Re: It was the first time the duo had been caught in the same frame.
Earthrise was not taken from the surface of the Moon. It was taken from Apollo 8. IIRC they weren't even in Moon orbit - they were on a free-return (to Earth) trajectory.
oops. from https://en.wikipedia.org/wiki/Apollo_8 'The crew orbited the Moon ten times over the course of twenty hours, during which they made a Christmas Eve television broadcast'.
