NASA flight director discusses curtailed spacewalk

A Russian Progress supply ship packed with 3.1 tons of cargo and propellant to refuel the International Space Station is set for liftoff Tuesday from the Baikonur Cosmodrome in Kazakhstan.

The Cargo Dragon spacecraft, tail number C209, will carry 6,659 lbs. (3,021 kg.) of science and supplies to the orbiting outpost. Liftoff from pad 39A at NASA’s Kennedy Space Center happened Monday, April 21, at 4:15 a.m. EDT (0815 UTC).

Orbital ATK shipped the final major piece of hardware for the next Cygnus space station resupply mission to a launch base on Virginia’s Eastern Shore last week as technicians began loading cargo destined for delivery to the orbiting research lab.
