An inactive Russian satellite broke up into nearly 200 pieces, prompting astronauts on the space station to take shelter in a docked spacecraft and a capsule that could be used to escape in case of emergency.

Metal wreckage found in a Canadian farm turned out to be SpaceX spacecraft debris

The pieces of the wreck included a 36-kilogram aluminum spear more than 2 meters long, and its origins were confirmed by satellite tracker Jonathan McDowell. No government acknowledged or took accountability for the space trash, which SpaceX later quietly retrieved.

When retired, the International Space Station will undergo a controlled de-orbit

With plans to transition low-Earth orbit operations to private entities, the ISS is expected to be retired by 2030, using a SpaceX de-orbit vehicle. Although reentry will burn up most hardware, NASA intends for any surviving debris to fall into an uninhabited ocean area.

You are 65,000 times more likely to be struck by lightning than to be hit by space trash

In 2023, about 1,500 pieces of space junk fell to Earth, with most consisting of payload fragmentation debris. The vast majority that falls back to Earth burns up before reaching the surface, making it three times less likely to be struck by space trash than by a meteorite.

A financial analysis of space trash cleanup strategies identified long-term benefits

Despite significant initial costs, a NASA report found that removing small debris would provide savings from preventing mission-ending damage, which would offset expenses within a decade. Financial benefits would also come from using less fuel for maneuvers to avoid collisions with debris.

In 2018, SpaceX launched a Tesla Roadster into heliocentric orbit for publicity

As of February 2023, the vehicle and its mannequin driver—dubbed "Starman"—have completed three and a quarter revolutions around the sun. One paper estimated that the car has a 22% chance of crashing into Earth within the next 15 million years.
