A four-person crew rocketed into orbit Thursday from Cape Canaveral Space Force Station, Florida, heading for a six-month expedition on the International Space Station.
Riding a Falcon 9 rocket and Dragon spacecraft, the four crew members departed from Space Launch Complex-40 at Cape Canaveral at 11:10 am EDT (15:10 UTC) Thursday. Nine minutes later, they were in orbit to begin closing in on the space station for docking Thursday evening.
The launch was delayed from mid-September to replace a balky valve in the Dragon spacecraft's propulsion system, a task that involved cutting into a propellant line inside the ship to swap out a faulty component.
