Can we stop space from filling up with junk?
Update: 2025-11-17
Description
Space is big... but not infinite. The area around the Earth is populated by thousands of satellites and a million pieces of space debris, and those objects could stay in orbit for decades. Adding to the complexity, since 2019 there's been a growth-spurt in the number of satellites being sent into space. Is it possible to avoid a catastrophic build-up of junk in orbit that could make space unusable?
