CYGNUS OA-9 is a commercial Cygnus cargo craft carrying a quantum research experiment, an investigation into the properties of concrete in space, fresh food and other provisions for the International Space Station's six-person crew. Ground teams loaded 7,205 pounds (3,268 kilograms) of hardware and provisions into the Cygnus spacecraft's pressurized compartment, built by Thales Alenia Space in Italy. Nine CubeSats packaged inside the Cygnus pressurized cabin will be transferred into the station's Japanese Kibo lab, where astronauts will place them in an airlock for retrieval by a robotic arm, which will position the nanosatellites for release into orbit in the coming months.
