Isidis Planitia |
| Original Caption Released with Image |
24 December 2003 This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a small portion of the vast Isidis Planitia, the region in which the Beagle 2 [ http://beagle2.open.ac.uk ] is scheduled to land on 25 December 2003 (GMT, it will be the evening of 24 December 2003 in the U.S.). Much of Isidis Planitia has low hills and mounds like those shown here. Many of these are remnants of a layer (or group of sub-resolution layers) that once more extensively covered Isidis Planitia, but was later stripped away, revealing previously-buried meteor impact craters. The light-toned ridges and somewhat squiggly features are windblown dunes. This picture is located around 10.7°N, 268.6°W, which is in the vicinity of the projected Beagle 2 landing zone. The picture covers an area 3 km (1.9 mi) wide. Sunlight illuminates the scene from the left/lower left. |

| Original Caption Released with Image |
Released 24 December 2003 If all goes well, tonight at 6:54 pm PST the British robotic spacecraft called Beagle 2 [ http://beagle2.open.ac.uk/ ] will land on a patch of ground somewhere in this scene. This THEMIS image covers a portion of the Isidis Basin at the center of an elliptical region predicted to be the location that Beagle 2 will bounce to the surface. And what a surface it is, pockmarked by strange pits and unusual cones whose origin remains enigmatic. The cones may be the result of lava flowing over ice or water-rich ground resulting in explosions of steam that build small "rootless" volcanoes. The pits look like secondary craters that result from the impact of ejecta from larger craters. But they appear too numerous and densely clustered for that explanation. Instead, they also may be the result of some process involving water or ice. With luck, Beagle 2 will survive its violent landing and provide clues to the origin of this unusual landscape and answer questions about the role of water in Mars history. Image information: VIS instrument. Latitude 11.7, Longitude 90.4 East (269.6 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. 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. Lockheed Martin Astronautics, Denver, is the prime contractor for the Odyssey 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. |

Mars on 25 December 2003 |
| Original Caption Released with Image |
8 January 2004 This is how Mars appeared to the Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) wide angle system on 25 December 2003, the day that Beagle 2 and Mars Express reached the red planet. The large, dark region just left of center is Syrtis Major, a persistent low albedo terrain known to astronomers for nearly four centuries before the first spacecraft went to Mars. Immediately to the right (east) of Syrtis Major is the somewhat circular plain, Isidis Planitia. Beagle 2 arrived in Isidis Planitia only about 18 minutes before Mars Global Surveyor flew over the region and acquired a portion of this global view. Relative to other global images of Mars acquired by MGS over the past several martian years, the surface features were not as sharp and distinct on 25 December 2003 because of considerable haze kicked up by large dust storms in the western and southern hemispheres during th previous two weeks. The picture is a composite of several MGS MOC red and blue daily global images that have been map-projected and digitally wrapped to a sphere. Although the effect here is minor, inspection of this mosaic shows zones that appear smudged or blurry. The high dust opacity on 25 December impacted MOC's oblique viewing geometry toward the edges of each orbit's daily global mapping image, thus emphasizing the "blurry" zones between images acquired on successive orbits. |

18 Minutes After Beagle 2 Landing |
| Original Caption Released with Image |
31 December 2003 This oblique Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) wide angle red image shows the Beagle 2 landing zone about 18 minutes after the probe was scheduled to touch down on 25 December 2003. Mars Global Surveyor passed to the west of the site shortly after touch-down, so this image was taken looking east. The white ellipse shows the approximate location of the landing site. The largest crater to the northwest (toward upper left) of the ellipse is about 28 km (17.4 mi) across. The image is streaked and has low contrast because of the combined effects of looking obliquely and the presence of a thin veil of dust that not only hung over this region, but over most of Mars on 25 December 2003. During the previous 2 weeks, a large dust storm, followed by several smaller regional-scale storms, lifted dust in the western hemisphere of Mars. This dust drifted over most of the planet, reducing contrast and degrading the quality of MGS MOC images such as this one. This MOC image is important because it shows that there were no dust storms or other weather phenomena happening at the landing site the day Beagle 2 arrived. The landing site is located in Isidis Planitia near 11°N, 269.7°W. Sunlight illuminates the scene from the lower left. This and several other images processed by Malin Space Science Systems, Inc. were shown by the Beagle 2 team during a press conference on 29 December 2003.
