Spacecraft specialists at Lockheed Martin Space Systems, Denver, prepare NASA's InSight spacecraft for vibration testing as part of assuring that it is ready for the rigors of launch from Earth and flight to Mars. The spacecraft is oriented with its heat shield facing up in this July 13, 2015, photograph.

InSight, for Interior Exploration Using Seismic Investigations, Geodesy and Heat Transport, is scheduled for launch in March 2016 and landing in September 2016. It will study the deep interior of Mars to advance understanding of the early history of all rocky planets, including Earth.

The InSight Project is managed by NASA's Jet Propulsion Laboratory, Pasadena, California, for the NASA Science Mission Directorate, Washington. Lockheed Martin is building and testing the spacecraft. InSight is part of NASA's Discovery Program, which is managed by NASA's Marshall Space Flight Center in Huntsville, Alabama.
