The Beagle 2 lander reached Mars on 25 December 2003, but no communication with the lander has occurred since that time (as of this writing). Following the spacecraft's arrival in Isidis Planitia near 11.7°N, 269.6°W, the final landing ellipse size and location were better refined. As it turns out, there were no Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) high resolution images of the final ellipse. The very first opportunity to acquire a MOC image of the ellipse after the Beagle 2 arrival occurred on 5 January 2004.

The 5 January 2004 opportunity did not come without issues, however. One problem---the atmosphere of Mars became quite dusty in middle and late December 2003. Increased dust opacity degrades the quality of MOC high resolution images. The second problem---shortly after the Mars Exploration Rover (MER-A) Spirit landing on 4 January 2004, Mars Global Surveyor fired its rockets to begin the process of moving into position for the 25 January 2004 MER-B (Opportunity) landing. The MOC image of the Beagle 2 site had to be commanded and uplinked to MGS before the results of this burn were known. In other words, if the burn did not go according to plan, the image might not hit the Beagle 2 landing ellipse.

In the end, the MGS burn went as planned and the MOC image of the Beagle 2 landing ellipse was obtained, on schedule, on 5 January 2004. The picture at the left, above, is a map-projected view of the 5 January 2004 high resolution image. It was acquired with a resolution of about 1.5 m/pixel, and is available here at projected scales of 1, 3, and 5 m/pixel. As expected, the high resolution image is somewhat noisy and hazy because of dust suspended high in the atmosphere. There is no obvious sign of the lander in this image, which only covers a fraction of the area in which Beagle 2 might have landed. The map on the right, above, shows the final Beagle 2 landing ellipse with the location of the new MOC image placed within this context. The map is a mosaic of Mars Odyssey Thermal Emission Imaging System (THEMIS) visible and daytime infrared images. THEMIS is operated at Arizona State University; the map was produced at Malin Space Science Systems to provide context for the Beagle 2 landing site. In both the MOC picture and the landing ellipse mosaic, sunlight illuminates the images from the left. For scale, the MOC image is about 3 km (1.9 mi) wide. North is up.

Tips for Media Use


Malin Space Science Systems and the California Institute of Technology built the MOC using spare hardware from the Mars Observer mission. MSSS operates the camera from its facilities in San Diego, California. The Jet Propulsion Laboratory's Mars Surveyor Operations Project operates the Mars Global Surveyor spacecraft with its industrial partner, Lockheed Martin Astronautics, from facilities in Pasadena, California and Denver, Colorado.
