Canadian rocket startup Nordspace obtains expanded ground station contract

Proposed Canadian spaceports

The Canadian rocket startup Nordspace has signed an agreement with the ground station company C-Core to establish more tracking and communication facilities in conjunction with Nordspace’s launch plans at its Atlantic spaceport in Newfoundland.

NordSpace and C-CORE have signed a Memorandum of Understanding (MOU) that will see the companies work together in developing new ground stations across Canada with initial locations planned for the Atlantic Spaceport Complex (ASX) in St. Lawrence, Newfoundland and Labrador, and Inuvik, Northwest Territories.

With C-CORE being based in St. John’s, Newfoundland, and already established in providing ground station services, it seems like a natural collaboration that could benefit both companies. For NordSpace, which owns and is developing the Atlantic Spaceport Complex, this collaboration provides the potential for another type of revenue source as the company tries to diversify.

Nordspace has not yet launched, though its first suborbital test launch several weeks ago was scrubbed twice due to ground equipment fuel leaks. It has not yet announced another date for that suborbital test, but plans a static fire test in October of the engine it is building for its orbital Tundra rocket.

This company is only three years old, and appears to have leap-frogged past Canada’s other spaceport operation in Nova Scotia, which has been trying to get off the ground for almost a decade.

Stoke Space said to be raising as much as $500 million in private investment capital

9:17 am

Stoke's Nova rocket
Stoke’s Nova rocket, designed to be
completely reusable.

UPDATE: Stoke Space confirms the story, announcing today that it has raised $510 million in new capital.

According to anonymous sources, the rocket startup Stoke Space is in the process of raising as much as $500 million in private investment capital, with new $2 billion valuation for the company.

Stoke Space, one of the Seattle area’s up-and-coming space startups, is said to be raising hundreds of millions of dollars in a funding round that it hasn’t yet publicly acknowledged. A report about the round, based on two unidentified sources, was published today by The Information.

The Information quoted its sources as saying that the funding round could total as much as $500 million, and would value Stoke at nearly $2 billion. That figure would be roughly twice as much as the $944 million valuation that was cited by Pitchbook as of January. The round’s lead investor is said to be Thomas Tull’s United States Innovative Technology Fund.

Earlier this year Stoke raised $260 million, bringing its available capital to almost a half billion. If this story is confirmed, it means the company will have almost a billion in available cash on hand.

The design of Stoke’s Nova rocket is unique in that both the lower and upper stages will be reusable. The first stage will land vertically, like SpaceX’s Falcon 9. The upper stage meanwhile uses a radical nozzle design, a ring of tiny nozzles around the perimeter of a heat shield, to protect it during re-entry.

The company has said it plans the first launch in 2026, but has not been more specific as to when. If successful, this rocket will certainly become a major player, as it will be able to offer even lower prices than SpaceX because none of the rocket will be expendable.

SpaceX launches 28 Starlink satellites, reuses 1st stage for 29th time

8:31 am

SpaceX last night successfully launched another 28 Starlink satellites, its Falcon 9 rocket lifting off from Vandenberg Space Force Base in California.

The first stage, B1071, completed its 29th flight, landing on a drone ship in the Pacific. The present rankings for the most reflights of a rocket:

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

Sources here and here.

Note also that SpaceX was able to refly this stage only 24 days after its previous flight. Even after 28 flights, the booster appears so robust the company can get it back in the air only weeks later.

The leaders in the 2025 launch race:

129 SpaceX
58 China
13 Russia
12 Rocket Lab

SpaceX now leads the rest of the world in successful launches, 129 to 98. SpaceX has another launch scheduled for this evening, placing another set of Amazon’s Kuiper satellites into orbit.

Japanese satellite company extends its launch contract with Rocket Lab

8:01 am

The Japanese satellite company Q-shu Pioneers of Space, Inc. (iQPS) has purchased three more launches from Rocket Lab, for a total of seven planned.

The multi-launch contract includes three dedicated Electron missions that will launch no earlier than 2026 from Rocket Lab Launch Complex 1 in New Zealand. With four dedicated missions already booked by iQPS on Electron, these three additional missions bring the total number of upcoming launches for iQPS to seven.

Each dedicated launch will deploy a single synthetic aperture radar (SAR) satellite from a Rocket Lab Motorized Lightband separation system – demonstrating Rocket Lab’s vertical integration across launch and space systems that improves reliability and streamlines the launch process for its customers.

Rocket Lab has already completed four successful launches for iOPS, so with this deal means that it will complete eleven launches total for the satellite company. Essentially iQPS has made Rocket Lab its prime launch provider.

This is also the second major launch contract for Rocket Lab in the past week. On September 30, 2025 Synspective purchased its second multi-launch contract with the company, buying ten more launches. Its first contract was for eleven launches, with six already completed. Synspective hopes to have its entire radar constellation of 30 satellites in orbit by the late 2020s.

Both contracts tell us that Rocket Lab’s Electron rocket is going to have a very busy launch schedule for the next few years, even as the company initiates its larger Neutron rocket.

Is the fate of the independent live streams in Boca Chica uncertain?

12:52 pm

My headline paraphrases this interesting, very detailed, and largely accurate article today from Texas Monthly. It outlines how the newly formed town of Starbase there has the power to block the many independent lives streams and tourist operations that have sprung up since SpaceX opened its facility in Boca Chica.

This proxy government also has the power to create zoning rules and enforce them. In July the city adopted a plan that leaves those with the closest views of the launchpads in violation of new zoning designations. The mainstay launch-day ticket sellers here—Rocket Ranch and a few others—operate in what’s now officially a residential area, near newly built homes for SpaceX executives. The same violation applies to the spots where the streamers have mounted their video cameras.

These cottage industries aren’t doomed. Texas law has grandfathering provisions that allow existing businesses to remain open after zoning changes. But Starbase city attorney Andy Messer raised eyebrows during a recent city commission meeting by saying that the grandfathering would be considered on a “case-by-case basis.” Hearing this, some property owners expressed hesitation to approach the city to ask if their status was in question. “I don’t want to poke the bear,” as one put it.

Will SpaceX force the town of Starbase to shut these independent operations down? The article describes the possibilities in great detail. The very nature of SpaceX and its founder, Elon Musk, suggests it won’t happen. The company thrives on openness and straight talk. Musk himself is a proven supporter of free speech and competition. It would be shocking if his company suddenly took a different position. Moreover, SpaceX, Starbase, or its residents (almost all of which are SpaceX employees) generally benefit from the good publicity of these independent operations, publicity that the company’s own employees enjoy.

Yet, Starbase is a company town, and the long history of such places is that with time, the company takes over and rules everything, allowing nothing that it does not control.

Stay tuned. Above all things won’t be dull in Boca Chica.

Martian boxwork on the flanks of Mount Sharp

The boxwork on Mars
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on October 5, 2025 by the left navigation camera on the Mars rover Curiosity.

The picture looks north and downhill from the lower flanks of Mount Sharp, inside Gale Crater. In the far distance on the horizon can be seen the crater’s northern rim, about 20 to 30 miles away. As it is now moving into the dusty season on Mars, the haze has increased from only a month ago, making it hard to see many distant details.

In the foreground can be seen clearly the light-colored ridges of the boxwork that the rover has been traversing for the past three months, with one rover track visible on the nearest ridge. Unlike the very rocky and boulder-strewn terrain the rover has seen in most of its travels on Mount Sharp, this boxwork seems smoother.

The Juno mission at Jupiter is almost certainly over

8:52 am

An article yesterday at Space.com speculated that the Juno mission to Jupiter is likely over, but added that we cannot yet be sure because the government shutdown has prevented NASA from making any definitive announcement.

NASA’s management had previously extended the orbiter’s mission several times, with the last extension going until the end of the 2025 fiscal year, that ended on September 30, 2025. No new budget has yet been approved, and the proposed Trump budget had included no money for extending the mission farther.

Due to the government shutdown, NASA is currently unable to say whether Juno is still operating or already powered down. At the time of publication, responses from agency officials state that “NASA is currently closed due to a lapse in government funding … Please reach back out after an appropriation or continuing resolution is approved.”

Under shutdown rules, only missions that fall under “excepted activities” — those required to protect life, property, or national security — can continue operations or communications. NASA’s continuity plans also specify that carryover funding may only be applied to “presidential priorities,” which limits what science programs can proceed during a lapse.

Juno does not fall into those protected categories, and was also zeroed-out on the President’s fiscal year 2026 budget request — making the mission, presumably, not a priority. So, until normal government operations resume, the spacecraft’s future is uncertain.

I think Juno’s future at this point is not uncertain in the least. While other active missions that the Trump proposed shutting down might get revived, Juno is unlikely to be one of them. I suspect the science team has put it in hibernation, and is already beginning to move on to other projects and work. They are being coy about this in the faint hope Congress will save Juno, but this should not be a priority. At this point I think NASA would be wiser to spend its resources elsewhere.

A galaxy with a starburst ring within its nucleus

A galaxy with a starburst ring
Click for full image.

Cool image time! The picture to the right, cropped, reduced, sharpened, and annotated to post here, was released today by the science team of the Hubble Space Telescope as the picture of the week. This crop focuses on the central regions of this barred spiral galaxy, about 70 million light years away, with an unusual extra feature, a starburst ring encircling its nucleus. From the caption:

NGC 6951’s bar may be responsible for another remarkable feature: a white-blue ring that encloses the very heart of the galaxy. This is called a circumnuclear starburst ring — essentially, a circle of enhanced star formation around the nucleus of a galaxy. The bar funnels gas toward the centre of the galaxy, where it collects in a ring about 3800 light-years across. Two dark dust lanes that run parallel to the bar mark the points where gas from the bar enters the ring.

The dense gas of a circumnuclear starburst ring is the perfect environment to churn out an impressive number of stars. Using data from Hubble, astronomers have identified more than 80 potential star clusters within NGC 6951’s ring. Many of the stars formed less than 100 million years ago, but the ring itself is longer-lived, potentially having existed for 1–1.5 billion years.

This galaxy has also seen about a half dozen supernova, which raises the question: Does intense star formation trigger more supernovae? That is a question that can’t be answered with the data presently available.

ESA looks to global private sector for its next ISS cargo mission

10:13 am

ESA logo

The European Space Agency (ESA) has issued a request for bids to launch a cargo mission to ISS by the fourth quarter of 2028, and its request will allow companies other than those in Europe to bid.

Published on 3 October, the call for the CSOC Cargo Commercially Procured Offset initiative outlines a single mission to transport 4,900 to 5,000 kilograms of pressurised cargo to the ISS.

… In the call’s “Letter of Invitation”, the agency stated that, due to regulatory requirements that include certifications provided by NASA, the competition would be open to economic operators from the United States. ESA did, however, add that preference would be given, to the “fullest extent possible”, to bids from its Member States.

While the call is set to close on 31 October, the execution of the mission’s procurement will only move forward if the necessary funding is approved by Member States at ESA’s Ministerial Council meeting in November. It will then need to be approved by the relevant Programme Board and the Industrial Policy Committee.

Though there are several European startups (The Exploration Company, Thales Alena, Atmos, PLD) now developing unmanned returnable capsules that will eventually be able to bring cargo to and from ISS, none appear likely to be able to meet the 2028 deadline. Thus, the most likely winner of this contract will be SpaceX.

More significant is the nature of ESA’s request. In the past the agency simply built and owned its own cargo capsule, the ATV. Rather than build another, it is adopting the capitalism model, asking its private sector to make it happen.

Firefly Aerospace buys defense contractor SciTec

9:21 am

Firefly Aerospace yesterday announced that it is buying the defense contractor SciTec for $300 million in cash plus $555 million in Firefly shares.

The shares go to SciTec’s owners at an agreed-to value of $50 per share, essentially making those individuals part owners of Firefly.

The acquisition will advance Firefly’s comprehensive space services by adding mission-proven defense software analytics, remote sensing, and multi-phenomenology data expertise. SciTec’s core capabilities – which include missile warning, tracking and defense, intelligence, surveillance and reconnaissance, space domain awareness, and autonomous command and control – will supplement Firefly’s launch, lunar, and in-space services. SciTec further adds ground and onboard data processing as well as AI-enabled systems designed for low latency operations to support advanced threat tracking and response across multiple domains.

In other words, this acquisition is aimed at improving Firefly’s ability to win defense contracts, thus diversifying its business beyond outer space. This suggests its managers believe there isn’t enough business in outer space to put the company in the black. It needs defense contracts, and adding SciTech increases the odds it will win those contracts.

The stock price in this sale, $50, I think tells us something of the motives of SciTec’s owners. At present Firefly’s stock is selling at about $30 on Wall Street, and the price has not changed much today after this announcement. It appears the stock obtained by SciTec’s owners is thus not as valuable as listed in the intended sale price. This in turn suggests that those owners also needed this deal to diversify the company, and were willing to take a loss in the value of their stock to get it.

Then again, my understanding of how Wall Street and stocks function is limited, and my analysis on this point could be completely wrong.

Space Force awards SpaceX and ULA seven launches worth more than a billion dollars

3:05 pm

The U.S. Space Force (USSF) yesterday awarded multi-launch contracts to both SpaceX and ULA for seven launches beginning in 2027 worth more than a billion dollars.

SpaceX received $714 million for five launches and ULA was awarded $428 million for two launches, USSF said in an Oct. 3 news release.

The awards are part of the Space Force’s National Security Space Launch Program, which it uses to launch services for military space missions. In April, it chose SpaceX, ULA, and Blue Origin to launch a total of 54 missions scheduled between fiscal 2027 and 2032, with SpaceX responsible for just over half, with 28 launches. Individual missions will be awarded in batches through fiscal 2029.

Though Blue Origin was included in this program and its New Glenn rocket has finally launched once successfully, its not yet been certified to launch military satellites, and to get certified the company is going to have to launch at least one more time. That launch is expected before this month is out. Moreover, it will soon have to compete against more companies, and the Pentagon will be adding Rocket Lab and Stoke Space to its approved list as soon as both successfully launch their respective Neutron and Nova rockets by next year.

Gilmour to attempt first launch again next year

2:53 pm

Eris rocket launch and failure

(indicated by red dot). Click for video, cued
to just before launch.

According to a presentation by the CEO and founder of Australian rocket startup Gilmour Space, the company now sufficiently understands what caused the failure on its first launch attempt on July 30 to plan a second attempt in 2026.

The company is still investigating the root cause of the failure. “It looks like what went wrong on the launch is something we’ve never tested close enough to the launch conditions before,” he said, but didn’t elaborate.

One factor in the launch was the long delay between shipping the rocket to the launch site, known as the Bowen Orbital Spaceport, and the launch itself. “Rockets aren’t designed to be at the launch site for 18 months,” he said. The launch site, he noted, is just a kilometer from the ocean, creating salty conditions that can be corrosive.

That extended time at the launch site stemmed from delays securing regulatory approvals for the launch. That included not just a launch license from the Australian Space Agency but also airspace, maritime and environmental permits. “We had to get 24 different permits from the Queensland government,” Gilmour said. “All of these things take a long time to do.” He acknowledged that the company had not put enough resources into those regulatory processes. “The approval processes just took way too long.”

What is ironic is that as bad as Australia appears to be in terms of red tape, it is far better that it mother country, Great Britain. At least in Australia spaceports have been approved and at least one launch has taken place. And it only took eighteen months! In Great Britain the permitting process for its two proposed rocket spaceports has taken almost a decade, and still no vertical launches have occurred at either.

Satellite propulsion startup Portal successfully tests new and radical thruster design

10:32 am

The satellite propulsion startup Portal has become the first commercial company to test successfully a thruster that uses concentrated sunlight to ionize a fuel.

The concept has been studied several times by NASA and other government entities, but never tested to a point where it could be used on a mission. According to this report:

For the vacuum chamber test at Portal’s Bothell lab, engineers used an electrical induction system to simulate the sun’s heating power. The apparatus reached temperatures in the range of 1,500 degrees Celsius (2,700 degrees Fahrenheit), and the performance of the thruster validated Portal’s propulsion architecture for integration with future flight hardware.

The concept is similar to an ion engine, but appears to produce more thrust, allowing it to move satellites more quickly to different orbits. Portal hopes to do an in orbitat test by next year. The company has raised $17.5 million in private funding, and $45 million from an Air Force grant.

Update on the plans to observe interstellar Comet 3I/Atlas using interplanetary spacecraft

10:16 am

Link here. The key take-away is that nothing is being repurposed to attempt to fly to Comet 3I/Atlas. Instead, as expected the science teams for all the Mars orbiters will turn their instruments to the comet when it is at its closest point to Mars, about 19 million miles away.

Don’t expect any Earth-shattering revelations:

The cameras on these spacecraft were designed to photograph the surface of Mars from Mars orbit, and won’t be able to pick out much detail on such a relatively small comet 30 million km away. But the cameras may be able to capture images of its long tail and also gather data that scientists can use to find out more about what 3I/ATLAS is made of.

Some spectroscopic data will be obtained, but it likely will not be much better than what Webb and other Earth-based telescopes have gotten already.

Similarly, the science team for Europe’s Juice mission, on its way to Jupiter, will take a look, but the distances and orbital positioning will likely limit what it can detect as well.

The growing mystery of the little red dots in the early universe

12:09 pm

The uncertainty of science: A review of the population of what scientists call “Little Red Dots” (LRDs) — discovered in the early universe by the Webb Space Telescope — has found that 30% do not appear to be compact objects when viewed in ultraviolet wavelengths.

The team studied 99 LRDs, and found that about 30% are not simply compact dots when observed in the ultraviolet.Instead, they reveal disturbed or clumpy structures, in stark contrast to their smooth, point-like appearance at optical wavelengths. Because these galaxies are so far away, their optical light is stretched, or “redshifted,” into the long-wavelength channel of JWST, where the resolution is not sharp enough to see structure, so they look like simple dots.

Rinaldi: ‘But their ultraviolet light is shifted into JWST’s short-wavelength channel, where the telescope has much finer resolution, and there we suddenly see clumps, asymmetries, and signs of interaction. On top of this, in the spectra of some of our LRDs we directly detect the fingerprints of active black holes, with gas moving at thousands of kilometres per second.’ This shows that at least part of this population is powered by growing black holes, while others seem to be dominated by star formation, making LRDs a mixed and diverse family of sources. This is a crucial clue, suggesting that mergers and galaxy interactions may be the trigger for the “LRD phase”.

In other words, astronomers don’t really know what these dots are at present. If some are supermassive black holes, this poses a problem for Big Bang cosmology, as there should not have been enough time since the Big Bang for these black holes to have formed.

That 70% still appear to be compact single objects might mean that’s what they are, but it could also mean that our present observations tools don’t yet have the ability to resolve them.

Analysis of archived Cassini data finds a new slate of carbon-based molecules in the plumes of Enceladus

10:38 am

Enceladus at 77 miles

from 77 miles during 2015 fly-by. Resolution is
50 feet per pixel.

A new analysis of the archived Cassini data taken when the spacecraft flew through the plumes of the Saturn moon Enceladus in 2008 has revealed a number of new organic molecules (not life but carbon-based) that suggest the chemistry of the moon of Saturn is far more complex that expected.

You can read the paper here. From the abstract:

Here we present a comprehensive chemical analysis of organic-bearing ice grains sampled directly from the plume during a Cassini fly-by of Enceladus (E5) at an encounter speed of nearly 18 km [per second]. We again detect aryl and oxygen moieties in these fresh ice grains, as previously identified in older E-ring grains. Furthermore, the unprecedented high encounter speed revealed previously unobserved molecular fragments in Cosmic Dust Analyzer spectra, allowing the identification of aliphatic, (hetero)cyclic ester/alkenes, ethers/ethyl and, tentatively, N- and O-bearing compounds. These freshly ejected species are derived from the Enceladus subsurface, hinting at a hydrothermal origin and involvement in geochemical pathways towards the synthesis and evolution of organics.

In other words, this data further suggests there exists an underground ocean inside Enceladus, and that ocean has a lot of complex organic chemistry energized by the planet’s internal heat and the tidal forces imposed by Saturn’s gravity.

This is not the first time scientists have reviewed archived Cassini data of these plumes and found new molecules. It is simply a closer look at earlier analyses in 2018 and 2019.

This data has not discovered life, but it suggests that life is certainly possible within that proposed underground ocean. At a minimum, the chemistry there will be very complex and alien.

Astronomers snap picture of a baby exoplanet

Baby planet
Click for original image.

Cool image time! The picture to the right, cropped to post here, was taken using Magellan Telescope in Chile and the Large Binocular Telescope in Arizona. The exoplanet is the small purple dot to the right of the star and the accretion ring that surrounds it.

This exoplanet is very young, only about five million years old, and is thus still accumulating material. Even so, its mass is presently estimated to be five times that of Jupiter.

Following [the first] observations of the system, researchers looked at WISPIT 2, and spotted the planet WISPIT 2b for the first time, using the University of Arizona’s MagAO-X extreme adaptive optics system, a high-contrast exoplanet imager at the Magellan 2 (Clay) Telescope at Las Campanas Observatory in Chile. This technology adds another unique layer to this discovery. The MagAO-X instrument captures direct images, so it didn’t just detect WISPIT 2b, it essentially captured a photograph of the protoplanet.

…In addition to discovering WISPIT 2b, this team spotted a second dot in one of the other dark ring gaps even closer to the star WISPIT 2. This second dot has been identified as another candidate planet that will likely be investigated in future studies of the system.

You can read the paper here [pdf]. The other candidate exoplanet is the bright spot below the star, inside the ring.

The technology of astronomy continues to advance.

International Astronautical Congress meeting in Australia produces several international agreements

9:40 am

During the International Astronautical Congress meeting that is going on in Sydney, Australia this week, a number of countries have signed agreements calling for a variety of partnerships.

None of the agreements appear to include any significant new projects. All suggest a desire to work together to foster development in their commercial space industries. The number of agreements with Australia is a reflection of the conference’s location in Sidney.

The most amusing agreement is the last, between the UK and Australia. The governments of both of these Commonwealth nations have had serious problems with red tape that have hindered commercial development, especially in the UK. The agreement expands a UK government grant program worth about $9 million so that Australian startups can win grants. It apparently does nothing to ease the red tape in either nation.

Varda signs deal for more capsule landings in Australia

9:10 am

Proposed Australian spaceports
Australian spaceports: operating (red dot) and proposed (red “X”)
Click for original image.

The recoverable capsule company Varda has now signed a new deal that will allow it to land up to 20 more capsules at the commercial spaceport/range Southern Launch in Australia through 2028.

It has already landed capsules there twice. This new contract suggests that Varda has enough expected customers and products to place in its capsules to pay for about six or seven capsules launched per year. If so, this manufacturing model in space is going to bloom very quickly, and will likely become a major profit center for the commercial space stations now under development.

The deal also illustrates the utter failure of the U.S. government’s red tape, especially during the Biden administration.

The company landed its first mission, W-1, at the Utah Test and Training Range in February 2024. But difficulties securing licenses and other approvals for that mission prompted Varda to look elsewhere. “Through that experience, it became pretty clear that the U.S. was not going to be the location for high-cadence reentry operations in the near term,” Eric Lasker, Varda’s chief revenue officer, said at an IAC event announcing the new agreement.

Hopefully the anti-regulatory policies of Trump will change this, but for the moment our government has driven this American company away from the U.S.

The Starlab consortium, proposing to build its single-module large Starlab space station that will be launched on Starship, has now added the Belgium company Space Applications Services (SpaceApps) as both a partner and investor.

SpaceApps contributes deep experience in space systems, mission operations and payload integration with capabilities that include avionics, payload development, the end-to-end International Commercial Experiment Cubes (ICECubes) service, as well as mission integration and operations control software. The company also works closely with the European Space Agency and international partners, broadening Starlab’s access to global markets and research communities.

The Starlab consortium already includes the American companies Voyager Space and Northrop Grumman and the European company Airbus. It also has a partnership agreement with the European Space Agency. This new Belgium partnership further cements its place as Europe’s potential future space station after ISS is retired.

This deal is only one of several news stories in the past week signaling progress by this consortium. It has signed the American company Vivace to build the station’s main structure and its partner Northrop Grumman has successfully tested the rendezvous and docking technology its Cygnus cargo capsule will use to dock with Starlab. All in all this station appears to be assembling the pieces its needs.

Below is my updated rankings of the four commercial stations under development:

Axiom successfully tests two of its lunar spacesuits underwater

8:01 am

Axiom's two spacesuits being tested underwater

Click for original.

The space station startup Axiom this week successfully completed underwater testing of two of its lunar spacesuits, making them ready for astronaut training.

Axiom won the contract to build these suits for NASA in 2022. It speaks well of the company that only three years later the suits are now ready for use. It also shows NASA’s own incompetence, because before it awarded this contract to Axiom the agency tried to build its own suits, spending more than a billion dollars and fourteen years to produce nothing.

Furthermore, this success underlines yesterday’s NASA inspector general report that lambasted Collins Aerospace’s incompetence in maintaining the spacesuits on ISS. Collins in 2022 had won a similar spacesuit contract to build new space station suits, but two years later backed out of the deal, unable to get the job done.

For Axiom, this spacesuit success adds an essential component to its own space station plans. Though these suits are intended for the Moon, the company now has the basics down for its own space station suit. It owns this suit design, and will not only sell suits to NASA, it can market the suits to any one else.

Inspector General: The state of NASA’s spacesuits on ISS is becoming critical

1:28 pm

NASA's failed spacesuit
NASA’s failed Moon spacesuits

A new NASA inspector report issued today [pdf] has found that the single contractor NASA uses to maintain the spacesuits on ISS, Collins Aerospace, has increasingly been unable to do the job, and NASA has no alternative contractor to turn to. From the report’s executive summary:

We previously reported on NASA’s spacesuit management in 2017 and 2021, finding that the Agency faced a wide array of risks to sustaining the EMUs [the spacesuits], including design inadequacies, health risks, and low inventories of spacesuit life support systems, ultimately leading to NASA’s efforts to design and develop next-generation suits to replace the existing EMUs. Specifically, the EMU design flaws have increased the chance of and led to unexpected water in helmets, thermal regulation malfunctions, and astronaut injuries. Given that spacesuits are necessary to meet future ISS maintenance needs until its planned decommissioning in 2030, it is critical that NASA effectively manages the contract performance and subsequent safety risks associated with ESOC [the contract with Collins].

…Until the ISS’s planned decommission at the end of the decade, NASA will continue to require spacewalking capabilities to perform upgrades and corrective and preventative maintenance to the Station. However, Collins’ performance on ESOC increases programmatic risks to NASA as it attempts to conduct safe spacewalks outside the ISS and maintain critical EMU life support component inventories. The contractor is experiencing considerable schedule delays, cost overruns, and quality issues that significantly increase the risk to maintaining NASA’s spacewalking capability.

Collins was awarded this five-year cost-plus maintenance contract in 2010 for $324 million. Since then NASA has been repeatedly extending it, so that it now runs through 2027 and has funneled $1.4 billion into Collins’ bank account. Yet Collins has repeatedly failed to deliver necessary repair parts, even as there have been more frequent problems on ISS, including several cases where spacewalks had to be aborted because an astronaut’s life was in danger. Here are just a few examples cited in the report:

Firefly loses first stage for next launch when it explodes during static fire test

8:40 am

During a static fire engine test yesterday in preparation for launch, the rocket startup Firefly lost the first stage when an explosion occurred at what appeared to be the base of the rocket. From the company’s update:

During testing at Firefly’s facility in Briggs, Texas, the first stage of Firefly’s Alpha Flight 7 rocket experienced an event that resulted in a loss of the stage. Proper safety protocols were followed, and all personnel are safe. The company is assessing the impact to its stage test stand, and no other facilities were impacted.

Video of the explosion can be seen here.

This incident will obviously delay the next launch, which had only just been scheduled following the completion of the company’s investigation into its launch failure in April. This explosion also suggests there remain serious issues with the Alpha rocket, which has only had two full successes in six launch attempts.

At the same time, with the successful soft landing of its Blue Ghost lander on the Moon earlier this year, Firefly has demonstrated its engineering can be sound and robust. It just appears that a lot more work needs to be done to get Alpha into shape.

China launches two “test satellites”

7:46 pm

China earlier today successfully launched two test satellites for “experimental verification of Earth observation technologies, its Long March 2D rocket lifting off from its Xichang space port in southwest China.

No word on where the rocket’s lower stages, using very toxic hypergolic fuels, crashed inside China. The two satellites are part of the Shiyan family of satellites that have done rendezvous and proximity operations as well as surveillance of other satellites in orbit.

The leaders in the 2025 launch race:

126 SpaceX
58 China
13 Russia
12 Rocket Lab

SpaceX still leads the rest of the world in successful launches, 126 to 98.

Modeling suggests Uranus’s moon Ariel needed underground oceans to shape its known surface

The uncertainty of science: Using computer modeling based on our scant data of the surface features of the Uranus moon Ariel, scientists now posit that underground oceans, some of gigantic depth as much as 100 miles deep, were required to shape those features.

“First, we mapped out the larger structures that we see on the surface, then we used a computer program to model the tidal stresses on the surface, which result from distortion of Ariel from soccer ball-shaped to slight football-shaped and back as it moves closer and farther from Uranus during its orbit,” Patthoff said. “By combining the model with what we see on the surface, we can make inferences about Ariel’s past eccentricity and how thick the ocean might have been.”

The team found that, in the past, Ariel needed to have an eccentricity of about 0.04 [to create those surface structures]. This is about 40 times larger than its current value. While 0.04 may not sound dramatic, eccentricity can strengthen the effects of tidal stresses, and Ariel’s orbit would have been four times more eccentric than that of Jupiter’s moon Europa, which is wracked by the tidal forces that push and pull it to create its cracked and broken surface. Yet, to the eye, the orbit will still resemble a circle.

“In order to create those fractures, you have to have either a really thin ice on a really big ocean, or a higher eccentricity and a smaller ocean,” Patthoff said. “But either way, we need an ocean to be able to create the fractures that we are seeing on Ariel’s surface.”

This result does not prove an underground ocean now exists, or even if one existed in the past. The data is based on the few fly-by images taken by Voyager-2 when it passed close to Uranus in 1986. Coverage of the entire surface of Ariel was not complete, nor did the images have much resolution. The data is suggestive of this conclusion, but not conclusive by any means.

Webb: Accretion disk surrounding exoplanet rich in carbon molecules

10:14 am

Using the Webb Space Telescope, scientists have detected a host of carbon molecules inside an accretion disk that surrounds an exoplanet circling a baby star 625 light years away.

Infrared observations of CT Cha b were made with Webb’s MIRI (Mid-Infrared Instrument) using its medium resolution spectrograph. An initial look into Webb’s archival data revealed signs of molecules within the circumplanetary disk, which motivated a deeper dive into the data.

…Ultimately, the team discovered seven carbon-bearing molecules within the planet’s disk, including acetylene (C2H2) and benzene (C6H6). This carbon-rich chemistry is in stark contrast to the chemistry seen in the disk around the host star, where the researchers found water but no carbon. The difference between the two disks offers evidence for their rapid chemical evolution over only than 2 million years.

You can read the original paper here [pdf]. The exoplanet itself is thought to have a mass 14 to 24 times that of Jupiter, making it almost a brown dwarf star. The NASA makes a big deal claiming this disk is forming a moon around the exoplanet, but that is not what the paper finds. This research did not find any evidence of a new moon exoplanet.

Instead, the paper found an accretion disk rich in carbon molecules, a finding that is significant on its own. It also found that that the accretion disk around the central star, while lacking carbon molecules, appears rich in water.

In other words, this baby solar system is packed with the right material for eventually producing life. Moreover, in this system’s relatively short life, two million years, these materials were able to sort themselves out so that the star has one concentration of material while the exoplanet has another. Both facts suggest that organic chemistry is common in the universe, and can evolve fast.

That is the important discovery here.

Two Japanese startups partner to fly the first private lunar sample return mission

9:53 am

Two Japanese startups, the lunar landing company Ispace and the orbital capsule startup ElevationSpace, have signed an agreement to develop the first private mission to bring samples back to Earth from the Moon.

Based on the agreement, Ispace and ElevationSpace will jointly pursue development to undertake a lunar return mission. Ispace has already demonstrated the technology to deploy a lander into lunar orbit through its two lunar missions operated in 2023 and 2025. The company is currently considering the development of an Orbital Transfer Vehicle (OTV), derived from its existing lunar lander development technology.

The collaboration aims to conduct a technology demonstration to verify the feasibility of missions utilizing an and the sample return re-entry capsule being developed by ElevationSpace, as well as to evaluate the overall system characteristics.

At the moment this project is only a PowerPoint proposal. Though Ispace has made two attempts to soft land an unmanned spacecraft on the Moon, neither was a success. It has three further contracts with NASA, ESA, and Japan’s space agency JAXA, but none has flown yet, and its orbital vehicle is only under development.

As for ElevationSpace, it has flown nothing yet as well. Its first demo satellite, designed to test re-entry and recovery, won’t fly until late next year, assuming its launch rocket, Isar’s new Spectrum, gets to orbit.

Nonetheless, this project illustrates the continuing shift to the private sector in space. The companies are doing this to demonstrate their capabilities in order to win contracts from both commercial and government customers.

New study finds ice is better at dissolving iron than liquid water

9:34 am

In a result that could have a direct bearing on trying to understand the inexplicable geology of Mars, a new study has found that ice actually does a better job at releasing iron from mineral deposits than liquid water.

It was once believed that when iron-rich mineral deposits were locked in ice, the iron would stay put, but a new study from Sweden’s Umeå University shows that the ice itself is actually working better than permafrost melt to release the iron. The study showed that ice at -10 °C (14 °F) releases more iron from mineral deposits than liquid water at 4 °C (39.2 °F). “It may sound counterintuitive, but ice is not a passive frozen block,” says study co-author Jean-François Boily. “Freezing creates microscopic pockets of liquid water between ice crystals. These act like chemical reactors, where compounds become concentrated and extremely acidic. This means they can react with iron minerals even at temperatures as low as minus 30 degrees Celsius.”

The researchers also found that the seasonal freeze/thaw cycle helped this process, and that brackish fresh water did better in dissolving the iron than seawater.

The significance for Mars geology is that this suggests glacial ice in the alien Mars climate might be the catalyst for creating its meandering canyons that so much resemble features on Earth produced by liquid water. On Mars however no model yet has been convincingly successful in creating past conditions where liquid water could flow on the surface. Mars has either been is too cold or its atmosphere too thin to allow it.

This study suggests ice however could do the work. It also fits with other Martian data that suggests the same, that at the base of the Martian glaciers pockets of liquid water could exist that act to shape the canyons.

All of this is speculation on my part, but it seems that the planetary scientists who are studying Mars should take a close look at this research.
