Part 3/9:
The incident underscores the persistent danger of space debris, which continually threatens operational satellites and manned stations. The problem is worsened by imperfect tracking systems, meaning there are times when debris is projected to pass close but avoidance is not always feasible. Luckily, in the recent incident, no one was harmed, and the Chinese station was able to send up a replacement craft and safely bring astronauts home.
