Once NASA's InSight Mars lander enters the Martian atmosphere and approaches the planet's surface, propulsive landing gear will slow the spacecraft down to about 5.5 mph (8.8 km/h) and safely set it down on the surface of the Red Planet. This image, taken at Lockheed Martin Space in Littleton, Colorado, shows several of the critical landing systems including the thrusters, lander legs and science deck.

JPL, a division of Caltech in Pasadena, California, manages InSight for NASA's Science Mission Directorate in Washington. InSight is part of NASA's Discovery Program, managed by the agency's Marshall Space Flight Center in Huntsville, Alabama. The InSight spacecraft was built and tested by Lockheed Martin Space in Denver, Colorado.
