Photos: Atlas 5 rolls out for launch

Ground crews at Vandenberg Air Force Base on California’s Central Coast hoisted NASA’s InSight Mars lander atop a United Launch Alliance Atlas 5 rocket Monday, kicking off nearly two weeks of integrated tests and checkouts before the probe’s interplanetary launch window opens May 5.

Boeing’s Starliner crew capsule accomplished an early at White Sands Space Harbor in New Mexico at 7:58 a.m. EST (5:58 a.m. MST; 1258 GMT) Sunday to conclude an abbreviated two-day unpiloted test flight after a timing error on the spacecraft shortly after launch prevented it from linking up with the International Space Station as planned.

Loaded with investigations into chemotherapy drugs with reduced side effects and radiation detectors for homeland security, a plant-growing chamber to promote future food harvesting in space and a technology demonstration for sample-return capsules, a commercial Cygnus cargo vessel will be sent to the International Space Station next week.
