Was Mars once covered in oceans? If so, where did they go? Like many scientific endeavors, understanding the history of water on Mars is a team effort, and Gina DiBraccio and Charles Malespin from NASA’s Goddard Space Flight Center’s research on the topic frequently requires many perspectives and points of view. In this lecture they will join together to talk about water on Mars from top to bottom. DiBraccio will highlight how Mars' ocean escaped into space through the atmosphere, and Malespin will tell us all about how Mars' rovers have deepened our understanding of the fate of oceans on Mars from the ground.

Gina DiBraccio is the deputy director of the Heliophysics Science Division at NASA's Goddard Space Flight Center. Her research focuses on magnetospheric physics and solar wind-planetary interactions for both intrinsic and induced planetary magnetospheres throughout the Solar System. Charles Malespin is the chief of the Planetary Environments Lab, and serves as the principal investigator for the Sample Analysis at Mars (SAM) instrument suite currently on the Curiosity rover in Gale Crater, Mars.
