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 ...

In August 2023, Northrop Grumman announced a further enlarged Mission B version of Cygnus, with a 1.5 m (4.9 ft) stretch to the payload module and payload mass increased to 5,000 kg (11,000 lb). This version is expected to enter service with the NG-23 mission in 2025 (the first to use the new Antares 330 launch vehicle).
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]
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.
Thiokol was an American corporation concerned initially with rubber and related chemicals, and later with rocket and missile propulsion systems. Its name is a portmanteau of the Greek words for sulfur (Greek: θεῖον, romanized: theion) and glue (Greek: κόλλα, romanized: kolla), an allusion to the company's initial product, Thiokol polymer.
For the PW1500G, N1 is the Low Pressure Spool, with a nominal speed of 10,600 RPM, with the fan geared with a ratio of 1:3.0625 (nominal speed 3461 RPM). [97] The top of climb is the most demanding point for a turbofan, where the compressor spins the fastest. [ 98 ]
