Jupiter Moon May Have Life – Experts Urge a Mission

Scientists say Jupiter’s moon Europa rivals Mars as a potential refuge for life. Some of them are now urging NASA to explore the ice-covered satellite.

“It takes longer to get there [than to get to Mars], it’s more expensive, and a bigger deal to plan a mission. But if I had a choice, I’d go for Europa,” said Lynn Rothschild, an astrobiologist with the NASA Ames Research Center in Moffett Field, California.
