China successfully launches new large module to its Tiangong space station

Tiangong-3, completed
Tiangong-3 station, when completed

The new colonial movement: China on July 24, 2022 (China time) has successfully used its Long March 5B rocket to put into orbit its Wentian module, the next large section that will dock with the Tiangong station in the next day or so.

According to one announcer, the core stage will not crash to Earth in an uncontrolled manner, as in previous Long March 5B launches. However, this is China, and his statement cannot be taken at face value. We shall find out in the coming days if this is so, or whether the core stage will be a threat to habitable areas as its orbit decays.

The leaders in the 2022 launch race:

32 SpaceX
24 China
9 Russia
5 Rocket Lab
4 ULA

The U.S. still leads China 45 to 24 in the national rankings, as well as the entire globe combined 45 to 40.

Watch China’s launch of next big module to its Tiangong space station

The launch of the next big module to China’s Tiangong space station, dubbed Wentian, is scheduled for 2:15 am (eastern) tonight, using its Long March 5B rocket.

The live stream is embedded below if you want to watch. It begins at about an hour before launch.

I have added a live stream in English, below the first. One detail of importance that this broadcast has already revealed: According to one technical expert being interviewed, the core stage will not crash to Earth uncontrolled. They will be able to bring it down where and when they want.

China releases one photo of Phobos taken by its Tianwen-1 Mars orbiter

Phobos as seen by Tianwen-1
Click to see original photo.

China today released a single photo of the Martian moon Phobos, taken by its Tianwen-1 Mars orbiter, to mark the second anniversary of the orbiter’s launch.

The English press release at the link conveniently did not provide the image to the non=Chinese world, but the Chinese language release did. That picture is to the right, reduced slightly to post here. Considering its disinterest in making it easy to find this photo for English speakers, it is intriguing that China included the English language name Opik for one crater.

Moreover, this single picture release illustrates the paucity of Tianwen-1 photos made available to the public by China. Very few have been released, and though eventually China has been making its raw data available, it has not been doing so in a manner that makes it easy for outsiders to access it.

Nonetheless, this is one of the best pictures of Phobos I have yet seen.

NASA’s safety panel questions NASA commitment to commercial space stations

We’re here to help you! Not surprisingly, members of NASA’s safety panel have once again expressed doubts about NASA’s ongoing effort to encourage a thriving private, competitive, and efficient commercial space industry, this time questioning the transition from NASA’s government-built space station, ISS, to privately-built and owned space stations, four of which are presently under development.

At a July 21 meeting of the Aerospace Safety Advisory Panel, members said they were concerned that commercial stations whose development is being supported by NASA were unlikely to be ready in time before the ISS is retired at the end of the decade, and that those efforts suffered from insufficient budgets.

Those plans, called Commercial Leo Earth Orbit (LEO) Destinations by NASA, β€œare on a precarious trajectory to realization on a schedule and within the projected resources needed to maintain a NASA LEO presence,” said Patricia Sanders, chair of the panel. β€œThis is an area of concern for us.”

The panelists also questioned how quickly the stations would be man-rated (claiming NASA was not allocating enough time to do so) as well as whether NASA had enough work for four stations.

For the past decade this safety panel has consistently shown itself to be hostile to the new commercial space companies. It has never seen any safety issues or scheduling problems with NASA’s big SLS rocket. Nor did it notice Boeing’s significant software and valve problems on Starliner. Yet somehow, the work of SpaceX was dangerous (when it was not), and now these new stations, most of which are being built by new space companies, are equally unfit for use.

It is time to shut down this panel. Or at a minimum fire its present members and bring in new blood more willing to look at the entire space industry with a more objective eye.

SpaceX successfully launches another 46 Starlink satellites

Capitalism in space: SpaceX today successfully used its Falcon 9 rocket to place another 46 Starlink satellites into orbit.

The first stage, completing its fourth flight, landed successfully on a drone ship in the Pacific.

This was SpaceX’s 32nd launch in 2022, exceeding the record of 31 launches it set last year, and doing so only a little more than halfway through the year.

The leaders in the 2022 launch race:

32 SpaceX
23 China
9 Russia
5 Rocket Lab
4 ULA

American private enterprise now leads China 45 to 23 in the national rankings, and the entire globe combined 45 to 39.

Collapsed dunes in Jezero Crater

Collapsed dune on Mars
Click for full image.

Cool image time! The photo above, cropped and reduced to post here, was taken on July 20, 2022 by one of high resolution cameras on the rover Perseverance. It shows what appears to be a collapsed dune on the floor of Jezero Crater.

The arrows mark the highest dune ridge line that suddenly ends at a cliff, with the sand that is piled up at its base appearing almost like it flowed like thick mud outward away from that cliff. Apparently, that material broke off in one single event sometime in the past.

Note the many parallel lines pointing outward from the base of the cliff. These lines appear to reflect the internal structure visible in the cliff itself. Somehow, when that sand collapsed, it flowed away while retaining some of that structure.

When this collapse happened is unclear. I don’t think it has happened recently, since Perseverance’s arrival, but I could be wrong.

China rethinking its proposed heavy lift rocket to make it a Starship clone

Long March 9, now a Starship clone

Chinese rocket designers appear to be rethinking the proposed design of the Long March 9 heavy lift rocket that China is building, switching from an expendable clone of NASA’s SLS to a reusable clone of SpaceX’s Starship/Superheavy.

The original design had called for three expendable stages and four strap-on expendable boosters using kerosene fuel, and was targeting a 2030 launch. The new design is two reusable stages, with the first having 26 engines fueled by methane, and would launch by 2035.

The image to the right is a screen capture from a presentation given by a long time rocket designer in China, viewable here cued to this point. Note the two large rockets on the right. The smaller is a two stage version, while the larger is a three stage version. Both look remarkably like Starship/Superheavy.

Isar Aerospace signs deal to launch from French Guiana

Capitalism in space: The German smallsat rocket startup Isar Aerospace has now signed a deal with the French space agency CNES to use one of its launchpads in French Guiana for launches of its new Spectrum rocket.

The Diamant pad was built more than a half-century ago for the French rocket of the same name, but has been dormant for decades. CNES is now working to convert the facility into a multi-user site for small launch vehicles, and Isar is the first company the agency selected in an open competition to use the site.

Isar also has a deal to launch from Norway. As recently as seven months ago the company was claiming its first test launch would occur there before the end of ’22. All told, Isar has three different launch contracts and has raised almost $200 million in investment capital.

Draper wins NASA contract to put a lander on the Moon’s far side

Capitalism in space: NASA yesterday awarded a $73 million contract to the space company Draper to place a lander on the Moon’s far side by 2025.

The lander, called SERIES-2 by Draper, will deliver to SchrΓΆdinger Basin three experiments to collect seismic data, measure the heat flow and electrical conductivity of the lunar subsurface and measure electromagnetic phenomena created by the interaction of the solar wind and plasma with the lunar surface.

The mission is the eighth NASA has awarded to date as part of CLPS, but the first to go to the lunar farside. The only mission by any country to land on the far side of the moon is China’s Chang’e-4 mission, which successfully landed in Von KΓ‘rmΓ‘n Crater in January 2019 and deployed the Yutu 2 rover that remains operational today.

With this award, there are presently five American companies with contracts to put landers on the Moon, Intuitive Machines, Astrobotic, Firefly, and Masten. Masten however shut down operations recently. This new contract to Draper for almost the exact same amount that had been awarded to Masten appears to replace Masten in the program.

SpaceX launch aborted 46 seconds before launch

Capitalism in space: In what has become a rare event for SpaceX, the company was forced to abort a launch of a Falcon 9 rocket today carrying 46 Starlink satellites only 46 seconds before launch.

The company has scrubbed a few launches in the past three years due to weather, but I think this is the first launch abort apparently due to a technical issue in several years.

No details were given for the abort, but whatever the issue was, it was apparently not serious, as the launch team immediately announced that they have recycled the launch to its back-up date tomorrow.
