Launched in October 1998, this website strives to be a real-time, living encyclopedia of robotic exploration of our solar system. We aim to provide the public with reliable, accurate, up-to-date information about the planets, moons, asteroids, comets and everything else in our solar system. We also provide a complete historical record of deep space exploration.
