InSight Probes the 'Inner Space' of Mars

InSight, short for Interior Exploration using Seismic Investigations, Geodesy and Heat Transport, is designed to give the Red Planet its first thorough check up since it formed 4.5 billion years ago. It is scheduled to launch from Vandenberg Air Force Base on the California coast between May 5 through June 8, 2018, and land on Mars six months later.

InSight will look for tectonic activity and meteorite impacts, study how much heat is still flowing through the planet, and track Mars' wobble as it orbits the sun. While InSight is a Mars mission, it's more than a Mars mission. InSight will help answer key questions about the formation of the rocky planets of the solar system.
