Live coverage: Atlas 5 rocket lifts off from Cape Canaveral

Ready for a resupply run to the International Space Station, a SpaceX Falcon 9 rocket was raised vertical at Cape Canaveral’s Complex 40 launch pad Wednesday ahead of a planned liftoff with more than 5,700 pounds of science experiments and crew supplies.

The first pair of four NASA CubeSats designed to provide frequent updates of typhoon and hurricane development for new insights into how tropical storms evolve and intensify were launched by Rocket Lab from its New Zealand spaceport on Sunday.

The scheduled launch Saturday of two commercial BlackSky Earth-imaging satellites from New Zealand will double as an opportunity for Rocket Lab to test an enhanced heat shield on its Electron booster, an upgrade that should allow the company to recover rockets in better condition for eventual reuse.
