“NASA science activities have provided a wave of amazing findings related to water in recent years that inspire us to continue investigating our origins and the fascinating possibilities for other worlds, and life, in the universe,” Ellen Stofan, chief scientist for the agency, says in a feature on the abundance of water in the Universe.
“In our lifetime, we may very well finally answer whether we are alone in the solar system and beyond.”
