text: There was many obstacles to find out who's face it was. "Twenty five years ago something funny happened around Mars. NASA's Viking 1 spacecraft was circling the planrt, snapping photos of possible landing sites for its sister ship Viking 2, when it spotted the shadowy likeness of a human face" (Unmasking the Face on Mars,1), This little bit of a paragraph tells us that basically someone was out just snapping pictures and found this. That's overly rare too have something like that happen.
