Johnson said outdated spacecraft, rocket stages and other components break apart in space every year, but there have only been three relatively minor collisions between such objects in the last 20 years. Never before have two intact satellites crashed into one another by accident, he added. The...
Exploding rockets -- This leaves behind the most debris in space. The slip of an astronaut's hand -- If an astronaut repairing something in space and drops a wrench, it's gone forever. The wrench then goes into orbit, probably at a speed of something like 6 miles per second (nearly 1...

"It is very rare to perform collision-avoidance manoeuvres with active satellites. The vast majority of ESA avoidance manoeuvres are the result of dead satellites or fragments from previous collisions. #SpaceDebris," they added in another tweet. You may like No satellite crash: 2 pieces of spac...
The starry sky visible to human eyes is quiet and peaceful, but in reality, there are many fierce celestial activities in the universe, such as explosions triggered by the death of supermassive stars, black holes tearing apart and devouring stars, and collisions between bizarre neutron stars and...
the population of cataloged objects around the Earth increased by more than 56% in just a couple of years, from January 2007 to February 2009, due to two collisions in space involving the catastrophic destruction of three intact satellites (Fengyun 1 C, Cosmos 2251 and Iridium 33) in high ...
MONTREAL, Oct. 27, 2020 /PRNewswire/ -- NorthStar Building World's First Satellite Constellation to Combat Imminent Threat of Space Collisions
Previous studies have concluded that fragments from random collisions in low Earth orbit will cause the orbital debris population to increase despite efforts to minimize the accumulation of debris. New data from the orbital history of fragments in space and the laboratory hypervelocity breakup of a pa...
, in order to be sure that the satellite did not impact the debris. A collision between pieces of debris or debris and an active satellite would create even more smaller debris, pieces which could be spread across an orbit, hence the concerns about the possibility ofsatellite collisions....
However, we may be entering an era of increasingly frequent space collisions — especially smashups like the Yunhai incident, in which a relatively small piece of debris wounds but doesn't kill a satellite. Humanity keeps launching more and more spacecraft, after all, at an ever-increasing pac...
