Description:
In the past, flight experiments to define the meteoroid environment near the Earth and in interplanetary space were undertaken. The effectiveness of meteoroid bumpers was investigated. These flight experiments were aboard Pioneer 10, Pioneer 11, and Explorer 46. Hypervelocity impact tests were conducted in the laboratory to study protective structures and the composition of meteoroids from the hundreds of meteor spectra obtained. It was also found that manmade debris presented a similar hazard to spacecraft near the Earth. An assessment of that hazard is made in this paper. An analysis of the collision probability problem with much attention given to the population of small untrackable fragments created during explosions is presented.
