Heart-Shaped Feature

Post  Admin on Sun Nov 27, 2011 2:47 am



This picture of a heart-shaped feature in Arabia Terra was taken on 23 May 2010 by the CTX camera on the MRO spacecraft. A small impact crater near the tip of the heart is responsible for the formation of the bright, heart-shaped feature. When the impact occurred, darker material on the surface was blown away, and brighter material beneath it was revealed. Some of this brighter material appears to have flowed further downslope to form the heart shape, as the small impact occurred on the ejecta blanket of a much larger impact crater. The heart-shaped feature is about 1 km long and is centered at 21.9°N, 12.7°W. This feature is visible in a much lower resolution Viking 1 image acquired in January 1977.

Another Heart Shaped Feature on Mars





This picture of a heart-shaped pit was taken on 26 February 2008 by the CTX camera aboard MRO. It is approximately 2 km long and is centered at 3.7° N, 29.9° W. The pit is one of many adjacent to Hydaspis Chaos, a jumbled topographic depression thought to have formed by collapse of the surface due to—perhaps—catastrophic release of groundwater.
