Did China test a hypersonic weapon in August?

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 Earth observation satellite

8:37 am

China today successfully launched an Earth observation satellite using its smallsat Kuaizhou-1A rocket, the first launch of this quick response rocket since a failure in November 2020.
The satellite is supposedly for commercial use, but little information has been released about it and its constellation.

The leaders in the 2021 launch race:

33 China
23 SpaceX
15 Russia
4 Northrop Grumman

The U.S. still leads China 34 to 33 in the national rankings, with these numbers changing in a few hours should ULA successfully launch Landsat 9 using its Atlas-5 rocket.

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.
