In this photo, a spacecraft specialist prepares NASA's InSight spacecraft for thermal vacuum testing in the flight system's "cruise" configuration for its 2016 flight to Mars. The testing simulates conditions of outer space that InSight will experience during its flight. The photo was taken on May 29, 2015, in a clean room of spacecraft assembly and test facilities at Lockheed Martin Space Systems, Denver.
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.
