Apollo Program
Apollo / Highwater / Pegasus / AAP / Skylab / ASTP
NASA's Apollo Program ran from 1961 to 1972 and was the culmination of the earlier Mercury and Gemini projects, and fulfilled president Kennedy's promise of Americans on the Moon by the end of the decade. It landed the first human on the moon, with 11 to follow. Astronauts Gus Grissom, Ed White, and Roger Chaffee were lost during a fire in the Apollo 1 capsule, and Apollo 13 aborted its moon landing because of an explosion in its Service Module.
To accomplish its goals the program developed the Little Joe II, Saturn I, IB and V rockets, Command, Service and Lunar modules, a Lunar Rover, 3 types of lunar lander simulators, and a Particles and Fields sub-satellite, not to mention the vast array of development, service and launch infrastructure.
Several sub-programs ran alongside or after the main program. Project Highwater released large volumes of water into the ionosphere to understand the effects of large volumes of propellant being released in the event of a high altitude rocket explosion. The Saturn I Block II launched three Pegasus satellites studying the frequencies of micrometeorite impacts on spacecraft.
The Apollo Applications Program (AAP) would build upon the technology and infrastructure of the Apollo Program, but because of budget cuts, only the Skylab space station and the Apollo–Soyuz Test Project (ASTP) would be implemented. Skylab was built out of an S-IVB upper stage with Apollo Telescope Mount (ATM) and launched on the final Saturn V rocket. Three 3 astronaut crews would fly to it to conduct science. The ATSP flight docked with a Soviet Soyuz spacecraft, and was the last Apollo capsule to launch.
