What were the results of the Apollo 11 mission?

There are two primary outcomes from the Apollo 11 mission. The first, and most important, was that man could travel to the moon, land on its surface, get out and walk around on its surface without sinking under the soil (a real concern many held prior to launch), get back into the spacecraft, rendezvous with the orbiting Command Module, and return safely to Earth. That was the primary, and most important goal, of the Apollo 11 mission.

Less important, at least for this mission, was the return of samples and pictures and the placement and execution of some small science experiments on the lunar surface. These were all performed, and the science was important, but it was not the primary goal of the mission.
