A NASA Langley Research Center meteoroid detection experiment will be performed on both the Pioneer F and G missions. The objective of this experiment is to obtain data that will indicate the population of meteoroids in the 10-9 to 10-8 g mass range in interplanetary space and, in particular, the region of the asteroid belt, and establish a first indication of the meteoroid penetration hazard to spacecraft in the asteroid belt. Specifically, the experiment will detect meteoroid penetrations of stainless steel targets 25 and 50 µm (1 and 2 mils) thick as the Pioneer spacecraft travel in interplanetary space through the asteroid belt to Jupiter and beyond.
