Face on Mars Cydonia

Face on Mars Cydonia

Summary

Headline Finding:

The "Face on Mars" in Cydonia is an optical illusion caused by pareidolia, where natural geological formations resembling a human face were captured under specific lighting conditions by NASA's Viking 1 orbiter in 1976. Higher-resolution images from subsequent missions like the Mars Global Surveyor and Mars Express have confirmed its natural origin.

Key Findings:

  • The "Face on Mars" is a two-kilometer-long mesa located in Cydonia, imaged for the first time by Viking 1 orbiter on July 25, 1976, under low sunlight angles that created shadows resembling facial features [1][2].
  • Higher-resolution images from the Mars Global Surveyor (MGS) and Mars Express revealed it to be an ordinary Martian hill, confirming pareidolia as the cause of its face-like appearance [1][2][4][5].
  • Despite scientific consensus, some individuals like Richard C. Hoagland have argued that the formation is evidence of a long-lost Martian civilization, but these claims are not supported by mainstream science [1][3][7].
  • The Cydonia region includes other geological features such as mesas (Cydonia Mensae) and hills (Cydonia Colles), which have also been subject to pareidolia [6].

Disagreements:

  • While the scientific community attributes the "Face on Mars" to natural geological processes, some researchers like Richard Hoagland continue to argue for its artificial origin based on perceived geometric precision and alignment [3][7].

Open Questions:

  • What specific geological processes led to the formation of the mesa in Cydonia that resembles a face?
  • Are there any ongoing studies or missions planned to further investigate the geological features of the Cydonia region beyond confirming their natural origins?

  • The "Face on Mars" is an optical illusion: It appears as a two-kilometer-long mesa in Cydonia, Mars, and was first imaged by Viking 1 orbiter in 1976.
  • Cydonia's location: This region lies in the northern hemisphere of Mars, bordering Acidalia Planitia plains and Arabia Terra highlands. It is believed to have once been a coastal zone if the northern plains were ocean beds.
  • Viking images: The "Face on Mars" was captured by Viking 1 orbiter on July 25, 1976, in image 035A72 and again with different lighting conditions in image 070A13. These images had a resolution of about 50 m/pixel.
  • Later observations: Higher-resolution images from Mars Global Surveyor (MGS) and Mars Express revealed the "face" to be an ordinary Martian hill, confirming it as pareidolia—a psychological phenomenon where random patterns are perceived as significant shapes.
  • Speculation and skepticism: Despite scientific consensus, some individuals like Richard C. Hoagland have argued that the face is evidence of a long-lost Martian civilization along with other features resembling pyramids. Carl Sagan criticized these claims in his book "The Demon-Haunted World."
  • Similar optical illusions on Earth: Examples include the Old Man of the Mountain and Giewont, highlighting how pareidolia can occur naturally.
  • Skepticism and ridicule: Skeptics often use the "Face on Mars" as an example of credulity, pointing out other face-like formations on Mars that do not receive similar attention.

  • The Mars Reconnaissance Orbiter (MRO) captured new high-resolution images of the "Face on Mars" mesa in 2023, confirming it is not a face but a natural formation.
  • Compared to the previous image taken in 2007, the new photos have better lighting conditions and reveal more details on the eastern half of the mesa.
  • The new images suggest that there may be a decaying glacier in the depression on the mesa’s eastern slopes due to its location within mid-latitudes known for near-surface ice features.
  • Scientists took two pictures (on October 1, 2023 and November 4, 2023) to create a stereoscopic view, which will help identify any changes since 2007.

Additional Notes:

  • The "Face on Mars" was initially identified as a mesa resembling a face in low-resolution imagery.
  • The northern lowland plains near the mesa have many ice features, suggesting the possibility of an ice sheet at its base.

NASA orbiter captures image of a bear's face on Mars

<https://www.accuweather.com/en/space-news/nasa-orbiter-captures-image-of-a-bears-face-on-mars/1476316>

  • A NASA orbiter captured an image of what appears to be a bear's face on Mars through its High Resolution Imaging Science Experiment (HiRISE) camera in December.
  • The "bear face" is formed by geological features: a circular fracture pattern for the head, two craters as eyes, and a V-shaped collapse structure resembling a nose.
  • Scientists suggest that the circular fracture could be due to settling of deposits over a buried impact crater filled with lava or mud. The nose-like feature might be a volcanic vent or a mud vent.
  • This image is similar to other instances where natural formations on Mars have resembled familiar shapes, such as a rock formation resembling a flower spotted by Curiosity rover in March 2023 and the "face" seen on the sun due to coronal holes in October 2022.
  • The HiRISE camera has been operational since 2006, capturing detailed images of Martian features down to 3 feet (1 meter) in size.
