Photos: Delta 4 powers from launch pad on military mission

China’s Haiyang 2B oceanography satellite, the follow-on to a space mission launched seven years ago, lifted off Wednesday from the country’s Taiyuan launch base aboard a Long March 4B booster.

Engineers from Boeing and a team of subcontractors have finished building the first pair of six new solar arrays to bolster the International Space Station’s aging electrical system ahead of their launch to the orbiting outpost as soon as May aboard SpaceX’s next Cargo Dragon mission.

SpaceX scrubbed the launch of its next Starship test rocket Friday afternoon, and the the next opportunity for the atmospheric test flight is now expected Tuesday. SpaceX plans to launch and land the rocket at company’s South Texas development complex after losing three previous prototypes in explosions.
