100mn+ millimeter-sized space debris a serious threat to astronauts, says NASA Chief Scientist
The word space debris can commonly be interpreted as man-made objects in space that are no longer serving a useful purpose. This could include large and small defunct satellites, spent upper stages of rockets, etc. However, the larger objects are far lesser in number, and it is far easier to track and predict their movement, whereas the real threat to space assets is posed by millions of millimetre-sized space debris, said a top NASA scientist.
