congressional approval, it continues a dangerous trend ceding power away from Congress and to the presidency, in direct opposition to the intentions of the Founding Fathers in their writing of the Constitution. They very much were opposed to giving any president the power to start a war unilaterally.

Pro-U.S. and Israeli demonstrations by Iranians
Click here and here for original videos.

Having stated the reasonable objections to this military action, however, we must now take a look at the two images to the right to see its immediate and very positive consequences. Both pictures are from videos of very spontaneous demonstrations on February 28, 2026 by Iranian refugees celebrating the American/Israeli attacks against Iran.

The top picture is a screen capture from a demonstration in Georgetown, DC. The bottom picture is a screen capture from a demonstration in Austin, Texas.

Note the flags in both pictures. There are numerous flags of Iran (the version during the Shah’s rule, not the version from the Islamic Revolution). There are many American flags, of course, since these demonstrations are in America.

What is most revealing however are the Israeli flags, being enthusiastically waved by Iranians. Clearly the decades of hate against Israel and Jews by the mullahs in Iran has not had any impact on these Iranian refugees. In fact, in the video of the bottom picture they are chanting “Thank you, Bibi!”, referring to Israel’s leader Benjamin Netanyahu as the camera pans across the crowd.

Moreover, these demonstrations took place in two Democratic Party strongholds, cities where pro-Hamas demonstrations have been routine, including rioting and violence against Jews and anyone who dared suggest Israel’s actions in Gaza might be justified.

Nor are these two demonstrations an exception. They have been the rule across the United States and Europe, as well as in Iran itself. The public — the ordinary people for whom governments are meant to serve — seem very much in favor of what President Trump and Netanyahu are doing in Iran. And they are expressing that support of both America and Israel quite unequivocally. If this doesn’t indicate to the world that Israel and the rest of the Middle East can live together in peace and mutual cooperation, nothing can.

This conclusion is further supported by the response by almost every Arab nation in the Middle East, most of whom started off quite willing to let the U.S. and Israel do this deed, with no opposition or with covert support. Now, because of Iran’s indiscriminate attacks on Arab nations, they have all publicly joined the war, allying themselves not with the Islamic nation of Iran but with the U.S. and Israel.

I would not be surprised if Saudi Arabia soon signs the Abraham Accords. Nor would I be surprised if most of the last remaining Arab nations that have not yet done so join Saudi Arabia.

We could very well be seeing a major realignment of alliances in the Middle East that could really really harbinger the beginnings of real peace in that region. Imagine: Israel at peace with all its neighbors, because the Arabs have finally recognized that it is to their own best interest to do so as well.

Japan to do vertical tests of its own Grasshopper-type demo stage this month

9:13 am

Japan’s space agency is about to attempt two test vertical take-off-and-landing test flights of of its own Grasshopper-type demo stage, dubbed RV-X later this month.

First flight of a small experimental version of a reusable launch vehicle has been scheduled for March 6 by the Japan Aerospace Exploration Agency (JAXA). The 24-ft.-tall vertical-takeoff-and-vertical-landing (VTVL) RV-X is planned to make a short hop at the agency’s Noshiro Rocket Testing Center on the Sea of Japan coast.

RV-X is the first of two flight experiments planned by JAXA on the path to development of a reusable first stage for a next-generation launch vehicle. A second vehicle is planned to fly in 2027 under the multinational Callisto program.

Callisto is being developed jointly with the European Space Agency. Both it and RV-X have been in development for about a decade. Both were initiated in response to SpaceX’s successful reuse of its Falcon 9 first stage. Both projects however appeared stalled until the last two years or so, with little happening.

The JAXA engine on RV-X is apparently the engine it is providing for Callisto. If the flight tests are successful this March, it will be the be transferred to French Guiana for Callisto tests planned no sooner than ’27.

Russia completes repairs to Soyuz-2 launchpad at Baikonur

8:47 am

According to Roscosmos, it has completed the repairs to Soyuz-2 launchpad at Baikonur, and will do launch a Progress freighter to ISS on March 22, 2026.

According to the State Corporation, a total of 150 workers from four contractor organizations prepared and painted 2,350 square meters of structures, replaced all the attachment devices, replaced and tuned up electric equipment and inspected or serviced all the systems and mechanisms of the service platform. The team also made 250 welding lines.

The most complex task was the installation of the platform elements, some of which had a length of 19 meters and mass of 17 tons, which required a development of special methodic, Roskosmos said.

The State Corporation confirmed that the first mission departing from the repaired launch pad at Site 31 was scheduled for March 22, 2026, carrying the Progress MS-33 cargo ship to the ISS.

For Russia, this repair was completed remarkably fast. But then, the Russians generally get things done fast when it is absolutely essential to do so. Without that pad, Russia had no way to launch any astronauts in space. Nor could it send supplies to ISS. A delay would have been very public and embarrassing.

If there is no immediate need, however, its projects drag on endlessly.

Sunspot update: Sunspot activity tumbles in February, including the 1st blank days since ’22

10:53 am

The uncertainty of science! It is the start of the month, and thus time for another sunspot update, using NOAA’s monthly graph of the sunspot activity on the Earth-facing hemisphere, updated by NOAA to include the activity in February but annotated with extra information by me to illustrate the larger scientific context.

Last month I lambasted NOAA’s solar science panel for its consistently failed predictions, and made a tentative prediction of my own, suggesting the ramp down to solar minimum might not be occurring as they had predicted in April 2025.

This month I can lambast myself, because the Sun in February saw a significant drop in sunspots, including three consecutive days in which the Sun was blank of spots, for the first time since 2022. This drop supports the NOAA panel prediction and makes my prediction look foolish, but it also suggests the ramp down is continuing to go faster than predicted.

Indian rocket startup Agnikul completes static fire test of three-engine cluster

8:59 am

The Indian rocket startup Agnikul has now released a video of a 40-second static fire test of three-engine cluster it hopes to use on its Agnibaan orbital rocket.

The engines, powered by electric motor-driven pumps, were designed and manufactured in-house at Agnikul’s Rocket Factory-1. All three were fully 3D-printed as single-piece hardware units, reflecting the startup’s focus on advanced manufacturing and indigenous engineering.

Co-founder and chief executive Srinath Ravichandran said that increasing the number of engines improves rocket performance and that a three-engine system is required for commercial missions. The clustered test involved calibrating six pumps and six motors and fine-tuning six independent speed control algorithms to function in synchronisation. The goal was to achieve uniform startup, steady-state operation and shutdown performance across all three engines, a technically complex process given the precision required in semi-cryogenic propulsion systems.

The company has completed one suborbital test launch in May 2024, and in September 2025 said its orbital rocket’s first stage will land vertically and be reused.

Agnikul however has not released any schedule for launch, and based on this static fire test appears years from a first launch. It is making progress, but slowly. At the same time, it says it has raised $500 million in private investment capital, giving it the resources to build the rocket.

Based on testing and published progress, Agnikul appears to be trailing India’s other rocket startup Skyroot, though this could change in the coming year.

Cargo Dragon successfully returns to Earth

11:49 am

A cargo Dragon capsule successfully splashed down in the Pacific late Thursday, February 26, 2026, bringing back several thousand pounds of hardware and experiments.

The ship had been docked at ISS for the past six months, during which it used its engines six different times to raise the station’s orbit. That capability has traditionally been done by Russian Progress freighters, but NASA has been testing other options as they are unsure Russia will remain with the station after 2028. Furthermore, there are risks using Progress to do these reboosts, as the burns take place when Progress is docked to its Zvezda module port, and the hull of the Zvezda module has been developing stress fractures in the past five years that could catastrophically fail.

Not only has Dragon now demonstrated this boost capability, so has Northrop Grumman’s Cygnus capsule.

I strongly expect Russia to stick with ISS for as long as it can, mainly because its own proposed new space station is not likely to launch as presently scheduled later this decade. Since the fall of the Soviet Union, Roscosmos has consistently been unable to complete almost any new proposed projects, and the few it has completed launched literally decades late.

Rocket Lab completes another HASTE suborbital mission

10:45 am

Rocket Lab late yesterday successfully completed its seven HASTE suborbital mission, using the first stage of its Electron rocket to do a hypersonic test mission for the War Department.

In this case, the test vehicle was from the Australian company Hypersonix, and it lifted off from Rocket Lab’s Electron launchpad at Wallops Island in Virginia.

This was Rocket Lab’s second flight for this particular military agency in the past three months, and its eleventh overall launch from Wallops Island. The company’s quick reconfiguration of Electron for hypersonic suborbital testing made it possible for it to capture a bulk of the military’s suborbital hypersonic testing business that others, such as Stratolaunch, had hoped to win.

China outlines plans for manned space program

10:26 am

China’s state-run press today outlined a short update on the status of its manned space station program as well as its planned manned lunar landing, still targeting a 2030 launch.

For the space station, these are its upcoming plans:

China is scheduled to launch two crewed missions and one cargo spacecraft mission for its space station operation in 2026, according to the China Manned Space Agency (CMSA). An astronaut from the Hong Kong or Macao special administrative region is expected to carry out a space station flight mission as early as this year, the CMSA noted.

One astronaut from the Shenzhou-23 crew will conduct a year-long in-orbit stay experiment, the CMSA said.

I am willing to bet that China is planning an even longer station mission that will break Valeri Polyakov’s 14.5 month record mission, set in the 1990s on Mir.

As for China’s lunar landing plans, nothing new was announced:

China is targeting a crewed lunar landing by 2030. The development of major flight products, including the Long March-10 carrier rocket, the Mengzhou crewed spacecraft, and the Lanyue lunar lander, is proceeding smoothly. Key tests have been completed, including the zero-height abort test for the Mengzhou spacecraft, the landing and takeoff test for the Lanyue lunar lander, the static fire test and the low-altitude demonstration and validation test for the Long March-10 rocket system, and the maximum dynamic pressure escape test for the Mengzhou spacecraft system.

In 2026, the country will intensify efforts to advance the construction of supporting facilities and equipment for the lunar mission at the Wenchang Spacecraft Launch Site in southern Hainan Province, as well as the development of ground support systems.

China has not yet outlined a program of missions leading up to that lunar landing. Like Apollo and now Artemis, it makes sense to do low orbit rendezvous and docking tests of these various spacecraft before heading to the Moon. It also makes sense to do these same tests first in lunar orbit, before landing. Expect China to announce such a program soon, for launch in the 2027-2029 timeframe.

NASA’s corrupt Aerospace Safety Advisory Panel: NASA must be bigger and have more control!

11:36 am

Orion's damaged heat shield
Orion’s damaged heat shield after 2022 flight.
ASAP “Move along! Nothing to see here.”

NASA’s Aerospace Safety Advisory Panel (ASAP) today released its annual report, and once again it demonstrated why I have been calling it corrupt and a waste of money for years.

The report can be read here [pdf], but let me warn you that its findings have nothing to do with ASAP’s original purpose (created after the 1967 Apollo 1 launchpad fire that killed three astronauts), to look at NASA projects to make sure the agency is not ignoring specific safety issues.

Instead, as it has done repeatedly in recent years, the panel focused on management goals and larger strategic issues, and as usual concluded that the best way to do things is to make NASA bigger with more control over the entire space industry.

Europe tests a new engine design aimed at nothing

10:57 am

ESA: where projects go to die
The European Space Agency:
home of dead-end projects

The European Space Agency (ESA) today announced that it has successfully completed a static fire test program of a new rocket engine, dubbed Greta, that uses alternative fuels in order to save the environment.

Greta uses hydrogen peroxide and ethanol as propellants, a more sustainable alternative with a lower carbon footprint compared to monomethyl hydrazine propellant used by most traditional rocket engines in this thrust range.

Greta was ignited multiple times from July to November 2025 and showed stable operations, including controlled shutdowns. During the test campaign the engine fired continuously for over 40 seconds at a time. Greta was tested on a new, low-cost and versatile mobile test stand with instruments measuring data such as pressure and temperature, which will be used to further optimise the engine.

The problem is that this engine is not being built for any specific rocket or spacecraft. As the press release notes vaguely, “This type of engine could be used on lunar landers or on kick stages, such as Astris that is being developed for Europe’s Ariane 6 rocket.”

In other words, this is a test program only, and could very well end up on the scrap heap once completed, because it belongs to no private company aimed at making profits.

NASA did these kinds of projects for decades, all for naught. The agency would make a splash with its press release, the propaganda press would extol blindly the wonders that have been achieved, and then the project would complete and get quietly shelved, stored somewhere in the government archives (possibly in the same place they put Indiana Jones’ Ark of the Covenant).

ArianeGroup is building this engine for ESA, so there is a small chance the company might decide to use it in a future rocket or spacecraft, but only if it makes sense financially. And there is no indication that this engine’s development is tied to financial concerns, in the slightest. For example, the program only calls for another round of static fire engine tests — using “parts for the flight-like motor design” — in 2027, more than a year hence. At that pace the engine will be obsolete before tests are completed.

SLS is back in the Vehicle Assembly Building

9:43 am

Last night NASA yesterday successfully completed the roll back of its SLS rocket back to the Vehicle Assembly Building (VAB).

The SLS (Space Launch System) rocket and Orion spacecraft for NASA’s Artemis II mission arrived at the Vehicle Assembly Building from Launch Pad 39B at approximately 8 p.m. EST Feb. 25, at NASA’s Kennedy Space Center in Florida. While in the assembly building, technicians will troubleshoot the helium flow issue to the rocket’s upper stage, replace batteries on the rocket’s upper stage, core stage, and solid rocket boosters as well as service its flight termination system.

NASA officials have not said what will happen next, once that helium flow problem is resolved. I suspect NASA administrator Jared Isaacman will insist on another wet dress rehearsal to not only test the rocket’s troublesome fueling system, but to also test the helium system used to drain the tanks afterward.

If so, it is very unlikely a launch can occur prior to April 6th, when the present launch window closes. The odds of there being no issues on the next dress rehearsal are slim, based on SLS’s past record, and even if all goes well, the time margins are very very tight, allowing for no delays of any kind.

Space Force suspends use of ULA’s Vulcan rocket

9:36 am

Space Force officials yesterday made it official, that it has suspended all further military launches using ULA’s Vulcan rocket, due to the nozzle failure in one of the rocket’s solid-fueled strap-on boosters during the last launch on February 12, 2026.

The Space Force is pressing pause on all military launches on United Launch Alliance’s Vulcan rocket as officials investigate a recent anomaly they say could take “many months” to resolve.

That means launch plans for a GPS III satellite slated to fly on the brand new rocket next month are in flux, according to Col. Eric Zarybinsky, program executive officer for assured access to space. “I’m going to look for every flexibility I have to make sure that I can deliver warfighter capability as quickly as possible,” Zarybinsky told reporters at AFA’s Air Warfare Symposium here. “I’ve got a number of tools in my toolkit to do that, but until this anomaly is all over, we will not be launching National Security Space Launch missions on Vulcan.”

Though the rocket was able to get the payload to its proper orbit, despite the problem, this was the second Vulcan launch where a strap-on booster, built by Northrop Grumman, experienced a nozzle failure. In addition, another nozzle failure had occurred during a static fire test in 2025.

Prior to the February launch the Space Force had already shifted two launches from ULA’s Vulcan to SpaceX’s Falcon 9. At the moment ULA has seven military Vulcan launches scheduled for this year. Expect a considerable number to shift to SpaceX.

Blue Origin’s New Glenn rocket might also become an option, but the company must complete two more launches before the Space Force will certify it for national security launches. Considering that company’s slow pace in doing anything, it does not appear it will be able to take advantage of this situation.

ULA meanwhile had hoped to complete 18 to 22 launches in 2026, the majority using Vulcan. This decision by the Space Force likely means the company won’t complete more than five launches this year, most of which using its soon-to-be-retired Atlas-5 rocket.
