This triangle UFO was caught by the rover this week in photo Sol 688. I say triangle, because it looks like a TR3B from a distance. The ball in its center and its shorter end...says that it could be a triangle with two points showing. This UFO was discovered by Youtube user Streetcap1, famous for his discoveries in NASA photos. He says, "Nearly spilt my coffee when I saw this."
