Launched on December 4, 1996, NASA's Pathfinder impacted the surface of Mars on July 4, 1997 with the first Mars rover called the Sojourner. The Mars Pathfinder impacted the surface on July 4 at a velocity of about 18 m/s (40 mph) and bounced about 15 meters (50 feet) into the air, bouncing another 15 times and rolling before coming to rest approximately 2.5 minutes after impact and about 1 km from the initial impact site. The landing site has since been named the Carl Sagan Memorial Station. The Mars Pathfinder's Sojourner Rover rolled onto Mars' surface on July 6 with images showing the rover completely off the ramp, all six wheels on the martian soil. A 9-frame movie of the Sojourner's descent down the ramp is also available from this site (~500 K). This site has many images and a video.   less

Cornell University, NASA's JPL and Bill Nye present information on the Mars Exploration Rovers. Images, at-home experiments for kids and lesson plans compliment details of mission goals and payload. " The two powerful new Mars rovers have far greater mobility than the 1997 Mars Pathfinder rover. These identical robotic explorers were originally thought to be able to trek up to 100 meters (about 100 yards) a day ("sol") across the martian surface, but on March 31, 2005 Opportunity traveled a distance of 220 meters (722 feet) in a single day. This is farther than the Sojourner rover's travel throughout its entire mission. Each rover carries a sophisticated set of instruments â?? the Athena Science Payload â?? that has allowed it to search for evidence of liquid water in the planet's past."   less

NASA's site for kids, students, educators and press on its Mars exploration program. "Since our first close-up picture of Mars in 1965, spacecraft voyages to the Red Planet have revealed a world strangely familiar, yet different enough to challenge our perceptions of what makes a planet work. Every time we feel close to understanding Mars, new discoveries send us straight back to the drawing board to revise existing theories. You'd think Mars would be easier to understand. Like Earth, Mars has polar ice caps and clouds in its atmosphere, seasonal weather patterns, volcanoes, canyons and other recognizable features. However, conditions on Mars vary wildly from what we know on our own planet. Rocky Terrain and Pink Sky at Pathfinder Landing Site Over the past three decades, spacecraft have shown us that Mars is rocky, cold, and sterile beneath its hazy, pink sky. We've discovered that today's Martian wasteland hints at a formerly volatile world where volcanoes once raged, meteors plowed deep craters, and flash floods rushed over the land. And Mars continues to throw out new enticements with each landing or orbital pass made by our spacecraft."   less

The overarching goal of the Informedia initiatives is to achieve machine understanding of video and film media, including all aspects of search, retrieval, visualization and summarization in both contemporaneous and archival content collections. The base technology developed under Informedia-I combines speech, image and natural language understanding to automatically transcribe, segment and index linear video for intelligent search and image retrieval. Informedia-II seeks to improve the dynamic extraction, summarization, visualization, and presentation of distributed video, automatically producing ??collages?ù and ??auto-documentaries?ù that summarize documents from text, images, audio and video into one single abstraction. Informedia's MPEG collection is available through The Open Video Project, a shared digital video collection developed at the Interaction Design Laboratory at the School of Information and Library Science, University of North Carolina Chapel Hill. The Open Video Project repository is hosted as one of the first channels of the Internet 2 Distributed Storage Infrastructure Initiative,a project that supports distributed repository hosting for research and education in the Internet 2 community. The collection is also available at the NSDL site. Full text search across the video segments is available. For example, to see all the items in the collection, search on "Informedia at Carnegie Mellon University" at the NSDL site. To see just the video segments contributed by Informedia dealing with volcanoes and Mars, search on "Informedia volcano Mars" (with the 2004 NSDL design, clicking on the "more info" link shows metadata associated with the video segment, including a Description" field which holds the text transcript for the video segment). The content was made available on this site through the Open Archives Initiative Protocol for Metadata Harvesting, developed by the Open Archives Initiative.   less

JPL site for Mars Exploration Rovers. Will be updated with the new rover Curiosity. Separate sections for kids, students and tachers. "NASA's twin robot geologists, the Mars Exploration Rovers, launched toward Mars on June 10 and July 7, 2003, in search of answers about the history of water on Mars. They landed on Mars January 3 and January 24 PST, 2004 (January 4 and January 25 UTC, 2004). The Mars Exploration Rover mission is part of NASA's Mars Exploration Program, a long-term effort of robotic exploration of the red planet. Primary among the mission's scientific goals is to search for and characterize a wide range of rocks and soils that hold clues to past water activity on Mars. The spacecraft are targeted to sites on opposite sides of Mars that appear to have been affected by liquid water in the past. The landing sites are at Gusev Crater, a possible former lake in a giant impact crater, and Meridiani Planum, where mineral deposits (hematite) suggest Mars had a wet past. After the airbag-protected landing craft settled onto the surface and opened, the rovers rolled out to take panoramic images. These images give scientists the information they need to select promising geological targets that tell part of the story of water in Mars' past. Then, the rovers drive to those locations to perform on-site scientific investigations."   less
