Video: Time lapse of ATV’s final departure from ISS

A Northrop Grumman Antares rocket rolled out of its hangar Monday night, riding a self-propelled transporter for a mile-long trip to launch pad 0A on Wallops Island, Virginia, for a predawn liftoff Thursday with a Cygnus supply ship heading for the International Space Station.

NASA and SpaceX officials are moving forward with preparations to launch the next commercial Crew Dragon mission to the International Space Station next week after a Flight Readiness Review Thursday, pending a final evaluation of a discovery by SpaceX that it has potentially been loading slightly more propellant than expected into its Falcon 9 rockets.

A SpaceX Falcon 9 rocket lifted off from Space Launch Complex 4-East at Vandenberg Air Force Base in California at 12:17 p.m. EST (9:17 a.m. PST; 1717 GMT) Saturday with an oceanography satellite jointly developed by U.S. and European space and weather agencies. The rocket’s first stage booster returned to a bullseye landing back at Vandenberg.
