Live coverage: Soyuz crew lands in Kazakhstan

The second fully commercial astronaut flight to the International Space Station will have just two opportunities to launch Sunday and Monday, or else wait until after an upcoming SpaceX resupply mission next month to deliver a new set of high-priority solar arrays to the complex.

Ground crews transferred an Antares rocket out of an assembly building to a launch pad on Virginia’s Eastern Shore in a major step before liftoff on Orbital Sciences’ third flight to resupply the International Space Station.

NASA and Orbital ATK have agreed to schedule the launch of the next Cygnus supply ship for Nov. 10 from Wallops Island on Virginia’s Eastern Shore, a delay of a month from the mission’s earlier target launch date to allow the flight to carry more cargo to the International Space Station, officials said.
