Explore Mars wants to look for life on the Red Planet. Not past life. Life thriving under the Martian surface right now. Chris Carberry will tell us how the ExoLance project might find it. Emily Lakdawalla shows us the proposed landing sites on Rosetta’s comet. Bill Nye says NASA is about to choose the commercial contractor that will take astronauts to the International Space Station. Bruce Betts sends us searching for interplanetary leprechauns in the What’s Up space trivia contest.
