Closing out a three-day chase from a launch pad in Virginia, Orbital ATK’s Cygnus cargo freighter arrived Thursday at the International Space Station with nearly 7,400 pounds of equipment, delivering food, a quantum physics experiment, and CubeSats for later deployment in orbit.

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.

Taking off and landing in the middle of the night at Cape Canaveral, a SpaceX Falcon 9 rocket successfully delivered a Dragon supply ship to orbit for the International Space Station as the launcher’s first stage booster swooped to a spectacular touchdown.
