Mars - 2003 Opposition


Object data: In August 2003 Mars made its closest approach to earth in nearly 60,000 years. In the above image Mars was captured a few days after closest approach, on 5th September 2003. The image was acquired at 23:18 GMT and is centered on the Tyrrhena region, with Cimmeria to the East, and Syrtis Major visible on the Western limb. The southern ice cap is about as small as it gets since this image was taken six days past perihelion during the southern summer.
