Chinese pseudo-commercial rocket industry gearing up to launch numerous times from interior spaceport

12:07 pm

China's spaceports

Even as China is presently building a commercial launch facility at its Wenchang spaceport on the coast, at least four of China’s pseudo-commercial rocket companies are gearing up to launch numerous times from the Jiuquan Satellite Launch Center in the interior of China.

The link above shows the launch sites being built at Jiuquan by pseudo-companies Landspace, Expace, CAS Space, and Space Pioneer. The map to the right illustrates what these interior launches will mean. Since none of these pseudo-companies will be vertically landing their first stages — at least not for several years — it means that numerous first stages will be coming down in many areas in China and Mongolia, most of which will be uncontrolled descents.

Eventually the Wenchang launch facility on the coast will become available, but based on past Chinese actions, do not expect these pseudo-companies to end their operations at Jiuquan at that time. All are controlled by the Chinese government, which has made it very clear it really doesn’t care if first stages crash near habitable areas.

Hubble looks at a nearby dwarf galaxy

9:38 am

A nearby dwarf galaxy
Click for original image.

Cool image time! The photo to the right, cropped, reduced, and sharpened to post here, was taken by the Hubble Space Telescope as part of a continuing project to capture high resolution images of every nearby galaxy, which in this particular case the caption describes as follows:

UGCA 307 hangs against an irregular backdrop of distant galaxies in this image from the NASA/ESA Hubble Space Telescope. The small galaxy consists of a diffuse band of stars containing red bubbles of gas that mark regions of recent star formation, and lies roughly 26 million light-years from Earth in the constellation Corvus. Appearing as just a small patch of stars, UGCA 307 is a diminutive dwarf galaxy without a defined structure — resembling nothing more than a hazy patch of passing cloud.

The red regions of star formation are significant, as they indicate that even in a tiny galaxy like this it is possible for there to be enough gas and dust to coalesce into new stars.

Astronomers living on a world inside this galaxy have an advantage over astronomers on Earth. There is no large galaxy like the Milky Way blocking their view of the cosmos in one direction. They can see it all, even in directions looking through UGCA 307.

Russia and China launch satellites

9:20 am

Two launches today in Russia and China.

First China used its Long March 2C rocket to launch a “remote sensing satellite” into orbit. No other information about the satellite was released. Nor was any information about whether the rocket’s first stage landed near habitable areas.

Next Russia used its Proton rocket to launch a classified satellite, likely a military surveillance satellite, into orbit. Like China Russia launches from an interior spaceport, with its first stage falling “in Karaganda Region of Kazakhstan,” with the second stage landing in drop zones in Russia. Russia, which has been doing this regularly for more than a half century, has always done a good job either avoiding habitable areas with the first stage crash, or keeping such stories out of the international press.

The 2023 launch race:

16 SpaceX
9 China
4 Russia
1 Rocket Lab
1 Japan
1 India

American private enterprise still leads China 17 to 9 in the national rankings, and the entire world combined 17 to 15. SpaceX alone is now tied with the entire world, including all other American companies, 16 all.

Curiosity looks ahead: Which way to go?

10:23 pm

Curiosity's view on March 11, 2023
Click for high resolution version. For original images, go here and here.

Overview map

How about a bonus weekend cool image! The panorama above, created from two pictures taken on March 11, 2023 by the right navigation camera on the Mars rover Curiosity, gives us a wonderful view of the alien Martian terrain that the rover is presently within. It also shows us the dilemma mission planners have in planning the rover’s future travels.

The red dotted line on both the panorama and the overview map to the right indicates the planned route. The yellow lines on the map indicates the approximate area viewed by the panorama. The blue dot marks Curiosity’s present position, where it is presently in the middle of a drilling campaign in the marker layer where it sits.

The plan had been to travel to the east of what I like to call the the hill of pillows (in the middle of the panorama). Yet, it appears from this navigation image that the terrain might be less difficult to the west. Both routes will get the rover to its goal in Gediz Vallis.

I have no idea what the mission planners will decide to do. I am just a tourist going along for the ride, and sharing the journey with my readers. This is the first time any human spacecraft has ever traveled through such mountainous terrain on any planet.

Relativity scrubs launch today again

2:06 pm

Relativity today was once again unable to complete the first launch of its Terran-1 prototype rocket.

The failure to launch was not for want of trying. The first countdown was first put on hold at T-1:10 when a boat entered the range. Once removed, the launch team picked up the count from that point without any recycle, but at T-0 the rocket’s internal computer sensed an issue and aborted the launch.

The launch team then reassessed, adjusted that issue, and tried again for a launch at the last second of the launch window, essentially duplicating the circumstances of an instantaneous launch window. The count this time got down to T-45 seconds when once again the rocket’s internal computer sensed an issue and aborted the launch.

No word yet on when the company will try again. If anything, Relativity’s launch team is getting a lot of practice and training with each launch attempt, critical knowledge needed for future launches.

Some space startups threatened by Silicon Valley Bank failure

9:41 am

Link here. The companies mentioned in the article are Astra, BlackSky, Planet, Redwire, Rocket Lab, and Space Perspective.

Rocket Lab has about 8% of its cash assets now trapped by the closure. All the companies had loans from Silicon Valley Bank, some of which were paid off prior to the crash. This quote suggests the situation is critical for some space startups:

“It’s a very serious situation,” said a space sector entrepreneur who asked not to be identified. “Our balance is suddenly only $450. There has been no communication from SVB even after the event became known. Our primary SVB liaison, who has been very attentive in the past, is unreachable by any means. It’s appalling.”

Live stream of the first launch attempt of Relativity’s Terran-1 rocket

9:15 am

I have embedded below the live stream of the first launch attempt of Relativity’s Terran-1 rocket, presently scheduled with a three hour launch window that opens at 1:00 pm (Eastern). The live stream will go live at noon.

The first launch of a new rocket is exceedingly challenging, and almost never succeeds. The key however is the data obtained that can be used to make the next launch attempt a success.

A lot rides on this launch. Relativity already has obtained $1.2 billion in launch contracts plus more than $1 billion in private investment capital, despite having never launched anything. Moreover, the Terran-1 rocket is really a prototype for its larger Terran-R rocket, which is intended to compete directly for the larger payloads that companies like SpaceX and ULA launch.

Ingenuity completes 47th flight, scouting ahead of Perseverance

Though the science team has not, as of this posting, added the flight to Ingenuity’s flight log, according to the interactive map showing the positions of both Ingenuity and Perseverance on Mars, the helicopter completed its 47th flight yesterday as planned.

An annotated version of that map is to the right. The larger green dot marks Ingenuity’s new position. The smaller green dot marks its position when the panorama above was taken on February 27, 2023, capturing the helicopter in the distance (as indicated by the arrow). The yellow lines indicate the approximate area covered by that panorama. The blue dot marks Perseverance’s present position.

The flight’s planned distance was to go 1,410 feet to the southwest and “image science targets along the way.” As the helicopter also flew above Perseverance’s planned route, as indicated by the red dotted line, it also provided the rover team information about the ground Perseverance will travel along the way. Since the terrain here is generally not very rough, the information is not critical for route-picking. It might however spot some geological feature that bears a closer look that would not have been noticed by the rover alone.

Biden administration proposes more budget increases for NASA

10:25 am

In releasing its proposed federal budget for 2024 with many major spending increases, the Biden administration has also proposed a significant increase in NASA’s budget. the third year in a row it has done so.

The shortened summary version of the Biden budget proposal [pdf] covers its proposals for NASA in two pages, with the most important proposals as follows:

  • A half billion dollar increase in the budget for the Artemis program for a total of $8.1 billion.
  • A commitment to partner on Europe’s ExoMars Franklin rover mission, replacing Russia.
  • $949 million to develop the Mars sample return mission to bring back Perseverance’s core samples.
  • $180 million to begin development of “a space tug” that can de-orbit ISS as well as “be useful for other space transportation missions.”
  • $1.39 billion for developing new space technologies, an increase of $190 million.

The last two items will likely be money offered to many new commercial startups.

Though we can expect some resistance by the Republican House to most of the budget increases in the overall Biden budget proposal, expect Congress to rubber stamp the NASA increases, as it has done routinely in recent years. Congress might shift or reject some of these ideas, but generally, when all is said and done, it will only make superficial changes. NASA will likely more money.

House subcommittee proposes five bills that would change FCC operations

10:06 am

The House Energy and Commerce subcommittee on March 8, 2023 approved five bills affecting the FCC and how it operates.

The first bill [pdf], Satellite and Telecommunications Streamlining Act, is the most significant, as it appears to try to establish legal limitations and rules specifically designed to address the FCC’s recent effort to expand its power and regulatory authority beyond what its legal authority allows. While most of the bill’s language appears to allow the FCC to do what it wants (including limiting or regulating future space stations and setting lifetime limits on all orbiting spacecraft), it also insists that licenses be approved quickly and adds this caveat:

[T]he Commission may not establish performance objectives that conflict with any standard practice adopted by the Secretary of Commerce.

In other words, the FCC cannot grab the regulatory responsibilities of other agencies, especially the Commerce Department, where Congress in recent years has been trying to shift most commercial regulatory authority.

Nonetheless, this bill appears to mostly endorse the FCC ‘s power grab.

The bills still have to be approved by the full committee, then approved by the full House, then approved by the Senate, and then signed by the president.

Russia considering bringing Soyuz launched on February 23rd home earlier

9:35 am

According to unnamed sources in the Russian press, Roscosmos officials are considering bringing the Soyuz capsule launched on February 23rd to ISS back to Earth in June rather than September, while moving up the launch of the next Soyuz manned mission.

As noted by space journalist Anatoly Zak:

The existence of such plans indicated that specialists had still been concerned about the possibility of a critical leak in the thermal control system of the fresh crew vehicle similar to those that hit two previous transport ships. Such change in schedule would also debunk the official explanation of previous two accidents by Roskosmos and NASA as caused by meteors rather than production defects.

The two previous coolant leaks occurred about three months after launch. Bringing the Soyuz home in June would get it home in about three and a half months, suggesting the Russians are no longer confident their Soyuz and Progress spacecraft can withstand six months in space.

If this plan is adopted it will also put less strain on the crew slated to come home on that Soyuz. Their mission has been planned for six months. Extending it to a full year without any prior preparation risks serious health issues.
