Explanation: Still bright in evening skies, Mars was just past opposition [6]
and closest to Earth on July 31, a mere 57.6 million kilometers away. Captured
only a week later, this remarkable image shows the Red Planet's disk [7] near
its maximum size in earthbound telescopes, but still less than 1/74th the
apparent diameter of a Full Moon. Broad regional surface shadings are starting
to reappear in the tantalizing [8] view as the latest planet-wide dust storm
subsides [9] . With the bright south polar cap at the bottom, the Valles
Marineris extends along the center of the disk. Just below it lies [10]  the
roughly circular Solis Lacus region sometimes known as the Eye of Mars [11] .
In a line, three prominent dark spots left of center are the volcanic Tharsis
Montes.
