China abandons Shenzhou-20 in orbit as crew returns after damage
Three Chinese astronauts, stranded on Tiangong for over a week, returned on Shenzhou-21 after space debris damaged their Shenzhou-20 spacecraft. The China Manned Space Agency abandoned Shenzhou-20 in orbit, keeping it docked at the station. It now needs to be repaired in orbit before being returned or completely removed, as Tiangong's docking port must be kept free for other missions.
