NASA flight director discusses curtailed spacewalk

NASA has a builder to construct a five-ton spacecraft to catch up with the aging Landsat 7 Earth observation satellite and refuel it in 2020, employing robotic tools mastered in years of rehearsals on the International Space Station.

Packed with an array of experiments and provisions, including a custom-made Italian espresso maker, SpaceX’s unmanned Dragon cargo capsule reached the International Space Station on Friday after a precise laser-guided rendezvous more than 250 miles above Earth.

Christopher Ferguson, commander of the final space shuttle flight and now a Boeing executive, has stepped down as commander of the first piloted test flight of the company’s troubled CST-100 Starliner commercial spacecraft, he and Boeing announced Wednesday. He has been replaced by NASA astronaut Barry “Butch” Wilmore.
