Today we mourn the passing of Thomas P. Stafford at the age of 93. In December 1965, Stafford piloted Gemini VI, the first rendezvous in space, and helped develop techniques to prove the basic theory and practicality of space rendezvous. Later he commanded Gemini IX and performed a demonstration of an early rendezvous that would be used in the Apollo lunar missions, the first optical rendezvous, and a lunar orbit abort rendezvous. He served as the commander of the Apollo 10 ‘dress rehearsal’ mission preparing for the first Moon landing and as Apollo commander of the Apollo-Soyuz Test Project (ASTP) mission, a joint space flight culminating in the historic first meeting in space between American Astronauts and Soviet Cosmonauts, which ended the International space race. Throughout his career, Stafford helped us push the boundaries of what's possible in air and space, flying more than 100 different types of aircraft.
