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.

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. 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, 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 further zoom emphasizes a small, fresh crater about 350 meters (1,150 feet) in diameter near the center of the scene. The adjacent cliff contains numerous individual layers. An unusual set of small mesas, seen in the lower right part of the image, is being eroded from the polar layered material. The images making up this mosaic have a spatial resolution of 36 meters (118 feet) per pixel, allowing detection of features as small as 75 to 100 meters (246 to 328 feet) across.

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).

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.

Ridges |
| Original Caption Released with Image |
Released 11 April 2003 Tall narrow ridges snake between mesas and buttes. Where one such ridge crosses a flat-topped mesa (in the lower center of the image), the mesa surface is split into two surfaces of different heights, like a split-level house. This suggests that the ridges, like the mesas and buttes, are erosional remnants of a former surface that has since been mostly stripped away. Note: this THEMIS visual image has not been radiometrically nor geometrically calibrated for this preliminary release. An empirical correction has been performed to remove instrumental effects. A linear shift has been applied in the cross-track and down-track direction to approximate spacecraft and planetary motion. Fully calibrated and geometrically projected images will be released through the Planetary Data System in accordance with Project policies at a later time.

Layers and Erosion and more Layers |
| Original Caption Released with Image |
Released 4 November 2003 This image is located within a set of eroded layered rocks known as the Medusae Fossae Formation. Careful inspection of this image reveals four separate layers. Starting at the bottom of the image, as well as the bottom of the sequence of layers, is a somewhat hilly, cratered plain. Above that is a mud or lava flow with a lobate edge that is characteristic of fluid flow. Above that is a layer with a spectacular rayed crater. This layer shows linear erosional patterns that are probably caused by persistent wind abrasion, typical of rocks in this area. And finally, a more blocky unit lies on top, mostly eroded away. Image information: VIS instrument. Latitude 3.6, Longitude 218.6 East (141.4 West). 19 meter/pixel resolution. Note: this THEMIS visual image has not been radiometrically nor geometrically calibrated for this preliminary release. An empirical correction has been performed to remove instrumental effects.

Sand and Water |
| Original Caption Released with Image |
Released 7 November 2003 This image shows a relatively small crater (~35 km across) in the heavily cratered terrain of the southern highlands. At the midlatitudes, this area is known both for its water-formed gullies and its sand dunes. This crater shows spectacular examples of both. In fact, the gullies running down the northern edge of the crater made it to the cover of Science magazine on June 30, 2000. The large dark spot in the floor of the crater is sand that has accumulated into one large dune with a single curvilinear crest. Image information: VIS instrument. Latitude -54.9, Longitude 17.5 East (342.5 West). 19 meter/pixel resolution. Note: this THEMIS visual image has not been radiometrically nor geometrically calibrated for this preliminary release. An empirical correction has been performed to remove instrumental effects. A linear shift has been applied in the cross-track and down-track direction to approximate spacecraft and planetary motion.

Cerberus Fossae Fractures |
| Original Caption Released with Image |
Released 29 October 2003 The fractured surface of the Cerberus region southeast of the Elysium volcanoes provides an impressive example of the powerful tectonic forces that have shaped the region. Both the smooth lava plains and the mountains that poke through the lava are subject to the extensional forces that rip open the landscape. The fractures are radial to the Elysium complex, suggesting a relationship to the volcanic processes that have built it. Image information: VIS instrument. Latitude 8.6, Longitude 160.6 East (199.4 West). 19 meter/pixel resolution. Note: this THEMIS visual image has not been radiometrically nor geometrically calibrated for this preliminary release. An empirical correction has been performed to remove instrumental effects. A linear shift has been applied in the cross-track and down-track direction to approximate spacecraft and planetary motion.
