Mission Name: HEOS 2This experiment was designed to measure the flux, mass, and velocity of micrometeoroids as a function of earth distance. The instrumentation consisted of an ion collector centered in a hemispherical container that was located in the octagonal-tube center structure of the spacecraft. Dust particles impacting on the hemisphere created secondary ions on the collector. Combinations of grids having voltages between -100 v and +300 v were located in front of the detector to counteract any effects due to solar wind charged particles. Data were obtained from both the interplanetary region and the high-latitude portion of the magnetosphere (400 to 245,000 km). The experiment was designed to operate for at least 1 yr.
