An engineering model for NASA's Mars Science Laboratory makes its
way up a hill in the Mars Yard testing area at NASA's Jet Propulsion
Laboratory. The model, called "Scarecrow" because it does not include
a computer brain, is used for tests of mobility and landing.
The Mars Science Laboratory rover is in development for launch in 2009.
JPL, a division of the California Institute of Technology, Pasadena, manages
the mission for the NASA Science Mission Directorate, Washington.
