The Shenzhou-20 crew returned to Earth on Friday – and their journey has become a powerful symbol of resilience for China's space program. When space debris forced a change of plans, tens of thousands of people across departments came together to bring them safely back aboard the Shenzhou-21 spacecraft. The taikonauts' courage in overcoming countless difficulties in space, combined with their strong qualities, has inspired people in the space industry. As one team member put it: "Unity is strength" – and this mission proved it.
