Public Gets a Chance to Use Instrument Similar to One Headed for Mars University of Arizona

The UA Lunar and Planetary Laboratory’s Gamma Ray Spectrometer Team has created an exhibit that describes the Gamma Ray Spectrometer (GRS) Instrument, part of the 2001 Mars Odyssey mission now on its way to Mars. The Mars Odyssey was launched on April 7, 2001 and is expected to arrive at Mars on Oct. 24 of this year. The Park Place exhibit allows participants to use and understand spectrometers, a key technology used in the GRS instrument. At the exhibit, spectrometer is used to view different kinds of lights. The spectrometer breaks the light into its individual colors and allows the chemicals in each bulb to be identified because of their unique, beautiful color patterns.
