Today's Image of Mars is suited especially for Valentines Day! It shows a heart-shaped pit formed by a collapse within a graben. The pit imaged is about 2.3km at its widest point.
This image was taken by the Mars Global Surveyor's Mars Orbiter Camera in 1999, but it still can be used to show how much you heart your space loving Valentine!
