Europa Clipper is a NASA mission to explore Jupiter's moon Europa, which is believed to have a subsurface ocean of liquid water that could potentially harbor life. The spacecraft will conduct multiple flybys of Europa to study its surface and atmosphere, as well as gather data on the thickness of the moon's icy crust and the composition of its subsurface ocean. The mission aims to help scientists better understand the potential habitability of Europa and the possibility of finding life beyond Earth. Europa Clipper is scheduled to launch in the early 2020s.
