Apparently these photos were originally taken by Nasa a few decades ago and then scanned in by Professor Robinson of Arizona State, so I'm not sure if these artifacts are perhaps due to the storage methods used or something, or if these are actually in the original photo. There are a ton of them though. Any thoughts? SRC) http://wms.lroc.asu.edu/apollo/browse http://apollo.sese.asu.edu/data/pancam/AS16/png/AS16-P-4111_FULL_LRG.png
