Live coverage: Kennedy Space Center to reopen Friday

A SpaceX Falcon 9 rocket lifted off from Vandenberg Air Force Base in California at 10:17:10 a.m. EDT (7:17:10 a.m. PDT; 1417:10 GMT) Wednesday with the Radarsat Constellation Mission for the Canadian government. The Falcon 9’s first stage successfully landed back at Vandenberg around eight minutes later.

United Launch Alliance early Thursday delayed the launch of a triple-core Delta 4-Heavy rocket — the largest launcher in the company’s fleet — until Saturday to allow engineers more time to resolve an issue with a ground pneumatics control system.

SpaceX is targeting April 8 for the launch of its first resupply run to the International Space Station in nearly a year, a mission that the company hopes will mark the start of a rapid-fire launch manifest full of payloads waiting to fly.
