Tiny bits of space junk too small to track using current methods could be detected by a novel process using by ground-based radio dishes, according to the latest research.
Big pieces of space junk, like parts of spent rocket boosters or broken satellites, are easy to spot because their orbits are known and they’re big enough to get a reading on. But the millions of smaller items are harder to find, and more are appearing as large items of orbital debris slowly degrade and fragment.
