Chinese ASAT -- free-flier 'inspectors'??
Notice, in regard to the old 'parasite satellite' controversy (the fact that a private Chinese website talked about the concept is NOT proof that the Chinese military is NOT interested in it), that apparently the Chinese do have a minisatellite that can 'formation fly' with a larger satellite -- and that they consider it safe and reliable enough to do so with a human spacecraft while a crewman is performing a spacewalk. That suggests to me that the operation just announced with the Shenzhou next year will NOT be the first time such hardware (and control software) has been tested on a Chinese space mission. China's Manned Spacecraft To Carry Small Satellite Beijing, China (XNA) Jan 22, 2007 When Chinese astronauts eventually walk in space, a small satellite will be used to monitor their movements, said a satellite expert on Thursday. The satellite will be launched from the manned spacecraft and orbit around it. It will keep a close watch on spacecraft conditions and help monitor the astronauts' spacewalks, China News Service reported. The next step in China's manned spaceflight program -- which could happen as early as 2008 -- involves allowing the astronauts to walk out of the spacecraft and dock the spacecraft with another target object, according to Sun Laiyan, head of China's National Space Administration. Yang Genqing, a researcher with the Shanghai-based Small and Micro Satellite Research Institute, said small satellites weigh between 100 and 1,000 kilograms. Compared with traditional satellites, small satellites are cheaper and quicker to manufacture, consume less energy consumption and are more reliable, Yang said. Small satellites can link to form a "constellation" and outperform traditional satellites, according to Yang. Xinhua News Agency |

If it goes up attached to the Shenzhou and is then seperated, and only has wimpy cold gas thrusters, would it really be that dangerous? Couldn't is just be a bigger version of that basketball like thing they were talking about playing with inside ISS or shuttle? Now if it's something like a progress that does a remote control or automated rendezvous after seperate launch, yeah, you'd want to test that on an unmanned target... |
