Closing in on the origin of terrestrial water: Philae calls back home

by Tansu Daylan figures by Kaitlyn Choi As Philae just woke up, we examine one exciting question of the Rosetta mission: what is the origin of water on Earth? A hypothesis proposes that comets brought to our planet this molecule central to life. The Rosetta mission is an ambitious scientific program launched by the European Space Agency to analyze the water on the comet 67P … Continue reading Closing in on the origin of terrestrial water: Philae calls back home
