The Exploratorium always has wonderful interactive features, and this collection is no exception to that trend. This particular offering includes updates from Will Curiosity, NASA's newest rover, which is currently exploring the surface of Mars. Meanwhile, many on Earth wonder whether or not the craft will find evidence that conditions on Mars have ever been favorable for microbial life. The webcasts here profile Curiosity's wanderings, with over twenty archived features. Each webcast features stunning images and expert commentary by a range of staff and visiting scientists. First-time visitors can make their way through overviews of previous explorations by looking at the features "Spirit and Opportunity" and "Highlights of Early Missions." Another nice feature is that four of the webcasts are available in Spanish.
