"For millennia, Mars has stimulated our imaginations. First we saw Mars as a wandering red star, a bringer of war from the abode of the gods.
In recent centuries, the planet's changing appearance in telescopes caused us to think that Mars had a climate like the Earth's.
Our first space age views revealed only a cratered, Moon-like world, but later missions showed that Mars once had abundant liquid water.
Through it all, we have wondered: Has there been life on Mars? To those taking the next steps to find out, we wish a safe journey and the joy of discovery."
