There’s an uptick in reports of people finding downed space junk on Earth. Over the years, some recovered wreckage from incoming rocket bodies and spacecraft has been trucked into research facilities for intensive scrutiny.

Up close inspection of the scraps from afar is aiding research into the fiery and destructive reentry process.

One research avenue is to establish design alternatives that would cause incoming space hardware to “disintegrate” during their plummet through Earth’s atmosphere – called “design for demise” in space rubbish vernacular.

Chunks of space junk rained down in Australia, later identified as SpaceX leftovers from its Crew-1 Mission that flew in 2020-2021.
