Photos: Falcon takes flight

A powerful commercial communications satellite driven by plasma thrusters rode a reused SpaceX Falcon 9 rocket booster away from Cape Canaveral early Monday, climbing into orbit to connect companies, homes, airplanes and ships across much of the Eastern Hemisphere.

The Falcon 9 rocket set to launch the SpaceX’s Crew Dragon capsule on a test flight in February briefly ignited its Merlin main engines on pad 39A at NASA’s Kennedy Space Center in Florida on Thursday. The Crew Dragon test flight to the International Space Station is a precursor to the spaceship’s first mission with astronauts later this year.

SpaceX called off the launch of a Falcon 9 rocket from Cape Canaveral on Wednesday to make sure the booster’s supply of super-chilled cryogenic liquid oxygen is cold enough to support the delivery of the 5.8-ton SES 9 commercial communications satellite to an orbit nearly 25,000 miles above Earth.
