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. 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 ### |

MSIP: Hale Crater |
| Original Caption Released with Image |
Released 29 April 2004 This image was taken by the Mercury Mine 5th grade MSIP team in order to answer the question -- Is there water erosion on crater walls? It is located at Hale Crater, lat. 33.1S and long. 324.4E. It shows a crater wall with smaller craters and groves. This MSIP team consists of 22 5th graders at Mercury Mine Elementary in the Paradise Valley school district. Our instructor is Mr. Collins. We started the program in early October 2003 and went to ASU in March of 2004. All in all we had a GREAT time! Image information: VIS instrument. Latitude -33.7, Longitude 324.4 East (35.6 West). 19 meter/pixel resolution. NASA and Arizona State University?s Mars Education Program is offering students nationwide the opportunity to be involved in authentic Mars research by participating in the Mars Student Imaging Project (MSIP). Teams of students in grades 5 through college sophomore level have the opportunity to work with scientists, mission planners and educators on the THEMIS team at ASU?s Mars Space Flight Facility, to image a site on Mars using the THEMIS visible wavelength camera. For more information go to the MSIP website: http://msip.asu.edu [ http://msip.asu.edu ]. 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. NASA's Jet Propulsion Laboratory manages the 2001 Mars Odyssey mission for NASA's Office of Space Science, Washington, D.C. The Thermal Emission Imaging System (THEMIS) was developed by Arizona State University, Tempe, in collaboration with Raytheon Santa Barbara Remote Sensing. The THEMIS investigation is led by Dr. Philip Christensen at Arizona State University.

| Title |
Mars in Color |
| Original Caption Released with Image |
Released 3 October 2003 An enhanced color image from the eastern edge of Acidalia Planitia shows a heavily eroded landscape just south of the outflow channel called Mawrth Vallis. The THEMIS VIS camera is capable of capturing color images of the martian surface using its five different color filters. In this mode of operation, the spatial resolution and coverage of the image must be reduced to accommodate the additional data volume produced from the use of multiple filters. To make a color image, three of the five filter images (each in grayscale) are selected. Each is contrast enhanced and then converted to a red, green, or blue intensity image. These three images are then combined to produce a full color, single image. Because the THEMIS color filters don't span the full range of colors seen by the human eye, a color THEMIS image does not represent "true color." Also, because each single-filter image is contrast enhanced before inclusion in the three-color image, the apparent color variation of the scene is exaggerated. Nevertheless, the color variation that does appear is representative of some change in color, however subtle, in the actual scene. Note that the long edges of THEMIS color images typically contain color artifacts that do not represent surface variation. Image information: VIS instrument. Latitude 24.5, Longitude 338.4 East (21.6 West). 38 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.

The Summit of Olympus Mons |
| Original Caption Released with Image |
Released 9 October 2003 Bold scarps and extensional features (grabens) record multiple stages of caldera collapse at the summit of Olympus Mons. The wrinkle ridges are contractional features, and probably formed during the cooling of an ancient lava lake, prior to the collapse events. Olympus Mons is the largest volcano in our solar system, reaching heights of over 40 km tall from base to summit, with the base covering an area as large as the state of Arizona.

Craters Modified by Ice |
| Original Caption Released with Image |
Released 2 October 2003 These craters, located in the southern highland heavily cratered terrain, show heavy degradation, most likely caused by the presence of water ice. A smaller crater is located in the floor of a larger crater, showing lobate ejecta thought to be created by water melted by the force of the impacting body. Gullies on the northern rim of the smaller crater may indicate accumulations of snow and subsequent melting. In the larger crater, the northern rim is greatly softened, with sinuous features suggestive of downslope flow, also potentially caused by creep of ground ice. Image information: VIS instrument. Latitude -40.4, Longitude 132.5 East (227.5 West). 38 meter/pixel resolution. Note: this THEMIS visual image has not been radiometrically nor geometrically calibrated for this preliminary release.

| Title |
Two Craters |
| Original Caption Released with Image |
Released 6 October 2003 Two craters east of the Hellas impact basin dominate the field of view of this THEMIS visible image. The craters are alike in that they have been filled in by a lot of material after they were formed. There is an important difference between them, though. The northern crater in the image has a relatively smooth, flat bottom, and the infilling material looks as if it hasn't been heavily disturbed since it was emplaced. Contrast this with the interior of the second crater. The infilling material has been heavily eroded. Why did these two craters, which are so close together, experience very different erosional histories? This THEMIS image is a great example of how science data sets can sometimes cause more questions than they answer. Image information: VIS instrument. Latitude -31, Longitude 107.1 East (252.9 West). 19 meter/pixel resolution. Note: this THEMIS visual image has not been radiometrically nor geometrically calibrated for this preliminary release.
