China’s Manned Space Agency (CMSA) yesterday unveiled its proposed spacesuit for the planned manned lunar landings it hopes to achieve by 2030.

As shown on the left, the suit draws its design from the Russian Orlan suit. The large backpack-like unit is also a hatch. The astronaut opens it, drops into the suit, and then a partner closes the unit, locking it shut. The rest of the suit is a single piece, with the central body unit rigid and the arms and legs flexible.

The Russian’s Orlan suit has been upgraded a number of times over the years, but the basic design has proved to be practical, efficient, and reliable, generally the oppose of the unwieldy and complex American suits NASA has been using since the start of the shuttle era.

The announcement was made to initiate a contest for the public to pick a name for the suit. Like all such contests, the real goal is to provide bread-and-circuses to the public so that they can think they have some say in what is happening. In the end the government will pick the name, and find someone who made the same suggestion to “award” for the idea.

SpaceX pauses launches after de-orbit of Falcon 9’s second stage misfires

10:37 am

SpaceX today announced that, after its Falcon 9 rocket had successfully placed two astronauts in orbit in its Freedom capsule, the engine burn designed to de-orbit the rocket’s upper stage in a safe zone in the ocean misfired, and for this reason the company was scrubbing a planned launch today until the root cause was found.

After today’s successful launch of Crew-9, Falcon 9’s second stage was disposed in the ocean as planned, but experienced an off-nominal deorbit burn. As a result, the second stage safely landed in the ocean, but outside of the targeted area.

We will resume launching after we better understand root cause

The company provided no further details on exactly what happened. We know the engine fired, and the stage was successfully de-orbited safely over the ocean, but we do not know how far outside its target zone. Nor do we know the extent of the “off-nominal deorbit burn.”

At present today’s scrubbed launch, placing three satellites of Starlink’s competitor OneWeb into orbit, is scheduled for tomorrow, but that is likely a contigency scheduling. SpaceX’s launch teams have gotten very good at rescheduling launches day-to-day, so that as soon as it gets the go-ahead it can go ahead.

SpaceX launches two astronauts to ISS, setting new annual launch record for the U.S.

11:17 am

SpaceX this morning launched two astronauts to ISS in the fourth flight of the Freedom Dragon capsule, the Falcon 9 rocket lifting off from Cape Canaveral.

The first stage completed its second flight, landing back at Cape Canaveral. Freedom will dock with ISS tomorrow.

While most news stories will focus on the rescue aspect of this mission, its crew reduced by two so that the two astronauts launched in June on Boeing’s Starliner capsule can come home on it in February, the real news story is that with this launch the United States set a new record for the number of launches in a single year. With this launch the U.S. has completed 111 successful launches in 2024, exceeding the record set last year’s of 110 launches. And this record was achieved in less than three quarters of the year. At this rate is it very likely the U.S. will double the record of 70 set in 1966 that lasted until 2022.

China meanwhile completed its own launch late yesterday, its Long March 2D rocket placing what China’s state-run press described as “its first reusable and returnable test satellite,” designed to do orbital operations and experiments, return to Earth with those materials, and then later relaunch again. This is very similar to the commercial capsules that the startup Varda is flying and using to produce pharmaceuticals for sale.

The rocket lifted off from China’s Jiquan spaceport in northwest China. No word where its lower stages, using toxic hypergolic fuels, crashed inside China.

The leaders in the 2024 launch race:

95 SpaceX
44 China
11 Russia
11 Rocket Lab

American private enterprise now leads the rest of the world combined in successful launches 111 to 67, while SpaceX by itself now leads the entire world, including American companies, 95 to 83.

Crazy swirling Martian landscape

1:48 pm

Crazy swirling Martian landscape
Click for original image.

Cool image time! The picture to the right, cropped, reduced, sharpened, and annotated to post here, was taken on July 1, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The science team labels this “Contacts between Likely Sulfates and Chaos Blocks.” That contact I have indicated with the dotted line. To the west the lighter terrain is likely the sulfate-bearing unit, similar to the sulfate-bearing unit that Curiosity has been traversing on Mount Sharp for the past year or so.

To the east are the chaos blocks, but I think that description is wholly inadequate. In truth, I haven’t the faintest idea how this terrain got to be the way it is. It is evident that a lot of dust and sand has gotten trapped in the hollows, leaving behind ripple dunes in some places, but why the higher ridges swirl and curve about as they do is utterly baffling.

Scientists locate lunar impact crater produced by LCROSS in 2009

11:07 am

Using orbital radar and opitcal images scientists finally believe they have identified the small crater on the Moon produced when — as part of the 2009 LCROSS mission — an abandoned rocket stage crashed in a permanently shadowed section of Cabeus crater near the lunar south pole.

LCROSS was designed to study the ejecta thrown up by that impact, and found “a significant amount of water, estimated at 5.6 ± 2.9% by mass, as well as minor amounts of other volatile species.” Because the impact was in that permanently shadowed region, however, locating the new crater required new instrumentation.

Using a radar instrument on Lunar Reconnaissance Orbiter (LRO) as well as the Shadowcam instrument on South Korea’s Danuri orbiter — designed to take optical images in very low light — the scientists pinpointed that impact crater, as shown in the image to the right, overlaying both the radar and optical images. The crater is estimated to be about 22 meters across, about 25% smaller than predicted. From this the scientists conclude that the water in the ejecta plume came from close to the surface, and thus could only have been placed there in the past billion years. Before that, the location was not in shadow, and volatiles like water could not have survived if they were near the surface.

From this data the scientists believe the water was likely placed there by the “recent delivery by comets or the solar wind, rather than as a paleo-reservoir from an early volcanic atmosphere.” If so, the amount of material can be reasonably predicted, and is likely less than hoped for because it only exists in the top two meters.

Rocket Lab completes new capsule for Varda

9:10 am

Varda's space capsule, on the ground in Utah
Varda’s first capsule on the ground in Utah.

Rocket Lab today announced it has completed testing and intergration of a new recoverable capsule for the in-space manufacturing company Varda, to be used in orbit to produce pharmaceuticals that can only be created in weightlessness.

No launch date was announced. This was the second of four capsules Rocket Lab is building for Varda, with the first having already completed its flight, where it returned to Earth after successfully crystallizng the HIV drug Ritonavir.

The most important tidbit in the press release however was this:

Varda received permission from the FAA under a Part 450 license earlier this month, making them the only company to ever secure a second reentry license.

With the first capsule, the capsule’s return was delayed almost six months because the FAA and the military couldn’t get their paperwork together to approve the return license. Varda now has that return license in hand before launch, meaning it will get the capsule back when it wants.

Starlink now has four million subscribers

9:00 am

According to SpaceX’s CEO, Gwynne Shotwell, during testimony in a hearing before the Texas state legislative committee and confirmed by a SpaceX tweet on X, Starlink now has a total of four million subscribers.

The milestone would mean that SpaceX has gained a million new customers since the end of May alone. This outpaces the company’s already impressive rate of growth: Starlink started providing beta service of its product in October 2020; it hit 1 million subscribers in December 2022, 2 million subscribers in September 2023, and 3 million in May. The constellation now comprises nearly 6,000 satellites, with service available in nearly 100 countries to individual users as well as large enterprise customers like major airlines and cruise lines.

The service is on track to generate $6.6 billion in revenue this year — an increase from roughly $1.4 billion just two years prior, according to industry research and consulting firm Quilty Space. [emphasis mine]

With $6.6 billion in yearly revenue, in two years SpaceX will get as much from its customers as it has raised in investment capital. It essentially does not need to look for more funding, as it is now earning enough to pay for both Starlink as well as the development of Starship/Superheavy. Furthermore, at this point the company no longer needs NASA’s government funds to do anything it wants to do.

Nor are these numbers the end. Yesterday it was also reported that Air France had signed up Starlink for its airplane fleet, coming after both United and Hawaiian airlines announced they were switching to Starlink as well.

No wonder the left as well as the federal bureaucracy — dominated by top-down authoritarians who love governemnt rule — are hostile to SpaceX. It no longer needs them, and that independence threatens their power.

Orbital tug startup D-Orbit raises another 150 million euros

8:44 am

The orbital tug company D-Orbit announced today that it was able to extend its more recent round of fund-raising by 50 million euros, and raise a total of 150 million in private investment capital instead.

Japan’s Marubeni Corp. led the Series C round. Marubeni has exclusive rights to distribute D-Orbit’s services in Japan in Southeast Asia, according to the news release.

New and existing investors participating in the round include: Avantgarde, CDP Venture Capital, Iberis Capital, Indaco Venture Partners, the European Innovation Council, Neva, Phaistos Investment Fund, Primo Ventures and Seraphim Space Investment Trust. Also joining the round was a consortium led by United Ventures that included the European Investment Bank and the European Investment Fund.

I call the company a “startup” in the headline, but that probably is now incorrect. It already has flown fourteen orbital tug missions, with seven more scheduled in 2025. At this point it is well established, and could extend this most recent funding round.

Musk and Shotwell once again blast red tape against the company

12:54 pm

The EPA to SpaceX
The EPA to SpaceX “Nice company you got here.
Sure would be a shame if something happened to it.”

In a follow-up to SpaceX’s blunt critical response to the attacks against it by the head of the FAA, Mike Whitaker during House testimony on September 24, 2024, Elon Musk in a tweet yesterday called for Whitaker to resign.

That blast however was only the start. During a different hearing on September 24th before the Texas state house appropriations committee, Gywnne Shotwell, the CEO of SpaceX, called the actions of the EPA to regulate the launch deluge system for Starship/Superheavy “nonsense.”

“We work very closely with organizations such as the (Texas Commission on Environmental Quality),” she said. “You may have read a little bit of nonsense in the papers recently about that, but we’re working quite well with them.”

…On Tuesday, Shotwell maintained that the the system — which she said resembles “an upside down shower head” — was “licensed and permitted by TCEQ [Texas Commission on Environmental Quality] … EPA came in afterwards and didn’t like the license or the permit that we had for that and wanted to turn it into a federal permit, which we are working on right now.”

…The state agency has said the company received a stormwater permit — a type that’s usually quickly approved — but did not have the permit required for discharge of industrial wastewater produced by launches. That type of permit requires significant technical review and usually takes almost a year to approve. [emphasis mine]

The problem with this demand by both EPA and TCEQ is that SpaceX is not dumping “industrial wastewater produced by launches.” The deluge system uses potable water, essentially equivalent to rain water, and thus does zero harm to the environment. In fact, a single rainstorm would dump far more water on the tidal islands of Boca Chica that any of SpaceX’s Starship/Superheavy launches.

Thus, this demand by the EPA clearly proves the political nature of this regulatory harassment. The unelected apparatchiks in the federal bureaucracy are hunting for ways to stymie and shut down SpaceX, and they will use any regulation they can find to do so — even if that use makes no sense. And they are doing this because they support the Democratic Party wholesale, and thus are abusing their power to hurt someone (Elon Musk) who now opposes that party.
