About the Mission
Northrop Grumman is proud to name the NG-15 Cygnus spacecraft after NASA mathematician Katherine Johnson, a Black woman who time and again broke through barriers of gender and race. It is a company tradition to name each Cygnus spacecraft after an individual who has played a pivotal role in human spaceflight. Her hand-written calculations were critical to America’s success during our first human spaceflight missions.
