A chunk of space debris, too small to track and dodge in time, struck the International Space Station (ISS). Damaged the Canadarm2 robot arm. The device works, but debris has penetrated the heat shield and destroyed the boom. The incident is a sobering reminder that the space debris problem is a ticking time bomb. Space agencies around the world are aware of the threats, so they track over 23,000 people. items. Unfortunately, as it turns out, it is impossible to track them all. This is especially true for items that are smaller than a tennis ball. Even such a small amount of rubbish can cause serious damage to the station. For example, break through metal plates. It is not clear when the Canadarm2 failed. They were spotted on May 12 during a routine inspection.
