Video: SpaceX launch scrubbed for upper level winds

A rocket recovery team positioned off Florida’s East Coast is standing by for liftoff Sunday of a Falcon 9 launcher with a space weather satellite, but the demanding trajectory of the flight adds more unknowns to the company’s dicey endeavor to land the booster on a ship at sea.

Tuesday is shaping up to be a busy day for SpaceX, with liftoff of a Falcon 9 rocket carrying a space weather satellite, an experimental booster flyback maneuver to test reusable launch technologies, and the splashdown of a Dragon capsule returning from the International Space Station.

A new space weather observatory to be stationed a million miles from Earth has been enclosed inside the nose cone of a SpaceX Falcon 9 rocket for liftoff Sunday from Cape Canaveral.
