China launches its first asteroid sample return mission

China today successfully launched Tianwen-2, its first mission attempting to return a sample from a near Earth asteroid, its Long March 3B rocket lifting off from its Xichang spaceport in southwest China.

Video of the launch can be found here. The probe will take about a year to reach asteroid Kamo’oalewa, where it will fly in formation studying it for another year, during which time it will attempt to grab samples by two methods. One method is a copy of the touch-and-go technique used by OSIRIS-REx on Bennu. The second method, dubbed “anchor and attach,” is untried, and involves using four robot arms, each with their own drill.

Some data suggests Kamo’oalewa is possibly a fragment from the Moon, but that is not confirmed.

After a year studying Kamo-oalewa, Tienwen-2 will then return past the Earth where it will release its sample capsule. The spacecraft will then travel to Comet 311P/PANSTARRS, reaching it in 2034. This comet is puzzling because it has an asteroid-like orbit but exhibits activity similar to a comet.

As for the launch, there is no word where the Long March 3B’s lower stages and four strap-on boosters, all using very toxic hypergolic fuels, crashed inside China. It should be noted that the video I link to above was taken by an ordinary citizen watching from a hill nearby, bringing with him a group of children as well. Considering the nature of the rocket’s fuel (which can dissolve your skin if it touches you), China’s attitude is remarkably sanguine to not only drop these stages on its people, but to allow tourists to get so close to launches.

The leaders in the 2025 launch race:

65 SpaceX
31 China (with one more launch scheduled later today)
6 Rocket Lab (with one launch scheduled for today SCRUBBED)
6 Russia

SpaceX now leads the rest of the world in successful launches, 65 to 50.

China and SpaceX complete launches

Both China and SpaceX completed launches yesterday. First, China placed what its state-run press called “a data relay” satellite into orbit, its Long March 3B rocket lifting off from its Xichang spaceport in southwest China.

No word on where there rocket’s lower stages and four strap-on boosters crashed inside China. All use very toxic hypergolic fuels.

Next SpaceX launched 23 more Starlink satellites, including 13 configured for cell-to-satellite service, its Falcon 9 rocket lifting off from Cape Canaveral in Florida. The first stage completed its 20th flight, landing on a drone ship in the Atlantic.

The leaders in the 2025 launch race:

48 SpaceX
22 China

SpaceX now leads the rest of the world in successful launches, 48 to 37, with three more launches scheduled for later today. China will use its Long March 5B, its largest rocket, to launch a set of communications satellites, SpaceX will launch another set of Starlink satellites, and ULA will make its second attempt to launch Amazon’s first set of Kuiper internet satellites, the first launch scrubbed due to weather.

China launches another technology test communications satellite payload

China today successfully launched a test technology satellite for doing “multi-band and high-speed communication technology validation tests, possibly for future large internet/communications constellations, its Long March 3B rocket lifting off from its Xichang spaceport in southwest China.

No word on where the rocket’s lower stages and four strap-on boosters, all using very toxic hypergolic fuels, crashed inside China.

The leaders in the 2025 launch race:

SpaceX still leads the rest of the world in successful launches, 40 to 33.

Two more launches today

Since this morning’s launch by Rocket Lab, there have been two more launches. First, SpaceX placed another 27 Starlink satellites into orbit, its Falcon 9 rocket lifting off from Vandenberg in California.

The first stage completed its 24th flight, landing on a drone ship in the Pacific. This is presently SpaceX’s second most used booster, exceeded only by one that has flown 26 times.

Next China launched a communications satellite for use by its space station and other government space missions, its Long March 3B rocket lifting off from Xichang spaceport in southwest China. No word on where the rocket’s core stage and four side boosters, all using very toxic hypergolic fuel crashed inside China.

The leaders in the 2025 launch race:

35 SpaceX

SpaceX still leads the rest of the world in successfully launches, 35 to 27.

China launches classified communications test satellite

China yesterday successfully launched a classified communications satellite “to carry out multi-band and high-speed communication technology validation, its Long March 3B rocket lifting off from its Xichang spacesport in southwest China.

All we really know about this satellite is that it is part of series. Nor did China reveal where the core stage and four strap-on boosters of the rocket, which use very toxic hypergolic fuels, crashed inside China.

China and SpaceX complete launches

Two more launches today. First China launched a communications satellite into orbit, its Long March 3B rocket lifting off from its Xichang spaceport in the southwest of China. No word on where the rocket’s core stage and four side boosters crashed inside China. Nor has China released much information about the satellite itself.

Next SpaceX placed another 22 Starlink satellites, its Falcon 9 rocket lifting off from Vandenberg in California. The first stage completed its eleventh flight, landing on a drone ship in the Pacific.

The leaders in the 2025 launch race:

23 SpaceX
8 China

At this moment SpaceX’s 23 launches in 2025 is not far short of being twice as much as the 14 launches completed by rest of the entire world combined. It certainly is outpacing everyone else quite handily.

Strap-on booster of Long March 3B launched yesterday crashed next to home

Long March 3B
Long March 3B

One of the four strap-on boosters used by a Long March 3B rocket that was launched yesterday from the Xichang spaceport in southwest China ended up crashing right next to a home.

The TJS-14 satellite launched on a Long March 3B rocket from Xichang Satellite Launch Center on Thursday at 10:32 a.m. EST (1532 GMT; 11:32 p.m. local time). The satellite is safely on its way to geostationary orbit, but one of the rocket’s four strap-on side boosters fell to Earth in a populated area of Zhenyuan County in Guizhou province.

Security camera footage posted on the social media platform Sina Weibo captured the scene of two family members reacting to an explosion near their home that lit up the night sky. Fortunately, the booster, which exploded on impact, fell in what appeared to be hills above the house.

The video can be viewed here. While the booster apparently missed the house, any remaining hypergolic fuel in the booster posed a very serious health threat, especially if it was released as a gas. That fuel is extremely toxic, and can dissolve skin if it makes contact. I would expect that until a major clean-up occurred at the crash site, the people that lived in that home will have to evacuate.

China has said that it intends to replace all of its hypergolic-fueled rockets with liquid-fueled, and is expanding operations at its Wenchang coastal spaceport as well. When however these rockets stop launching from its interior spaceports remains unknown. It is likely in fact that toxic stages will continue to fall on the heads of Chinese citizens for years to come.

China and SpaceX complete launches

Both China and SpaceX successfully completed launches since last night.

First, China placed a classified technology communications test satellite in orbit, its Long March 3B rocket lifting off from its Xichang spaceport in southwest China. No further details about the satellite were released. Nor did China’s state-run press provide any information about where the rocket’s lower stages and four strap-on boosters, all using very toxic hypergolic fuels, crashed inside China. UPDATE: One of the four strap-on boosters crashed next to a home.

Then SpaceX this morning launched 23 more Starlink satellites, its Falcon 9 rocket lifting off from Vandenberg in California. The first stage completed its 23rd flight, landing on a drone ship in the Pacific.

China completes its first launch in 2025

SpaceX is no longer the only entity that has launched a successful orbital launch this year. Early today China successfully placed an “experimental” satellite into orbit, its Long March 3B rocket lifting off from the Xichang spaceport in southwest China.

No word on where the rocket’s lower stages, using very toxic hypergolic fuels crashed within China. As for the satellite, China’s state run press merely said that it “was built by its subsidiary Shanghai Academy of Spaceflight Technology and is tasked with verifying orbital refueling and life-extension technologies.”

China launches a communications test satellite

According to China’s uninformative state-run press, it today launched “a test satellite for communication technology,” its Long March 3B rocket lifting off from its Xichang spaceport in southwest China.

No other details about the satellite were released. Nor did the state-run press provide any information about where the rocket’s lower stages, using very toxic hypergolic fuel, crashed inside China.

As is usual for China, it is doing a lot of launches at the end of the year. Though weather might be a factor, I also suspect it is the ordinary “use-it-or-lose-it” symptom of a government-run communist society. Budgets are set for the year. Government agencies find that they better launch or they will lose that budgeted amount in the next year’s budget.

This might not apply to China but if so it would explain its strange end-of-year launch pattern.

China today successfully launched what its state-run press claimed was “high-orbit internet services satellite,” its Long March 3B rocket lifting off from its Xichang spaceport in southwest China.

No word on where the rocket’s lower stages and strap-on boosters crashed inside China. All use toxic hypergolic fuels.

As for the payload, this tweet from a independent reporter on China’s space program questions the claim that it is a communications satellite. Since China has told us nothing, we really know nothing. However, if it was really what its state-run press says it is, China would normally release a bit more information.

Launches by China and Russia

Earlier today both China and Russia successfully completed launches.

First, China launched a Chinese-built Pakistani communications satellite into orbit, its Long March 3B rocket lifting off from its Xichang spaceport from the southwest of China.

No real information was released about the satellite, or the fate of the rocket’s lower stages and four strap-on boosters, all of which use toxic hypergolic fuels and certainly crashed somewhere in China.

Next, Russia successfully launched a new Progress cargo ship to ISS, its Soyuz-2 rocket lifting off from Baikonur in Kazakhstan. The freighter will dock with ISS tomorrow. I have embedded video of the launch below, cued to T-30 seconds.

The rocket’s flight path took it over Kazakstan, Russia, and China, with drop zones for the lower stages in the first two. No word on whether the lower stages and four strap-on boosters crashed near habitable areas.

SpaceX and China complete launches

Two successful launches today, first from China and then from SpaceX.

First, China launched what it called a”high-orbit internet services” satellite into orbit, its Long March 3B rocket lifting off from its Xichang spaceport in southwest China. No word where the rocket’s four strap-on boosters or core stage crashed in China.

Then SpaceX launched another 23 Starlink satellites into orbit, its Falcon 9 rocket lifting off from Cape Canaveral. The first stage successfully completed its 11th flight, landing on a drone ship in the Atlantic.

The leaders in the 2024 launch race:

China launches two GPS-type satellites

China today successfully placed two more of its BeiDou GPS-type satellites into orbit, its Long March 3B rocket lifting off from its Xichang spaceport in the southwest of China.

This footage shows that the rocket’s core stage crashed near homes in China. No word on where the four strap-on boosters and second stage crashed. All use very toxic hypergolic fuels.

This launch continues China’s annual rush of launches at the end of the year. Since everything is owned and run by the Chinese government, one wonders if this pattern is because of the typical government mentality that requires agencies to rush to spend a lot at the end of each year so as to make sure their budgets are not cut.

Researchers confirm it was a Chinese rocket stage that impacted Moon in 2022

Impact, before and after
The crash site is the double crater in the
lower image.

Researchers have now confirmed that the unknown rocket stage that impacted the Moon in 2022 was from a Chinese rocket, a Long March 3B that launched China’s Chang’e-5 lunar sample return mission in November 2020.

“In this paper, we present a trajectory and spectroscopic analysis using ground-based telescope observations to show conclusively that WE0913A is the Long March 3C rocket body (R/B) from the Chang’e 5-T1 mission,” the researchers, led by Tanner Campbell, a doctoral student in the UA’s Department of Aerospace and Mechanical Engineering, wrote in a study that came out Thursday (Nov. 16) in the Planetary Science Journal. These two lines of evidence — how the object was moving and what it was made of — leave little doubt about WE0913A’s provenance, Campbell and his colleagues report.

The data, combined with the unusual double crater caused by the impact, also suggests that this stage had additional unknown equipment at its top, matching the mass of its engines at the bottom. Since the Chinese continue to deny it was their stage and have said nothing about it, we have no idea what that extra equipment might have been.

China’s Long March 3B rocket launches communications satellite

China last night successfully put a geosynchronous communications satellite into orbit, its Long March 3B rocket lifting off from its Xichang spaceport in southern China.

No word on where the rocket’s core stage, second stage, and four side boosters crashed inside China. All use extremely toxic hypergolic fuels, so anyone approaching any wreckage risks serious health issues.

China early today used its Long March 3B two-stage rocket (plus four strap-on boosters) to put a radar satellite into geosynchronous orbit, lifting off from its Xichang spaceport in southern interior China.

The orbit required the rocket to travel almost due east, which means the first stage and all four boosters crashed over China’s eastern heavily populated provinces, as shown on the map to the right. All use toxic hypergolic fuels. No word if the stages landed on any cities, as China’s communist government does without any qualms.

China tests parachutes on recent Long March 3B launch

During a May 17, 2023 launch of a Long March 3B rocket, China tested the use of parachutes to better control the descent and landing of the rocket’s boosters.

The system was used on a Long March-3B rocket carrying a BeiDou navigation satellite into orbit on May 17 from the Xichang Satellite Launch Center in Sichuan Province, according to the academy.

Developed by the academy, the parachute brought down the rocket boosters to a predetermined location, narrowing the range of the landing area by 80 percent.

Based on the limited information provided by China’s state-run press, it appears this system was only tested on the four strap-on boosters, not on the first stage core. Regardless, such a system, which appears to be a copy of the system Rocket Lab has been developing for the last four years, will significantly reduce the hazards to Chinese inhabitants who live in the drop zones of these rockets.

Note too that China previously tried to copy SpaceX’s grid fins. Apparently its engineers found it difficult if not impossible to reverse engineer that concept, so they apparently decided to try copying Rocket Lab’s parachute methods instead.

China’s Long March 3B puts another GPS-type satellite into orbit

China early on Wednesday, May 17, 2023 (China time) used its Long March 3B to successfully launch a GPS-type satellite, adding one more satellite to its constellation of similar satellites.

As the launch was from the Xichang Satellite Launch Center in the interior, the rocket’s core stage and four strap-on boosters crashed somewhere inside China. No word on whether they landed near habitable areas.

Philippines issues warning about Chinese rocket debris from launch

Flight path of Long March 3B
Click for full resolution image.

UPDATE: A tweet from China shows that the strap-on boosters of this rocket crashed near homes in China, though no one was hurt.

Original post:
—————–
The Philippine government issued a statement yesterday warning the public about possible debris from the December 29th launch by China of its Long March 3B rocket.

The Philippine Space Agency (PhilSA) is recommending precautionary measures related to expected unburned debris from the Long March 3B rocket scheduled for launch today between 12:33 PM and 01:10 PM Philippine time from the Xichang Satellite Launch Center in Xichang, Sichuan Province, China. Upon confirmation of planned launch dates, PhilSA immediately issued an advisory to all relevant government agencies on the estimated drop zone area and proposed the issuance of appropriate warnings on air and marine access.

Based on the Notice to Airmen (NOTAM) issued by the Civil Aviation Administration of China (CAAC) to the Civil Aviation Authority of the Philippines (CAAP), expected unburned debris, such as the rocket boosters and payload fairing, is projected to fall within a drop zone area located within the vicinity of Recto bank, approximately 137 kilometers from Ayungin Shoal and 200 kilometers from Quezon, Palawan. The unburned debris is designed to be discarded as the rocket enters outer space. While not projected to fall on land features or inhabited areas within the Philippine territory, falling debris poses danger and potential risk to ships, aircraft, fishing boats, and other vessels that will pass through the drop zone.

Though the drop zone avoided inhabited areas, it included regions where fisherman worked, and the flight path still flew over inhabited areas. The risk was extremely low, but it appears China also made no effort prior to launch to coordinate this situation with other governments, such as the Philippines. Its warning apparently arrived just before launch. Thus, there was risk that Filipino fisherman were in the drop zone at launch.

China’s Long March 3B rocket launches “experimental satellite”

I have embedded the English live stream below. A lot of Chinese propaganda (though not much different from a NASA broadcast). As I understand it, the launch window is instantaneous, so if there are any holds the launch will be scrubbed for the day.

More Chinese space junk crashes in India

It appears that debris from an upper stage of a Chinese Long March 3B rocket, launched in September ’21, fell in India on May 12, 2022.

Local media reported that the objects crashed with “loud thuds that shook the ground” in Gujarat. There were no casualties or property damage, according to The Indian Express. The crashed objects were all discovered within a 15-kilometer radius, and among them was a black metal ball weighing around five kilograms, the newspaper said.

Though the sources objects have not been identified with certainty, they look like inner tanks from a rocket, and the only object that reentered the atmosphere on this date and also had an orbit that crossed this part of India was the Long March 3B.

This is second time in less than a month that debris from an abandoned Chinese upper stage has crashed in India. Both are thought to have come from Long March 3Bs. More important, both now prove that China has no protocols when it launches these rockets to de-orbit the upper stages in a controlled manner.

Stay tuned for more Chinese space junk heading your way. In the next seven months it will launch two Long March 5B rockets, the large core stage of which reaches orbit. In all of the previous 5B launches, that stage — big enough to hit the Earth — then quickly fell back in an uncontrolled and unpredictable manner. Fortunately, each time it crashed in the ocean, though the May 2020 deorbit ended up with some debris landing near villages in Africa.

Recent tests of the 5B’s core stage’s engine have suggested that China might have redesigned it to allow it to be restarted, which would allow them to control its deorbit. This fact however has not been confirmed.
