Before-and-After Look at Impact Craters Figure C

October 19, 2009
Figure C: The third figure shows before-and-after narrow-angle camera views of the impact site. The before image was acquired on Feb. 24, 2002. The after image was acquired on March 13, 2006.

Other images from Mars-orbiting spacecraft cover this location and show the impact site, including data from the Mars Express High Resolution Stereo Camera and Mars Odyssey Thermal Emission Imaging System. These other data help constrain when the impact occurred. The last orbiter image obtained before the impact was taken on April 18, 2003. The first orbiter image that showed the impact feature was obtained on Feb. 7, 2004. Thus, the impact occurred between those dates, April 18, 2003, and Feb. 7, 2004.
