Rocket lifts off after fire

SPACEX has launched a Falcon 9 rocket for the first time since a fireball on a Florida launch pad more than four months ago.

The two-stage rocket lifted off from Vandenberg Air Force Base, in California, on the weekend to place 10 satellites into orbit for Iridium Communications Inc.

SpaceX officials say they identified all possible causes of the September 1 accident and took corrective action.

The company’s rockets were grounded during the investigation.

The return to flight is a key step for SpaceX, a California-based company that has about 70 launches in line, worth more than $10 billion.
