I am not sure that Apollo 11 really fits there if the criteria is "changed history." An epic undertaking, a triumph of human endeavor, to be sure. But I don't see that it's changed history yet. It may, but it may end up being a dead-end, like the European colonization of Greenland (not the Erik the Red effort, but the one where they imported stained glass windows for their church rather than stuff they needed).
I look at it in the same way as I look at the Basque discovery of the new world when finding cod fishing grounds. An adventure, they were first, sure. But since nothing in history followed it, there's no "changed history" aspect to it.
