Watch the Falcon 9 launch from pad 39A

SpaceX is more than a week into a company-led probe of a launch pad explosion Sept. 1 that destroyed a Falcon 9 booster and an Israeli communications satellite, but the investigation so far has turned up no smoking gun on the cause of the mishap, Elon Musk said Friday.

NASA Administrator Jim Bridenstine says he is “fairly confident” that astronauts can fly to the International Space Station aboard SpaceX’s Crew Dragon spaceship at the end of May or early June, pending final parachute tests, data reviews and a training schedule that can escape major impacts from the coronavirus pandemic.

Two astronauts floated outside the International Space Station Sunday for the first in a series of spacewalks to upgrade the lab’s aging solar power system, assembling a support fixture that eventually will hold a new solar blanket.
