Live coverage: Cygnus supply ship captured by space station robot arm

Members of NASA’s independent panel of aerospace safety advisors raised concerns last week about quality control problems that “seemingly have plagued” Boeing’s Starliner crew capsule program, while urging NASA to closely monitor SpaceX’s plans to reuse Crew Dragon spaceships on astronaut flights to the International Space Station.

NASA has ordered a second commercial crew ferry ship from SpaceX, NASA announced Friday, as the agency continues its on-going push to develop U.S.-built spacecraft to carry astronauts to and from the International Space Station, ending sole reliance on Russian Soyuz vehicles.

This is the pre-launch news conference held Dec. 2 at NASA’s Kennedy Space Center for liftoff of the Orbital ATK commercial Cygnus cargo ship aboard a United Launch Alliance Atlas 5 rocket for the International Space Station.
