InSight's Launch

InSight launched under pre-dawn skies from Vandenberg Air Force Base on the central coast of California on May 5, 2018 at 4:05 a.m. PDT (7:05 a.m. EDT).

InSight launched from Launch Complex 3 on an Atlas V-401 rocket provided by United Launch Alliance, Centennial Colorado, a joint venture of Boeing Co. and Lockheed Martin Corp.

The Atlas V is one of the biggest rockets available for interplanetary flight. This is the same type of rocket that launched the Mars Reconnaissance Orbiter in 2005.

InSight is the first mission to another planet to leave Earth from Vandenberg Air Force Base. Missions to other planets normally launch from NASA's Kennedy Space Center and fly east, over water. That's because launching towards the east adds the momentum of Earth's eastward rotation to the launch vehicle's own thrust. But the Atlas V-401 is powerful enough to fly south towards the sea from Vandenberg Air Force Base. Besides, Vandenberg Air Force Base was more available at this time to accommodate InSight's five-week launch period.

The launch is only the beginning; the trip to Mars takes about six months. The journey is about 301 million miles (485 million kilometers). InSight lands on Mars on Nov. 26, 2018.
