A spot of space debris illuminates in the night sky. Two problematic issues arise regarding derelict spacecraft: In orbit around the Earth, 'dead' and abandoned satellites threaten future travel in the same orbits with a spray of deadly debris. In orbit around extraterrestrial planets, non-sterile orbiters in decaying orbits threaten to pollute ...
Space debris includes a glove lost by astronaut Ed White on the first American space-walk (EVA), a camera lost by Michael Collins near Gemini 10, a thermal blanket lost during STS-88, garbage bags jettisoned by Soviet cosmonauts during Mir's 15-year life, [77] a wrench, and a toothbrush. [78] Sunita Williams of STS-116 lost a camera during an EVA.
It is estimated that there are 600,000 pieces of space junk ranging from 1 to 10 cm (1 ⁄ 2 to 4 in), and 23,000 larger than that. [24] On average, every year, one satellite is destroyed by collision with other satellites or space junk.
Nasa estimates there are more than 6,000 tonnes of space debris in orbit at the moment. There are many different estimates about the chances of such junk hitting someone, but most are in the one ...
There are approximately 45,000 objects in orbit, including some 18,800 pieces of space debris, being tracked by the U.S., according to Space-Track.org, the public website of the U.S. Space Command.
NASA said the debris was from SpaceX’s Crew-7 mission, which launched to space on Aug. 26, 2023, then returned after a six-month expedition at the space station.

The passivation of a spacecraft is the removal of any internal energy contained in the vehicle at the end of its mission or useful life. [1] Spent upper stages are generally passivated after their use as launch vehicles is complete, as are satellites when they can no longer be used for their design purpose.
