Artist's Concept of InSight Lander on Mars: InSight was the first mission dedicated to investigating the deep interior of Mars. The findings advance understanding of how all rocky planets, including Earth, formed and evolved.

    What Were InSight's Science Tools?

    The InSight Lander’s three primary instruments, SEIS, HP3, and RISE, were designed to take the first-ever in-depth look at the planet's “inner space.” The mission’s goal was to study the fingerprints of the process of planet formation, buried deep in the Martian interior. InSight’s science measurements potentially can shed light on just how warm and geologically active Mars still is, and provide essential clues on the evolution of Mars and of all the terrestrial planets.
