What was learned from the Apollo 11 Mission?
Mainly, that humans could successfully operate in space, far from Earth. In addition, the scientific data that returned from Apollo was essential to understand the history of how Earth (and the Moon) formed, how long it took, and what the early history of the Earth-Moon system was. In turn, this is essential information on how life arose on Earth . . . and whether it is likely (or not) that life arose elsewhere in space. Technologically, the Apollo program was an essential step in the development of space guidance systems, a new generation of rocket engine and fuels, fault-tolerant computing, and the operation and management of extremely complex systems. I hope that this has helped.
