- In Space: No
- Height: 6.3 m
- Diameter: 3.07 m
- Status: Single Use
The Cygnus NG-11 “S.S. Roger Chaffee” spacecraft embarked on 1 flight(s), showcasing its capability of Cargo Earth Orbit Logistics and designed with a flight life of 1 week to 2 years design life.. Notably, it boasts a crew capacity accommodating up to Array astronauts and a payload capacity of 3750 kg.
Cygnus NG-11, previously known as CRS OA-11, is the twelfth planned flight of the Northrop Grumman robotic resupply spacecraft Cygnus and its eleventh flight to the International Space Station under the Commercial Resupply Services contract with NASA. The mission is scheduled to launch on 17 April 2019. This is the last mission from the extended CRS contract; followup missions are part of the CRS2 contract.

History
Cygnus is a spacecraft developed originally by Orbital ATK and then acquired by Northrup Grumman after an acquisition. It is used to transport cargo to the ISS.
The first operational mission of Cygnus to the ISS was in September 2013.
One flight on 28 October 2014 ended in a failure when the Antares launch vehicle, used to launch the Cygnus, exploded shortly after launch. This set back the Cygnus launch schedule over a year. Following the launch anomaly a new version known as ‘Cygnus Enhanced’ was flown. This extended the Cygnus length and allowed it to carry an extra 700kg to the ISS.
The Cygnus spacecraft is launched aboard Antares, Atlas V, or Falcon 9 to deliver cargo to the ISS under NASAs CRS contracts. It has no heatshield so at the end of its mission its used to dispose of waste by burning up in the Earths atmosphere.
