Live coverage: Station crew lands after 11 months in orbit

In a reshuffling of SpaceX’s launch schedule, a Falcon 9 rocket is set for liftoff no earlier than Dec. 8 on a mission to deliver several tons of supplies and experiments to the International Space Station and return to service a Cape Canaveral launch pad damaged in a catastrophic rocket explosion last year.

Concluding 80 days attached the International Space Station, the commercial Cygnus cargo ship will be detached to fly away Tuesday for an unprecedented onboard fire experiment before re-entering the atmosphere next week.

Officials from the Norwegian Space Center are looking for another launch opportunity for a microsatellite designed to track ship traffic and study space weather after engineers determined it could not safely be attached to a Soyuz rocket set for liftoff Friday.
