A SpaceX Falcon 9 rocket will launch Northrop Grumman’s 21st Cygnus cargo freighter on the 20th operational cargo delivery flight to the International Space Station. The mission is known as NG-20. The launch vehicle for this mission was changed from Northrop Grumman’s own Antares 230+ rocket to SpaceX’s Falcon 9 rocket after Russia’s invasion of Ukraine ended engine and booster production for the Antares program. Delayed from October.
