Will Canada’s Telesat really complete its Lightspeed constellation by 2028?

11:26 am

According to the most recent financial report from the Canadian satellite communications company Telesat, it expects its Lightspeed low-Earth-orbit (LEO) satellite constellation to be launched and operational by 2028.

During the first quarter, Telesat invested $171 million into the Lightspeed program, reflecting $19 million in operating expenses and $152 million in capital expenditures, bringing its total investment to date to approximately $2.7 billion.

The company reported advancing through several technical milestones in early 2026. “During the quarter, we held further design reviews with our satellite and launch vehicle dispenser manufacturers and progressed our work on user terminals, network and satellite operations software development, and ground station deployments,” noted Telesat President and CEO Dan Goldberg.

The company confirmed it remains fully funded, utilizing cash on hand and existing financing facilities, to reach full global commercial service around the end of the first quarter of 2028.

At the moment however the company has launched no satellites in this LEO constellation. Moreover, in a recent amendment to its FCC application, the company reduced the size of the constellation from 1,671 satellites to only 300, with no explanation.

We shall see what happens. My instincts sense a bit of blarney here. This constellation will likely launch, but I think the company’s proposed schedule is questionable.

Genesis cover

On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.

 

The print edition can be purchased at Amazon or any other book seller. If you want an autographed copy the price is $60 for the hardback and $45 for the paperback, plus $8 shipping for each. Go here for purchasing details. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.


The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
 

"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

Curiosity unintentionally picks up a rock slab

11:15 am

Sequence showing slab picked up and then dropped
Click for movie. Original images found here, here, here, and here.

In their latest drilling campaign using the drill on the Mars rover Curiosity, the science team picked up a big surprise that could have been a serious problem, but turned out all right in the end. When they tried to extract the drill from the hole, the drill instead stayed stuck to the rock, and picked the whole rock up instead.

The four images to the right show the sequence, sourced from here, here, here, and here.

On April 25, 2026, Curiosity drilled a sample from a rock nicknamed “Atacama,” which is an estimated 1.5 feet in diameter at its base, 6 inches thick and weighs roughly 28.6 pounds (13 kilograms). When the rover retracted its arm, the entire rock lifted out of the ground, suspended by the fixed sleeve that surrounds the rotating drill bit. Drilling has fractured or separated the upper layers of rocks in the past, but a rock has never remained attached to the drill sleeve. The team initially tried vibrating the drill to shake off the rock, but saw no change.

Then, on April 29, they tried reorienting Curiosity’s robotic arm and vibrating the drill again. Imagery in the GIF shows sand falling from Atacama, but the rock stayed attached to the rover.

Finally, on May 1, Curiosity’s team tried again, tilting the drill more, rotating and vibrating the drill, and spinning the drill bit. The team planned to perform these actions multiple times but the rock came off on the first round, fracturing as it hit the ground.

Had they not been able to release the rock it could have seriously impacted the mission, even ended it.

As noted by the science team in their own update today about this situation:

Future activities involve wrapping up the drill campaign on Atacama and, nominally, seeking a more firmly rooted drill target in order to collect drill tailings for analysis, which were lost from Atacama as part of the effort to dislodge the drill bit from the rock.

In other words, they are going to have hunt around for a better drill spot, as they really do want to study some drill samples at this location. They have left the boxwork area and have moved uphill closer to the pure sulfite unit, and want to see how the geology has changed.

The UK’s Sutherland spaceport now appears dead

9:45 am

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

In a news report yesterday about the failure of the United Kingdom’s rocket startup Orbex in February 2026, the following details about the Sutherland spaceport in Scotland suggests that spaceport is now defunct, with little chance of being revived.

Administrators say that one of Orbex’s key remaining assets is the Sutherland Spaceport site near Melness – although the only construction work undertaken at the site is some 600m of access road. The company responsible for it, Sutherland Spaceport Ltd (SSL), remains financially stable, according to administrators. This means the site could still be sold or potentially restarted, even though no launch activity is currently taking place.

The spaceport sits on land leased from local crofters under a long-term arrangement managed through Highlands and Islands Enterprise. SSL holds a 50-year sublease, with an option to extend for 25 years, and a break clause in 2027.

Orbex had originally intended to launch from Sutherland — close to the rocket factory it had built — but local opposition by billionaire Anders Holch Povlsen (who is a major owner in the competing Saxavord spaceport on the Shetland Islands) as well as endless bureaucratic delays from the UK’s Civil Aviation Authority made that impossible. The company attempted to switch its launches to Saxavord, but the cost and new licensing requirements were too much.

No other launch company has expressed any interest in using Sutherland, and it appears none will be forthcoming in the near future. The red tape in the UK, combined with that powerful local opposition, has made Sutherland a pariah to the smallsat rocket companies looking for launch sites.

Though the spaceport might say it is “financially stable”, without any customers I guarantee it is going to disappear at some point.

Conscious Choice cover

Now available in hardback and paperback as well as ebook!

 

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.

 
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.  
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.

 

“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of the Mars Society.

 

All editions are available at Amazon, Barnes & Noble, and all book vendors, with the ebook priced at $5.99 before discount. All editions can also be purchased direct from the ebook publisher, ebookit, in which case you don't support the big tech companies and the author gets a bigger cut much sooner.

 

Autographed printed copies are also available at discount directly from the author (hardback $29.95; paperback $14.95; Shipping cost for either: $6.00). Just send an email to zimmerman @ nasw dot org.

Former NASA administrator Bridenstine moves from lobbyist to CEO of orbital tug startup

9:29 am

Jim Bridenstine
Jim Bridenstine testifying before Congress
as a big space lobbyist

Former NASA administrator Jim Bridenstine has taken the job of CEO for the orbital tug startup Quantum, ending his post-NASA career as a lobbyist for some of the biggest old space companies.

Since his departure from NASA, Bridenstine has worked as a managing partner of The Artemis Group consulting firm, and the appointment to Quantum Space marks the first time he has taken up an official corporate post, he told Breaking Defense.

“I was asked several times” to be a CEO, he said, but “never accepted until now.”

Bridenstine waxed enthusiastic about Quantum Space’s plans for its Ranger spacecraft that is being designed to support “sustained maneuver for dynamic space operations.”

Bridenstine’s lobbying for the Artemis Group was mostly aimed at encouraging a giant NASA space program, comparable to the 1960s Apollo effort, with the main beneficiaries the older established companies like Boeing, Lockheed Martin, and Northrop Grumman, and at the expense of the new space industry led by SpaceX. That effort was largely a failure, as it has become very clear these old companies can’t get the job done, at least not at a price anyone can afford.

At Quantum Bridenstine is back on the side of new space, pushing a new orbital tug company whose Ranger tug can “carry a whopping 4,000 kilograms (8,818.49 pounds) of hydrazine fuel to orbit, Bridenstine explained, and will use that fuel for both chemical propulsion and electric propulsion.” It plans on launching the first Ranger demo mission in early 2027, after which the company hopes to win both commercial and military contracts using Ranger’s tug capabilities.

Two lawsuits against SpaceX, claiming company operations damage local homes

9:26 am

Starship and Superheavy during ascent
Starship and Superheavy ascending during October test flight.

SEE UPDATE BELOW for info on 2nd lawsuit.
—————————-
In what appears to be another frivolous lawsuit aimed at SpaceX, about 80 homeowners located from five to ten miles away from SpaceX’s Starbase launch site at Boca Chica have now sued the company, claiming Starship launches have damaged their homes.

The 53 homes are in small towns between 5 and 10 miles from SpaceX’s launch complex near Boca Chica Beach outside Brownsville with 43 in Port Isabel and the others in Laguna Vista, Laguna Heights and South Padre Island.

The lawsuit doesn’t describe the specific damage incurred by each homeowner, but there have been reports of houses shaking, items falling off shelves and broken windows after previous launches and landings of Starship, the world’s largest and most powerful rocket.

“SpaceX has repeatedly subjected the surrounding areas to extraordinary amounts of acoustic energy including noise, vibrations, and sonic booms,” it said of the flights, which can produce multiple sonic booms in addition to the sustained noise of launch, depending on the mission. Starship operations have subjected the plaintiffs’ homes “to repeated intense and damaging acoustic events,” the lawsuit said. [emphasis mine]

In other words, the launches are noisy, and might have caused some things to fall off shelves and might have broken windows. Note too that in Florida the safety zone around launches is three miles, and comparable rockets to Superheavy/Starship (Saturn-1B, Saturn-5, the Space Shuttle and SLS) have repeatedly launched there without causing any noticeable damage. I myself watched a shuttle launch from five miles away and found the sound of the launch actually disappointing. It certainly wasn’t going to cause damage to anything at that distance.

This lawsuit therefore appears simply to be a case of some lawyer trying to blackmail a big company for some ready cash. Its origin might also stem from the insane leftwing hate of Musk because he had to gall to support the election of Donald Trump in 2024. Note too that the author of the article at the link, Brandon Lingle, seems to be one of those insane anti-Musk haters, as he never has anything good to say about SpaceX, and treats all environmentalists like saints.

UPDATE: It appears the same law firm behind the lawsuit above has filed a second lawsuit for 80 other landowners in the vicinity of SpaceX’s MacGregor test site near Waco, claiming the static fire engine tests there are causing them unspecified problems as well. As with the lawsuit above, it appears the claims are mostly an attempt to squeeze money from SpaceX, with some of that effort fueled by anti-Musk hatred.

Lockheed Martin joins partnership to build off-shore launch platform

9:01 am

According to a post yesterday by Johnathon Caldwell, a vice president and general manager at Lockheed Martin, the company will be joining the partnership of Seagate and Firefly to build an off-shore launch platform from which Firefly hopes to launch its Alpha rocket.

The three companies will work together on mission‑application concepts and flight‑demonstration projects that leverage Seagate’s Gateway offshore launch platform. This sea‑based launch facility, combined with Firefly’s responsive Alpha launch vehicle, will provide rapid, flexible access to space from diverse locations, an essential capability for tactical payloads and national‑security missions.

Seagate only went public with this project in late March. Firefly signed on in April. Now Lockheed Martin has joined. It appears the concept has great potential for it to attract so much interest so quickly. Nor should this be surprising. The Chinese have been very successful in the past two years with its own sea platform, and the concept was proven years ago with Sea Launch.

Though Firefly presently launches Alpha from Vandenberg, the company also has deals with Sweden’s Esrange spaceport and a lease for a pad at Cape Canaveral. It has also been studying launching from a proposed commercial spaceport in northern Japan. This partnership with Seagate might allow it to abandon all these land-based sites, or supplement them.

Lockheed Martin in the past has invested heavily in new rocket companies, including Rocket Lab, ABL, Orbex, and X-Bow. Of these, only Rocket Lab has succeeded. With this deal Lockheed is looking for another option for getting its commercial and military payloads into orbit, with a much greater launch flexibility.

Malta signs Artemis Accords

8:33 am

On the same day (May 4th) Ireland officially signed the Artemis Accords (as announced on May 1st), Malta also signed the accords, becoming the 66th nation to join this American space alliance.

The Republic of Malta became the 65th signatory to the Artemis Accords on Monday during a ceremony in the town of Kalkara with NASA and U.S. Department of State officials present. … Malta’s Minister for Education, Youth, Sports, Research and Innovation Clifton Grima signed the Artemis Accords on behalf of the country. … U.S. Ambassador to Malta Somers W. Farkas and NASA Europe Representative Gregory Mann witnessed the signing together with Deputy Prime Minister and Minister for Foreign Affairs and Tourism Ian Borg.

As I predicted on April 30th, the success of the Artemis-2 mission has caused a lot of third world smaller nations to quickly jump on the bandwagon, with Latvia, Jordan, Morocco, Ireland, and now Malta all signing in just the past week.

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, Malta, 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.

Expect more nations to sign on in the coming weeks.

Blue Origin’s 1st unmanned lunar lander completes ground testing

8:01 am

Blue Origin’s 1st unmanned lunar lander, dubbed Blue Moon Mark-1 (MK-1) or “Endurance,” has completed ground testing at the Johnson Space Center in Houston, prior to its planned launch before the end of this year.

The NASA press release however said nothing about the results of that testing.

Testing in NASA Johnson’s Chamber A, one of the world’s largest thermal vacuum test facilities, enabled engineers to model the vacuum of space and the extreme temperature conditions the spacecraft would experience during flight. By recreating these conditions on the ground, teams evaluated system performance and verified structural and thermal integrity prior to launch. NASA and Blue Origin will incorporate lessons learned from MK1’s design, integration, and testing to support NASA’s future Artemis missions that will return American astronauts to the Moon.

Normally when such testing is completed the press release touts their success. The vagueness in the language above is to my instincts somewhat concerning. Did they find something in that testing that needs modification prior to launch? If so, getting this lander off the ground before the end of the year is going to be questionable, as those fixes will have to be incorporated and then tested again.

Any delay such as this would in turn impact the first test in orbit of Blue Origin’s manned Blue Moon MK-2 lunar lander, scheduled for late 2027 during the Artemis-3 manned mission, where NASA wishes to test rendezvous and docking for both Blue Origin’s lander and SpaceX’s Starship.

Some clarity here would be reassuring.

Sunspot update: The number of sunspot continues to decline

9:21 am

For only the second time since I started this website in 2010, I forgot last month to do my monthly sunspot update. No matter. The Sun’s behavior in producing sunspots in the past two months was actually amazingly similar, so doing both months at once works.

According to NOAA’s monthly graph of the sunspot activity on the Earth-facing hemisphere, the amount of sunspots in both March and April continued to be low, well below the predictions put forth by NOAA’s panel of scientists in their April 2025 prediction.

That graph is below, annotated with extra information by me to illustrate the larger scientific context.

China imposes extensive regulations on its pseudo-commercial space industry

8:01 am

China's communists to its citizens
China’s communists to its citizens “Nice business you got here.
Shame if something happened to it.”

As I predicted when China announced in the fall 2025 that it was creating a special agency to supervise the pseudo-companies in its faux commercial space industry, the Chinese government last week announced the release of what it calls its “Commercial spaceflight standards system,” covering all aspects of the operations its pseudo-private companies.

The standards cover six different areas, but the first best expresses the government’s overall goal:

‘Industry Governance Standards’ focuses on the sector’s characteristics of rapid development, agile response, and short delivery times, alongside space safety concerns such as debris mitigation and protection. With subcategories including market access, safety supervision, space environment governance, certification, energy conservation, and occupational health, it is intended to establish hard regulatory constraints as the compliance foundation for orderly commercial space development. [emphasis mine]

The screen capture from a Monty Python skit to the right says it all. The communists running China apparently did not like the chaotic free nature of this pseudo-industry, with the different companies coming up with many wild and innovative ideas, some of which were bound to fail. The communists also saw that some of these pseudo-companies were also making a lot of money that the communists weren’t getting.

And so, the government formed this agency, and it called the companies together to lay down the law.

Is SpaceX buying a 200-plus square mile patch of Louisiana?

11:20 am

Pecan Island SpaceX facility?

According to a real estate agent in Louisiana, there is credible but unconfirmed evidence that SpaceX is in the process of buying a 136,000 acre plot of land owned by Exxon on the coast of Louisiana west of New Orleans, near the unincorporated town of Pecan Island.

The rumor — repeated in private group chats, in coffee shops in Abbeville, and in hunting camps from Forked Island to Grand Chenier — is that SpaceX has acquired or is in the process of acquiring approximately 136,000 acres of coastal Louisiana marshland straddling Pecan Island and Freshwater City in Vermilion Parish. The footprint reportedly stretches from south of Highway 82 down to the Gulf of America, encompassing some of the most ecologically rich and economically untouched wetlands in North America.

If true, this would be the single largest private land acquisition in the modern history of Vermilion Parish. To put it in perspective: 136,000 acres is roughly 212 square miles — bigger than the entire city of New Orleans. SpaceX’s existing Boca Chica/Starbase facility in South Texas, which has reshaped Brownsville’s economy and real estate market in just five years, is built on a footprint of less than 100 acres. A 136,000-acre Louisiana site would not be a launch pad. It would be an industrial campus on a scale never before seen in American aerospace.

I must emphasize that this agent is speculating, and that there is no confirmed evidence that SpaceX is the rumored buyer. At the same time, the agent has done his homework. This purchase by SpaceX would make sense on multiple levels. It would give it a very large facility smack dab between Boca Chica and Florida, on the Gulf, so that if Starships are manufactured here they could be easily shipped both east and west to those launch sites. This facility would also give SpaceX to option of shifting more of its operations out of unfriendly California and to a more friendly state, something Elon Musk has been doing since the Covid panic.

It would allow for the construction of larger data centers and satellite manufacturing factories, without much opposition from local communities.

Finally, there is the possibility this location could also serve as a spaceport, though it would only work well for polar orbits.

Stay tuned. If this speculation is true we should find out momentarily.

$2 bill that Gene Cernan carried on three missions sells for more than $90K

3:23 pm

The $2 bill that astronaut Gene Cernan carried on all three of his space missions in 60s and 70s has now sold at auction for $91,519.

Signed and flight-certified by Cernan, the bill is encapsulated and graded by Paper Money Guaranty (PMG) as Choice Fine 15. The holder notes its provenance as having been flown aboard Gemini 9A (1966), Apollo 10 (1969), and Apollo 17 (1972), and traces its origin to Cernan’s personal collection.

A signed letter of provenance from Cernan states that the bill was originally owned by his father and later carried by the astronaut on each of his spaceflights. The letter documents its presence during low Earth orbit on Gemini 9A, lunar orbit on Apollo 10, and on the lunar surface during Apollo 17.

This auction was space-focused and realized a total of $1,764,603. It included items from a number of other Gemini and Apollo missions, including an American flag that astronaut Dave Scott flew on Gemini 8, the mission that achieved the first docking in space but then had to due an emergency splashdown because a thruster began firing uncontrollably. It sold for $47,406.

No Starliner mission to ISS this year

3:07 pm

Though in February 2026 NASA officials suggested there might be a Starliner cargo mission to ISS sometime in April 2026, the new schedule released today for ISS manned and cargo missions for the rest of this year shows no Starliner missions at all.

The press release hinted an extra Starliner mission could be added, but don’t but too much faith in this:

Launch opportunities for NASA’s uncrewed Boeing Starliner-1 cargo mission remain under review as teams continue working through technical issues discovered during the Crew Flight Test in 2024, as well as final actions from the Program Investigation Team report. The agency is assessing operational readiness and space station traffic to determine the earliest feasible launch window.

What I think is happening in NASA is that the agency under Isaacman wants a better assurance from Boeing that the problems with Starliner have been fixed, and Boeing is having trouble satisfying them. If so, it seems he is doing what I suggested in February, demand from Boeing the highest quality work or don’t buy anything from it at all. If so kudos to Isaacman.

It is also possible Isaacman doesn’t want to spend extra money paying Boeing for this extra cargo mission to prove out Starliner’s systems. Boeing’s contract for Starliner is fixed price, and the capsule’s multiple problems has now cost the company more than a billion dollars. It is unlikely it will have make a profit on it, which is why it wants NASA to pay for that cargo flight.

Either way, the first operational manned mission using Starliner continues to recede into the future, to the point where ISS might be gone before the capsule is finally okayed for manned flights.

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

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.
