Q&A with Keith Gendreau, principal investigator of the first X-ray space communications experiment (members only)

Two days after launching from Cape Canaveral with nearly 5,500 pounds of supplies and experiments, an automated SpaceX Dragon cargo craft approached the International Space Station Monday. The Dragon supply ship was grappled by the station’s robotic arm at 7:01 a.m. EDT (1101 GMT).

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.

SpaceX launched a Falcon 9 rocket from California’s Central Coast at 10:42:18 a.m. PST (1:42:18 p.m. EST; 1842:18 GMT) Sunday with the Jason 3 oceanography satellite. A secondary objective of the mission to recover the first stage on a barge in the Pacific Ocean failed.
