A confirmation has arrived that three Chinese taikonauts from the Shenzhou 21 mission reached the Chinese space station Tiangong with an automated docking maneuver. They blasted off about 3.5 hours earlier atop a Long March-2F rocket from the Jiuquan Satellite Launch Center. They form the 10th crew of the Chinese space station and will remain there for about six months, the standard duration for a mission.
