A Northrop Grumman Cygnus cargo ship arrived at the International Space Station on Monday, delivering nearly four tons of supplies and experiments to the research lab and its crew, including a $23 million titanium toilet and a high-definition virtual reality camera planned for use on a future spacewalk.

The two structural elements of Orbital ATK’s OA-7 Cygnus space freighter were delivered to Kennedy Space Center for final assembly, the packing of cargo and launch to the International Space Station.

The Atlas 5 rocket emerges Monday from the Vertical Integration Facility for rollout to Complex 41 at Cape Canaveral in preparation to launch the Orbital ATK Cygnus resupply ship to the International Space Station.
