Time-lapse: The Falcon 9 and Crew Dragon roll to the launch pad (members only)

A day-and-a-half after launching from Virginia aboard an Antares rocket, a Northrop Grumman Cygnus supply ship loaded with nearly 7,600 pounds of experiments and provisions arrived at the International Space Station on Friday. Astronaut Anne McClain captured the Cygnus spacecraft with the space station’s Canadian-built robotic arm at 5:28 a.m. EDT (0928 GMT).

Stephen Clark, Spaceflight Now’s editor, asked NASA’s acting administrator about the space agency’s commercial crew and Artemis programs during a one-on-one virtual interview Tuesday, April 20.

NASA is sure enough that Boeing and SpaceX can safely launch astronauts to the International Space Station by early 2019 to hold off paying Russia to keep flying U.S. crews to the research complex, and one official says a deadline to order parts for new Russian Soyuz crew capsules may have already passed.
