An image of what clearly appears to be an impact furrow and an associated actual crashed UFO-like disc-shaped object has been discovered in a Mars Reconnaisance Orbiter photograph, https://www.theblackvault.com/casefiles/...-46-AM.jpg . An article discussing this is at https://www.theblackvault.com/casefiles/...mber-2006/ . This doesn't seem to be like one of the vaguely man-made object images previously offered - this one at least looks definite. The article writer even includes the ZIP file of the original high-resolution image. What does NASA say? Could this be a hoax?
