Passport to Knowledge created this website to present the cutting edge research and new discoveries made possible by the Mars Exploration Rovers. Students can find general information and a history of the exploration of the Red Planet. The site features biographies and interviews with many of the exploration researchers. Educators can discover many fun, hands-on activities that can be added to their curriculum. The collection of videos of the Mar's adventures is a fabulous part of the site. Visitors can also find links to resources in Spanish.
