This artist's concept shows the InSight lander, its sensors, cameras and instruments. InSight is will take the first-ever-in-depth look at Mars' "inner space." InSight stands for Interior Exploration using Seismic Investigations, Geodesy and Heat Transport. Its three instruments are a seismometer, a heat flow probe, and a radio science experiment. These instruments will shed light on how warm and geologically active Mars still is, study its reflexes as it whips about in its orbit around the sun, and provide essential clues on the evolution of the rocky planets of our solar system. So while InSight is a Mars mission, it's also more than a Mars mission. InSight will launch between May 5 through June 8, 2018 from Vandenberg Air Force Base in California. https://photojournal.jpl.nasa.gov/catalog/PIA22227
