Gemini 3 was the first manned mission in NASA's Gemini program, the second American manned space 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 manned US spaceflight (including two X-15 flights over 100 kilometers), and the 17th world human spaceflight including eight Soviet flights. It was also the final manned 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.
