Amazing article and incredible pictures, but this one line has me scratching my head: "Only 24 people have journeyed far enough to see the whole Earth against the black of space" The Apollo missions from 8 through 17, with the exception of Apollo 9 (LM test in Earth orbit), all reached lunar orbit, even if 8, 10, and 13 didn't actually land. Each carried 3 crew members. Doesn't that make 27 people?
