Live coverage: Cygnus spacecraft arrives at space station

Closing out 52 days at the International Space Station, an automated Northrop Grumman Cygnus cargo craft left the research outpost Sunday to climb into a higher orbit for deployment of six CubeSats and further engineering experiments, before de-orbiting over Pacific Ocean later this month.

NASA says it is interested in flying astronauts and scientists on commercial suborbital vehicles, like those being tested by Virgin Galactic and Blue Origin, to provide additional training and research opportunities augmenting missions to the orbiting International Space Station.

Arianespace chief executive Stephane Israel announced an anomaly occurred during Thursday’s flight of an Ariane 5 rocket from Kourou, French Guiana, shortly after the launcher’s second stage engine ignited.
