Tom Hoffman, InSight Project Manager, NASA JPL, left, and Bruce Banerdt, InSight Principal Investigator, NASA JPL, laugh together after reviewing the first image of Mars taken by the Mars InSight lander, Monday, Nov. 26, 2018 inside the Mission Support Area at NASA's Jet Propulsion Laboratory in Pasadena, California. InSight, short for Interior Exploration using Seismic Investigations, Geodesy and Heat Transport, is a Mars lander designed to study the "inner space" of Mars: its crust, mantle, and core.
