The two above photos are the same, I added color to allow you to see the building. Location of discovery: MercuryNASA Mission: Mariner 10Photo ID: PIA00068Exact Location on Mercury: Tolstoj Quadrangle H-8NASA Photo: http://photojournal.jpl.nasa.gov/jpeg/PIA00068.jpgThis is the 3rd photo that I found structures in on Mercury. This photo is not a black and white photo, but an infrared photo. The Mariner 10 had an "8-postition filter wheel." Each filter allows the camera to take a different kind of photo.
