Photos: Falcon takes flight

SpaceX is targeting Saturday for launch of its next space station resupply mission from Cape Canaveral after a problem with an upper stage steering system actuator flared up during a countdown Tuesday.

The proposal would allow SpaceX to take over Space Launch Complex 6, United Launch Alliance’s former Delta 4 launch site, and convert it for use to launch both Falcon 9 and Falcon Heavy rockets.

NASA has agreed to consider a Boeing proposal to extend the first piloted test flight of its commercial CST-100 Starliner crew capsule from two weeks to up to six months with an extra crew member for the International Space Station, hedging against potential delays that could jeopardize U.S. crew access to the orbiting outpost.
