Mars 2001 is a collection of over 100 concept maps created at the Center for Mars Exploration at NASA Ames, is used to navigate over a huge collection of resources on the WWW2.

• Students of all ages navigate through the concept maps as a way to both learn from the expert’s knowledge and to reach the diverse media that are linked to the concept maps.
• Mars 2001 is an excellent example of how concept maps can be used to organize content in a non-linear fashion, using the expert’s knowledge as the organizational structure, truly standing in the shoulders of giants in the creation of these knowledge models.
• Of particular interest is the fact that in the case of Mars 2001, the expert (Dr. Geoff Briggs) constructed the maps himself (and with some help from colleagues) and there were no knowledge elicitation sessions and maps constructed by knowledge engineers, as was the case of Nuces and El-Tech.
