NASA InSight Mission | What's Inside Mars?

March 19, 2018 • 1:07

InSight is a Mars lander designed to give the Red Planet its first thorough checkup since it formed 4.5 billion years ago, and the first outer space robotic explorer to study in depth the "inner space" of Mars: its crust, mantle, and core. Studying the interior structure of Mars answers key questions about the early formation of rocky planets in our inner solar system more than 4 billion years ago. The lander uses cutting-edge instruments to delve deep beneath the surface and seek the fingerprints of the processes that formed the terrestrial planets. This mission is part of NASA's Discovery Program for highly focused science missions that ask critical questions in solar system science. NASA's InSight Roadshow visited the Exploratorium April 18–22, 2018.
