Cygnus CRS Orb-3, also known as Orbital Sciences CRS Flight 3 or Orbital 3, was an attempted flight of Cygnus, an automated cargo spacecraft developed by United States-based company Orbital Sciences, on 28 October 2014.The mission was intended to launch at 6:22 PM that evening. To buy Orbital ATK, it paid $7.8 billion in cash and assumed $1.4 billion in debt. But in the meantime, Orbital ATK needed to launch cargo to the space station. Orbital ATK’s cargo resupply mission will deliver over 5,100 pounds of science and research, supplies and hardware to the space station.

Orbital ATK is developing a new family of rockets to compete with SpaceX, United Launch Alliance and other companies for government and commercial customers. The Orbital ATK Antares rocket, with the Cygnus spacecraft onboard, is seen on launch Pad-0A, Friday, Nov. 10, 2017 at NASA's Wallops Flight Facility in Virginia. The Orbital ATK Antares rocket, with the Cygnus spacecraft onboard, is seen on launch Pad-0A as the moon sets, predawn, Saturday, Oct. 15, 2016 at NASA's Wallops Flight Facility in Virginia. Orbital ATK’s eighth contracted cargo resupply mission with NASA to the International Space Station will deliver approximately 7,400 pounds of science and crew supplies. The Antares will launch a Cygnus spacecraft on a cargo resupply mission to the International Space Station. An Orbital ATK rocket rolls out to launch Pad-0A at NASA's Wallops Flight Facility on May 17, 2018, in advance of a May 21 launch from Wallops Island, VA. Northrop Grumman announced the $9.2 billion deal on September 18.
