In this lesson students explore the idea of water on Mars. Many active links allow the students to come to their own conclusions about water on Mars and explore how Earth might appear from space without water. Other links provide the students with the opinions of experts. This is the eighth in a series of interactive student lessons from the Martian Sun Times. Full description.

NASA's Jet Propulsion and Mars Science Laboratories provide a detailed look "under the hood" of the Mars Curiosity Rover, explaining the role of the analytical chemistry instruments found onboard Curiosity. Curiosity's primary mission goal is to determine the habitability of the Gale Crater, which scientists believe was once filled with water. Curiosity is basically an entire chemistry lab packed ...

This interactive activity lets you explore the Gusev Crater on Mars in 3D. This is the landing site for the MER rover in January 2004. The 3D model was created using data from orbiting spacecraft. You can examine the surface from a distance, changing lighting to enhance features, and fly over the surface, looking for markers hidden in the terrain. Full description.

This 46 minute radio broadcast discusses the NASA announcement in March 2004 that the rover Opportunity explored a crater on Mars that was once soaked with water - the most convincing evidence yet of a warm, wet past on Mars. Though the question of whether that water may have supported life remains, it certainly improves the odds. The second part of the broadcast discusses genetically engineered organisms. ...

NASA Investigators working with Mars Odyssey data may have discovered remnants of snow packs that have created a system of gullies in crater walls and other, more unusual places such as ridge crests, sand dunes, and hilltops. Readers of this journal article can learn about the snow packs and their potential to collect and shelter water beneath themselves, possibly providing a favorable environment ... Full description.

MOLA-based animations showing Martian topography as both color and elevation. The exaggeration is 3x. This was created for a talk James Garvin will give on The Hill in late April 2002. Full description.

The Students for the Exploration and Development of Space (SEDS) provide information on the history and future of Mars exploration. Links are offered when necessary to cover as much information as possible. Hubble Space Telescope images of the planet are given, as well as other images. Life on Mars and Martian lore are also explored. A comprehensive look at investigations covers missions and observations ... Full description.
