Watch a live view of SpaceX’s Cape Canaveral launch pad (members only)

NASA has agreed to allow its astronauts to fly on reused Crew Dragon spaceships and Falcon 9 boosters beginning as soon as SpaceX’s third launch of a crew to the International Space Station, a mission expected to launch next year.

Running two days later after a last-minute abort Sunday, a Russian Progress resupply and refueling freighter lifted off in a blanket of fog Tuesday from the Baikonur Cosmodrome to deliver three tons of cargo, propellant and water to the International Space Station.

NASA is sending into orbit Monday night a spacecraft to test a safer type of rocket fuel, an ultra-precise atomic clock that could change the way missions navigate in deep space, and an experiment to examine the resiliency of electronics to radiation.
