PASADENA, Calif., Sept. 4 (UPI) -- NASA says it's chosen four possible possible landing sites for a 2016 Mars mission, all located close together in the Red Planet's Elysium Planitia area.
The InSight mission will settle a lander on the surface to study Mars' interior, rather than surface features, to advance understanding of the processes that formed and shaped the rocky planets of the inner solar system, including Earth, NASA's Jet Propulsion Laboratory in Pasadena, Calif., reported Wednesday.
