China to expand Tiangong space station

9:10 am

Tiangong-2 station after expansion

The new colonial movement: At the 47th International Astronautical Congress in Baku, Chinese officials yesterday revealed that they intend to expand their Tiangong space station, almost doubling it in size.

The graphic to the right illustrates this, with the proposed new modules in magenta at the top.

“We will build a 180 tons, six-module assembly in the future,” Zhang said. Tiangong currently has three modules, each with a mass of around 22 tons.

A multi-functional expansion module with six docking ports will first be launched in the coming years to allow this expansion. This will dock at the forward port of the Tianhe core module. Full size modules can then be added to Tiangong. SpaceNews understands that the timeline for such launches is around four years from now. An expanded Tiangong would be just over a third of the mass of the roughly 450-metric-ton International Space Station (ISS).

The officials also said that they plan to add additional inflatable modules to the existing part of the station, as well as attachment points allowing for external experiments exposed to the environment of space.

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 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 successfully launches 1st cargo freighter to its space station

9:31 am

On May 29th China successfully launched the first Tianzhou cargo freighter to bring cargo the now-orbiting first module, Tianhe, of its under construction space station, docking there one day later.

They plan to launch the first crew of three to the station in June.
The leaders in the 2021 launch race:

16 SpaceX
14 China
8 Russia
2 Rocket Lab
2 ULA

The U.S still leads China 22 to 14 in the national rankings.

Sorry for the late posting, but I have been off on a cave expedition in a very remote area in Nevada. Needed a break from the news and work. Presently on the long drive home. Posting will resume at full speed later tonight.

China scrubs launch of station cargo freighter again

10:43 am

For the second time in two days China has scrubbed the launch of the first unmanned Tianzhou cargo freighter to the core module of its space station,

As before, the Chinese only said that the scrub was due to unstated “technical issues.”

They will likely try again tomorrow, but that is pure speculation. Without a more detailed report from China, we really have no idea what is happening.

China rolls out rocket for next space station launch

10:00 am

The new colonial movement: On May 15th China rolled out the Long March 7 rocket that on May 20th will carry the first Tianzhou cargo freighter to the already launched core module of its space station.

Tianzhou-2 will carry 4.69 tons of cargo in a pressurized segment and 1.95 tons of propellant, according to the China Manned Space Agency (CMSA).

Meanwhile, the core stage, dubbed Tianhe, has successfully completed its on-orbit checkouts and has placed itself in the right orbit for the arrival of Tianzhou.

If all goes right with this cargo mission, China is targeting a June launch for the station’s first three-man crew, who will attempt to stay at the station for three months.

Do not expect much information to be released by China during these missions. Like the Soviet Union of old, and as they have been doing routinely since their space program began to gear up in the past decade, they will only make periodic terse announcements, all of which will contain only the most superficial of information. Only much later will more be learned, usually many years after the fact when its news value has vanished and it only concerns historians and space buffs.

SpaceX launches 60 more Starlink satellites; China launches Tianhe station module

10:16 pm

Twas a busy evening. SpaceX successfully put 60 more Starlink satellites into orbit using its Falcon 9 rocket, with the first stage successfully completing its seventh flight, landing safely on the drone ship in the Atlantic.

China in turn successfully used its Long March 5B rocket to place in orbit the core module, dubbed Tianhe, of its planned space station. This is the first of eleven launches in the next two years to assemble the station’s initial configuration, including cargo and manned missions along the way.

The SpaceX live stream is at the link. I have embedded China’s English language live stream of the Tianhe launch below the fold. The launch is about 52 minutes in.

The leaders in the 2021 launch race:

12 SpaceX
10 China
7 Russia
2 Rocket Lab

The U.S. still leads China 17 to 10 in the national rankings.

The upcoming first launch of China’s space station

10:12 am

The Chinese Space Station

The new colonial movement: Later this month, on April 29th, China will use its Long March 5B rocket to launch the first module of its space station, dubbed Tianhe, thus beginning the assembly over the next year or so of their first space station, with ten more launches planned in that short time span.

The T-shape, 100-metric-ton CSS [Chinese Space Station] will comprise three major modules: the 18-meter-long core module, called Tianhe (“Harmony of the Heavens”), and two 14.4-meter-long experiment modules, called Wentian (“Quest for the Heavens”) and Mengtian (“Dreaming of the Heavens”), which will be permanently attached to either side of the core. As the station’s management and control center, Tianhe can accommodate three astronauts for stays of up to six months. Visiting astronauts and cargo spaceships will hook up to the core module from opposite ends. Both it and Wentian are equipped with robotic arms on the outside, and Mengtian has an airlock for the maintenance and repair of experiments mounted on the exterior of the station. Tianhe has a total of five docking ports, which means an extra module can be added for future expansion. The station is designed to operate for more than 10 years.

Much of the work on this station will be similar to the scientific research done on ISS. One additional science project linked to the station however is far more impressive:
