 On 26 June 2013, after a series of successful docking tests, Shenzhou 10 returned to Earth.Prior to the reboost of Tiangong 1 on 30 August 2012, it was projected that a launch window would open between late November and December 2012, when Tiangong-1's orbit had decayed to the level of a Shenzhou's standard orbit.With the reboost, it was expected that the orbital decay would bring Tiangong-1 within reach again in late January, so the Shenzhou 10 mission was anticipated for late January or February 2013.
