Gemini III was the first crewed mission in NASA's Gemini program. On March 23, 1965, astronauts Gus Grissom and John Young flew three low Earth orbits in their spacecraft, which they nicknamed Molly Brown.
This was the ninth crewed US spaceflight (including two X-15 flights over 100 kilometers (62 mi)), and the 17th world human spaceflight including eight Soviet flights.
It was also the final crewed flight controlled from Cape Kennedy Air Force Station in Florida, before mission control functions were shifted to a new control center located at the newly opened Manned Spacecraft Center in Houston, Texas.
