October 24, 2001 NASA’S Mars Odyssey entered in orbit. December 15, 2001Mars Odyssey becomes the longest operating spacecraft. The odyssey continues to collect thousands of images and data about Martian geology , climate ,and mineralogy. The Odyssey spent 917 earth days doing its job Then the Odyssey served as communication relay base for the Mars Exploration Rovers
Boeing’s Delta II 7925 (Launched on April 7, 2001at 11:02a.m.[Eastern time](Arrived at Mars on October 24,2001) Supersonic parachute Sojourner rover (1997) Curiosity rover (2012) Spirit/Opportunity rover (2004)
America sent Mars odyssey to determine whether life ever arose on Mars Find out about the climates of Mars Find out about geology of Mars Get ready for humans to explore
Mar’s Odyssey is unmanned because it iscontrolled by NASA’s Mars ExplorationProgram. It is a long-term effort of roboticexploration of the red planet.
1. Themis (Thermal Emission Imaging System)-For determining the distribution of minerals, especially ones that can only form in the water.2. GRS (Gamma Ray Spectrometer)-It determines the presence of about 20 chemical elements on the planets surface.3. MARIE (Mars Radiation Environment Experiment)- studies radiation environment
Discovered subsurface water ice near poles Track changes of polar ice, clouds and dust storms Generated maps of radiation and minerals
Mars odyssey is: 2.2 meters long 1.7 meters tall 2.6 meters wide 1598 pounds including fuel and instruments
