A two-stage Northrop Grumman Antares booster lifted off Nov. 2 from the Mid-Atlantic Regional Spaceport on Virginia’s Eastern Shore with a Cygnus cargo freighter on the way to the International Space Station.

Liftoff of a previously-flown Falcon 9 rocket is set for 6:27 p.m. EDT (2227 GMT) Thursday from NASA’s Kennedy Space Center in Florida, the first time SpaceX has reused one of its first stage boosters on a second mission. Ground crews face a tight timeline to ready the rocket and the SES 10 communications satellite in time for a Thursday launch attempt.

United Launch Alliance workers encapsulated the freighter on Wednesday with the 14-foot-diameter, 45-foot-long extra extended payload fairing (XEPF) at Kennedy Space Center’s Payload Hazardous Servicing Facility.
