Poor Man’s Space Probe in Laboratory!
Kuljeet Marhas, Physical Research Laboratory
Origin and early evolution of the solar system has remained one of the most intriguing questions for a long time. Numerous experimental and theoretical approaches have been employed to seek an unequivocal answer to this question. The progress in experimental techniques and computing capabilities in the last few decades has led to significant advances in this area of research. Owing to unique chemistry and nearly pristine nature, meteorites constitute the most important accessible component of solar system material that may be analyzed to unfold the story of the origin and early evolution of the solar system.
Origin of water and life have been one of the most enigmatic topic in recent times that has also attracted significant interest from meteoriticists. Laboratory analyses of various anhydrous and hydrated phases in meteorites (from the asteroidal region, the Mars, and the Moon) and the comet samples from sample-return missions have greatly contributed towards determining, rather precisely, abundances of volatiles including water in the Solar System. In my talk, I will compare the isotopic data of volatiles and organics from primitive early solar system objects and discuss their importance in understanding the possibility of life.
