Live coverage: Proton blasts off on return-to-flight mission

A SpaceX Falcon 9 rocket lifted off from Vandenberg Air Force Base in California at 10:34 a.m. PST (1:34 p.m. EST; 1834 GMT) Monday. The launch, under contract to Spaceflight, carried into orbit 64 small satellites from 17 countries, the largest multi-payload rideshare mission ever flown on a U.S. rocket. The Falcon 9’s first stage booster previously flew on two missions from Florida, and landed again on a drone ship in the Pacific Ocean after Monday’s launch.

Two more roll-out solar arrays will ride a SpaceX cargo ship to the International Space Station this weekend, continuing a years-long mid-life station upgrade as NASA plans procurement of a final set of new solar wings to fully reinforce the lab’s power supply.

The EchoStar 23 communications satellite, on the way to a 15-year service life broadcasting television signals, launched aboard a SpaceX Falcon 9 rocket Thursday from pad 39A at NASA’s Kennedy Space Center in Florida.
