42 years ago today we stepped into the realm of myth and legend.

Of all the events surrounding Apollo 11’s landing on the Moon on July 20, 1969, my most vivid recollection is its unreal quality. Neil Armstrong and Buzz Aldrin shuffled along the gray, dusty lunar surface, the Earth looming large in their sky, while Michael Collins, now the Moon’s own moon, orbited above them in lonely vigil. Yes, it was an astonishing technical achievement and a triumph for the United States. Yes, as Armstrong said as he first alighted, this was a historic step for the human species. But if you turned off the byplay between Mission Control and the Sea of Tranquility, with its deliberately mundane and routine chatter, you could glimpse that we humans had entered the realm of myth and legend.
