NASA's Mars Interior Exploration using Seismic Investigations, Geodesy and Heat Transport (InSight) mission is on a 300-million-mile (483-million-kilometer) trip to Mars to study for the first time what lies deep beneath the surface of the Red Planet. InSight is scheduled to land on the Red Planet around 3 p.m. EST (noon PST) Nov. 26, where it will conduct science operations until Nov. 24, 2020, which equates to one year and 40 days on Mars, or nearly two Earth years.
