InSight, short for Interior Exploration using Seismic Investigations, Geodesy and Heat Transport, is a robotic lander designed to study the deep interior of the planet Mars.

InSight launched on May 5, 2018 and successfully landed on Mars on Nov. 26, 2018. Its finding are expected to shed light on the processes responsible for the formation of Mars, Earth, and even rocky exoplanets more than 4 billion years ago.
