Edward H. White II
Selected as part of NASA’s Astronaut Group 2, Ed White became the first American to perform a spacewalk on the Gemini IV mission in 1965. Assigned to the first Apollo mission, White tragically died in the Apollo 1 fire in 1967.

James A. McDivitt
McDivitt was selected as an astronaut by NASA in September 1962 as part of NASA’s second astronaut class. He first flew in space as commander of the Gemini IV mission in June 1965. As the commander of Apollo 9, he played a critical role in the first flight of the complete set of Apollo hardware and the first flight of the Lunar Module.
S65-30427 (3 June 1965) — Astronaut Edward H. White II, pilot for the Gemini-Titan 4 (GT-4) spaceflight, floats in the zero-gravity of space during the third revolution of the GT-4 spacecraft. White wears a specially designed spacesuit. His face is shaded by a gold-plated visor to protect him from unfiltered rays of the sun. In his right hand he carries a Hand-Held Self-Maneuvering Unit (HHSMU) that gives him control over his movements in space. White also wears an emergency oxygen chest pack; and he carries a camera mounted on the HHSMU for taking pictures of the sky, Earth and the GT-4 spacecraft. He is secured to the spacecraft by a 25-feet umbilical line and a 23-feet tether line. Both lines are wrapped together in gold tape to form one cord. Astronaut James A. McDivitt, command pilot, remained inside the spacecraft during the extravehicular activity (EVA).
