Photos: Atlas 5 rolls out for launch

Lending a helping hand to resume the stalled U.S. supply chain to the International Space Station, a United Launch Alliance Atlas 5 rocket will send a commercial Cygnus cargo craft in pursuit of the outpost Thursday.

When Chris Ferguson climbed into the commander’s seat of the shuttle Atlantis five years ago for the spaceship’s final flight, he didn’t know what turn his career would take when he returned to Earth. Now the former F-14 fighter pilot helps lead Boeing’s development of the CST-100 Starliner space taxi, one of two U.S.-built commercial spacecraft selected by NASA to ferry astronauts to and from the International Space Station.

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.
