Smile and Say “Olympus Mons”!
NASA does churn out some fairly interesting snapshots from their Mars missions, and this is no exception. The Mars Orbiter Camera onboard the Mars Global Surveyor snapped a picture of the Mars Odyssey as it went zipping by in orbit. Because the camera acquires images line by line, it actually appears twice in a single frame. Each image is about 7.5 seconds and 31 miles apart.
