Moon Craters 3-D!

While many are hoping to see a larger-than-usual view of the Moon this weekend, here’s some great 3-D closeups courtesy of the Lunar Reconnaissance Orbiter and imaging wizard Nathanial Burton Bradford. This great 3-D view (Red/Cyan glasses needed) shows quite an interesting young impact crater on the Moon, (17.682°S, 144.408°E) west of Isaev crater. Click on the image for a larger view, and in 3-D you can dive right in and see all the nooks and crannies – what scientists call complex crater morphology.

Below you can view a Digital Terrain Model, or DTM of this same crater, and find the specifics of how deep the various parts of the crater are and other information critical to scientific investigations of the Moon.

Another recent view released by the LRO camera team is of impact melt deposit on another unnamed crater on nearside highlands (38.112°N, 53.052°E; northeast of Mare Tranquillitatis). Again, Nathanial Burton-Bradford provides a 3-D view, and amazingly, the crater walls appear deceptively steep in 3-D as opposed to the regular 2-D view:

What is impact melt? “So much energy is released when an asteroid or comet slams into the Moon that some of target rock (the Moon) is melted,” wrote Lillian Ostrach on the LRCO website. “For large craters, such as Tycho or Copernicus, the impact event responsible for forming these craters was large enough to generate melt that coated and covered the crater floor, and ejected melt pooled and flowed outside the crater cavity.”

Ostrach says that LROC images show that impact melt is widespread and quite common to lunar impact craters — but as this image shows – take a close look to find channels, flows, and veneers across much of the region.

Here’s LROC’s regular view:
