NASA imaging produces incredibly detailed image of moon crater
Check out the above image of Aristarchus, a crater on the moon that can be seen with the naked eye back on Earth. Spot a boulder you want to check out? Well, feel free to zoom in, because the NASA Lunar Reconnaissance Orbiter has imaged the crater to a resolution of 15 inches. The crater is twice as deep as the Grand Canyon and 26 miles wide, and showcases a host of interesting geological features, including glassy ash from the asteroid impact which caused the crater, and sagging pre-impact lunar crust. The image shows a 2 mile portion of the crater wall, and was snapped by the orbiter at a height of just 16 miles - only twice the altitude of a commercial jet.
