Solar-Go-Round September 30, 2010

Take a tour of the Solar System, from the radiant Sun and the ringed planet Saturn, to giant Jupiter and far-away Pluto. Discover what makes the planets go round, then design a solar system and launch your planets into orbit. Find out how rocks from outer space can change a planet's surface and climate, then try making craters yourself. Hunt for signs of water on other planets, find out about the weather on Mars and Titan, and learn how telescopes and robotic spacecraft are helping us explore our planetary neighbors.
