InSight Mission | Why Mars?

March 19, 2018 • 1:00

On a mission launched in May 2018, the Mars lander InSight will give the Red Planet its first thorough checkup since it formed 4.5 billion years ago, the first outer-space robotic explorer to study in depth the "inner space" of Mars: its crust, mantle, and core. Studying the interior of Mars answers key questions about the early formation of rocky planets in our inner solar system—Mercury, Venus, Earth, and Mars. This mission is part of NASA's Discovery Program for highly focused science missions that ask critical questions in solar system science. The InSight Roadshow visited the Exploratorium April 18–22, 2018.
