・主な業績
Prof. Sushil Atreya has been studying the origin and evolution of the atmospheres of planets and satellites, climate systems, as well as habitability in our solar system and in extrasolar systems. Recently, he played a major role in defining and fine-tuning key science drivers of the SAM (Sample Analysis at Mars) instrument suite on board the Curiosity rover that landed in Gale Crater of Mars in 2012. SAM confirmed unambiguously the existence of methane and recorded its local, short-time scale variations as well as seasonal change that could not be explained either by clathrate release, surface adsorption with subsequent release or seasonal change in known atmospheric parameters, thus changing our view of the red planet to a more complex and dynamic body that is currently active.
