Spacecraft Unveiled

The Interior Exploration using Seismic Investigations, Geodesy and Heat Transport, also known as InSight, rests securely atop the Atlas-V rocket at SLC-3 as the mobile service tower rolls away. The craft will launch in the near future to begin its mission to study the crust, mantle and core of Mars.

A Bit of History

Lori Glaze, NASA Headquarters acting director of the Planetary Science Division, discusses missions to Mars over the years. The Mars InSight lander will study the deep interior of the Red Planet using a seismometer and a probe to monitor heat flow in the subsurface, among other instruments.
