SpaceX launches 29 more Starlink satellites

11:47 am

SpaceX today successfully placed another 29 Starlink satellites into orbit, its Falcon 9 rocket lifting off from Cape Canaveral Space Force Station in Florida.

The first stage (B1069) completed its 31st flight, landing on a drone ship in the Atlantic, 63 days after its previous flight. It remains in 6th place in the rankings of the most reused launch vehicles:

39 Discovery space shuttle
34 Falcon 9 booster B1067
33 Atlantis space shuttle
32 Falcon 9 booster B1071
32 Falcon 9 booster B1063
31 Falcon 9 booster B1069
28 Columbia space shuttle
27 Falcon 9 booster B1077
27 Falcon 9 booster B1078

Next Artemis mission will be later than promised

9:20 am

Artemis logo

It appears that NASA has already recognized that the next Artemis mission, dubbed Artemis-3 and changed from a lunar landing to an Earth orbit test flight, will not happen on the schedule as first proposed by NASA administrator Jared Isaacman.

During the hearing on Monday, Congressman Hal Rogers (R-Ky.), chairman emeritus of the committee, asked Isaacman about his confidence that Artemis 3 would remain on schedule, given the amount of money allocated for the mission’s landers.

“I’ve received responses from both vendors [SpaceX and Blue Origin],” Isaacman said, “to meet our needs for a late 2027 rendezvous, docking and test [of] the interoperability of both landers in advance of a landing attempt in 2028.”

That’s a shift from Isaacman’s statements during his Feb. 27 Artemis strategy presentation, during which he said, “Artemis 3 will have its opportunity, if we can, by mid-2027, which sets us up for an early ’28 and a late ’28 opportunity [for Artemis 4 and 5].” [emphasis mine]

In other words, Artemis-3 has already shifted from mid-’27 to late-’27. Though Isaacman is pushing hard to speed up the launch cadence of the entire Artemis program, reality is once again proving stronger. We should fully expect Artemis-3 to shift into 2028, partly because the lunar landers — especially Blue Origin’s Blue Moon — might not be ready but mostly because SLS is simply too cumbersome a rocket to stack quickly. Isaacman wants to speed up its launch cadence to once a year. The best we should expect is 18 months to two years.

As for getting two manned lunar landings in 2028, Isaacman might want it but the odds are slim to none. If Artemis-3 flies in late ’27 it will be almost impossible to get SLS ready for a landing mission before the end of ’28.

In the end, these delays will illustrate the need to replace SLS with private commercial launchers.

FCC approves new spectrum rules to give new constellations more capacity

9:00 am

The Federal Communications Commission (FCC) yesterday approved new spectrum rules proposed by SpaceX that will increase the capacity of all the new low-Earth-orbit constellations by as much as seven times.

The commission introduced the new rules earlier this month before approving them at a Thursday meeting. The revamp targets the Equivalent Power Flux Density (EPFD) rules, which were developed in the late 1990s and limited the amount of energy satellite systems could transmit to and from ground equipment. The regulations were also designed to prevent radio signal interference between higher-orbiting geostationary satellites and lower-orbiting systems. But during the vote, Carr said the decades-old existing rules were “holding back” newer satellite internet offerings.

“Modern satellite designs make it far easier to share spectrum than what yesterday’s regulations assumed. We can do a lot better,” he said. Carr touted the 7x increase when the commission found the revamped rules could enable “eight satellites to provide service simultaneously in a given geographic area and frequency band, instead of being effectively limited to one satellite under current EPFD limits.”

The FCC was sold on this change after SpaceX conducted its own tests in orbit, using Starlink satellites, to demonstrate it could work. The rule change will benefit all the new constellations, which is why Amazon’s Leo constellation supported the change as well.

The speed in which the FCC acted on this matter must also be noted. It did not bother with long studies of its own. It quickly reviews SpaceX’s work, realized it made sense, and scheduled the vote at its very next meeting. This constrasts starkly with the FCC during the Biden administration, which routinely slow-walked or even opposed such suggestions.

House Appropriations committee approves NASA budget, with some cuts proposed by Trump

8:50 am

In what is no surprise if one watched last week’s House hearing about the NASA budget, the House Appropriations committee yesterday approved a NASA budget for fiscal year 2027, giving the agency the same funding it had in 2026, just over $24 billion, rejecting Trump’s proposed major reduction in the budget of over $5 billion.

The vote was along party lines, with the Republicans approving and the Democrats opposing. As expected, while the overall budget was maintained, the Republicans went along with the sense of Trump’s cuts — and the desires of NASA administrator Jared Isaacman — by shifting money from science to exploration within the budget.

The subcommittee bill provides $8.926 billion for human exploration, an increase of about $400 million above the request, and the request itself favors exploration. … The subcommittee’s bill raises the FY2027 level for [NASA science] to $6 billion, but that’s still a $1.3 billion reduction from current spending as Ranking Member Grace Meng (D-New York) pointed out.

The bill also agreed with Trump’s proposal to eliminate NASA’s STEM education office, something Isaacman had repeatedly testified was redundant and a waste of money.

In other words, the committee is giving Isaacman more flexibility with the money it is giving him, as I predicted.

This is only the first step in the budget process. The budget still has to be approved by the full House, the Senate, and the President. Expect changes.

Russia completes 1st test, suborbital, of its new Soyuz-5 rocket

8:21 am

According to Russia’s state-run press, it successfully completed the first suborbital test flight of its new Soyuz-5 rocket, the rocket lifting off from Baikonur in Kazahkstan on April 28, 2026 carrying a dummy payload.

A special launch was conducted today as Soyuz-5, a new Russian carrier rocket with the world’s most powerful liquid-fuel engine, blasted off. <...> Operating the rocket will make it possible to substantially reduce the unit cost of the payload capacity. This will have a positive impact on the economics of space launches,” the Russian state-owned space corporation quoted its CEO Dmitry Bakanov as saying.

The rocket will eventually be able to place about 17 tons in low Earth orbit, making it more powerful than the Soyuz-2 — now used to launch capsules and satellites — but less powerful than Russia’s Proton rocket, used to launch station modules and other more demanding missions.

Soyuz-5 however is not reusable, so it will remain more expensive to use that the new rockets being developed everywhere else outside Russia. Like all of Russia’s rockets, stages will continue to fall inside Russia with each launch. In this case, the first stage and fairings crashed somewhere in Russia, while the second stage splashed down in the Pacific.

Ireland to sign Artemis Accords

8:01 am

According to a NASA press release late yesterday, Ireland will sign the Artemis Accords on May 4, 2026, becoming the 65th nation to join this American space alliance.

NASA Administrator Jared Isaacman will host Ambassador of Ireland to the United States of America Geraldine Byrne Nason; Minister for Enterprise, Tourism and Employment Peter Burke, T.D., of Ireland; and U.S. Department of State officials for the ceremony.

As I predicted yestesday when Morocco signed the accords, the success of the Artemis-2 mission around the Moon has prompted a number of smaller third world countries to finally sign the accords, and thus should expect more signings to follow. Ireland illustrates this. There will be more soon.

The full list of nations in this American space alliance is as follows:

Angola, Argentina, Armenia, Australia, Austria, Bahrain, Bangladesh, Belgium, Brazil, Bulgaria, Canada, Chile, Colombia, Cyprus, Czech Republic, Denmark, Dominican Republic, Ecuador, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, India, Ireland, Israel, Italy, Japan, Jordan, Latvia, Liechtenstein, Lithuania, Luxembourg, Malaysia, Mexico, Morocco, the Netherlands, New Zealand, Nigeria, Norway, Oman, Panama, Peru, Poland, Portugal, Romania, Rwanda, Saudi Arabia, Senegal, Singapore, Slovakia, Slovenia, South Korea, Spain, Sweden, Switzerland, Thailand, the Philippines, the United Kingdom, the United Arab Emirates, the Ukraine, the United States and Uruguay.

The present state of India’s space program

10:44 am

India's Bharatiya Antariksh Station as outlined in 2024
India’s Bharatiya Antariksh Station as outlined in 2024.

India’s space agency ISRO yesterday released its annual report [pdf], outlining its accomplishments over during 2025.

Like all such reports, it is filled with glowing superlatives. It provides little concrete information about the agency’s more serious issues, such as what it is doing to fix the upper stage of its PSLV rocket, which has failed on the last two consecutive launches. All the annual report says on this subject is the following:

Based on the recommendations of the National Level Committee comprising of eminent experts from academia & industry, the third stage of PSLV i.e., HPS3 motor with modified design was realised and two static tests were successfully completed on October 06, 2025 and November 19, 2025 as in flight, from SDSC, SHAR. The overall performance of the motor and subsystems were as expected and closer to nominal performance.

The problem is that these fixes and tests did not work. The second failure of the upper stage occurred in January 2026, less than two months later. The annual report should have noted this fact, but did not.

As for India’s planetary program, digging out the present schedule from the report is difficult. Based on this review of the annual report, the dates are as follows:

  • Chandrayaan 4 lunar sample return mission: October 2027.
  • Venus Orbiter: March 2028.
  • Chandrayaan 5 /LUPEX lunar lander: September 2028.
  • Mars Lander: No target launch date as yet.

Expect these dates to be delayed.

The report also gives a detailed description on India’s Gaganyaan manned program, but little information about the planned unmanned tests that were planned for this year, leading to a manned orbital mission next year. At the moment the schedule appears to be experiencing delays, caused mostly by the PSLV launch failures. It appears ISRO wants this issue resolved before it launches that first unmanned Gaganyaan test flight.

If you want to get an overview of India’s government space program, this annual report is a good place to start. It will at least provide a baseline on which you can build a deeper knowledge.

Falcon 9 upper stage to hit the Moon in August

9:28 am

Falcon 9 impact on Moon in August
Click for original image.

According to astronomer Bill Gray, who also tracks orbital objects, the upper stage of the Falcon 9 that launched Firefly’s Blue Ghost and Ispace’s Hakuto-R2 lunar landers in January 2025 will hit the Moon on August 5, 2026.

For some time, I’ve provided some software tools astronomers can use to identify satellites in their data. I use the US military’s publicly available satellite data for many objects, and compute orbits for high-orbiting objects the military doesn’t track.

This object falls squarely in the latter category. In September 2025, my software for computing orbits analyzed the observations and projected an impact with the moon on 2026 August 5.

While this looked like a pretty solid prediction, I couldn’t be totally sure of it at the time. The motion of space junk is mostly quite predictable; it simply moves under the influence of the gravity of the earth, moon, sun, and planets. We know those with immense precision. If those were the only factors involved, I could probably tell you where and when this object would hit the moon to within a few meters and a fraction of a second.

The problem is that space junk in general, and 2025-010D in particular [the upper stage], is also pushed around by sunlight (“solar radiation pressure”). This is an extremely gentle force, but over months, it can really build up. And it’s not entirely predictable. As an object tumbles, it may catch more or less sunlight, and may reflect some of it sideways. So sunlight is mostly pushing the object away from the sun, but there’s a slight bit of pushing in other directions as well.

With enough data, we can actually figure out where the forces are pushing an object. But they do change a little over time in ways that aren’t perfectly predictable. So I can be sure it will impact near the time and place I’ve predicted, but those varying forces mean that the actual impact will be at least a little off from that time and place. That’s the largest source of uncertainty in all this, and there’s no way to correct for it; we just have to wait and see what actually happens. (But come August, we’ll have a quite precise idea of where it will hit.

At present, Gray predicts the impact will occur at 2:44 am (Eastern) on August 5, 2026. The image above is his present estimate of where it will hit, as seen from Earth. If this prediction holds, the impact itself will likely not be visible from Earth, as it will occur in daylight and at the very western limb of the Moon. This prediction however could change somewhat in the next few months.

When it hits Gray estimates the stage will be moving at about 5,400 miles per hour, or 1.51 miles per second. Expect the science team for Lunar Reconnaissance Orbiter (LRO) to try to image this impact after the fact.

Morocco signs the Artemis Accords

8:51 am

The State Department yesterday announced that Morocco has become the 64th nation to sign the Artemis Accords.

Moroccan Foreign Minister Nasser Bourita signed the Accords on behalf of the Kingdom of Morocco on April 29 at a ceremony in Rabat, Morocco. U.S. Deputy Secretary of State Christopher Landau and U.S. Ambassador to Morocco Duke Buchan III witnessed the signing.

It does appear that the success of the Artemis-2 mission around the Moon has prompted a number of smaller third world countries to finally sign the accords. Before the mission there had been a slow-down in new signatories. In only the past two weeks however Latvia, Jordan, and now Morocco have joined. We should expect more in the coming months, because they all want to get in on the game, while the getting is good.

The full list of nations in this American space alliance is as follows:

Angola, Argentina, Armenia, Australia, Austria, Bahrain, Bangladesh, Belgium, Brazil, Bulgaria, Canada, Chile, Colombia, Cyprus, Czech Republic, Denmark, Dominican Republic, Ecuador, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, India, Israel, Italy, Japan, Jordan, Latvia, Liechtenstein, Lithuania, Luxembourg, Malaysia, Mexico, Morocco, the Netherlands, New Zealand, Nigeria, Norway, Oman, Panama, Peru, Poland, Portugal, Romania, Rwanda, Saudi Arabia, Senegal, Singapore, Slovakia, Slovenia, South Korea, Spain, Sweden, Switzerland, Thailand, the Philippines, the United Kingdom, the United Arab Emirates, the Ukraine, the United States and Uruguay.

Two launches yesterday

8:39 am

Both SpaceX and Arianespace successfully completed orbital launches yesterday. First, SpaceX placed another 24 Starlink satellites into orbit, its Falcon 9 rocket lifting off from Vandenberg Space Force Base in California. The first stage completed its 13th flight, landing on a drone ship in the Pacific.

Next, Arianespace placed 32 more Amazon Leo satellites in orbit, its Ariane-6 rocket lifting off from France’s French Guiana spaceport in South America. The expendable Ariane-6 launched for the second time in its most powerful configuration, with four side boosters. This was also Arianespace’s second launch this year, so it remains off the leader board below.

With this launch, Amazon now has 302 Leo satellites in orbit, out of the 1,616 it needs to launch by July to meet its FCC license requirement. The company’s request for a time extension is presently pending at the FCC.

The leaders in the 2026 launch race:

52 SpaceX
23 China
8 Russia
6 Rocket Lab

For the third straight year SpaceX continues to lead the entire world combined in total launches, 52 to 44.

Russia was also supposed to do a test suborbital launch of its new Soyuz-5 rocket. As of posting I have not been able to confirm whether the launch took place.

Canada cancels $72 million contract to build constellation to track wildfires

9:48 am

In what appears to be an unexpected decision, the Canadian government this past week suddenly terminated a $72 million contract with the company Spire Global Canada to build a constellation of satellites designed to locate and track wildfires.

According to a Form 8-K filed with the U.S. Securities and Exchange Commission, Spire Global received a written notice on April 23, 2026, from the Minister of Public Works and Government Services (PWGS) terminating the agreement “for convenience,” effective immediately. The Phase B and C contract would have had an aggregate value of $71.8 million, including harmonized sales tax, if all contractual milestones had been achieved. The value of the overall WildFireSat satellite constellation including Phase D for manufacturing, system assembly, and integration is $106 million.
WildFireSat mission setback

This represents a serious setback for the Canadian Space Agency (CSA) and other government departments who are participating in the mission. Only a month ago the project was being touted as high return-on-investment climate mission in the annual Canadian Space Agency 2026–27 Departmental Plan.

The plan had called for a constellation of nine smallsats, with one back-up ready for launch on the ground.

No reason has been given for the cancellation. The Canadian Space Agency merely stated that “The Government of Canada will soon be engaging with industry and begin working closely with stakeholders on how best to advance the continued development of this important mission.” Spire Global meanwhile has until May 7th to apply for settlement costs.

Rocket Factory Augsburg submits license application for a Saxavord launch window opening on July 1, 2026

8:30 am

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

The German rocket startup Rocket Factory Augsburg has now submitted a new marine license application to allow it to attempt the first launch of its RFA-1 rocket from the Saxavord spaceport on the Shetland Islands in Scotland, with a launch window opening on July 1, 2026.

Rocket Factory had hoped to do this launch in 2024, but lost the first stage mere weeks before launch when it exploded during a final static fire test on the launchpad. Since then the company has undergone a management shake-up and made major changes to operations and its rocket.

To do this launch, however, it needs a new launch license, and that is a major problem. The company’s announcement is filled with numerous vague qualifiers, as it knows getting the bureaucracies in the United Kingdom to move quickly in this matter is nigh on impossible.

This is a legally required step for planning, and a good sign of how far we’ve come – but it’s not a launch date just yet. We applied for this window because we’re working hard to be ready – and we’re getting closer every day.

So: the application means we’re entering a new phase of preparation. Still, as with any first-ever launch, there are uncertainties, and the schedule may evolve. Further specific details around launch timing will be released through the appropriate channels closer to the time. We’ll keep you posted!

In other words, the company will not be surprised if it doesn’t get its license in time for July, and is prepared for delays.

Another German rocket startup, Isar Aerospace, has been trying to launch its Spectrum rocket from Norway’s Andoya spaceport since January, with the launch scrubbed several times due to technical issues. Right now the launch its tentatively scheduled for May, which means the race to achieve the first orbital launch from Europe is tightening considerably.

If I had to place a bet, my money would be on Isar, not Rocket Factory, and the reason would be because I truly doubt the British bureaucracy will issue a license on time. Its track record has been abysmal, sometimes taking years to give an okay. In this case it might not take that long, since Saxavord has gotten all its own permits already (after years of waiting) but no one should be confident it will act with speed. And it is clear that the people at Rocket Factory are not.

California Coastal Commission settles SpaceX lawsuit by apologizing and conceding all points

8:01 am

Wants to be a dictator
Wanted to be a dictator; ended up being
a patsy.

SpaceX yesterday settled its lawsuit [pdf] with the California Coastal Commission when the commission agreed to apologize to the company and agree it has no authority to regulate any SpaceX launches at Vandenberg Space Force Base.

The Commission agrees that it may not consider irrelevant factors in performing its function and specifically agrees that it will not take into account the perceived political beliefs, political speech, or labor practices of SpaceX or its officers in considering any regulatory action concerning SpaceX. The Commission acknowledges that Commissioners made statements, including during their October 10, 2024, hearing on the Base’s Falcon 9 launch program, that showed political bias against SpaceX and its CEO and were improper. The Commission apologizes for those statements, as set forth in the signed letter attached as Exhibit C.

The commission also agreed that it has no authority to regulate SpaceX’s launch rate at its launchpads at Vandenberg, and will never again attempt to interfere with these operations.

The SpaceX lawsuit stemmed from the comments made by the commissioners at a meeting in October 2024 when then voted against the military’s plan to allow SpaceX to increase its launch rate at Vandenberg spaceport to up to 50 launches per year. In those comments, the commissioners made it clear that the main reason they were voting against the motion was because they were offended by Elon Musk and his political positions, not because the company was doing anything wrong.

While the settlement does not restrict the commission’s right to regulate off-base actions, or other aspects under its statutory authority, this settlement is a complete victory for SpaceX. The commission members were probably made aware that if they didn’t back down completely, they would be personally liable for a great deal of damages. As a result of this settlement, they are absolved of all liabilities.

A cool crater in Starship’s prime candidate zone on Mars

11:14 am

Overview map

Crater in the Starship landing zone on Mars
Click for original image.

Cool image time! The picture to the right, rotated, cropped, reduced, and enhanced to post here, was taken on August 16, 2025 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). In mid-March it was featured as a captioned image by MRO’s science team. From their caption:

When they form, impact craters dig up material from below the surface and throw it outwards into what geologists call an ejecta blanket. The fastest ejected material travels the furthest so material from different depths can end up at different distances from the crater.

This HiRISE image shows a pedestal crater in Arcadia Planitia that has material of different brightness and color at various distances from the crater. This could tell us more about the material that’s buried below the surface here, but the situation is complex.

The caption however fails to mention the most interesting two aspects of this crater’s ejecta blanket. One, it suggests strongly that there was a lot of near surface ice at impact that melted to produce this splash apron.

Second, and even more intriguing, the 3,100-foot-wide unnamed crater is located smack dab in the middle of the candidate landing zone on Mars for SpaceX’s Starship spacecraft, as shown by the overview map above. The white dot marks the location of this crater, while the red dots mark the four prime landing sites, as suggested by scientists in a 2021 paper [pdf], based on conclusions drawn from two workshops organized by SpaceX and these scientists. The other dots are other MRO images of this region, and include a number of potential secondary landing sites.

This zone is in the northern lowland plains of Mars, in a mid-latitude region where near-surface ice is plentiful. The splash apron of this crater provides further evidence of that near surface ice.

FAA to begin taxing launches by payload weight

8:44 am

FAA logo

As per the provisions in last year’s reconciliation budget bill (dubbed for propaganda reasons by Trump the “One Big Beautiful Bill Act”), the FAA was authorized to begin charging fees (another word for taxes) on the mass of each launch payload. The agency last week announced it is now doing so.

More information here.

For 2026, that fee is 25 cents per pound of payload, capped at $30,000 per launch or reentry. The fees would fund work on improving integration of launches and reentries into the national airspace system directed by an FAA reauthorization act in 2024.

Though the amount per launch is small compared to the cost of the launch itself, this new tax is expected to provide ample funds to allow the FAA to expand its licensing operations to meet the growing launch industry. The real challenge will be whether the bureaucracy can stay focused on its main task of serving the public, or use the money to build a new bureaucratic empire aimed at garnering power over the private sector. History suggests we should be pessimistic, and expect the latter.

In the meantime, rocket companies are simply going to apply this new tax to the makers of their payloads, who in turn will have their customers pay the cost.

ULA launches 29 Leo satellites

8:29 am

ULA last night successfully launched another 29 Amazon Leo satellites into orbit, its Atlas-5 rocket lifting off from Cape Canaveral Space Force Station in Florida.

ULA is in the process of retiring the Atlas-5 rocket. It now has only eight Atlas-5 rockets left in stock, with two reserved for Leo launches and six for Boeing’s Starliner manned capsule (though there is a good chance some if not all of the Starliner launches will be switched to other payloads). Because its Vulcan rocket, intended to replace Atlas-5, is presently grounded, the company appears to be accelerating Atlas-5 launches, with this launch only about 24 days after the previous launch.

With this launch, Amazon now has 270 Leo satellites in orbit, out of the 1,616 it needs to launch by July to meet its FCC license requirement. Because it is not expected to meet that requirement, the company has asked for a time extension, which the FCC is presently considering.

As this was only the third launch by ULA in 2026, the leader board for the 2026 launch race remains unchanged:

50 SpaceX
23 China
8 Russia
6 Rocket Lab

For the third straight year SpaceX continues to lead the entire world combined in total launches, 50 to 43.

An excellent overview of AST SpaceMobile following the New Glenn launch failure

10:51 am

Link here. For an article in a mainstream media outlet the writing is remarkable in its general accuracy and understanding of the larger context. It is also quite thorough, covering all aspects of AST SpaceMobile’s business model and how it stacks up against its main competitor, SpaceX’s Starlink.

According to the article, the company still hopes to get as many as 45 of its large new Bluebird satellites in orbit by the end of this year, though it admits the New Glenn failure now makes that goal more difficult. As the article notes:

AST SpaceMobile is continuing to manufacture, assemble and test satellites in Midland, and it will soon ship three new BlueBird satellites for launch on a yet-to-be-announced rocket. [emphasis mine]

That unnamed rocket is likely the Falcon 9, but at some point AST must find other rockets, as there is likely a limit to how many launches SpaceX can provide. Both ULA’s Vulcan rocket and Blue Origin’s New Glenn are both presently grounded because of launch failures, and other than SpaceX’s Falcon-9 and Falcon Heavy they are the only American rockets capable of launching the Bluebirds. It is also doubtful AST can buy flights on Europe’s Ariane-6 rocket. Though that rocket has had trouble garnering customers because of its high cost, its operator, the European Space Agency’s (ESA) commercial agency Arianespace, has also been very slow to ramp up operations. Even if AST was willing to pay a premium, Arianespace would likely not be able to fit extra launches into its schedule.

Overall, this situation illustrates a great opportunity. There is a strong demand for rockets from the satellite industry that the present rocket industry — excluding SpaceX — has been unable to meet.

Starlink returns to Papua New Guinea after court ruling

9:22 am

SpaceX’s Starlink internet service will once again be available in Papua New Guinea after its court this week overturned a ban that had been imposed by a government bureaucracy.

In early 2024, the [Ombudsman] Commission blocked licensing efforts for Starlink, arguing that existing regulations may not be adequate to manage potential risks to public interest and safety.

But in her National Court ruling last week, Judge Susan Purdon-Sully strongly criticised the Ombudsman Commission for its move to halt Starlink’s license process. Finding no breach of PNG’s leadership code, nor evidence of corruption, the judge said the Ombudsman’s concerns were more administrative, meaning its directive to NICTA had been “an unconstitutional exercise of power”.

Meanwhile, the prime minister again urged Starlink to work collaboratively with state-owned Telikom PNG to “ensure a coordinated rollout that complements national infrastructure priorities”.

The article describes in detail several recent natural disasters where the lack of Starlink was a critical component in rescue and repair operations. The country also has large rural areas where Starlink is the only method for reaching the rest of the world quickly. There was thus apparently great political pressure to end this ban.

Avio makes more from its Vega-C rocket now that Arianespace is out of the picture

9:07 am

According to a report today at Europeanspaceflight.com, the European Space Agency (ESA) paid Arianespace €51.65 million ($60.6 million) for a December 2024 launch using the Vega-C rocket that the Italian company Avio produces.

That flight was one of the last ones managed by Arianespace. In November 2025 ESA completed the transfer of ownership back to Avio, so that the company now manages and sells its own rocket, rather than have a middle-man government agency run things and take a cut.

Since then Avio has won three separate launch contracts, one from Taiwan for $81 million, another from Brazil for $35.6 million, and a third from Airbus for $84.4 million (see here).

Based on these numbers, it appears that Avio is doing much better selling this rocket directly to the market than having Arianespace and ESA run things for it. It is not only generally getting slightly more revenue per launch (about $67 million average compared to $60.6 million under Arianespace), but it is keeping all the profits, rather than having the Arianespace government bureaucracy take a percentage.

These numbers however won’t hold in the coming years. In the U.S. in the next year at least two reusable rockets — Rocket Lab’s Neutron and Stoke Space’s Nova — are coming on line, and will drive these launch prices down. Furthermore, new smallsat rockets being developed in Germany (two), Spain, India (two), South Korea, and Australia should do the same.

At the moment however Avio is benefiting from the present state of the market, though even that advantage is threatened because it has had to delay the next Vega-C launch due to a technical issue.

Regardless, these numbers give us a strong sense of the present competitive launch costs in today’s market, averaging about $60 million per launch. Before SpaceX came along, that price generally exceeded more than $100 million, and often as high as $200 to $500 million. No more. SpaceX has forced competition on the industry, and the result has been a notable drop in price, with more to come.

Australian rocket startup Gilmour pinpoints cause of first rocket launch failure

Eris rocket launch and failure

The Australian rocket startup Gilmour Space on April 24, 2026 released the results of its investigation into the launch failure seconds after liftoff of its Eris rocket in July 2025.

Our investigation found that approximately nine seconds after ignition, one of the four first-stage hybrid rocket motors experienced a loss of thrust. A second motor exhibited similar behaviour at around 17 seconds, reducing vehicle performance and bringing the mission to an early end.

Analysis identified two independent failure modes originating from the oxidiser pump subsystem. Electrical and thermal faults were observed in the electric pump motors and associated inverters, including components sourced from an external supplier. We now have a clearer understanding of the underlying causes.

The company hopes to try again later this year, but to do so it will need license approval from Australia’s bureaucracy, and such approvals have not been quick.

Trump fires the entire governing board of the National Science Foundation

2:38 pm

In a move that should surprise no one at this point in Trump’s second term, yesterday President Trump informed all 24 members of the National Science Board, the committee that runs the National Science Foundation (NSF), that they have been fired.

“On behalf of President Donald J Trump, I am writing to inform you that your position as a member of the National Science Board is terminated, effective immediately,” reads a 24 April email from Mary Sprowls of the presidential personnel office to each NSB member. “Thank you for your service.”

The article at the link, from the journal Science, takes the typical one-sided propaganda press anti-Trump view, interviewing only those who oppose Trump and spending most of its time screaming “He’s destroying science!”

A wider view would ask this: Is there a reason that the president of the United States, elected by the American people, might have reasons to question the management of this board? At the moment the federal government is running a deficit that is back-breaking, and this board publicly criticized Trump’s effort to rein in spending when he proposed a 55% cut in NSF’s budget. If they are not going to cooperate with their boss, then maybe they should leave, and not let the door hit them as they head out.

The Science article also included this howler: “the mass firing is the latest indication that the White House is ignoring the board’s authority and dictating policies at NSF.” Um, who elected them? No one. In fact, they were appointed by the president himself, and he is the only one with the constitutional authority to decide these matters.

Expect court suits of course, with some lower level unelected judge somewhere attempting to take over running the executive branch by demanding these board members remain in power, defying the elected president of the U.S.

Two space station startups strengthen their positions

11:17 am

The American space stations under development

The startups building the commercial space stations Haven-1 and Starlab this week made deals that will further strengthen their positions both to win future NASA contracts while also making their own operations more functionally viable.

First, Vast, which hopes to launch its Haven-1 single module demonstration station next year and follow it up with its full Haven-2 station (as shown to the right), signed a deal with former NASA astronaut Sunita “Suni” Williams, making her the fifth astronaut to join the company’s astronaut advisory committee.

Former NASA astronaut and U.S. Navy Captain Sunita “Suni” L. Williams has joined Vast as an Astronaut Advisor. She joins Vast’s esteemed group of Astronaut Advisors led by Lead Astronaut Andrew Feustel, including Garrett Reisman, Megan McArthur, and former JAXA astronaut and Vast Japan General Manager Naoko Yamazaki.

It is clear each one of these former government astronauts sees the possibility of flying again to Vast’s Haven-1 station, which the company hopes to have occupied four times for two weeks during its three year mission. They are also hoping to be part of the much larger Haven-2 station to follow.

Vast in turn is now assembling a staff of very experienced professional astronauts it can use to lead all these proposed missions.

Next, Voyager Technologies, the lead company in the consortium building the single-module large Starlab station that will launch on Starship, signed an agreement with Yonsei University in Seoul, South Korea. While initially the deal will have the university do research at Voyager’s research facility in Ohio, it also lays the groundwork for the univesity to eventually get access on Starlab, once launched.

For Voyager this deal helps show NASA that there is a real market for these private stations, something NASA administrator Jared Isaacman has expressed doubts about.

In my rankings below of the five stations under development, the first three stations remain essentially tied for first place.

Indian rocket startup Skyroot now shipping its Vikram rocket to launch site

9:54 am

The Indian rocket startup Skyroot has now finished assembling its Vikram-1 rocket, and is about to ship it to its launch site at the Sriharikota spaceport on the east coast of India.

At Sriharikota, the rocket moves into final assembly and a round of system checks before a launch window is locked in the coming months. This is the last stretch before liftoff. Countdown operations, testing and integration now shift fully to the launch site.

One of the company’s founders said the most critical testing has been completed, with launch campaign activities set to begin at the spaceport.

The company is presently targeting a launch in June. If Vikram-1 reaches orbit successfully, Skyroot would become the first Indian private company to design, build, and launch its own rocket, and would be well positioned to win launch contracts from smallsat companies, competing directly with Rocket Lab and its Electron rocket.

This success would also help accelerate the Modi government’s effort to transition from a space industry controlled entirely by its government space agency ISRO to a private industry run by competing indepedent companies.

Why is Sierra Space’s Dream Chaser spacecraft not ready for flight?

9:39 am

In a press release posted last week Sierra Space proudly announced that its Tenacity Dream Chaser mini-shuttle has completed its pre-launch ground vibration tests at the Kennedy Space Center in Florida, but instead of moving the mini-shuttle to a local facility where it could be integrated with its rocket for launch, the company announced it was shipping it back “to Colorado for final modifications and mission-specific upgrades.”

Normally when a spacecraft, satellite, or any payload passes these last ground tests, it is ready for launch, and it immediately begins integration onto the rocket that will carry it into space. That Sierra Space is not doing this strongly suggests Tenacity did not pass with flying colors, and that some issues were identified that need correction.

Note too that this spacecraft had been delivered for these tests in early 2024, and had been expected to pass them then and be launched that year. Instead, months passed with no word, then its launch was postponed indefinitely, and then NASA canceled Sierra’s contract to provide cargo to ISS.

Now, two years later Tenacity is still not ready for launch. Though the company says the ground tests are now complete, I suspect otherwise. I suspect there is some fundamental issue with the spacecraft that they are hiding because to reveal it would be devastating to Sierra’s public reputation.

Until we know more however this is pure speculation on my part. What we do know however is that this mini-shuttle has not done what was promised, and increasingly appears to be a lemon that will never do it.
