JFK's 'moon speech' at 60: Remember Apollo, and what made it possible

I was thrilled with the 1st Moon landing and Neil Armstrong's memorable words. I was soberly riveted to the news as Apollo 13 "limped" back to Earth. I still hold the concept and feeling that Space is both an exhilarating adventure fraught with the unknown dangers akin to the discovery of the New World, and the crushing reality of Nature, hubris and carelessness. In fact, Space may be the "biggest leap" into the future for the species, if we can succeed.
