NEEMO is a long-running NASA project that is helping to prepare us for mission to Mars and other destinations. Mat Kaplan talked with engineer and NEEMO Expedition 20 team member David Coan while he was hard at work with astronauts and other engineers living in the Aquarius undersea habitat. One lucky library is getting its space book collection reviewed by none other than Emily Lakdawalla. Director of Advocacy Casey Dreier provides an inside the beltway update, and Bruce Betts has his own undersea encounter.
