The S.S. Katherine Johnson will now deploy five CubeSats via two separate CubeSat deployers, Slingshot and Nanoracks. This Cubesat deployment includes Dhabisat, the second CubeSat developed by Khalifa University in Abu Dhabi, United Arab Emirates. Dhabisat was developed as part of Khalifa’s Space Systems and Technology Concentration, a joint program developed in collaboration with UAE-based satellite operator Al Yah Satellite Communications Company (Yahsat) and Northrop Grumman.

“Our Cygnus cargo resupply missions to the International Space Station help enable humans to live and work in space,” said Frank DeMauro, vice president and general manager, tactical space systems, Northrop Grumman. “With each mission, we grow our capabilities beyond cargo resupply as we operate a high performing science laboratory for both civil and commercial companies during the secondary phase of our flight.”

The NG-15 Cygnus spacecraft was launched on Feb. 20 aboard Northrop Grumman’s Antares rocket, carrying nearly 8,000 pounds of scientific research, supplies and equipment to the astronauts living on the station. The vehicle has been berthed with the orbiting laboratory since Feb. 22.
