Starting next year, scientists will get their first look deep below the surface of Mars.

That's when NASA will send the first robotic lander dedicated to exploring the planet's subsurface. InSight, which stands for Interior Exploration using Seismic Investigations, will study marsquakes to learn about the Martian crust, mantle and core.

Doing so could help answer a big question: how are planets born?

Seismology, the study of quakes, has already revealed some of the answers here on Earth, said Bruce Banerdt, Insight's principal investigator at NASA's Jet Propulsion Laboratory, Pasadena, California. But Earth has been churning its geologic record for billions of years, hiding its most ancient history. Mars, at half the size of Earth, churns far less: it's a fossil planet, preserving the history of its early birth.

We know what "The Red Planet" looks like from the outside -- but what's going on under the surface of Mars? Find out more in the 60-second video from NASA's Jet Propulsion Laboratory.

NASA's next mission to Mars is weeks away from its May 2018 launch. InSight is more than a Mars mission. Its team members hope to unlock the mysteries of the formation and evolution of rocky planets, including Earth.
