Northrop Grumman developed the Cygnus spacecraft to deliver critical cargo safely and reliably to the International Space Station. Since 2014, Cygnus has delivered over 138,000 pounds of supplies, equipment and experiments to the crew aboard the station. Cygnus also serves a vital role removing waste from the station and reboosts the station’s orbit.
Northrop Grumman's Antares rocket is a two-stage vehicle with optional third stage that provides low-Earth orbit launch capability for payloads weighing up to 8,000 kg. Today the rocket is primarily used to support the company's Commercial Resupply Services contract with NASA.
