Odyssey over Mars' South Pole |
| Description |
NASA's Mars Odyssey spacecraft passes above Mars' south pole in this artist's concept illustration. The spacecraft has been orbiting Mars since October 24, 2001. NASA's Jet Propulsion Laboratory manages the Mars Odyssey mission for the NASA Office of Space Science, Washington, D.C. Investigators at Arizona State University in Tempe, the University of Arizona in Tucson, and NASA's Johnson Space Center, Houston, operate the science instruments. The gamma-ray spectrometer was provided by the University of Arizona in collaboration with the Russian Aviation and Space Agency and Institute for Space Research, which provided the high-energy neutron detector, and the Los Alamos National Laboratories, New Mexico, which provided the neutron spectrometer. Lockheed Martin Space Systems, Denver, is the prime contractor for the project, and developed and built the orbiter. Mission operations are conducted jointly from Lockheed Martin and from JPL, a division of the California Institute of Technology in Pasadena. |

Dr. Cary Zeitlin (not pictured), Principal Investigator for the Martian Radiation Environment ExperimentMARIE Instrument site [ http://marie.jsc.nasa.gov ] [ http://marie.jsc.nasa.gov ] Stephenie Lievense, Mars Outreach CoordinatorBiography [ http://mars.jpl.nasa.gov/odyssey/mission/profileLievense.html ]Mars Education [ http://mars.jpl.nasa.gov/classroom/index.html ] Participant Survey We would greatly appreciate your feedback. Please fill out a participant survey [ http://www.jpl.nasa.gov/surveys/mars/odyssey.php ]. More Information Since the 2001 Mars Odyssey orbiter arrived at Mars on October 23, 2001 we are learning what chemical elements (e.g., carbon, iron, etc.) and minerals are present at the planet's surface. Surprised scientists have found enormous quantities of buried treasure lying just under the surface of Mars -- enough water ice to fill Lake Michigan twice over. There are also tantalizing indications emerging from the thousands of infrared images already taken that Mars experienced a series of environmental changes during active geological periods in its history. Paving the way for future astronauts, Odyssey is also recording the Martian radiation environment to determine health risks for any future human explorers. During and after its science mission, the Odyssey orbiter will also support other missions in the Mars Exploration program. It will provide the communications relay for U.S. and international landers, including the next mission in NASA's Mars Program, the Mars Exploration Rovers, to be launched in 2003. Scientists and engineers will also use Odyssey data to identify potential landing sites for future Mars missions.

Comparison of Martian Radiation Environment with International Space Station |
| Description |
This graphic shows the radiation dose equivalent as measured by Odyssey's Martian radiation environment experiment at Mars and by instruments aboard the International Space Station, for the 11-month period from April 2002 through February 2003. The accumulated total in Mars orbit is about two and a half times larger than that aboard the Space Station. Averaged over this time period, about 10 percent of the dose equivalent at Mars is due to solar particles, although a 30 percent contribution from solar particles was seen in July 2002, when the sun was particularly active. NASA's Jet Propulsion Laboratory manages the 2001 Mars Odyssey mission for NASA's Office of Space Science, Washington, D.C. The radiation experiment was provided by the Johnson Space Center, Houston, Tex. Lockheed Martin Astronautics, Denver, Colo., is the prime contractor for the project, and developed and built the orbiter. Mission operations are conducted jointly from Lockheed Martin and from JPL, a division of the California Institute of Technology in Pasadena. Credit: NASA/JPL/JSC |

North polar water ice by weight December 8, 2003 |
| Description |
This map shows the percent of water by weight in near-surface materials of Mars' north polar region. It is derived from the gamma ray spectrometer component of the gamma ray spectrometer suite of instruments on NASA's Mars Odyssey spacecraft. Significant concentrations of water (greater than 20 percent) are poleward of 55 degrees north latitude. The highest concentration, greater than 50 percent, is between 75 degrees north and the pole. Another area with a high concentration of water by weight is in the north polar plains between longitudes minus 105 degrees and minus 140 degrees, and between latitudes 60 degrees and 75 degrees. NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the 2001 Mars Odyssey mission for the NASA Office of Space Science in Washington.

Radiation environment at Mars and Earth December 8, 2003 |
| Description |
This graphic shows the radiation dose equivalent as measured by Odyssey's martian radiation environment experiment at Mars and by instruments aboard the Earth-orbiting International Space Station (ISS), for the 18-month period from April 2002 through October 2003. The accumulated total in Mars orbit is just over two times larger than that aboard the Space Station. The bars where the Mars instrument's measurements are well above the average (as shown by the orange line) are months when there was significant solar activity, which increases the dose equivalent. Dose equivalent is expressed in units of milliSieverts per day. NASA's Jet Propulsion Laboratory manages the 2001 Mars Odyssey mission for NASA's Office of Space Science, Washington. The radiation experiment was provided by the Johnson Space Center, Houston, Texas. Lockheed Martin Space Systems, Denver, Colo., is the prime contractor for the project, and developed and built the orbiter.

Water mass map from neutron spectrometer December 8, 2003 |
| Description |
This map shows the estimated lower limit of the water content of the upper meter of Martian soil. The estimates are derived from the hydrogen abundance measured by the neutron spectrometer component of the gamma ray spectrometer suite on NASA's Mars Odyssey spacecraft. The highest water-mass fractions, exceeding 30 percent to well over 60 percent, are in the polar regions, beyond about 60 degrees latitude north or south. Farther from the poles, significant concentrations are in the area bound in longitude by minus 10 degrees to 50 degrees and in latitude by 30 degrees south to 40 degrees north, and in an area to the south and west of Olympus Mons (30 degrees to 0 degrees south latitude and minus 135 degrees to 110 degrees longitude). NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the 2001 Mars Odyssey mission for the NASA Office of Space Science in Washington. Investigators at Arizona State University in Tempe, the University of Arizona in Tucson and NASA's Johnson Space Center, Houston, operate the science instruments.
