how fast is the space debris traveling
Instead, a piece of space debris moving at more than 20,000 miles per hour nearly wiped out the station and its six-member crew. Tuesday marked the second time that crew members took refuge in Soyuz âlifeboatâ capsules. There was a near miss with a satellite motor in 2009.here are more than 20,000 pieces of space junk that measure larger than a softball, and these are tracked by the Department of Defense. Together, both NASA and DoD use ground-based sensors to survey each objectâs orbit. However, there are many millions of smaller discards that cannot be tracked.
