Atlas 5 launches NROL-61 as seen from the NASA Press Site

NASA’s InSight Mars lander will be buttoned up for launch in the coming weeks at Vandenberg Air Force Base in California, in preparation for its hoisting atop an Atlas 5 rocket for blastoff in the predawn hours of May 5.

United Launch Alliance’s Atlas 5 rocket, modified for crewed launches, rolled out of the Vertical Integration Facility Wednesday for the 1,800-foot trek to pad 41 in preparation for liftoff with Boeing’s Starliner crew capsule on an unpiloted mission to the International Space Station.

The United Launch Alliance Atlas 5 rocket, equipped with three strap-on solid-propellant boosters for added performance, was transfered from its assembly building to the pad at Cape Canaveral’s Complex 41 today for Sunday’s launch of the commercial EchoStar 19 communications satellite.
