Live coverage: Veteran three-man crew docks with space station

A Canadian space flier will join three NASA crew members on the first piloted flight of the Space Launch System and Orion spacecraft around the moon, becoming the first non-U.S. astronaut on a lunar voyage, officials announced last week.

Working via remote control this spring, scientists will spark a fire aboard the unmanned Cygnus cargo ship that launches Tuesday to study how the deliberate flames spread in weightlessness.

The Atlas 5 rocket emerges Monday from the Vertical Integration Facility for rollout to Complex 41 at Cape Canaveral in preparation to launch the Orbital ATK Cygnus resupply ship to the International Space Station.
