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

11:21 am

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

9:35 am

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

9:14 am

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.

The launch site was in the interior of China, and for certain dumped its first stage onto that interior.

The leaders in the 2022 launch race:

37 SpaceX
33 China
11 Russia
6 Rocket Lab

SpaceX and China complete launches

12:51 pm

Two launches have just occurred in the 2022 launch race. First, SpaceX today successfully launched another 53 Starlink satellites, using its Falcon 9 rocket.

The first stage successfully landed on its drone ship in the Atlantic, completing its ninth flight.

China in turn used its Long March 2D rocket to launch three military reconnaissance satellites, at what was the early morning hours of August 20, 2022, China time. The launch path took the rocket over China’s interior as well as Taiwan, with the first stage crashing somewhere in China.

The leaders in the 2022 launch race:

37 SpaceX
31 China
11 Russia
6 Rocket Lab
5 ULA

American private enterprise still leads China 52 to 31 in the national rankings, and the entire world 52 to 49. The 52 launches so far this year is now the fifth best total for the U.S. since the launch of Sputnik in 1957.

China’s radar ship finally docks in Sri Lanka

9:00 am

Despite objections by India and an initial refusal by the Sri Lanka government to allow a Chinese military communications/radar ship to dock at one of Sri Lanka’s ports, the ship was finally allowed to dock yesterday.

Sri Lanka, which needs the support of both India and China as it struggles with its worst economic crisis in decades, initially granted the ship permission for a five-day replenishment stay in Hambantota, from Aug. 11.

It later asked China to delay the vessel’s arrival, citing the need for more consultations.

Yuan Wang 5 will now berth for only three days to stock up on fuel, food and other essentials, said an official at the port who declined to be identified as he is not authorised to speak to the media.

The ship is used by China to track satellites, rockets, and missiles, both its own and other nations.

Sri Lanka is caught between a rock and a hard place. The country is bankrupt, its citizens facing starvation due to the previous government’s imposition of numerous green environmental policies that destroyed its agriculture industry. It has also taken aid from both India (providing military hardware) and China (which built the port and holds a 99-year lease to operate it), and neither looks kindly at the other.

Russia and China complete launches

8:45 am

Both Russia and a pseudo-commercial Chinese company today completed launches.

Russia used its Soyuz-2 rocket to launch a military reconnaissance satellite for Iran, along with 16 Russian smallsats. The rocket was originally going to launch a South Korean satellite, but that launch was cancelled due to Russia’s invasion of the Ukraine.

In China, the pseudo-company Galactic Energy used its four-stage Ceres-1 rocket to place three Earth observations satellites into orbit. Because three of the rocket’s four stages use solid rocket motors, they were likely reworked from military applications. Thus, Galactic Energy does nothing without the full approval and supervision of the Chinese government. It might have been funded privately, and focused on making profits, but it really owns nothing it builds.

Nonetheless, this was its third successful orbital launch, making it the most successful of these Chinese pseudo-companies. It is also developing a Falcon 9 clone rocket dubbed Pallas-1, which it hopes to launch next year.

The leaders in the 2022 launch race:

34 SpaceX
29 China
11 Russia
6 Rocket Lab
5 ULA

American private enterprise still leads China 49 to 29 in the national rankings, and the entire world combined 49 to 47. A SpaceX Falcon 9 launch later today should strengthen this lead again.

Sri Lanka blocks docking of Chinese spy ship as requested by India

11:47 am

The new Sri Lankan government, at the request of India, has rescinded the permission granted by the previous government that would have allowed a Chinese satellite tracking ship to dock at one of its ports.

In a written request, the Sri Lanka Foreign Ministry told the Chinese Embassy in Colombo not to go ahead with the visit, said an official involved in the process. “The Ministry wishes to request that the arrival date of the vessel Yuan Wang 5 in Hambantota to be deferred until further consultations are made on this matter,” the request says.

Sri Lankan President Ranil Wickremesinghe assured political leaders on Friday that the visit will not go ahead as planned.

The previous government, recently overthrown by a citizen revolt because of its green policies that produced starvation and bankruptcy throughout the nation, had agreed to the docking, changing years of cooperation with India. Apparently the new government has decided to renew that Indian alliance.

India in turn wishes to limit China’s ability to spy on its own satellites and operations in space.

China launches “reusable experimental spacecraft”

4:02 pm

According to the official Chinese press, China today successfully used its Long March 2F rocket to place into orbit a “reusable experimental spacecraft.”

To say the information provided was terse is to be extravagant. This is it:

After a period of in-orbit operation, the spacecraft will return to its scheduled landing site in China. It will test reusable technologies and in-orbit service technologies as planned during its flight, providing technological support for the peaceful use of space.

It appears, based on the size of the rocket, that this spacecraft is likely a copy of Boeing’s X-37B.

The leaders in the 2022 launch race:

33 SpaceX
28 China
10 Russia
6 Rocket Lab
5 ULA

The U.S. still leads China 48 to 28 in the national rankings, and the entire world combined 48 to 45.

These numbers should change within the next half hour, as SpaceX is about to launch another rocket.

China launches three satellites with Long March 4B rocket

11:41 pm

China early on August 4, 2022 (China time) successfully placed three satellites in orbit, including a climate satellite it claims will do “carbon monitoring, survey and monitoring of terrestrial ecology and resource, major national ecological projects monitoring and evaluation.” No information at all was released about the other two satellites, both of which were probably cubesats.

This launch actually occurred prior to the Electron launch from Rocket Lab.

Today’s Twitter links

11:07 am

Today I am beginning a new mid-day feature on Behind the Black, thanks to the effort of reader Jay, who has recently been acting as a stringer by sending me new stories he finds on Twitter. I don’t do Twitter, so his help has been very much appreciated.

Most of these Twitter stories however do not merit a full post. Most are usually just interesting images, or PR updates from companies and space agencies announcing future events. Up to now I check them out, and then file them away. I decided we might as well post them each day, all at once, in a single post. Jay has agreed to gladly help make this happen.

So, let’s begin:

It is unknown how much information China will release much about this launch. Stay tuned.

I will only believe Blue Origin has delivered a flightworthy engine to ULA when ULA actually begins installing that engine on a Vulcan rocket. Until then, I view everything Blue Origin posts on Twitter on this subject to be nothing more than empty air.

Long March 5B pieces crash near villages in Malaysia and Indonesia

8:56 am

Several days after the July 30th uncontrolled de-orbit of China’s Long March 5B core stage locals in both Malaysia and Indonesia are finding large sections, some of which apparently fell close to villages.

A charred ring of metal about five metres in diameter was found on Sunday in Kalimantan, Indonesia, according to a Malaysian news outlet. Jonathan McDowell, an astrophysicist at the Harvard-Smithsonian Center for Astrophysics, said the metal appeared to be the exact size of the Chinese rocket’s core stage.

…“It looks like the end cap of a rocket stage propellant tank,” he said. “There’s no doubt in my mind that it’s from the rocket … it’s in the right place at the right time and looks like it is from the right kind of rocket.”

The article at the link also describes several other incidences, including one in which two families were evacuated when a piece landed near their home. I have embedded the video of one news report below, showing several of these impacts, many of which which apparently hit the ground hard enough to create craters several feet deep.

The article contains a big error, stating “there was no international law” forbidding the uncontrolled crash of such debris, but this is false. The Outer Space Treaty requires all nations to take action to avoid such incidents, and makes them liable to any damage. China is violating this treaty with every Long March 5B launch.

China’s Tiangong-3 space station, as seen from the ground

9:37 am

Tiangong-3 in orbit on July 29, 2022

The screen capture to the right was taken by a very short ground-based telescopic movie of China’s Tiangong-3 space station on July 29, 2022. I have labeled it to indicate the various parts of the station, including the new large module, Wentian, that launched to the station on July 24, 2022.

In my original post, I had mislabeled the sections. I have now corrected the image. Thanks to reader Jay for pointing out my error.

Tianhe is the original core module of the station. At present Wentian is in the forward port, so that it and Tianhe lie in a straight line. At some point shortly before the October launch of the next module, Mengtian, they will likely move it 90 degrees to its permanent port to one side, so that Mengtian can dock with the front port where Wentian now sits.

Mengtian will then be shifted 90 degrees to its permanent port on the opposite side of Wentian. At that point the station will form its planned final T-shape configuration.

This dance of spacecraft is necessary to keep the station as balanced as possible to aid in attitude control.

Long March 5B stage falls to Earth near Malaysia

12:04 pm

New data now suggests that the core stage of China’s Long March 5B rocket that it launched on July 24th has crashed to Earth somewhere off the coast of the island of Borneo, Malaysia.

As of writing, there is no indication that any debris hit land, though this could change.

In violation of the Outer Space Treaty, China very clearly has done nothing to upgrade the Long March 5B since it dumped a core stage uncontrolled last year. It very clearly can do nothing to prevent this from happening in October, when the Long March 5B lifts off again to carry into orbit the last planned module for the Tiangong station.

In other words, China cannot be relied upon to honor any treaty it signs. It signs the treaty, but then willfully ignores it if it thinks that is to its best interest.

Long March 5B stage reentry window narrowed to two hours

8:50 am

Long March 5B impact prediction

The Aerospace Corporation has now narrowed the window in which the out-of-control core stage of China’s Long March 5B rocket will crash back to Earth to about two hours, centered over the Pacific west of the United States at in the early morning of July 31st.

China appears to have dodged a bullet once again. The window is now only a little more than one orbit long, so we now know the impact point for the five to nine tons that will survive re-entry is mostly over water.

Long March 2D launches two military satellites for China

Long March 5B core stage crash window narrows to 12 hours

10:08 am

Predicted re-entry as of July 29, 2022

The Aerospace Corporation has now narrowed its predicted window for the uncontrolled re-entry of the core stage of China’s Long March 5B, launched on July 24th, to twelve hours, centered over southeast China in the early morning hours of July 31st.

The window still covers almost all inhabitable places on Earth. It will also narrow considerably in the next 24 hours, though not enough to make a reliable precise prediction until just prior to re-entry.

Just remember: China will repeat this farce in October, when it launches the next module to its Tiangong space station.

Update on Long March 5B core stage crash prediction

8:44 am

Prediction of Long March 5B crash

The Aerospace Corporation today adjusted its prediction for the uncontrolled crash of the core stage from the Long March 5B rocket that China launched on July 24th.

According to the new prediction, the core stage will return to Earth during a 32 hour period centered on the early morning hours of July 31st above the Middle East.

The map to the right shows this. As you can see, at present the uncertainty of the prediction means the core stage could still crash almost anywhere.

That China has still done nothing to adjust the stage’s orbit now almost certainly confirms it can do nothing. This further confirms that in the year-plus since its last Long March 5B launch in May ’21, it did nothing to fix this fundamental problem. Moreover, this is the rocket’s third launch, all of which involved a core stage crashing uncontrollably. Each launch was thus a direct violation of the Outer Space Treaty, of which China is a signatory.

Another Long March 5B launch is scheduled for later this summer, to launch the last planned module to China’s Tiangong space station. Expect another violation of the treaty then as well.

China launches new rocket

9:06 am

The new colonial movement: The Chinese Academy of Science today successfully completed the first launch of Lijian-1, a new four stage solid fueled rocket, placing six satellites into orbit.

The Chinese state press announcement is here. I am using the name of the rocket from this source.

The rocket is an upgrade of a “road-mobile” ICBM, and can place two tons into orbit, making it the largest solid-fueled rocket in China’s arsenal of rockets. It launched from a pad built especially for it at China’s interior Jiuquan spaceport, which means it dumped its first, second, and maybe its third stages on Chinese territory.

Tentative crash date for Long March 5B core stage: July 31st

8:56 am

Predicted crash path of Long March 5B core stage
Click for full image.

Engineers from the Aerospace Corporation have now made the first preliminary calculations and determined that the core stage of China’s Long March 5B rocket that launched July 24th will crash to Earth uncontrolled on July 31, 2022, give or take one day.

The map to the right, reduced to post here, shows all the orbits during that 48 hour period. Note that, except for most of Europe, almost all the high population regions of the globe are in the crash zone.

This prediction is very tentative, and will change as the core stage’s orbit evolves in the next few weeks. It also could change entirely if China has updated the rocket’s engines so they can be restarted at least once to de-orbit the stage properly, as it has hinted it could do. If however the orbit begins to decay without any action by China, then we will know those hints were lies, and that China is once again violating the Outer Space Treaty by acting with willful negligence to threaten harm to others with one of its launches.

Long March 5B core stage from July 24th launch remains in orbit

8:50 am

According to data from the U.S. Space Command, the core stage of the Long March 5B rocket used to launch China’s next large module for its Tiangong space station is still in orbit, with no indication yet that China has the ability to safely de-orbit it over the ocean in a controlled manner.

From Jonathan McDowell’s Twitter feed:

Two objects cataloged from the CZ-5B launch: 53239 / 2022-085A in a 166 x 318 km x 41.4 deg orbit, 53240 / 2022-085B in a 182 x 299 km x 41.4 deg orbit. Orbital epoch of ~1200 UTC confirms that the inert 21t rocket core stage remains in orbit and was not actively deorbited.

In all previous Long March 5B launches the core stage reached orbit, deployed its payload, and then crashed back to Earth uncontrolled a few weeks later because its engines could not be restarted. Since it is large, pieces hit the ground, but fortunately nothing landed in habitable areas. In one case however had the return occurred fifteen minutes earlier it would have landed in the New York City metropolitan area.

There were comments made during the launch countdown by Chinese officials suggesting the stage’s engine can now be restarted to allow it to be de-orbited properly, but if so there is as yet no indication that this has happened. If anything, the presence of these objects in orbit suggest otherwise.

It is also possible Chinese engineers are doing further orbital tests with both objects, and will de-orbit them properly in the next week or so. That China conducted a series of static fire tests of this stage’s engines prior to launch strongly suggested that they can now control its re-entry.

Since China won’t say, however, we can only wait and watch.

Tiangong-3 station, when completed

The new colonial movement: China on July 24, 2022 (China time) has successfully used its Long March 5B rocket to put into orbit its Wentian module, the next large section that will dock with the Tiangong station in the next day or so.

According to one announcer, the core stage will not crash to Earth in an uncontrolled manner, as in previous Long March 5B launches. However, this is China, and his statement cannot be taken at face value. We shall find out in the coming days if this is so, or whether the core stage will be a threat to habitable areas as its orbit decays.
