While most Cygnus missions have been launched atop Northrop Grumman's Antares rocket from the Mid-Atlantic Regional Spaceport, NG-21 was the second of three missions planned to launch atop the Falcon 9 Block 5 rocket from the Cape Canaveral Space Force Station. Northrop Grumman exhausted the supply of its Antares 230+ rocket after the NG-19 ...

As an interim solution, Northrup Grumman contracted with its CRS competitor SpaceX to launch NG-20, 21 and 22 using its Falcon 9 Block 5 rocket. With the launch of NG-20, Cygnus becomes only cargo freighter to launch on four different orbital launchers, that is, Antares rocket (100 series), Atlas V , Antares 200 series and Falcon 9.
The Graphite-Epoxy Motor (GEM) is a family of solid rocket boosters developed in the late 1980s and used since 1990. GEM motors are manufactured with carbon-fibre-reinforced polymer casings and a fuel consisting of HTPB-bound ammonium perchlorate composite propellant. GEM is produced by Northrop Grumman Space Systems. [1]
Cygnus NG-18 was the seventh Cygnus mission under the Commercial Resupply Services-2 contract. Northrop Grumman Innovation Systems confirmed on 23 February 2021 that Thales Alenia Space of Turin, Italy, will fabricate two additional Pressurized Cargo Modules (PCMs) for a pair of forthcoming Commercial Resupply Services-2 missions. Current plans ...
The Minotaur VI is a five-stage launch vehicle proposed by Northrop Grumman that, as of 2024, has not flown. Minotaur VI is based on the Minotaur IV+, adding a second SR-118 first stage to increase performance. [5] A further enhanced variant, Minotaur VI+, is also proposed for beyond low Earth orbit missions using an added Star 37FM sixth stage ...
