神舟十二号飞往空间站6.5个小时，返回地球为何却要28.5个小时3

The return journey of Shenzhou XII to Earth from the space station took longer than initially planned due to minor trajectory deviation during the mission, necessitating orbit adjustments, safety considerations for desert landing, and ensuring optimal conditions for search and rescue. The spacecraft remained in orbit until the next day to complete its maneuvers.
