Live coverage: Falcon 9 rocket lifts off with Radarsat satellites

Forecasters predict mostly cloudy conditions and a chance of light rain for Tuesday morning’s scheduled takeoff of a SpaceX Falcon 9 rocket with a space station-bound supply ship, with a 40 percent chance weather could prevent liftoff during an instantaneous predawn launch opportunity.

A European Vega rocket took off Tuesday from a tropical launch pad in South America with Mohammed VI-A, a Moroccan spy satellite built in France.

There were more successful space launches in 2014 than in any year since 1992, with Russia, the United States and China responsible for more than 80 percent of global launch activity.
