The Orbital ATK Cygnus pressurized cargo module is mated to the service module at NASA's Kennedy Space Center.
In the Space Station Processing Facility at NASA’s Kennedy Space Center in Florida, technicians and engineers prepare the Cygnus pressurized cargo module for mating to its service module. Cygnus is being prepared to deliver thousands of pounds of supplies, equipment and scientific research materials on the Orbital ATK CRS-7 mission to the International Space Station. Scheduled to launch on March 24, 2017, the commercial resupply services mission will lift off atop a United Launch Alliance Atlas V rocket from Space launch Complex 41 at Cape Canaveral Air Force Station.
