Snapshots from Atlas 5 launch

The United Launch Alliance Atlas 5 rocket carrying NASA’s InSight lander toward Mars will have a roughly two-hour predawn launch window each day from May 5 through June 8 to boost the science probe into space from Vandenberg Air Force Base, California.

Mission leaders Tuesday gave approval for rollout of the United Launch Alliance Atlas 5 rocket to its pad on Wednesday morning, leading to liftoff Thursday evening of a NASA probe to rendezvous with an asteroid and bring a sample back to Earth.

Despite NASA’s concerns about earlier thruster problems and multiple helium leaks in the ship’s propulsion pressurization system, the Starliner had no trouble undocking and moving away from the station at 6:04 p.m. EDT and executing a critical 59-second deorbit braking maneuver at 11:17 p.m. to drop out of orbit.
