Did China test a hypersonic weapon in August?

10:14 am

Long March 2C rocket
China’s Long March 2C rocket

On October 17th The Financial Times published a story claiming, based on anonymous sources, that one of China’s five launches in August tested a hypersonic weapon, which supposedly circled the globe to impact the Earth only 24 miles from its target.

The Financial Times story is behind a paywall, but not surprisingly it was picked up by much of the mainstream press, with the conservative press — as illustrated by this Daily Wire story — accepting the weapon as fact, while the leftist press — as illustrated by this CNN story — giving China the opportunity to deny the claim.

Did it actually happen? I have no idea. I would add however that I would not trust any story dependent wholly on anonymous sources, considering the unreliability of today’s press and the repeated evidence that numerous federal agencies in the military and intelligence communities routinely feed it disinformation for their own political purposes. These agencies, including the Space Force, want to encourage Congress to fund them, and creating a bogey man threat that the press can tout has for decades been the standard way to do it.

To get a better idea whether this hypersonic flight happened, let’s review the actual Chinese launches in August to see if any might be a likely candidate. For a launch to fit the description, there would have to be almost no information about its payload, and that payload would have to have not reached orbit, since the hypersonic test circled the globe once and then impacted the Earth.

China gets failed satellite to proper orbit

9:19 am

A Chinese satellite launched in late September that failed to reach its designated orbit after deployment has now reached that correct orbit.

During the launch of the Chinasat 9A mission in June 2017, the Reaction Control System (RCS) of the rocket stopped working during the coast phase, which resulted in a sub-planned payload release. The satellite, however, used its onboard propulsion to reach the desired orbit even with the rocket underperforming.

In September the limited information released by China suggested the launch had been a success but the satellite failed after deployment. Based on this new information, the launch in September only became a success now, as the failure was in the rocket’s upper stage.

China has not revealed the purpose of this satellite, though it is part of a program known to launch satellites for testing cutting edge technology.

China successfully launches three astronauts to its space station

9:36 am

Launch of Shenzhou

The new colonial movement: China today successfully used its Long March 2F rocket to place three astronauts into orbit to begin a six month mission to that country’s new space station.

The image to the right is a screen capture from the live stream, mere seconds after launch.

It appeared to me that the rocket’s first stage might have had grid fins to control its reentry, but I am not certain. Either way both it and the four strap-on boosters will crash in China.

The Shenzhou capsule will dock with the station in a few hours.

The leaders in the 2021 launch race:

36 China
23 SpaceX
17 Russia
4 Northrop Grumman

China has now moved ahead of the U.S. in the national rankings, 36 to 35.

Watch launch of next crew to Chinese space station

9:00 am

I have embedded the live stream of today’s launch of three astronauts to China’s space station, presently being assembled in orbit. This crew’s mission is planned for six months. More details here. From China’s state-run press is this description of the planned tasks during the mission, including two or three spacewalks as well as the addition of two more large modules to the station.

Liftoff is set for 12:23:44 p.m. (Eastern).

China launches eleven satellites on Long March 2D rocket

12:08 am

China today launched eleven satellites using its Long March 2D rocket, with the primary payload a solar observation telescope, designed to observe the Sun in the hydrogen-alpha wavebands.

The hydrogen-alpha wavelength is deep red and is centered at 656.28 nanometers – for comparison, visible light runs from 400 to 700 nanometers. Observing the Sun at the hydrogen-alpha wavelength can reveal structures, evolution, and dynamic processes associated with solar flares and filaments. Hydrogen-alpha observations can also reveal solar wave phenomena, which are precursors to coronal mass ejections, and the dynamics of activity in the Sun’s lower atmosphere.

The rocket’s first stage was also equipped with grid fins similar to those used on SpaceX’s Falcon 9. Their goal at this time is simply to more precisely guide that expendable first stage back to its drop zone in the interior of China, thereby preventing it from crashing into habitable areas.

The leaders in the 2021 launch race:

35 China
23 SpaceX
17 Russia
4 Northrop Grumman

The U.S. and China are now tied at 35 successful launches in the national rankings. With three more launches expected in the next three days, one by China and two by the U.S., expect these numbers to rise quickly.

Chang’e-5 lunar samples youngest ever found

6:28 am

The uncertainty of science: The lunar samples returned to Earth by China’s Chang’e-5 lander have been found to be the youngest ever found, about two billion years old and a billion years younger than any other previous sample, with a composition that confirms the material in this area was also the youngest volcanism so far found on the Moon.

Collecting young lunar rocks was one of the main objectives for the Chang’e-5 mission, which sent a lander to the Moon in December 2020. The craft grabbed 1.7 kilogram (4 pounds) of lunar regolith from the vast volcanic plain of Oceanus Procellarum and flew back to Earth within the month. Observations from lunar orbit had identified this mare to be younger than other areas by its paucity of craters, which suggested that the lava there had flowed more recently. By dating the samples returned to Earth, the scientists confirm that volcanism occurred later in Oceanus Procellarum than other areas of the Moon.

Many news stories are claiming that the young age of these samples is a surprise, but this isn’t true. It was expected, as the quote above indicates.

However, the composition of the rocks did not match what was expected. Though created by volcanism, it appears the material did not have kind of composition seen in other lunar volcanic rocks. This is now a new puzzle for scientists.

Yutu-2 and Chang’e-4 successfully complete another lunar day on the Moon

10:52 am

According to China’s state-run press, its lunar rover Yutu-2 and the lander Chang’e-4 have now successfully completed another lunar day on the far side of the Moon, with both still functioning well.

Yutu-2 has traveled a total of 839.37 meters, or about 2,753 feet. They are aiming for a location that is still about 3,400 feet away. Based on the rover’s travel pace, about 100 feet per lunar day, it will take them about another two or four years to get there.

China’s Long March 3B successfully launches satellite, which then fails

9:58 am

China’s Long March 3B rocket successfully launched a military satellite yesterday, though the satellite then had an undisclosed issue which caused it to fail.

Though the satellite failed to function immediately after launch, it appears the launch itself was successful, which based on my criteria means this launch is counted in China’s 2021 launch totals. The leaders in the 2021 launch race are thus:

34 China
23 SpaceX
15 Russia
4 Northrop Grumman

The U.S. still leads China 35 to 34 in the national rankings.

China launches unmanned Tianzhou freighter to its space station

9:05 am

The new colonial movement: In preparation for the arrival of its next three-person crew, China yesterday successfully used its Long March 7 rocket to launch an unmanned Tianzhou freighter to its new space station, docking there seven hours later.

The Long March 7 is a new rocket that launches from China’s Wenchang spaceport on the country’s southern coast. Thus, its expendable stages fall into the ocean, not within China. The rocket also does not use toxic hypergolic fuels, but kerosene and oxygen, so it is less environmental harmful.

The crew will launch to the station on October 13th and will likely spend six months at the station.

The leaders in the 2021 launch race:

32 China
23 SpaceX
15 Russia
4 Northrop Grumman

The U.S. still leads China 34 to 32 in the national rankings.

China’s three astronauts land safely

9:33 am

The new colonial movement: China’s three astronauts safely returned to Earth today after spending 91 days in space and 90 days on China’s new space station.

During their stay they did two spacewalks preparing the station for additional modules and later missions.

China is expected to send the robotic Tianzhou 3 cargo spacecraft toward Tianhe around Sept. 20. And the next crewed mission to the module, the six-month-long Shenzhou 13, is apparently scheduled to launch in mid-October. (Exact target dates are hard to come by with Chinese missions, because the nation tends not to announce many details of its spaceflight plans in advance.)

China will also in the next year launch two more large modules to attach to the station, using its Long March 5B rocket. Assuming they have not redesigned that rocket, expect the very large upper stage on both launches to once again crash out-of-control somewhere on the Earth, possibly in habitable areas.

Chinese astronauts undock from space station in return to Earth

10:07 am

The new colonial movement: Three Chinese astronauts, having completed their 90 day mission on China’s new space station, early today boarded their Shenzhou capsule and undocked from the station, with the expectation that they will return to Earth sometime tomorrow.

The astronauts have already set China’s record for the most time spent in space. After launching on June 17, mission commander Nie and astronauts Liu and Tang went on two spacewalks, deployed a 10-meter (33-foot) mechanical arm, and had a video call with Communist Party leader Xi Jinping.

Following their safe return, China will launch another unmanned cargo freighter to the station, followed by the launch of three more astronauts for another 90 day mission, continuing the station’s assembly construction. In addition to several more manned flights, in the next two years two more large modules will added.

NOTE: The New York Times actually did some good [and increasingly rare] journalism today to point out that the number of people presently in space, 14, is a record, beating the 13 that were on ISS in 2009. The difference now is that those spacefarers are on three different and very independent projects, ISS, the Chinese space program, and the first entirely private space mission launched by SpaceX.

China’s Chang’e-5 orbiter returning to lunar space

9:25 am

The new colonial movement: In a somewhat bold move, Chinese engineers appear to now be shifting the Chang’e-5 orbiter so that it will be able to return to lunar space to fly past the Moon.

The orbiter, one of four distinct Chang’e-5 mission spacecraft, delivered a return module containing 1.731 kilograms of lunar samples to Earth Dec. 16 before firing its engines to deep space for an extended mission.

The Chang’e-5 orbiter later successfully entered an intended orbit around Sun-Earth Lagrange point 1, roughly 1.5 million kilometers, in March. There it carried out tests related to orbit control and observations of the Earth and Sun.

New data from satellite trackers now suggests Chang’e-5 has left its orbit around Sun-Earth L1 and is destined for a lunar flyby early September 9 Eastern time.

This data comes not from China but from amateur astronomers who specialize in tracking satellites.

The fly-by could provide the spacecraft the velocity it needs to reach near Earth asteroid Kamo’oalewa, which China has said it is targeting for a 2024 sample return mission. Such a reconnaissance will help them design the sample return mission.

China Long March 4C rocket launches satellite

8:33 am

According to China’s state-run press, the country launched an “earth observation” satellite today using its Long March 4C rocket.

The satellite is part of a series of similar satellites launched by civilian agencies ostensibly for civilian use. The rocket was launched from an interior spaceport. No word on whether its first stage carried grid fins or parachutes to control its landing in the interior of China, or whether it crashed near habitable areas.

The leaders in the 2021 launch race:

China building Ingenuity copycat

9:36 am

Ingenuity vs China

China’s space program revealed yesterday that it is designing its own Mars helicopter for future missions to the Red Planet.

The picture to the right shows this Chinese helicopter prototype on the bottom, with Ingenuity on Mars on top.

Notice the similarity? In fact, one could almost say that the Chinese helicopter is an outright steal of the JPL design.

But then, why not? According to an 2019 inspector general report [pdf], China hacked into JPL’s computers twice from 2009 to 2017 and stole 500MB of data. That data almost certainly included the design plans for Ingenuity, under development at the time.

Copying the work of others is expected, especially when that design is found to work. In this case however it almost certainly isn’t copying, but outright theft.

Of course, that has been par for the course for China’s space program. They don’t appear to be capable of innovating on their own. They first must steal someone else’s design, and then revise and upgrade from that. Their final products might be of high quality, but in the end their long term ability to build something new is going to be severely limited, if they cannot start inventing things on their own.

Zhurong completes 100 days on Mars

9:39 am

Zhurong's loaction, August 31, 2021

The new colonial movement: In announcing today that its Mars rover Zhurong has completed 100 days on the Martian surface, the state-run Chinese press released one very low-resolution panorama taken at the rover’s new position, and a map showing its full route since landing.

The map to the right, created by placing that route on a high resolution Mars Reconnaissance Orbiter image, shows us where Zhurong presently sits as well as where it might travel next. It still appears that they are attempting to reach the heat shield used during landing, which also suggests that they are giving high priority to the engineering aspects of this mission, possibly ranking that component higher than any science they get.

If high resolution versions of that panorama are available, they are probably only available on the Chinese language sites, which makes it very difficult for a non-Chinese-speaker to find.

According to the release, the rover has now traveled just under 3,500 feet, which means it is maintaining a pace greater than 1,000 feet per month. The release also noted this fact about the rover’s upcoming travels, as well as the Tianwen-1 orbiter being used as a communications relay satellite:

The probes will experience a sun outage in mid-to-late September when the Sun is aligned with Earth and Mars, with the solar radiation interfering with the communication between the probes and ground stations. The orbiter and rover will stop working until the sun outage comes to an end.

This conjunction occurs every two years. It means there will also be a pause in data from the American rovers and orbiters. When the last conjunction occurred in September 2019, the communications shutdown lasted about two weeks.

China studying the construction of large-scale structures in space

9:57 am

The new colonial movement: China has now indicated that it has established a project to study methods for building very large structures in orbit, with uses ranging from generating beamed solar power to providing mega-sized manned spaceships and space stations.

Though vague, the project would have practical applications for potential megaprojects including colossal space-based solar power stations. Such facilities would be based in geostationary orbit and span kilometers. These stations would collect solar energy and transmitting power to Earth through microwaves.

Kilometer-scale, ultra-large spacecraft are described as “major strategic aerospace equipment for the future use of space resources, exploration of the mysteries of the universe, and long-term habitation in orbit,” according to the project outline within the mathematical and physical sciences attachment to the released document.

The project would focus on minimizing the weight of the spacecraft to reduce the number of launches and construction, according to an initial report by the South China Morning Post.

It appears that this project is only in its preliminary design phase, with a budget of $3.2 million. Its existence however reinforces the overall rational and long term approach China’s government is taking to space exploration. At this moment they mean business, and are focused on getting the cutting edge technology designed and built rather then maintaining a bureaucratic infrastructure and the jobs that go with it — as NASA and Russia have been doing for the past forty-plus years.

China completes two launches

2:23 pm

China today successfully completed two launches, using from different spaceports its Long March 2C and Long March 3B rockets.

The 2C launched a two demo internet communications satellites designed to eventually be used in a large constellation similar to the constellations of SpaceX and OneWeb. The launch also included a third unidentified communications satellite.

The 3B placed in orbit what is believed to be a military reconnaissance satellite.

Both rockets dumped their first stages somewhere in the interior of China. No word on whether those stages carried parachutes or grid fins to better control their landing, or crashed near habitable regions.

The leaders in the 2021 launch race:

29 China

China’s astronauts complete 2nd spacewalk at Tianhe space station

9:50 am

The new colonial movement: Two Chinese astronauts yesterday successfully completed a six hour spacewalk, installing components on the outside of the Tianhe space station module necessary for future construction work.

The pair, wearing second generation Feitian (“flying to space”) extravehicular mobility suits, completed installing foot restraints and an extravehicular working platform to the large robotic arm. Chinese media outlets streamed footage of the EVA. … The EVA also included work on a panoramic camera, installing a toolkit, adding a pump set for the Tianhe thermal control system and other apparatus in preparation for the arrival of two further modules in 2022. The EVA was completed at 2:33 a.m. Friday, around an hour ahead of schedule.

The first spacewalk occurred in the first week in July.

These astronauts have been working at the station since mid-June, and are expected to return to Earth in mid-September, completing a three month mission. Shortly thereafter a new cargo freighter will launch to the station to provide supplies for the next crew, due in October.

Zhurong completes its planned 90-day mission on Mars

8:54 am

China’s state-run press announced today that its Mars rover Zhurong has successfully completed its planned 90-day mission, is operating without issues, and will continue its exploration of the Red Planet.

The rover has traveled 889 meters as of Aug. 15, and its scientific payloads have collected about 10 Gb of raw data. Now the rover runs stably and operates in good condition with sufficient energy. The CNSA added that the rover will continue to move to the boundary zone between the ancient sea and the ancient land in the southern part of Utopia Planitia and will carry out additional tasks.

According to the administration, Zhurong operated with a cycle of seven days during its exploration and detection. Its navigation terrain camera obtained topographic data along the way to support the rover’s path planning and detection target selection.

Zhurong’s subsurface detection radar acquired the data of the layered structure below the Martian surface, which analyzes the shallow surface structure and explores the possible underground water and ice. [emphasis mine]

This announcement reveals two tantalizing details. First, they are extending the mission, and plan to continue traveling to the south, with a very long term fantasy goal of reaching the transition zone between the northern lowland plains that Zhurong landed in and the southern cratered highlands. That fantasy goal is about 250 miles away. At the pace Zhurong is traveling, about 1,000 feet per month, it will take about a 100 years to cover that ground. Even so, as they move south they are slowly going up hill, and have the chance of seeing some change in the geology along the way.

The second tantalizing detail is indicated by the highlighted last sentence, and is probably the most important data obtained by Zhurong. It suggests they obtained good data from the rover’s ground penetrating radar, and it indicated the existence of underground layers. Whether those layers contain ice however is not clear. From the story it appears the data has not yet been analyzed enough to say.

China, politics, and space

11:17 am

This interesting essay today describing China’s space policy and its ramifications for the United States found this most significant quote from a Chinese official:

A senior official with the CNSA’s lunar program has been reported by the Daily Beast as saying the moon and Mars (and presumably myriad other rocks out there) are the equivalent of the islands in strategic locations in the Indo-Pacific region that China contests with Japan and other countries:

The universe is an ocean, the moon is the Diaoyu Islands, Mars is Huangyan Island. If we don’t go there now even though we’re capable of doing so, then we will be blamed by our descendants. If others go there, then they will take over, and you won’t be able to go even if you want to. This is reason enough.

The fact the CCP views real estate in the solar system the same way as real estate on Earth is both instructive and amusing.

I don’t find this Chinese attitude amusing in the least. It suggests quite starkly China’s intention to claim all the land it occupies in space, in direct violation of the Outer Space Treaty. Unlike the western nations, it doesn’t care that under that treaty’s restrictions, it can’t provide property rights to its citizens. It will possess everything it gets in space, for itself.

All the more reason for the U.S. to push for the Artemis Accords, which China rejects, as those accords bypass the restrictions of the Outer Space Treaty and make property rights possible in western space settlements. In the end, every nation that establishes a base or colony in space is going to claim it, notwithstanding the Outer Space Treaty, so establishing a framework for U.S. law in those colonies is essential. The accords are a first step in doing so.

China to fly asteroid sample mission in ’24

9:19 am

The new colonial movement: Chinese scientists have revealed that China is now building an asteroid sample mission to launch in ’24 and grab samples in ’25 from the near Earth asteroid dubbed Kamoʻoalewa.

According to a correspondence in Nature Astronomy, there are two typical approaches to sampling asteroids like Kamoʻoalewa, namely anchor-and-attach and touch-and-go.

The former requires delicate and dangerous interactions with the planetary body but allows more controllable sampling and more chances for surface analysis. The latter, used by Hayabusa 2 and OSIRIS-Rex, is a quick interaction facilitated by advanced navigation, guidance and control and fine control of thrusters.

China’s mission will use both architectures in order to “guarantee that at least one works.” The paper states that there is “still no successful precedent for the anchor-and-attach architecture,” meaning a possible deep space first. A 2019 presentation reveals that China’s spacecraft will attempt to land on the asteroid using four robotic arms, with a drill on the end of each for anchoring.

The attempt to do both these approaches is audacious, especially because the evidence from both OSIRIS-REx and Hayabusa-2 is that it will be difficult to safely land and hold onto a rubble pile asteroid. The material is too loosely held together.

China gives vague hints about its manned lunar lander

10:02 am

According to this Space News article today, China has recently allowed some tantalizing hints become public about its plans to build a manned lunar lander.

The brief news report from Xiamen University School of Aeronautics and Astronautics July 1 (Chinese) names individuals leading projects pertinent to China’s human lunar landing plans and notably refers to the landing project as a “national strategy”.

…The report names Yang Lei as “chief commander of the crewed lunar landing vehicle system” at the China Academy of Space Technology (CAST), a subordinate to the state-owned space and defense contractor China Aerospace Science and Technology Corp. (CASC). Yang was accompanied for the visit to Xiamen University by the project’s deputy chief commander and another involved in CAST’s new-generation crew spacecraft developed for deep space journeys. Other CASC subsidiaries are working on a new human-rated launch vehicle.

No details of the lander were provided during the meeting, in which current progress and future plans for human moon landings were presented. A number of slides were published but were intentionally blurred out.

Such secrecy is not unusual for China. It is one of the reasons it opposes the Artemis Accords, which require a transparancy in plans that China does not wish to give.

The secrecy however suggests that while they have now named the individuals in charge of the project, they have not yet settled on their design for that lander, and are exploring options. Based on long term schedule for lunar exploration that China and Russia have jointly announced, the first manned landings are planned sometime after ’26.

To meet that schedule they need to get moving on building that lander, now. This story suggests they are now gearing up to do that.

Zhurong travels another 700 feet on Mars

11:46 am

Zhurong's location

According to a new update from China’s state-run press today, since the last update of its Zhurong Mars rover on July 31st, the rover has traveled just over 700 feet, for a total travel distance of about 2,624 feet, just under a half mile.

As of August 6, 2021, the rover has worked on the surface of Mars for 82 Martian days and the orbiter has been in orbit for 379 days. The two are in good condition and functioning properly.

The report provides no other real information.. I have indicated on the map to the right the range in which this travel distance could have taken Zhurong. Hopefully they will release more information soon.

The nominal mission was originally planned for 90 days. Right now it looks like the rover will easily exceed that.

Chinese pseudo-private rocket fails during launch

2:23 pm

A launch attempt by the pseudo-private Chinese company iSpace failed today, the second failure in a row for this company following a success.

A Hyperbola 1 rocket lifted off from the Jiuquan launch base at 3:39 a.m. EDT (0739 GMT; 3:39 p.m. Beijing time), China’s government-run Xinhua news agency said. Xinhua, which described the launch as a “flight test,” said the rocket exhibited “abnormal performance” after liftoff. Officials did not immediately specify when during the flight the rocket failed.

The news agency said a satellite carried by the rocket “did not enter orbit as scheduled.” Chinese officials did not identify the payload lost on the mission.

This is the second launch failure in a row, following the first successful orbital launch in July 2019.

The rocket is made of four solid-fueled stages, which means it most certainly is using military tecnology and is being closely supervised by the Chinese government. ISpace is one of about four such pseudo-private Chines companies. In each case, China is allowing private Chinese capital to finance the development of these rockets, for use both by the Chinese government as well as sale to customers (but only with the government’s approval and control).

Zhurong continues south, inspecting dunes

10:40 am

Zhurong's travels as of July 31, 2021

The Chinese science team for their Zhurong Mars rover released new images yesterday, including a map showing the rover’s present position.

The new images and location has confirmed that the white streaks seen in orbital pictures are small dunes of sand blown by the thin Martian wind.

The map to the right, created using their map but annotated and providing a wider context, shows their present location relative to the lander and surrounding terrain. So far the rover has traveled about 1,900 feet, about 1,000 feet per month. Since it seems to be operating as planned, I expect China will extend the mission once it completes its nominal three-month tour in about two weeks.

At that travel pace there is much of interest that is within the rover’s range. I expect they are heading south partly because this brings them closer to their original landing site, which is an area they probably studied at length before landing. Whether they head to the largest crater, visible only partly on the image’s south edge, remains unclear.
