Galileo:
The Galileo spacecraft found evidence of life on Earth. Not a surprising discovery, but the use of instruments to detect traces of life in a planet's atmosphere will be useful as future space probes continue to seek evidence of life beyond Earth.
Providing another alience point of view, Galileo's cameras captured unique never-before-seen views of Antarctica and also the Earth and Moon together - a glimpse at what someone from another world might see as they approached our little piece of the solar system.
