China launches solar science telescope

China today used its Long March 2D rocket to launch its first solar science telescope, Advanced Space-borne Solar Observatory (ASO-S), also known as Kuafu-1.

The probe, which was first proposed in 1976 (!), has a four year nominal mission and is designed to monitor the Sun as goes through its next sunspot maximum. More information can be found here.

China’s Long March 11 launches from floating sea platform

China today successfully launched two “navigation satellites” from a floating sea platform in the Yellow Sea, using its Long March 11 rocket.

The platform was only about two miles off shore at launch, so the view from the beach drew a large crowd. Video at the first link.

Is China-Russia partnership to build lunar base dead?

China/Russian Lunar base roadmap
The so-called Chinese-Russian partnership to explore
the Moon.

In 2021 China and Russia announced a long term plan to jointly explore the Moon, with the project eventually leading to the construction of a joint lunar base.

The graphic to the right comes from that announcement. It lists all lunar missions being built by both Russia and China, and outlined the step-by-step process in which both will work together to build that base.

At the time I noted the likelihood of serious Russian delays, since confirmed. I then noted this:

This decision [by Russia to delay] also demonstrates that Russia’s so-called partnership with China to explore the Moon …is pure hogwash.

Russia’s track record in space since the fall of the Soviet Union has been poor. It hasn’t been able to complete almost any project on time, with many dying stillborn. Most of the time Russian authorities make big announcements of big plans, but nothing ever gets built.

It appears now that China has recognized this reality. In presentations at the International Astronautical Congress (IAC) in Paris last week, China repeatedly offered payload space on its many planetary missions — as listed to the right — to outside nations and even private concerns.

Based on China’s recent track record, those missions will fly, and will likely fly close to their predicted launch dates. Since its space program is designed by China to promote itself, it hopes to get others to participate for propaganda reasons. It also hopes it can then steal some technology from that partnership, as also shown by its long term track record.

What China’s presentations at IAC did not do, however, was mention Russia.

The only visible representation of potential Russian [participation] came in a slide listing future Chinese Chang’e and Russia Luna missions, alongside graphics of the Chinese Long March 9 super heavy-lift rocket and a large Russian launch vehicle. The slide was taken straight from ILRS handbook released to coincide with the St. Petersburg event in 2021, and Russia nor its missions were not explicitly named.

It is hard to say if the lack of representation of Russian involvement reflects a change in Beijing’s thinking or a sensitivity to the current geopolitical context. But China appears to face a dilemma for its grandest space ambitions so far.

It appears China has recognized the paper tiger nature of its partnership with Russia. It hasn’t precluded the partnership, but it realizes that its program to explore the Moon and the solar system must move forward independent of Russia, or else Russia will act like a lead weight to slow it down.

Radar data from Zhurong finds no ice to a depth of 260 feet

Zhurong's ground-penetrating radar data

Overview map

Chinese scientists today finally published their results from the ground-penetrating radar instrument on their Mars rover Zhurong, revealing that to a depth of 260 feet (80 meters), it detected no clear signal of water ice.

Figure 2 of their paper, posted above, summarizes their results. It shows the radar profile to 328 feet (100 meters) depth along Zhurong’s route, as shown in the map to the right, with the last bit of its recent travels ending somewhere in the blue circle. From the paper:

Our low-frequency radar imaging profile shows radar signals within the depth range of 0–80 m (Fig. 2a), precluding the existence of a water-rich layer within this depth range as the existence of water would strongly attenuate the radar signals and diminish the visibility of deeper reflections. The estimated low (less than 9) dielectric permittivity (Fig. 2c) further supports the absence of a water-rich layer as water-bearing materials typically have high (greater than 15) dielectric permittivity.

We further tested this assessment with thermal considerations by conducting a heat conduction simulation based on available thermal parameters estimated from previous studies (Methods). Our thermal simulation results … show that the Zhurong landing area has an annual average temperature of around 220K in the RoPeR detection depth range, which is much lower than the freezing point of pure water (273K), and also lower than the eutectic temperatures of typical sulfate and carbonate brines, but slightly above those of perchlorate brine systems. This observation suggests that the shallow subsurface of the Zhurong landing area could not stably contain liquid water nor sulfate or carbonate brines, consistent with the radar imaging result.

The data suggests that below the surface topsoil layer, the regolith, there are two distinct layers of material that the scientists interpret as possible evidence of past catastrophic floods. That conclusion however is very very uncertain. The main take-away is that in the northern lowland plains of Utopia Planitia at 25 degrees north latitude, where Zhurong landed, Mars is definitely a dry desert, with no water close to the surface.

This data also suggests that if you establish a colony anywhere in Mars’ dry equatorial regions within 30 degrees latitude of the equator, you will likely have to travel north or south a considerable distance to get to easily accessible ice. The global map of Mars below shows the regions where ice is most evident, north and south of 30 degrees latitude.

Two Chinese launches: Long March 2D and Long March 6 put satellites into orbit

China successfully completed two launches in the past twelve hours, placing four satellites into orbit in total.

First, in the evening of September 26th, a Long March 2D rocket launched a “remote sensing” satellite into orbit. This was then followed in the morning of September 27th with the launch of a Long March 6 rocket, putting three “experimental” Earth observation satellites into orbit. We know nothing more about any of these satellites.

The article at the link lists a third launch, of a Kuaizhou-1A rocket, but I have already reported that.

The leaders in the 2022 launch race:

43 SpaceX
41 China
12 Russia
7 Rocket Lab
6 ULA

American private enterprise still leads China 60 to 41 in the national rankings. Against the entire world combined, the U.S. now trails 60 to 61.

Mostly shows views of the Earth.

At the link the reason given is the “problems with the delivery of foreign-made parts.” Or to put it more bluntly, the sanctions against Russia due to its unprovoked invasion of the Ukraine has blocked many sophisticated computer parts that Russia cannot make itself.

All fantasy at this point. Russia’s been promising a next generation capsule replacing Soyuz for more than a decade.

Video at the link. The test occurred on September 23, 2022. No word yet on when they plan to launch.

China’s Kuaizhou-1A rocket launches two satellites

Early today China’s smallsat Kuaizhou-1A rocket successfully launched two “experimental” satellites into orbit from an interior spaceport.

The satellites are part of a classified program, so little is known about them.

Tomorrow ABL Space will attempt to launch from Alaska its RS1 smallsat rocket for the first time. Later in the week Firefly will make its second attempt to launch its Alpha rocket successfully. I will embed the live streams, if available.

Russia launches three astronauts to ISS; China launches Earth observation satellite

Russia today successfully used its Soyuz-2 rocket to launch three astronauts to ISS, two Russians and an American flying as part of the NASA-Roscosmos barter deal whereby each agency flies an astronaut from the other in order to make sure everyone knows how to use each other’s equipment.

China in turn today used its Long March 2D rocket to launch an Earth observations satellite into orbit.

China’s Long March 7A launches communications satellite; dumps debris on Philippines

China today launched its Long March 7A rocket from its coastal Wenchang spaceport, successfully placing a communications satellite into orbit.

The coastal launch site meant that the rocket’s lower stages would not fall on China’s interior. Instead, it appears the drop zones were located in the Philippines.

The [Philippines Space] agency said it was able to verify the estimated drop zones of the rocket debris from a notice by the Civil Aviation Administration of China. “Two drop zones within the Philippine territory have been identified based on the NOTAM: Drop zone 1 is approximately 71 kilometers from Burgos, Ilocos Norte, while drop zone 2 is approximately 52 kilometers away from Sta. Ana, Cagayan,” PhilSA said in an advisory.

No word on whether this debris caused any damage. Regardless, China is continuing its policy, in violation of the Outer Space Treaty, of recklessly dumping rocket stages on others.

The leaders in the 2022 launch race:

41 SpaceX
37 China
11 Russia
6 Rocket Lab
5 ULA

American private enterprise still leads China 56 to 37 in the national rankings, but is now tied with the entire world combined 56 to 56. This tie will likely not be long-lived. Though Firefly’s launch has been delayed until next week, SpaceX and Rocket Lab have launches scheduled for today and tomorrow, respectively.

Chinese astronauts complete first spacewalk using new Wentian module

The new colonial movement: Chinese astronauts yesterday completed their first spacewalk using the airlock on the new Wentian module that was recently launched to that nation’s Tiangong-3 space station.

The spacewalk lasted six hours, and was mostly designed to test the airlock itself as well as do the first tests of Wentian’s own robot arm. It appears they also installed an “extended pump set”, whatever that is, and did other work near the hatch. More here.

That’s nice, but years have passed and the first Dream Chaser cargo spacecraft, Tenacity, has still not flown. It is well past time for this company to finally get off the ground.

This also be the first spacewalk using the airlock on the space station’s new Wentian module.

It appears to be built by the pseudo-company Orienspace.

Indian research project for China’s space station threatened by Chinese-India military conflict

A science instrument from India, slated to fly on a Chinese rocket to China’s Tiangong-3 space station, is now threatened by the military tensions between the two nations.

The project, called Spectrographic Investigation of Nebular Gas (SING), also involves collaboration with the [India] Institute of Astronomy [IIA], Russian Academy of Sciences, and has been designed and developed by research students at the IIA. The plan is to have it ready by the year end so that it can be launched in the summer of 2023. Though the plan is on schedule, scientists at the IIA are now consulting with the Indian Space Research Organisation (ISRO) as well as the Ministry of External Affairs (MEA) on whether they are in the clear to go ahead with the project.

Chinese and Indian troops have been engaged in a prolonged stand-off in eastern Ladakh. The two sides have so far held 16 rounds of Corps Commander-level talks to resolve the stand-off, which erupted on May 5, 2020, following a violent clash in the Pangong lake area.

It appears the Indian government is having second thoughts about this cooperative project. After decades of naive trust in the communists from both Russia and China, it seems India has finally realized the communists really have little interest in helping India, being more focused on using it for good PR while it steals Indian technology. Moreover, India now realizes that China has become a dangerous neighbor, willing to use its newfound power violently at the border between the two countries.

Two Chinese pseudo-companies pursuing suborbital tourist market

Link here. One company is apparently copying Blue Origin’s New Shepard, though its capsule’s exterior looks more like a copy of SpaceX Dragon capsule.

The other company however is doing something very unusual for a Chinese space operation. It appears to be designing something original, not a copy of some American achievement.

Space Transportation’s goal is to develop a suborbital spaceplane capable of carrying tourists on suborbital flights. The winged system is very different from Virgin Galactic’s SpaceShipTwo suborbital vehicle, which is currently in flight test.

A larger Space Transportation vehicle would be a high-speed transport that would fly between distant locations on Earth in less than two hours.

…The company released very little information about the six launches it conducted this year. It’s not even clear where the flights took place, although Wikipedia indicates they might have been conducted from the Jiuquan Satellite Launch Center.

If successful, Space Transportation will have have done something almost unprecedented for China, building something from an entirely original design.

China launches hi-res Earth observation satellite

China today used its Long March 2D rocket to place a new version of a smallsat Earth observation satellite into orbit. Dubbed the Beijing-3B, it appears to be an upgrade of a design first launched last year.
