China launches classified satellites for military remote sensing

10:27 pm

China today successfully launched a set of classified satellites (number classified) for doing military remote sensing, its Long March 6 rocket lifting off from its Taiyuan spaceport in north China.

As usual, China’s state-run press released little information about the satellites, the launch, or where the rocket’s core stage and four strap-on boosters crashed inside China. The report did state the Long March 6 was “modified,” but did not detail how. One wonders if China has done something to improve the rocket’s upper stage, which reaches orbit and has had a tendency to break up shortly thereafter, creating large clouds of space junk.

The leaders in the 2025 launch race:

55 SpaceX
24 China
5 Rocket Lab
5 Russia

SpaceX still leads the rest of the world in successful launches, 55 to 41.

China launches six technology test satellites

9:50 pm

China today successfully placed a set of six technology test satellites into orbit, its Long March 6 rocket lifting off from its Taiyuan spaceport in northeast China.

No word on where the rocket’s lower stages and four strap-on boosters crashed inside China. Furthermore, the upper stage of the Long March 6 rocket, which reaches orbit, has a history of breaking up and creating clouds of space junk. We have no assurance from China whether they have fixed this issue.

The leaders in the 2025 launch race:

43 SpaceX
20 China
5 Rocket Lab
5 Russia

SpaceX still leads the rest of the world in successful launches, 43 to 35. (Note: this last number is corrected from the previous update, which was one number short.)

Another record-setting launch day worldwide

9:19 am

In what might be a record for the global launch industry, yesterday saw a total of four launches at four different spaceports worldwide.

That record might very well be matched today. Already three launches have already taken place, with one more scheduled.

First, India’s space agency ISRO successfully launched European Space Agency’s PROBA-XL solar telescope, its PSLV rocket lifting off from its Sriharikota spaceport on India’s eastern coast. This was India’s fourth launch in 2024.

Next, China launched what its state-run press merely described as a “group of satellites,” its Long March 6 rocket taking off from its Taiyuan spaceport in northern China. That state-run press also said nothing about where the rocket’s lower stages and four strap-on boosters crashed inside China. (UPDATE: More information about the payload can be found here. It appears to have been the third set of 18 satellites launched as part of China’s attempt to compete with Starlink.)

Then, SpaceX launched SXM-9, a new satellite for the constellation of the radio company Siruis-XM, its Falcon 9 lifting off from Kennedy in Florida. The first stage completed its nineteenth flight, landing on a drone ship in the Atlantic. As of posting the satellite had not yet been deployed.

If all goes as planned, the fourth flight today will be the first launch in more than two years of Avio’s Vega-C rocket, which has been grounded while the company redesigned and then redesigned again the engine nozzle of its upper stage. The launch is also one of the last that will be managed by Arianespace, which is giving up control to Avio over the next year. The live stream is here.

If successful, it will be the eighth launch worldwide in only two days, something that I am fairly certain has never been done before. In the past there simply weren’t enough independent entities and spaceports available to allow this number of launches in such a short period of time. What makes this record even more striking is that three of the eight launches were launched by one private American company, SpaceX.

The leaders in the 2024 launch race:

127 SpaceX
59 China
16 Russia
13 Rocket Lab

American private enterprise still leads the rest of the world combined in successful launches 146 to 89, while SpaceX by itself leads the entire world, including American companies, 127 to 108.

China launches three radar satellites

8:33 am

China today successfully launched three radar satellites, its Long March 6 rocket lifting off from Taiyuan spaceport in northeast China.

The news report from China’s English state-run press made believe this launch was only one satellite, in contrast to its Chinese language press. It also did not provide information on where the rocket’s first stage crashed within China, nor whether any upgrades have been done to the Long March 6’s upper stage to prevent it from breaking apart and scattering low Earth orbit with space junk, as has now happened four times previously.

The leaders in the 2024 launch race:

102 SpaceX
48 China
11 Russia
11 Rocket Lab

American private enterprise now leads the rest of the world combined in successful launches 119 to 71, while SpaceX by itself now leads the entire world, including American companies, 102 to 88.

China launches third batch of 10 satellites for proposed Starlink copycat constellation

8:51 am

China early this morning launched the third group of ten satellites for a proposed low-Earth-orbit internet constellation of nearly 6,000 satellites, proposed and built by a Chinese pseudo-company Geespace.

The company was created in 2018 and is backed by the Chinese automaker Geely. The Long March 6 rocket lifted off from China’s Taiyuan spaceport in northeast China. No word on where the rocket’s lower stages crashed.

The leaders in the 2024 launch race:

88 SpaceX
38 China
10 Rocket Lab
9 Russia

American private enterprise now leads the rest of the world combined in successful launches 103 to 57, while SpaceX by itself leads the entire world, including American companies, 88 to 72.

China successfully launches classified satellite

10:27 pm

China tonight (November 1, 2023 in China) successfully launched a classified satellite, its Long March 6 rocket lifting off from its Taiyuan spaceport in the north part of the country.

No video of the launch was released. Nor were any pictures. In addition, no information was released describing where the rocket’s first and second stages crashed. Both use kerosene and oxygen, so neither is as toxic as China’s other older rockets using hypergolic fuels, but China also does not make any apparent effort to control these crash landings.

The leaders in the 2023 launch race:

78 SpaceX
49 China
14 Russia
7 Rocket Lab
7 India

American private enterprise still leads China 90 to 49 in successful launches, and the entire world combined 90 to 78. SpaceX by itself is now tied with the rest of the world (excluding American companies) 78 to 78.

Two launches today, one by ULA and one by China

10:16 am

Today there were two successful launches. First China launched a remote sensing satellite using its Long March 6 rocket that lifted off from its Taiyuan spaceport in the south of China.

No word on where the rocket’s lower stages and four strap-on boosters crashed inside China.

Shortly thereafter, ULA used its Atlas-5 rocket to place a reconnaissance satellite into orbit for the National Reconnaissance Office (NRO), lifting off from Cape Canaveral.

For ULA, this was only its second launch in 2023. The leaders in the 2023 launch race are now as follows, with China’s total corrected:

63 SpaceX
42 China
12 Russia
7 Rocket Lab
7 India

In the national rankings, American private enterprise now leads China in successful launches 73 to 42. It also now leads the entire world combined, 73 to 67, while SpaceX by itself now trails the rest of the world (excluding American companies) only 63 to 67.

CORRECTION: Hat tip to reader John Foley (see his comment below), who noted that China’s total appeared to be one short. I went back and discovered I had missed a March 22, 2023 launch of a Kuaizhou 1A rocket from the Jiujian spaceport, placing four weather satellites in orbit. I have now added that launch to China’s total, and corrected the other numbers.

China launches classified experimental satellite

8:40 am

Using its Long March 6 rocket, China today launched what its state-run press called a “new experimental Earth-observation satellite,” lifting off its Taiyuan interior spaceport.

No word on whether the rocket’s first stage crashed near habitable areas, or whether it used parachutes to control its descent.

The leaders in the 2023 launch race:

41 SpaceX
24 China
8 Russia
5 Rocket Lab

American private enterprise still leads China in successful launches 46 to 24 in the national rankings, and the entire world combined 46 to 40, with SpaceX by itself still leading the rest of the world, excluding other American companies, 41 to 40.

Chinese upper stage disintegrates in orbit

10:21 am

A Chinese Long March 6 upper stage, launched in on November 11, 2022, has disintegrated into more than 350 in orbit and now pose a threat to other orbiting spacecraft.

The Long March 6A rocket launched from Taiyuan, north China, on Nov. 11, successfully inserting the Yunhai 3 environmental monitoring satellite into its intended orbit.

The upper stage of the rocket, however, apparently suffered a breakup event shortly thereafter. On Nov. 12, the U.S. Space Force’s 18th Space Defense Squadron (18SDS) reported that it was tracking at least 50 discrete pieces of orbital debris from the rocket body. Ongoing tracking from 18SDS, which focuses on space domain awareness, now states that the debris cloud has grown to 350 objects associated with the rocket stage.

Based on the data, it appears the break-up occurred because the stage had an explosive event. It could have been programed to fire its engine to quickly de-orbit it and something went wrong. Or not. The Chinese have not demonstrated much concern about such issues.

China launches environmental satellite

7:08 pm

Using its Long March 6 rocket, China early today launched what China’s state-run press claimed was an environmental satellite for “atmospheric and marine environment surveys, space environment surveys, disaster prevention and reduction, and scientific experiments.” Whether that is true is anybody’s guess.

The leaders in the 2022 launch race:

52 SpaceX
50 China
19 Russia
9 Rocket Lab
8 ULA

American private enterprise now leads China 75 to 50 in the national rankings, and trails the rest of the world combined 78 to 75.

FYI, posting is late today because today Diane and I were out hiking, having fun.

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

9:16 am

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.

China launches Landsat-type satellite using Long March 6

2:04 pm

China today successfully placed a Landsat-type satellite into a sun-synchronous orbit, using its Long March 6 rocket. From the link:

The Taiyuan Satellite Launch Center sits at an altitude of approximately 1,500 meters (4,920 feet) above sea level, its dry climate making it an ideal launch site for the Chinese space program. Unlike the Kennedy Space Center or the Guyana Space Centre, however, Taiyuan is located inland rather than on China’s eastern coast. This means spent rocket stages can crash-land near populated regions depending on the rocket’s flight trajectory.

Some recent flights of [Long March] rockets have featured parachutes and even grid fins mounted on the first stage boosters, presumably in an attempt to mitigate any collateral damage caused by falling debris. Friday’s launch did not see this type of hardware in place.

No word yet on where the first stage booster landed, or if it landed near habitable areas.

The leaders in the 2021 launch race:

40 China
23 SpaceX
18 Russia
4 Northrop Grumman
4 ULA
4 Europe (Arianespace)

China now leads the U.S. 40 to 36 in the national rankings. Its forty successful launches so far this year is the most by a single nation since Russia completed 49 in 1994.

This was also the 100th successful launch this year. Based on the number of planned launches presently scheduled,, that number could easily rise to more than 125, the most since the early 1980s.

China launches 5 military reconnaissance satellites

9:37 am

Using its Long March 6 rocket, China today successfully launched five military reconnaissance satellites.

This is China’s fourth successful launch in the past week.

Though this newer rocket’s first stage does not use toxic hypergolic fuels — China’s older rockets — that first stage still crashes in China after its job is done and it falls to Earth. No word on whether it landed near inhabited regions.

The leaders in the 2021 launch race:

22 China
20 SpaceX
11 Russia
3 Northrop Grumman

The U.S. still leads China 29 to 22 in the national rankings.

Argentinian smallsat company signs 90 satellite deal with China

9:14 am

An Argentinian smallsat company, Satellogic, has signed a 90 satellite launch deal with China.

Satellogic’s constellation seems likely to compete with the remote-imaging satellite constellations operated by San Francisco-based Planet and Seattle-based BlackSky. The company promises to remap Earth at 1-meter pixel resolution every week and dramatically reduce the cost of high-frequency geospatial analytics.

The deal is officially signed with a so-called private launch company in China dubbed China Great Wall Industry, but that company merely acts as an agent for a Chinese government space operation, China Aerospace Science and Technology Corp.

What this means however is that China’s launch rate is going to go even higher in the next few years.

Long March 6 launch a success

9:12 pm

The competition heats up: The first launch of China’s smallsat rocket Long March 6 was a success on Saturday, putting 20 satellites into orbit.

This rocket is part of a new family of Chinese rockets, modularly designed so that can be reconfigured depending on payload or mission. The big launch however will be next year, when they attempt the first test flight of the largest member of this family.

China to launch new rocket today

7:54 am

The competition heats up: With the expected first launch of China’s new Long March 6 rocket today, this report nicely outlines the status of the country’s rocket program.

Like Russia’s Angara and SpaceX’s Falcon, the new generation of Long March rockets are modular and use the same rocket engine. This has reduced cost and allows for faster assembly. The launch today is the maiden flight of the smaller member of this family. The key launch will be that of the larger Long March 5, scheduled for next year. Capable of putting 25 tons in orbit (five more than Proton), this is the rocket they plan to use to launch the modules for their full-sized space station.
