Astronaut Karl G Henize signed Assess II - Galileo II NASA commemorative cover. Missions: STS-51-F. Henize applied for the first scientist-astronaut group, but was denied because the age limit was 35 and he was 37. In 1967, NASA abolished the age limit, and Henize was selected as a scientist-astronaut by NASA in August. Astronauts that did not already know how to fly had to complete a 53-week jet pilot training program at Vance Air Force Base, Oklahoma. They also completed initial education there. He was a member of the astronaut support crew and CAPCOM for the Apollo 15 mission. The entire support crew consisted of scientist-astronauts, as the prime crew of the mission thought they would need more help with the science aspects of the mission rather than the piloting. He was also a member of the astronaut support crew for the Skylab 2, 3, and 4 missions. He was mission specialist for the ASSESS-2 spacelab simulation mission in 1977. He logged 2,300 hours flying time in jet aircraft.
