SpaceX fired up a Falcon 9 booster at Cape Canaveral’s Complex 40 launch pad Wednesday in advance of a space station resupply launch Dec. 12, returning the pad to service after a rocket explosion there last year.

Continuing a busy week of comings and goings at the International Space Station, a Russian Progress supply ship is set for liftoff at 0709 GMT (3:09 a.m. EDT) Wednesday from Kazakhstan with nearly 5,200 pounds of food, fuel and supplies for the six-person crew on the International Space Station.

International Space Station commander Jeff Williams set a new U.S. space endurance record Wednesday, his 521st day in orbit over four missions, eclipsing the 520-day record set earlier this year by astronaut Scott Kelly at the end of his nearly one-year stay aboard the lab complex.
