Robot Submarine on Jupiter Moon Europa is ‘Holy Grail’ Mission for Planetary Science

Sending a submarine to the bottom of the ocean on Jupiter’s icy moon Europa is the most exciting potential mission in planetary science, according to one prominent researcher.

Europa’s seafloor may well be capable of supporting life as we know it today, said Cornell University’s Steve Squyres, lead scientist for NASA’s Opportunity Mars rover, which is currently roaming the Red Planet. So a Europa robotic submarine mission is at the top of his wish list, though it likely won’t happen anytime soon.

“This is fantastic stuff,” Squyres said Wednesday (March 21) at a conference called Nuclear and Emerging Technologies for Space in The Woodlands, Texas. “This is the holy grail of planetary exploration right here.”
