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. At the
18th National Congress of the Chinese Communist Party, a space official stated that Shenzhou 10 was planned for the period between June and August 2013. It is the fifth crewed mission of the Shenzhou program, coming ten years after the original,
Shenzhou 5. From 2012 November onwards, a feed of information ensued, including a desire for the crew to have a female member and that the actual launch date would be at the beginning of the June–August period. Knowledge of the conditions that China sets for launch windows for its piloted spacecraft allowed the likely launch date to be calculated as somewhere in the period between 7 and 13 June.
Xinhua News Agency published an item from the
Beijing Times that summed up the aims of the mission, and included the information that
Wang Yaping was the only female trainee in the group of astronaut candidates. Wang Yaping was announced to be one of the crew in April 2013, the only member of the crew revealed until June, when the rest of the crew was revealed. The crew of Shenzhou 10 previously served as the backup crew to
Shenzhou 9. With
Nie Haisheng's elevation to general, this marked the first instance that China would launch a
flag officer into space, after they had become a general officer. ==Launch and docking==
