STUDY ON THE EXTRATERRESTRIAL MATERIAL AT ANTARCTICA (I)
The study of the extraterrestrial material collected in Antarctica is reported. The extrateirestnal material comprises cosmic dust, tektite, and meteorite. Antarctica is the most suitable place for collecting such material, since the Antarctic Continent is covered with thick ice and is hardly contam...
