China launches three astronauts to its space station

4:23 pm

Earlier today China successfully launched a three-person crew to its Tiangong-3 space station, its Long March 2F rocket lifting off from its Jiuquan spaceport in the northwest of China.

No word on where the four strap-on boosters, the payload fairing, the core stages, and the upper stage crashed inside China, using very toxic hypergolic fuels. This new crew will replace the present crew, who are completing a six-month tour. The new crew will complete a similar-length mission.

The leaders in the 2024 launch race:

42 SpaceX
17 China
6 Russia
5 Rocket Lab

American private enterprise still leads the rest of the world combined in successful launches 49 to 29, while SpaceX by itself still leads the rest of the world, including other American companies, 42 to 36.

An abandoned module from one of China’s manned capsules burns up over California

9:29 am

The orbital module of China’s Shenzhou-15 manned capsule, launched with three astronauts in November 2022 and then abandoned in orbit when those astronauts returned to Earth in the spring of 2023, burned up over southern California yesterday.

The fall created a blazing fireball witnessed by people from the Sacramento area all the way down to San Diego, according to the American Meteor Society (AMS). As of Tuesday afternoon, 81 people had reported sightings of the event to the AMS.

It is unlikely, though not impossible, that any pieces hit the ground. The module is considered small enough to be destroyed during descent. Nonetheless, its uncontrolled re-entry highlights China’s general irresponsibility when it comes to space junk. For example, the Russia Soyuz capsule has a similar design, but based on history Russia has for decades routinely controlled the de-orbit of its abandoned orbital module so that it does not come down over land.

During landing Shenzhou’s single parachute appeared damaged

10:01 am

A closer look at imagery during the descent by parachute of China’s manned Shenzhou capsule, bringing three astronauts back from Tiangong-3 after a five month mission on October 31, 2023, shows that the capsule’s single parachute had a ripped hole.

In some of the footage, a patch of blue sky can be seen through the red-and-white-banded parachute. Inside the capsule were Shenzhou 16 mission commander Jing Haipeng and crewmates Zhu Yangzhu and Gui Haichao — the latter pair returning to Earth after their first mission to space.

Such a sizable hole, which was visible before a white cloud of vented propellant left the Shenzhou capsule, has not been reported during earlier missions. It did not, however, seem to affect operations.

The landing however was very rough, with the capsule tumbling several times after hitting the ground.

Considering that China presently as three astronauts on Tiangong-3 that have to come home in their own Shenzhou capsule, using this same parachute system, finding out what happened seems imperative. Developing its next generation larger capsule, which will return using three parachutes, also appears essential.

Chinese crew completes five-month mission on Tiangong-3 after return to Earth

8:32 am

The new colonial movement: A three-man Chinese crew successfully landed today in north China in their Shenzhou capsule, completing a five-month mission on the Tiangong-3 space station.

The full mission length was 154 days. China claims that one of the astronauts was a civilian, but that really means nothing considering the security required to participate in these missions.

The crew that has taken over on Tiangong-3 are expected to do a mission of comparable length, probably pushing the length to six-months.

China launches new three-man crew to its Tiangong-3 space station

9:02 am

The new colonial movement: China today successfully used its Long March 2F rocket to place a Shenzhou manned capsule into orbit, carrying a new three-man crew to its Tiangong-3 space station and lifting off from its Jiuquan spaceport in northwest China.

Though relatively little specific information about the crew’s mission has been revealed, it is expected they will do a six month mission, as have previous crews, and conduct spacewalks and maintenance on the station. Meanwhile, the present crew on board will spend about a week transferring duties to the new crew, and then return to Earth after completing its own six-month mission.

No word on where the Long March 2F first stage and its four side boosters crashed in the interior of China, all of which use toxic hypergolic fuels.

The leaders in the 2023 launch race:

76 SpaceX
48 China
13 Russia
7 Rocket Lab
7 India

American private enterprise still leads China 88 to 48 in successful launches, and the entire world combined 88 to 76. SpaceX by itself is now tied at 76 with the rest of the world (excluding American companies).

Tianzhou unmanned freighter completes month-long free flight, re-docks with Tiangong-3

9:30 am

Engineers today successfully re-docked a Tianzhou unmanned freighter to China’s Tiangong-3 space station after 33 days flying in formation with the station.

As is usual, China released no information about the reasoning behind this free flight, though some reasons are obvious. The station has two docking ports, and during that 33-day time period the station also completed a crew swap, with one Shenzhou capsule docking with three new astronauts while the previous crew and its Shenzhou capsule was still docked. The Tianzhou freighter had to undock to provide a port during this time period for the two manned capsules.

This formation free flight and docking was also likely testing the kind of routine maneuvers China plans to do when it launches its Hubble-class optical space telescope next year. That telescope will fly freely near the station during most of its operations. For maintenance and repair however it is my understanding that it will be brought back to the station and docked with it. The just completed independent flight of the Tianzhou freighter demonstrated this capability.

Three astronauts return to Earth safely from China’s Tiangong-3 space station

9:49 am

After completing six months in space on China7s Tiangong-3 space station, three astronauts safely returned to Earth yesterday, with their Shenzhou capsule touching down in inner Mongolia.

This mission was the first full six month mission on the station. During their mission they completed four spacewalks. Though little was published about what was accomplished on those EVAs, it is likely it involved completing the construction of the station as well as installing some exterior experiments.

Chinese launch yesterday set record for number of humans in space

8:59 am

The launch yesterday of three Chinese astronauts to that country’s Tiangong-3 space station established a new record, seventeen, for the number of humans in space.

The launch of the next crew to China’s Tiangong space station late Monday (U.S. time) added three astronauts to the population of humans in space, which reached a record number of 17 people in orbit — six Chinese citizens, five Americans, three Russians, two Saudis, and one Emirati astronaut.

The arrival of Chinese astronauts Jing Haipeng, Zhu Yangzhu, and Gai Haichao in space following their launch atop a Long March rocket broke the previous record of 14 people in orbit at one time.

Meanwhile, the four-person crew of the commercial AX-2 mission to ISS, has undocked from ISS, with SpaceX’s Freedom capsule expected to splashdown in the Gulf of Mexico at 11:09 pm (Eastern) tonight.

China sends a new crew to its Tiangong-3 space station

7:31 pm

Using its Long March 2F rocket, China today (May 30th in China) sent a new three-man crew to its Tiangong-3 space station for a five month mission.

The launch was from the Juiquan spaceport in the interior of China, so both the four side strap-on boosters as well as the core stage crashed somewhere in China. No word of any damage or injuries.

The Shenzhou capsule is expected to dock with the station about six hours after launch. The old crew’s stay will overlap with this new crew for a short time before returning to Earth.

The leaders in the 2023 launch race:

35 SpaceX
20 China
8 Russia
5 Rocket Lab

American private enterprise still leads China 40 to 20 in the national rankings, and the entire world combined 40 to 36. SpaceX alone now trials the rest of the world combined 35 to 36, but trails the entire world including American companies 35 to 41.

China unveils next Shenzhou launch date and crew to its space station

9:07 am

China today revealed the next three-man crew to occupy its Tiangong-3 space station, with a planned launch in a Shenzhou crew capsule targeting May 30, 2023, Chinese time.

Because of time differences, that launch will occur tonight at 6:28 pm tonight, Pacific time. The rocket will be a Long March 2F taking off from China’s western interior Jiuquan spaceport. The rocket’s lower stages will therefore crash somewhere in China.

The crew will remain on board the station for five months, and with one astronaut the first Chinese to fly in space four times.

China sets new annual record with launch of manned Shenzhou-15 to space station

9:02 am

China today successfully used its Long March 2F rocket to launch three astronauts on a six month mission to its Tiangong-3 space station, setting a new annual national record for launches in a single year.

China’s previous high of 52 successfully launches was achieved last year. This launch, with about five weeks left in the year, is its 53rd in 2022.

This mission will also be the first on Tiangong-3 where there will be an overlap of two crews, with six people occupying the station for a short while.

The leaders in the 2022 launch race:

54 SpaceX
53 China
20 Russia
9 Rocket Lab
8 ULA

The U.S. still leads China 78 to 53 in the national rankings, while trailing the rest of the world combined 83 to 78.

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

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’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 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.

Long March 2F booster that launched astronauts lands on public road in China

12:56 pm

Long March 2F strap on booster after crashing onto public road
Click for full image.

One of the four strap-on boosters used to launch three astronauts to China’s new space station on June 16th ended up landing on a public road in China.

The photo to the right, uploaded at this twitter feed, shows the booster. The parachute cords at its top explain why it is so relatively undamaged. The Chinese are apparently experimenting with parachutes to slow and maybe even control its descent. They might even be planning to catch the stage before it hits the ground, using a plane or helicopter, as both ULA and Rocket Lab hope to do with their Vulcan and Electron rockets.

Of course, we do not know this, as the Chinese tell us nothing.

Note that the hypergolic fuels, such as the hydrazine used in this booster, are extremely toxic. The person who took this picture is in very great danger, even if he or she does not know it.

Potential routes of hydrazine exposure include dermal, ocular, inhalation and ingestion.

Hydrazine exposure can cause skin irritation/contact dermatitis and burning, irritation to the eyes/nose/throat, nausea/vomiting, shortness of breath, pulmonary edema, headache, dizziness, central nervous system depression, lethargy, temporary blindness, seizures and coma. Exposure can also cause organ damage to the liver, kidneys and central nervous system. Hydrazine is documented as a strong skin sensitizer with potential for cross-sensitization to hydrazine derivatives following initial exposure.

Not that the Chinese government really cares. They have been dumping these boosters on their own people for decades, and only recently have apparently begun to look into ways of controlling their descent.

Manned Shenzhou capsule docks with Tianhe

9:53 am

China’s manned Shenzhou capsule early this morning successfully docked with the Tianhe module of that nation’s new space station.

The three astronauts on board will spend the next three months doing work in connection with the assembly of that station. Though this was the first Chinese manned mission in five years, the pace is expected to pick up in the next year.

Eight more launches will be required to finish construction of the space station, Chinese officials have said. Two will loft “lab modules” that will attach to Tianhe, forming the final T-shaped station. The assembly phase, which is expected to wrap up by the end of 2022, will also include three more cargo launches and three additional crewed missions.

Chinese astronauts successfully launched into space

6:55 pm

The new colonial movement: Using its Long March 2F rocket China tonight (June 17th in China) successfully launched three astronauts into orbit on their Shenzhou manned capsule for a planned three month mission to the first module of their new space station.

The most recent update as I post this:

Chinese mission control has confirmed today’s launch was a success, placing the Shenzhou 12 capsule into an orbit ranging in altitude between 120 miles (220 kilometers) and 208 miles (335 kilometers). Docking with the Tianhe core module is expected in approximately six hours. The rendezvous will be fully automated.

No word on where the four strap-on boosters and core stage landed within interior China.

The leaders in the 2021 launch race:

18 SpaceX
17 China
8 Russia
3 Northrop Grumman

The U.S. still leads China 26 to 17 in the national rankings, and will add to that lead if a planned SpaceX launch tomorrow goes as planned.

First manned mission to new Chinese space station to launch June 17th

9:19 am

The new colonial movement: China yesterday announced that the first manned mission to its new Chinese space station will launch tomorrow, June 17th, carrying three astronauts to the station’s Tianhe core module launched earlier this year.

One day before launch, China finally confirmed unofficial reports that it will launch the first crew to its new space station module, Tianhe, on June 17 Beijing Time (June 16 Eastern Daylight Time). It is China’s first human spaceflight launch in 5 years. The three men will stay aboard Tianhe for three months, the longest time in orbit for any Chinese crew.

During the three month mission the astronauts will do at least one spacewalk to likely deploy solar panels and other equipment preparing Tianhe for later modules.

The announcement also included statements by Russia that it has agreed to send Russian astronauts to the station at some point in the future.

No word on whether China will broadcast the launch live.

China rolls rocket to launchpad for first manned mission to station

8:39 am

The new colonial movement: China yesterday moved to the launchpad the Long March 2F rocket it will use to launch the first three astronauts to occupy its new space station.

The first element of the complex, the Tianhe core module, launched April 28 aboard a heavy-lift Long March 5B rocket, China’s most powerful launch vehicle. An unpiloted cargo ship, named Tianzhou 2, launched May 29 and docked with the Tianhe core module eight hours later, delivering fuel, food and spacesuits for the Shenzhou 12 astronauts.

The Shenzhou 12 mission will last about three months, the longest stay in space to date by Chinese astronauts. Shenzhou 12 will be China’s seventh crewed spaceflight since 2003.

Chinese officials have not announced the launch date for the Shenzhou 12 mission, but rockets for China’s last three crewed spaceflights rolled to the pad at Jiuquan about a week before liftoff. That suggests the launch could occur around June 16 or June 17.

As this launch will be from a spaceport in the interior of China, it will dump its first stage boosters on land.

During that three month mission the three astronauts will likely do several spacewalks to deploy solar panels and other equipment on the exterior of the Tianhe module, preparing it for later modules as well as the next manned mission, scheduled for October and planned to last six months.

Prototypes of China’s core space station module and new manned spacecraft arrive at launch site

9:06 am

The new colonial movement: Prototypes of China’s core space station module and its new upgraded manned capsule have been delivered to the Long March 5B launch site.

The space station module will be used to test the installation and launch procedures for launching the actual module on the Long March 5B rocket. The manned capsule will be sent into orbit unmanned this spring on the Long March 5B to test both the rocket and the capsule, prior to human operations. This detail from the short article however is worth noting:

The new-generation manned spacecraft is 8.8 meters long and has a takeoff weight of 21.6 tonnes. It will be used for transporting crew to the space station and to conduct China’s future manned lunar missions.

Apparently in upgrading its Shenzhou manned spacecraft China has made it 0.3 meters longer and about four tons heavier. In fact, this manned ferry for getting to and from its space station is as heavy as a standard module used on both Mir and ISS. I could be wrong, but if this is the case they will require the Long March 5 or 5B for every manned flight. Since this rocket is large and expensive, it will be difficult to use it for maintaining a frequent launch pace, thus limiting the number of manned missions.

As I said, I could be wrong. Up until now I had assumed that a variant of the Long March 5 would be used to launch the station modules, and the smaller Long March 2F rocket used to ferry astronauts to it (as was done on all previous Chinese manned missions). This could still be the case.

If not, however, China’s space engineers have either put a limit on what they can achieve by overbuilding that manned capsule, or their government has made a major commitment to put a lot of tonnage into orbit. If the latter China’s space program is going to be quite competitive indeed.

China’s next manned mission

9:55 am

The competition heats up: The next Chinese manned mission will occur in the fall of 2016 and will have the astronauts remain in space for 30 days on a new space station launched during the summer.

After the astronauts have completed their flight, China will then launch their first unmanned cargo craft, dubbed Tianzhou-1, to dock with the station, using a new medium-lift rocket, Long March 7, which will get its first test flight this coming June.

New China manned vehicle under development

7:42 pm

The competition heats up: China has begun development of two versions of a second generation manned capsule.

Instead of the three-module arrangement of the current Shenzhou vehicle, the future Chinese crew vehicle will adopt a two-module arrangement, with a large inhabitable crew module at the front, and an uninhabitable cylindrical-shaped service module at back. The size of the re-entry vehicle will be twice of Shenzhou’s, capable of accommodating up to six crew members. A docking port and its associated docking sensors are fitted to the front-end of the crew module. The spacecraft can be fitted with two different service modules, with different propulsion systems and propellant capacities.

In other words, rather than copy and upgrade the design of the Russian Soyuz, as they did with their Shenzhou capsule, they will copy and upgrade the American Apollo capsule.

The decision by China to launch their next Shenzhou manned capsule unnamed has made at least one China space expert worried.

7:15 pm

The decision by China to launch their next Shenzhou manned capsule unmanned has made at least one China space expert worried.

Why the sudden change? It seems clear that there must be technical issues at work, and they must be fairly serious. Statements in the Chinese media hint at performing tests on the small tunnel connecting the Shenzhou spacecraft to the Tiangong module after docking. If we decode the typically vague reportage, it seems fair to assume that there could be some sort of technical problem with the pressurization of this tunnel. This problem could have been exposed during the Shenzhou 8 docking.
