Launch Week Begins with Flight Readiness Review, Dress Rehearsal

Launch week is underway at Vandenberg Air Force Base in California, where NASA’s InSight spacecraft is being prepared for its upcoming flight to Mars. Mission and launch officials gathered Monday for the InSight flight readiness review. Teams are preparing to launch InSight on its United Launch Alliance Atlas V rocket Saturday, May 5, at 4:05 a.m. PDT (7:05 a.m. EDT).

Prelaunch activities continue today as launch team members take part in a countdown dress rehearsal.

InSight will be the first mission to look deep beneath the Martian surface. It will study the planet’s interior by measuring its heat output and listening for marsquakes. InSight will use the seismic waves generated by marsquakes to develop a map of the Red Planet’s deep interior. The resulting insight into Mars’ formation will provide a better understanding of how other rocky planets, including Earth, were created.

NASA’s Jet Propulsion Laboratory in Pasadena, California, manages the InSight mission for the agency’s Science Mission Directorate. InSight is part of NASA’s Discovery Program, managed by its Marshall Space Flight Center in Huntsville, Alabama. The spacecraft, including cruise stage and lander, was built and tested by Lockheed Martin Space in Denver. Several European partners, including France’s space agency, the Centre National d’Étude Spatiales, and the German Aerospace Center, are supporting the mission. United Launch Alliance of Centennial, Colorado, is providing the Atlas V launch service. NASA’s Launch Services Program, based at its Kennedy Space Center in Florida, is responsible for launch management.
