Hurray! These two space debris crafts missed each other last night, Thursday, October 15
Some blurbs from the report I read say:
"Bullet dodged," McDowell said on Twitter. "But space debris is still a big problem."
Space collisions make clouds of dangerous high-speed debris
Nearly 130 million bits of space junk currently surround Earth, from abandoned satellites, spacecraft that broke apart, and other missions. That debris travels at roughly 10 times the speed of a bullet, which is fast enough to inflict disastrous damage to vital equipment, no matter how small the pieces.
A debris disaster could cut off our access to space
If the space-junk problem were to get extreme, a chain of collisions could spiral out of control and surround Earth in an impassable field of debris. This possibility is known as a Kessler event, after Donald J. Kessler, who worked for NASA's Johnson Space Center and calculated in a 1978 paper that it could take hundreds of years for such debris to clear up enough to make spaceflight safe again.
