Julie Wertz-Chen, Entry, Descent and Landing systems engineer, NASA JPL, talks about Mars InSight from the Mission Control Area during a pre-landing briefing, Sunday, Nov. 25, 2018 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. InSight is scheduled to touch down on the Red Planet at approximately noon PST (3 p.m. EST) on Nov. 26. Photo Credit: (NASA/Bill Ingalls)
