A dry run for the more momentous Apollo 11--the one with Neil Armstrong--launched a few months later, it did all the same things, but minus a lunar landing. OK, that's one helluva minus. Let's see if I can get some addition going here
Stafford, Cernan, and Young were the second crew to orbit the moon. That's the command module above. So who got close enough to photographed it?
Either Cernan or Young, who flew the odd-looking contraption above, the Lunar Module.
Somewhere along the way somebody snapped a picture of an "Earthrise". It wasn't the first such picture, as an earlier (and more iconic) photo was taken on Apollo 8 in December, 1968.
In fact, Apollo 10 seemed destined to be the least iconic of all the 1960s space flights. Second moon orbit, second Earthrise, a lunar lander that never actually landed. Yet it was necessary. So how to make it more interesting, more entertaining, to the taxpaying public footing the bill? NASA turned to a pop culture phenomenon bigger than even the space program itself.
That's the Command Module on the left, the Lunar Module on the right.
The petting threatened to turn heavy.
I know that one fellow's behavior might seem a bit boorish (or worse), but, remember, it was the 1960s. As Tom Wolfe and others have pointed out, the astronauts of that era tended to be on the horny side.
Perhaps with some encouragement.
