Living on Mars is a far-off dream, for now. But what would it take to do it? And what might life be like there for humans? The Associated Press asked fifth-graders from Stacie Kaeuper’s class at Wyatt Elementary School in Plano, Texas, to pose questions about traveling to the so-called red planet and the possibility of people living there. The answers were provided by Deborah Bass and Bob Mase, both scientists at NASA’s Jet Propulsion Lab in Pasadena, Calif. Bass is an engineer and deputy science team chief who helps ensure that rovers sent to the surface of Mars send back as much scientific data as possible. Mase is manager of the 2001 Mars Odyssey mission.
