Has any one heard if the crew has dock with Tiangong 2 or if not does any one know when the docking will take place?RegardsThomas

I have never been known to speculate excessively (please stop laughing everyone) but ...........The Chinese have been talking about the Tiangong Complex as operating in a 400 km orbit. Having a play with some numbers suggests a 41.78 deg, 92.548 minutes orbital period with a mean altitude of 399 km gives a 107 circuits repeating orbit, that is every seven days less 177.4 minutes. This is a longer repeating pattern than we normally see with piloted missions.Of course, I could be taking the 400 km altitude too literally.

It was mentioned in the launch broadcast that the orbit is 393 km, the same as the future modular space station. N2YO gives an orbit of 381.1 x 392.8 km, but that is using the mean Earth Radius of 6371.009 km. Using the equatorial radius of 6378.137 km (like everyone else does I believe) gives an orbit of 374.0 x 385.7 km, which is a bit lower then 393 km.http://www.n2yo.com/satellite/?s=41765

The "Tiangong 2 subsatellite" (Tiangong er hao bansui weixing,天宫二号伴随卫星)was ejected from the TG-2/SZ-11 complex at 2331 UTC Oct 22
