When Neil Armstrong died the world lost one of humanity’s true heroes. It wasn’t just that he was the first man to ever step on the moon, or that he did so in a spaceship that had less power than your phone. What made Neil Armstrong so special was he never let fame go to his head.
As an interesting fact: the astronaut on the first photo you posted is not Neil Armstrong, it's Buzz Aldrin but you can see Neil Armstrong taking this very photo in the Aldrin's helmet shield.
