Live coverage: Dragon completes space station resupply flight

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.

The next time astronauts land on the moon, they will ride to the lunar surface in a spacecraft that looks a lot different than the Apollo-era landing module last used in 1972. Lander concepts proposed by SpaceX, Blue Origin and Dynetics — which won a combined $967 million in NASA funding Thursday — take wildly different approaches to carrying crews to the moon.

SpaceX started the week with the launch of a Falcon 9 rocket from NASA’s Kennedy Space Center in Florida just after sunrise Monday, delivering a classified U.S. government spy satellite to orbit as the booster’s first stage returned to Cape Canaveral for a vertical landing.
