Lowering InSight Cruise Stage onto Back Shell

Spacecraft specialists at Lockheed Martin Space Systems, Denver, are preparing to attach the cruise stage of NASA's InSight spacecraft to the top of the spacecraft's back shell in this April 29, 2015, photo. The cruise stage will serve multiple functions during the flight from Earth to Mars. It has its own solar arrays, thrusters and radio antennas. It will be jettisoned shortly before the spacecraft enters the Martian atmosphere. 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. Note: After thorough examination, NASA managers have decided to suspend the planned March 2016 launch of the Interior Exploration using Seismic Investigations Geodesy and Heat Transport (InSight) mission. The decision follows unsuccessful attempts to repair a leak in a section of the prime instrument in the science payload. http://photojournal.jpl.nasa.gov/catalog/PIA19667
