Video: Orion flight preps

Fifty years to the day after Neil Armstrong stepped onto the surface of the moon, a NASA astronaut, an Italian flight engineer and a Russian commander blasted off from Kazakhstan Saturday aboard a Soyuz spacecraft, chased down the International Space Station and glided in for a picture-perfect docking.

The first piloted flight of NASA’s Orion space capsule, a vehicle designed to carry astronauts away from Earth for the first time in two generations, may slip from 2021 to 2023, agency officials said Wednesday.

NASA managers have ruled out putting a crew on board an Orion capsule atop the agency’s huge Space Launch System rocket for the gargantuan booster’s maiden flight in 2019, citing technical risks and higher costs, up to as much as $900 million, agency officials said Friday.
