Getting to the moon was, of course, a communal effort. It couldn’t have been done without the work of thousands of engineers and support staff, without the political will of the whole USA, and without the inspiration of dreamers throughout the ages. It wasn’t just Neil Armstrong’s achievement.
But he was still the one who got into a rocket, knowing there was a strong chance it would kill him, and travelled further than any human being had ever travelled before. He left his footprints on another world.
Whatever one’s views on manned space-flight, one thing is sure — should intelligence on this planet last long enough, one day we will have explored, and possibly settled, space as far as the limits of the laws of physics will allow. And whatever worlds our (intellectual or physical) descendants inhabit, they will do so in part because of Neil Armstrong.
