The Shenzhou XVII manned spacecraft is targeted for launch at 10:26 on October 11. The main purpose of the mission is to complete the on-orbit rotation with the Shenzhou 6 crew. The Shenzhou 17 mission will carry out extravehicular experimental maintenance operations on the space station for the first time. The mission is the 30th flight mission and the 12th manned mission since the implementation of the manned space project. It is inevitable that long-term spacecraft will be hit by space particles.
