Video: Falcon 9 hot fire

The 60 satellites SpaceX is set to launch Wednesday night, beginning the build-out of a broadband network of orbiting spacecraft that could eventually number thousands, are based on a new flat-panel design, with krypton-fueled plasma thrusters, high-power antennas, and a capability to autonomously steer away from other objects in space.

SpaceX is set to retire its current fleet of Dragon capsules, in use since 2010, next year and begin flying supplies to the International Space Station on a new variant of the Dragon spacecraft based on the model in development to carry astronauts.

SpaceX’s next launch from Cape Canaveral is set for Feb. 24, when a Falcon 9 rocket will carry a commercial television broadcasting satellite aloft for Luxembourg-based SES, the payload’s owner announced Monday.
