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.

SpaceX launches 25 more Starlink satellites

10:02 am

SpaceX early today successfully placed another 25 Starlink satellites into orbit, its Falcon 9 rocket lifting off from Vandenberg Space Force Base in California.

The first stage completed its 7th flight, landing on a drone ship in the Pacific.

The 2026 launch race:

29 SpaceX
8 China
3 Rocket Lab
2 Russia
1 ULA
1 Europe (Arianespace)

Not only is SpaceX this year leading the entire world combined in total launches — as it did in both ’24 and ’25 — at the moment its pace is about twice that as the rest of the globe.

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.

Dart changed the orbit of the Didymos/Dimorphos binary asteroids around the Sun

2:54 pm

Dimorphos just after impact

When the Dart spacecraft impacted the asteroid Dimorphos in September 2022, it not only shortened Dimophos’ orbit around its companion asteroid Didymos by about 33 minutes while reshaping the asteroid, a new study has found that it also changed very slightly the orbit of both asteroids around the Sun.

The image to the right, annotated to post here, was taken by the Italian LICIACube spacecraft moments after the September 26, 2022 impact.

The research paper describing this research can be found here. From the press release:

The new study shows the impact ejected so much material from the binary system that it also changed the binary’s orbital period around the Sun by 0.15 seconds. “The change in the binary system’s orbital speed was about 11.7 microns per second, or 1.7 inches per hour,” said Rahil Makadia, the study’s lead author at the University of Illinois Urbana-Champaign. “Over time, such a small change in an asteroid’s motion can make the difference between a hazardous object hitting or missing our planet.”

To be precise, the orbital speed was slowed 1.7 inches per hour, which while tiny would mean its solar orbit is now slightly shortened.

The result proves that a similar impact could be used on some asteroids to deflect them from hitting the Earth, though we would need to know a lot about that asteroid prior to launching the mission to accurately predict the orbital change. Otherwise, any impact could be a dangerous crap shoot that could do more harm than good.

Curiosity looks uphill at its upcoming travels

12:41 pm

Cool image time! Since May 2025 Curiosity has been exploring in great detail the boxwork formations located on the lower slopes of Mount Sharp. It is now about to complete those investigations, with the Curiosity science team beginning their planning for moving onward and upward.

The panorama above, enhanced to post here, was taken on March 2, 2026 by the rover’s right navigation camera. It looks uphill along the valley that Curiosity is in toward the mountainous region the rover is targeting. Note that the peak of Mount Sharp is not visible, being more than 25 miles away beyond the horizon and about 15,000 feet higher up.

The blue dot on the overview map to the right mark Curiosity’s present position. The yellow lines indicate roughly the area this panorama covers. The red dotted line marks the rover’s approximate planned route, while the white dotted line indicates Curiosity’s actual travels.

Right now Curiosity is traveling through a geological layer the scientists have dubbed the sulfate unit. The lighter colored hills seen on the horizon have also been identified as sulfate, but believed to be much more pure. The geology there should be very different. Instead of rough and rocky it could be like traveling over soft porous sand. This however is merely a guess on my part, based on imagery of those light-colored hills.

The actual route through those hills however remains unknown. Either the science team has not yet released it, or is still trying to figure out the best way through.

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

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.

Rocket Lab completes another launch yesterday

8:40 am

Rocket Lab yesterday successfully placed a satellite into orbit, its Electron rocket lifting off from one of its two launchpads in New Zealand.

The company did not reveal the name of its customer, though according to this source the satellite was a Blacksky Earth imaging satellite, the fourth launch of a four-launch contract with that satellite company.

The 2026 launch race:

28 SpaceX
8 China
3 Rocket Lab
2 Russia
1 ULA
1 Europe (Arianespace)

Not only is SpaceX this year leading the entire world combined in total launches — as it did in both ’24 and ’25 — at the moment its pace is about twice as much as the rest of the globe.

New Webb data says asteroid 2024 YR4 will miss the Moon in 2032

2:54 pm

New Webb data collected in February has now eliminated any chance the potentially dangerous asteroid 2024 YR4 will hit either the Earth or the Moon when it makes its next close pass on December 22, 2032.

Using data from NASA’s James Webb Space Telescope observations collected on Feb. 18 and 26, experts from NASA’s Center for Near-Earth Object Studies at the agency’s Jet Propulsion Laboratory in Southern California have refined near-Earth asteroid 2024 YR4’s orbit and are ruling out a chance of lunar impact on Dec. 22, 2032. With the new data, 2024 YR4 is expected to pass by the lunar surface at a distance of 13,200 miles (21,200 km).

Earlier less precise data had suggested 2024 YR4 had a 4.3% chance of hitting the Moon in 2032. That chance is now zero. This result is actually disappointing, in that an impact of this asteroid, estimated to be about 200 feet in diameter, would have not only been spectacular, but would have been scientifically useful. We would have been able to observe it closely with many ground- and space-based telescopes, and garnered a lot of useful information about the asteroid, the Moon, and the very nature of impacts.

The impact would have also eliminated the chance this asteroid might hit the Earth in the future. 2024 YR4 orbits the Sun about every four years. Previous calculations suggested another potentially dangerous fly-by of Earth in 2047, but these numbers are unreliable because the orbit will be changed by the 2032 fly-by in ways that cannot be predicted as yet.

Vast raises $500 million in new private investment capital

1:47 pm

Haven-2
Vast’s full Haven-2 station once completed

The space station startup Vast today announced it has raised another $500 million in new private investment capital, bringing the total so far invested in the company’s space station project to more than one billion.

The financing round was led by Balerion Space Ventures with participation from IQT, Qatar Investment Authority (QIA), Mitsui & Co., Ltd, MUFG, Nikon Corporation (Nikon), Stellar Ventures, Space Capital, and Earthrise Ventures. Jed McCaleb, founder and first investor, also participated in the round. As part of the transaction, Balerion Advisor A.C. Charania, former Chief Technologist for NASA, will join the Vast board.

…To date, more than $1 billion has been invested in Vast’s space stations technologies and facilities—resources that NASA and government partners can leverage to ensure readiness to replace the ISS in 2030. The latest financing includes $300 million in Series A equity and $200 million in debt to support the continued development of Vast’s Haven space stations. The funds will be used to expand facilities, grow the team, and advance the company’s proposed successor to the ISS, Haven-2, designed to ensure continuous human presence in low-Earth orbit for the United States and its allies.

Hat tip to reader Richard M for letting me know about this announcement.

In my rankings below of the five American commercial space stations presently in development, I rank Vast #1. This new investment helps solidify its first place standing.
