The Apollo program produced the first images that
introduced us to Earth as a colorful marble floating
in black space, which revolutionized public
perception of our fragile planet. Mariner 10 and
Voyager 1 both took such snapshots, as did Mars
Odyssey and Venus Express. Other spacecraft traveling
to other planets like Galileo, Rosetta, and MESSENGER,
shot photos and even movies as they flew by. Some
planetary travelers - like Voyager 1, Mars Global
Surveyor, Cassini, and even the Mars Exploration
Rover Spirit - were even able to turn back toward
Earth and capture distant glimpses of their home
planets from their eventual destinations.
