SpaceX will go for another first Thursday, this time flying a refurbished Dragon supply ship carrying nearly 6,000 pounds of cargo and experiments to the International Space Station nearly three years after its first mission.

Northrop Grumman’s Antares rocket will deliver a Cygnus supply ship into orbit Saturday to begin a pursuit of the International Space Station.

SpaceX teams at Cape Canaveral raised a Falcon 9 rocket vertical at the Complex 40 launch pad and performed a static fire test Friday. The Falcon 9 will be used to launch a commercial geostationary communications satellite no earlier than Monday at 7:10 p.m. EST (0010 GMT Tuesday).
