Maestro, a free download, is a scaled-down version of the program NASA scientists use to operate Spirit and Opportunity. As Spirit transmits data from Mars, it's regularly released to the Maestro site, and you can download that data to your copy of Maestro. Mac users, Linux users, Windows users, Solaris users -- you can all get in on the action. With the help of some Java code, you'll see 3-D color images of Mars, complete with detail and the ability to change perspective and zoom in and out.
