National Geographic Live! The Search for Life Beyond Earth with Planetary Scientist/Astrobiologist Kevin Hand
When NASA’s Galileo mission detected hints of a vast sub-surface ocean on Europa (Jupiter’s fourth largest moon), intense curiosity was sparked about the potential for finding life in this alien world. Kevin Hand is helping plan a NASA mission to Europa to get a closer look. He has traveled to the most forbidding environments on Earth, exploring the north slope of Alaska, the glaciers of Mount Kilimanjaro, the valleys of Antarctica and the depths of our oceans to see how microbes eke out a living in our world’s harshest climates.
