Space around Earth is filling up with junk: dead satellites, spent rocket stages, and fragments from past collisions, all traveling fast enough to shred anything in their path. This DW film tracks the growing risk that comes with cheaper launches and crowded orbits, including moments when the International Space Station has to dodge debris entirely. German astronaut Matthias Maurer describes what happens during a collision alert, when the crew seals every hatch and retreats to the docked capsule that serves as a lifeboat, then waits. The film then turns to the cleanup side of the problem, visiting the Munich-based company HPS, which has built a drag sail meant to pull dead satellites out of orbit faster so they burn up in the atmosphere instead of lingering for decades. Early in-orbit tests of the sail are shown alongside interviews with engineers explaining how the technology works and why the debris problem is only getting worse as more companies launch mega-constellations. It is a tidy, specific look at a crowded sky most people never think about.
