Photos: Delta 4’s foggy launch

Originally expected to take off Saturday, the launch of SpaceX’s first operational Crew Dragon mission was delayed to Sunday because of expected high winds at the Kennedy Space Center and weather off-shore where the Falcon 9 rocket’s first stage will attempt to land on a SpaceX droneship. The company plans to re-use the booster for the next Crew Dragon flight.

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.

Five European satellites, including a Italian radar surveillance craft and an ESA exoplanet probe, lifted off Wednesday at 0854 GMT (3:54 a.m. EST) from French Guiana aboard a Russian Soyuz rocket. A launch attempt Tuesday was scrubbed due to a software concern with the launch vehicle.
