Principal Investigator National Institute of Oceanography ,Goa M. Shyam Prasad: [email protected]
Main Activity/ Remarks The aim of the project is to investigate, identify and characterize the cosmic dust that would be collected from the icy continent of Antarctica and estimate the flux of micrometeorites on earth. Identify the various phases of minerals, textures and elements present in the micrometeorites. This would help us understand the earth crossing meteoroid complex. Since the contribution to the dust is expected from both cometary and asteroidal materials, we would have a window to understand that various mineralogical and chemical phases that comprise the cometary and asteroidal materials and these investigations would add effectively to the inventory of solar system materials. Cosmic dust offers us a wider range of asteroidal/cometary materials as compared with the conventional meteorites, therefore the study of such a large concentration of micrometeorites would help understand extraterrestrial material more comprehensively. Their oxygen isotopic compositions in conjunction with their major, minor and trace element compositions would help in understand mass fractionation of the materials, determine their thermal histories and more importantly provide a window to understand primitive, early solar system processes. Aqueous alteration of cosmic dust offers
possibilities of understanding the origin of water in the solar system.
