Download or read book Recent Direct Measurements by Satellites of Cosmic Dust in the Vicinity of the Earth written by H. E. LaGow and published by . This book was released on 1960 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2001-10-31 with total page 500 pages. Available in PDF, EPUB and Kindle. Book excerpt: Extraterrestrial matter affecting the earth varies in size from cosmic dust particles to the large meteor thought to have caused the mass extinction of the dinosaurs. In this volume, 22 contributions from Peucker-Ehrenbrink (Woods Hole Oceanographic Institution), Schmitz (U. of Goteborg, Sweden) and other international scientists discuss the accretion of extraterrestrial matter on Earth throughout the planet's history. Topics include, for example, the atmospheric entry heating of interplanetary dust, the sedimentary record of impact events, and the cosmic ray exposure history of meteorites. c. Book News Inc.
