Two days after lifting off from Florida’s Space Coast, a Dragon cargo capsule packed with more than 6,400 pounds of research experiments and crew supplies arrived at the International Space Station on Wednesday. Astronaut Jack Fischer used the station’s robotic arm to grapple the supply ship at 6:52 a.m. EDT (1052 GMT).

An International Launch Services Proton rocket lifted off at 2137 GMT (4:37 p.m. EST) on Dec. 27 with the Astra 2G communications satellite, a new broadcasting platform owned by SES to beam television and broadband services to Europe, Africa and the Middle East.

This is video footage documenting preparations for the commercial Orbital ATK Cygnus cargo freighter to perform the OA-7 mission to the International Space Station. Activities occurred at the Kennedy Space Center’s Space Station Processing Facility and the Payload Hazardous Servicing Facility. The craft will be boosted into orbit by a United Launch Alliance Atlas 5 rocket on April 18 at 11:11 a.m. EDT (1511 GMT).
