One of NASA’s two Tracers satellites just launched has an issue

10:17 am

During the commissioning phase shortly after their launch earlier this week, one of NASA’s two Tracers satellites designed to study the solar wind and its interaction with the Earth’s magnetic field has had an as yet unnamed issue.

During the commissioning process, the team made routine adjustments to the power subsystem on both vehicles. While the adjustments achieved the desired results on one satellite, the other satellite requires further investigation by the team. Commissioning operations are temporarily paused while the team analyzes the situation and determines the appropriate response.

Though the press release provides no other information, it appears the satellite is having a problem producing the power expected.

NASA’s work force is shrinking by about 4,000

10:11 am

The number of NASA employees that have accepted the Trump offer to leave has now grown to more than 4,000 people, reducing the entire workforce from 18,000 to 14,000.

Nearly 4,000 employees, or more than 20% of NASA’s workforce, have applied to leave the agency, NASA confirmed to CBS News Friday. About 3,870 employees have applied to depart NASA over two rounds through the Trump administration’s deferred resignation program, NASA disclosed. The deadline for applications to the program is midnight Friday.

With those deferred resignations, NASA’s civil servant workforce would shrink from about 18,000 to 14,000 personnel. This figure also includes about 500 employees who were lost through normal attrition, the agency said.

It is certain that while Trump is office these workers will not be replaced. While most of the press and pro-government activists will claim this is terrible news, it is actually the best thing that can happen. Since NASA is now trying to use the capitalism model across the board, it doesn’t need that many employees. It is hiring the private sector to do most of its work. It doesn’t take that many people to review and issue a contract.

So, even if Congress rejects Trump’s proposed 24% cut to NASA’s 2026 budget and funds it entirely at the same levels as in 2025, the money will be more effectively used.

Europe and SpaceX complete two launches late yesterday

10:01 am

Both Europe and SpaceX successfully completed launches in the early morning hours today.

First Arianespace, the European Space Agency’s (ESA) commercial arm, used Avio’s Vega-C rocket lifting off from French Guiana to put five satellites into orbit, including four high resolution Earth observation satellites and one climate satellite. This was only the third launch for Arianespace in 2025, two of which were of the Vega-C.

Next, SpaceX placed 28 Starlink satellites into orbit, its Falcon 9 rocket lifting off from Cape Canaveral. The first stage completed its 22nd flight, landing on a drone ship in the Atlantic.

The leaders in the 2025 launch race:

92 SpaceX
37 China
10 Rocket Lab
9 Russia

SpaceX now leads the rest of the world in successful launches, 92 to 66, with another Starlink launch scheduled for tonight.

Mars and its two moons seen in the infrared by Europa Clipper

10:37 am

Mars and its two moons
Click for original.

Cool image time! The infrared image to the right, cropped, reduced, and enhanced to post here, was taken by Europa Clipper on February 28, 2025 just before it flew past Mars on its way to Jupiter.

Deimos is in the upper left corner, while Phobos is close to Mars.

When the image was taken by the mission’s Europa Thermal Emission Imaging System (E-THEMIS), the spacecraft was about 560,000 miles (900,000 kilometers) from the Red Planet. The image is composed of 200 individual frames, part of a continuous scan of 1,100 frames taken roughly a second apart over a period of 20 minutes. Scientists are using the tiny, point-like images of the moons to check the camera’s focus.

As this is an infrared image (measuring heat), it shows Mars’ northern polar cap as the dark oval at the top of the planet. The bright (and thus warmer) oval to the lower left is the shield volcano Elysium Mons.

This data suggests Europa Clipper’s thermal instrument is working as intended, which is essential for observing the ice content (if any) on Europa once it enters Jupiter orbit in 2030.

Dassault lobbies ESA to fund its Vortex reusable mini-shuttle

9:51 am

The French aerospace company Dassault is now lobbying the European Space Agency to help finance its proposed Vortex reusable mini-shuttle, comparable in concept to Sierra Space’s Dream Chaser spacecraft.

The company had first announced this project in June.

While the June announcement included few details, a 25 June hearing of the French National Assembly’s Committee on National Defence and the Armed Forces revealed that the mission is expected to be launched in 2027 aboard a Rocket Lab Electron rocket. The hearing also disclosed that the demonstration mission has a total budget of €70 million, with Dassault providing more than half of the funding and the remainder coming from the French government.

Dassault is now attempting to get more funding from ESA. In June it had signed an agreement with ESA to partner on building a demonstrator, but it was not clear that agreement included funding. It certainly did not include funding for the full scale operational mini-shuttle.

Overall, the structure of funding and the design of the project is good, and demonstrates again Europe’s sharp shift to the capitalism model in the past two years. Dassault will design, build, and (most importantly) own the shuttle, allowing it to market it to many customers. It is also committing a significant amount of its own funds to the project. The funding from France and possibly ESA appears mostly that of a customer buying the services of this product from the company.

Starlink went down for almost 3 hours yesterday

9:31 am

In what is a rare event, SpaceX’s Starlink satellite constellation was out of service yesterday for about 2.5 hours “due to failure of key internal software services that operate the core network.”

Starlink experienced an outage Thursday afternoon that went on for 2.5 hours and took down at least tens of thousands of people’s satellite internet service. “Starlink is currently in a network outage and we are actively implementing a solution. We appreciate your patience, we’ll share an update once this issue is resolved,” Starlink posted on X at 1:05 p.m. PT/4:05 p.m. ET.

Though Starlink has yet to confirm that services are fully up and running again, Downdetector showed reports of issues had dropped to just 1,600 as of 4:30 p.m PT after they’d spiked to around 60,000 at about 1 p.m. PT

CNBC incorrectly tried to pin this internet outage to the start yesterday of T-Mobile’s new cellphone-to-Starlink text and emergency subscription, but that makes no sense, since the two use different Starlink satellites.

Since the constellation began offering customers its service several years ago the number of such global outages has been very rare. If anything, Starlink has been far more reliable than almost all comparable land line internet services.

Like the Senate the House appropriation committee rejects Trump’s NASA cuts, but differently

9:20 am

The NASA 2026 budget approved this week by the House appropriation committee has rejected the 24% cut proposed by the Trump administration, in a similar manner as the parallel Senate committee.

However, the two congressional committees are not in agreement on any of their spending proposals.

The totals recommended by the two committees are similar — $24.8 billion in the House, $24.9 billion in the Senate — but the specifics are different in many cases.

For example, the House wants to spend $300 million for NASA’s very messed-up Mars Sample Return project, while the Senate eliminated it entirely. The House also increases NASA’s manned exploration budget over Trump’s proposal, while the Senate cuts it. In science spending the House is less generous than the Senate, though both houses reject Trump’s cuts. In education the House agrees with Trump, zeroing out that funding, while the Senate wants to increase the ’25 budget slightly.

Before the 2026 budget is approved the two houses will have to negotiate an agreement to make their numbers match. What has usually happened in past negotiations is that the houses agree to approve the highest spending numbers in any budget item so that nothing gets cut and the budget continues to go up uncontrollably. We should not be surprised if our corrupt Congress does exactly that.

Even so, we should expect Trump to force significant changes at NASA, including budget reductions. Recent Supreme Court rulings have confirmed the president’s right to reorganize and even eliminate bureaucracies, as long as Congress doesn’t specify a particular spending item.

Russia launches two weather satellites

8:36 am

Russia today successfully placed two weather satellites into orbit, its Soyuz-2 rocket lifting off from its Vostochny spaceport in eastern Russia.

Video of the launch here. This was the second launch for this new constellation of satellites. The rocket flew north from Vostochny, crossing Russia with its lower stages and four strap-on boosters falling in designated drop zones inside Russia. No word if anything landed near habitable areas.

The leaders in the 2025 launch race:

91 SpaceX
37 China
10 Rocket Lab
9 Russia

SpaceX still leads the rest of the world in successful launches, 91 to 65.

The glaciers on Mars are almost pure ice with only a thin cover of dust and debris

9:55 am

According to new research, scientists now think that the glaciers on Mars are almost pure ice, protected from sublimation by a thin cover of dust and debris.

Work over the last 20 years has demonstrated that at least some of these glaciers are mostly pure ice with only a thin cover of rock and dust, but according to a new paper published in Icarus, glaciers all over the planet actually contain more than 80% water ice, a significant finding. Ultimately, this means that Mars’s glacial ice deposits are nearly pure across the globe, providing a clearer understanding of Mars’ climate history and a possible resource for future utilization.

The researchers analyzed mid-latitude glaciers at five different locations in both the north and south hemispheres, and found that at every location the data suggested almost pure ice.

The map to the right, from earlier research, shows the prevalence of near-surface ice once you get above 30 degrees latitude. From the poles to the mid-latitudes it appears there is an ice sheet or “ice table” just below the surface. In the mid-latitudes glaciers dominate, as this appears to be the region where that ice is beginning to dissipate. In the equatorial regions little or no near-surface ice has been detected, though there has been some evidence in some places of ice at deeper depths.

This data once again demonstrates that Mars is not a desert like the Sahara, as we once believed. Instead, it more resembles Antarctica, where there is ice everywhere that simply needs to be processed for use.

T-Mobile makes its Starlink capability available to everyone

9:34 am

T-Mobile officials yesterday announced that it is now offering its Starlink text and location cellphone capabilities available by subscription to all users, whether or not they are a T-Mobile customer.

On Wednesday, T-Mobile CEO Mike Sievert announced that the Starlink-powered service is officially out of beta, though it only supports text messaging and location-sharing for now. The new satellite coverage option is called “T-Satellite,” and it’s currently available as a standalone subscription. It’s being offered at $10 per month for a “limited time,” before increasing to $15 per month. It also comes included for customers on the carrier’s $100 per month Experience Beyond or older Go5G plans.

Your device will automatically connect to T-Satellite if you’re in an area with no cellular coverage. As long as there isn’t a heavy amount of cloud coverage or trees blocking your view of the sky, you should be able to send and receive text messages, including to 911, as well as share a link that temporarily tracks your location.

At present, the service is only available in the United States, though it will expand as SpaceX launches more cellphone-to-satellite Starlink satellites. T-Mobile also expects to add voice capability as well.

Nor is this the only option. AT&T is partnering with the satellite company AST SpaceMobile to offer similar services.

Mexico’s president says it will investigate SpaceX for doing salvage operations off its coast

9:26 am

Mexico to SpaceX:
Mexico to SpaceX: “Nice business you got here. Shame
if something happened to it.”

You can’t win with these people: First Mexico’s president Claudia Sheinbaum complained loudly about the debris that landed or washed up on its beaches after several of SpaceX’s Starship/Superheavy test launches, demanding an investigation followed by sanctions against the company.

Now Sheinbaum is complaining and demanding a new investigation about SpaceX’s effort the last two weeks to salvage and remove that debris from the ocean off its coast.

During a passage of her daily press conference, Sheinbaum said the agencies are analyzing whether the company has to be sanctioned after its unit tasked with clearing debris from the Starship launch, located in the Gulf of Mexico, worked without proper authorization. “We are investigating but the Environment, Navy, Digital Transformation, Government and Foreign Relations secretariats are conducting their research. The study is practically done,” Sheinbaum said.

Navy Secretary Raymundo Pedro Morales Angeles said the company hired by SpaceX to retrieve debris from its Starship rocket was allowed to enter the country but didn’t fulfill the requirements to work and ended up leaving the country.

If this behavior doesn’t prove Sheinbaum’s lust for power and control, nothing will. She doesn’t really care about Mexico’s beaches or environment. If she did, she would celebrate SpaceX’s salvage operations. What she really doesn’t like is that someone is doing something without her permission. She is the boss, and SpaceX better remember that!

Rocket startup IRocket mergers with investment company

9:10 am

The rocket startup IRocket has now gone public by merging with the special purpose acquisition company (SPAC) BPGC, with the latter committing $400 million in investment capital in the merged company.

Innovative Rocket Technologies Inc. (iRocket), a next-generation reusable space rocket developer, and BPGC Acquisition Corp. (BPGC), a special purpose acquisition company sponsored by The Hon. Wilbur Ross, the 39th U.S. Secretary of Commerce with more than 55 years of private equity and investment banking experience, and BPGC Management LP, an independent private equity firm dedicated to opportunistic buyouts and special situations transactions in the global industrials, materials and chemicals sectors, jointly announced today that they have entered into a definitive Merger Agreement and Plan of Merger dated July 22, 2025, in connection with the previously-announced letter of intent.

Upon closing, the combined company will operate under the name iRocket Technologies Inc. and the parties will plan to list the combined company on Nasdaq.

The press release at the link makes a lot of very ambitious claims about the company’s proposed rocket, claims that so far appear to be nothing more than nice PowerPoint graphics.

iRocket’s Shockwave launch vehicle is uniquely designed for recovery and reuse of all of its stages. Just as airplanes fly multiple flights, iRocket will Recondition, Reload, and Relaunch™ its rockets in under 24 hours. iRocket’s patented liquid rocket engines will maintain high efficiency through descent as well as ascent. iRocket’s engines will be fueled with sustainable liquid oxygen and methane, which burns cooler, imparts less stress on components, and further supports iRocket’s unique 24-hour turn-around time. Being on a leading edge with its rocket engine expertise, iRocket is also developing solid rocket motors that will transform boosters, missiles, and interceptors.

The company has been around since 2018, yet as far as I can determine has never launched anything. One would hope that something real will begin to finally happen with this infusion of significant new capital.
