Space Junk: a Growing Threat to Satellites and Spacecraft

The video discusses the issue of space debris, which includes not only satellites but also other objects like fairings and boosters. These objects can explode and create debris, posing a threat to operational spacecraft. The European Space Agency tracks thousands of pieces of space junk to prevent collisions. The video highlights the challenges of managing space debris, especially as the number of objects in orbit increases. It also mentions historical context, such as the launch of Vanguard One, which remains in orbit as the oldest piece of space junk.

What happens to boosters that still contain fuel after prolonged exposure to the sun?

• They return to Earth.

• They explode, creating debris.

• They become satellites.

• They become more efficient.
