Book Description
Direct measurements of the space density of cosmic dust particles in the vicinity of the earth have been made from rockets, satellites, and space probes. The largest data samples have been obtained from crystal transducer sensors that detect the impact-impulses occurring from the collision of dust particles on sensitive surfaces of space vehicles. Preliminary results from satellite 1959 ETA show: (1) over 1500 impacts and an area-time product greater than 10(exp 1O) sq cm-sec; and (2) a daily variation in the dust particle density near the earth. The dust particle instrumentation of 1959 ETA and sensor calibration techniques are discussed in this paper. The results of direct measurements from space vehicles prior to 1959 ETA are summarized with respect to 1959 ETA information.
