Cygnus NG-17 (Northrop Grumman-17) is a cargo resupply mission of the Northrop Grumman Cygnus spacecraft to the International Space Station under the Commercial Resupply Services (CRS) contract with NASA.

Northrop Grumman and NASA jointly developed a new space transportation system to provide commercial cargo resupply services to the International Space Station. The Cygnus cargo ship consists of two parts, a service module built in the USA based on the GEOStar platform, and a pressurized module, manufactured in France and Italy by Thales Alenia. The cargo is sent into orbit by a launcher specially developed for this purpose.

CRS NG-17 was captured by RMS on 21/02/2022 at 09:44 UTC and berthed to the Nadir port of the Unity module of the International Space Station on 21/02/2022 at 12:02 UTC. Its stay on the ISS was 127 days. It was unberthed on 28/06/2022 at 07:00 UTC and released by RMS on 28/06/2022 at 11:07 UTC. It deorbited on 29/06/2022 at 06:55 UTC.
