ULA launches Mars InSight

United Launch Alliance (ULA) successfully launched NASA’s Mars InSight lander today aboard their Atlas V rocket in the 401 configuration from Space Launch Complex-3 at Vandenberg Air Force Base.

Following a smooth countdown, the rocket lifted off at 7:05 AM EDT and approximately 94 minutes later the spacecraft separated from the upper stage to begin its six-month journey to the red planet.

After separation of the main payload, two CubeSats MarCO-A and MarCO-B were also successfully deployed and will accompany InSight on its journey.  They will be used to relay information from InSight during it’s landing on Mars in November.

This was the first time that a spacecraft destined for another planet had been launched from the west coast.
