Fresh Crater in Arabia Terra Figure B

Figure B: This set of images shows how the impact site appeared to the Mars Odyssey Thermal Emission Imaging System infrared instrument before and after the impact. The white circle indicates the location of the impact site. Both images are from the Thermal Emission Imaging System band 9 (approximately 12.6 micrometers wavelength); the first image was obtained on June 30, 2002, the second on Oct. 5, 2003. In the 2003 image, the impact site appears as a bright spot, because it was warmer than the surroundings at the time the data were acquired.
