Box 284, Glenn Dale, MD 20769 Abstract-Evidence suggesting a past humanoid civilization has been found at several sites on Mars. In particular, what appear to be large carved faces, with similar details, have been found at two separate sites. Together with geochemical and geological evidence that suggests Mars was once more Earth-like in climate, the images of the objects support the Cydonian Hy- pothesis: That Mars once lived as the Earth now lives, and that it was once the home of an indigenous humanoid intelligence. Introduction Mars is a planet whose past is a mystery, but like all great mysteries, the keys to solving the puzzle may hide in plain sight. Mars, with its somber red surface, its vast and winding canyon systems displaying deep deposits of sedimentary rock, its great scablands telling of past awesome floods ofwater, and its windswept plains cratered like the Moon, is a planet that appears to tell two conflicting stories. One, of a small planet that was struggling for a long, indefinite period to have a climate like Earth; and another, of a planet battered by asteroids that lost all but a thin atmosphere early in its history and has been barren and Moon-like ever since. It has been found that in the middle of this planetscape of past desolation and destruction, there appears to be a carved humanoid face. What do all of these clues mean? In particular, is the face a spurious occurrence, irrelevant to solving the puzzle of Mars' past, or is it perhaps the key piece? After many years of studying the whole array of data concerning Mars, we have decided to advance the hypothesis that the Face on Mars is in fact the "Rosetta stone," the key piece of evidence for understanding Mars' past climate. This hypothesis is termed the Cydonian Hypothesis since it hypoth- esizes that the face is in fact an image of a Cydonian, an extinct humanoid race indigenous to Mars who, before they perished, carved the face and created other objects found in Viking images. The Cydonian Hypothesis The hypothesis, that Mars, the home of a long-lived biosphere similar in scope and diversity to that of Earth, and that out of this biosphere evolved an indigenous humanoid race, termed Cydonians, that constructed large mon- 2 J.

The As- sumption that neither the Earth nor its biosphere nor its humanoid deni- zens nor the civilization and artifacts they have produced are unique or even remarkable in the Cosmos. By this assumption, the discovery of a dead civilization on an Earth-like planet such as Mars would not be surprising. 2. Images of the surface of Mars showing, at several sites what appear to be three carved humanoid Faces (Brandenburg & DiPietro, 1986), of kilo- meter scale, and having similar anatomical and ornamental details be- tween all three. Appearing with these objects are numerous other objects and surface features that resemble Earth-like archaeological ruins, of a Bronze Age culture, with no evidence of advanced technology or civil- ization. 3. Geological and geochemical data that are consistent with past condi- tions on Mars that were favorable to Earth-like life forms: Abundant liquid water (Masursky, Boyce, Dial, Selaber, & Strobell, 1977), and an atmosphere that was dense and warm, and possibly rich in oxygen (Toul- min I11 et al., 1977). Modern Searches For Civilizations On Mars Because of its close proximity and similarity to Earth, Mars has always been the subject of speculation about its capacity to support life and intelli- gence. Sagan and Fox (1 975; Sagan & Wallace, 197 1) examined the first high-resolution photographs of the Martian surface acquired by Mariner 9 for signs of a civilization of our technological level and extent. They were guided in this search by images of Earth at similar resolution (Sagan & Wal- lace, 197 l). These pictures of Earth showed human civilization clearly. How- ever, in the images of Mars, no signs of a civilization of our technological level and extent were found. Furthermore, in the Mariner 9 images, no objects that were strongly suggesting civilization of any known type were found. Other investigators reported objects resembling ancient pyramids of large size (Figure 1) in Elysium Planitia. When the Viking probes obtained high-resolution pictures of Mars in 1976, however, an object was found by Dr. Tobias Owen which resembles a mammoth carved head; this object was dubbed the "Face of Mars" (Soffen, 1980), (Figure 2). Two of the authors (DiPietro and Molenaar) studied the original image from the Viking frame 35A72 and discovered a second image on frame 70A 13. They enhanced the images using digital methods and copies of the raw data tapes, which were supplied by the Jet Propulsion Laboratory in Pasadena, California. The results of their investigations were published at a Mars science conference (Oberg, 1983) and in a series of pamphlets (DiPie- tro & Molenaar, 19 80; DiPietro, Molenaar, & Brandenburg, 19 88).

Faces and other strange objects at other sites on Mars were found (Figure 3),and their similar- ity of sire and detail to the Face of Mars was discovered and presented at a scientific conkrence (Brandenburg & DiPielro, 1986). Finally, other investi- gators have studied the Cydonia site and published work concerning it (Car- lotto, 1988; Carlotto & Stein, 1990; O'l,eary, 1990).

'The Cydonia Mensa region of Mars is marked by a range of small mountains and mesas that runs Norlh at approximately the low plain-highlands boundary, and then makes an abrupt nght turn out into Acidalia Planitla (Figure 4). The Cydonia Mensa has been extensively photo mapped (Frey & l,owry, 1979; Guest, Buttenvo~h,& Creely, 1977) and shows signs of ab~indantwater in the past. The site of interest lies Just above the Zero Kilometer elevation line of Mars (Bahson, Bridges, & Inge, 1979). At the corner of the range of nlesas, at 9 degrees W, 41 degrees N lies the object known as the "Face of Mars." ""The Face of Mars" here referred to as "the Face in Cydonia," or simply the ""Face" appears in the Viking frame 35A72 taken at a range of 1,873 km, and 70A 13 taken at a range of 1724 km. Both of these frames were taken during the course of photo mapping in the Cydonia region in the afternoon. DiPietro and Molenaar used digital tech- niques to enhance the images, and used a version of bilinear interpolation, which they developed and call the Starburst Pixel Interleaving Technique (SPIT) process, to enlarge and smooth the images, A thorough discussion of I lg 4.

Further enhancement of the images was done by Dr. Mark Carlotto of The Analytic Sciences Corporation (TASC) in Reading, Massachusetts (Carlotto, 1988), using a technique that be has developed. His images appear to show teeth in the mouth area of the Face (Figure 5). Mark Carlotto and Brian O'Leary have also published further analyses of tkFace (Carlotto & Stein, 1990; O'Leary, 1990). - - - - This pamphlet is available for $15 by writing to: Mars Research, P.C>.Box 284, Cilenn Dale, MD 20769.
