Kilometer-scale pyramidal structures found on Mars surface in Elysium Planitia and Cydonia. Photographs captured by the Mars Reconnaissance Orbiter Context Camera at approximately 5.8 meters per pixel resolution. HiRISE camera photographs are typically 1 GB in size, captured at 25 cm per pixel. A pyramid in Elysium Planitia has each side measuring approximately 3 km, with a flat top, a ramp/staircase on one side, and shows signs of water erosion and salt/sediment coverage at its base.
In Elysium Planitia, researchers found a pyramid with ~3 km sides—flat top, staircase ramp, and water erosion signs at its base. George Haas compared its ramp to Teotihuacan. A nearby three-ring formation mirrors Giza's layout (middle pyramid ~4 km). Near the Cydonia Face, a five-sided structure (~2.6 km/side) resembles the D&M Pyramid.
Key Facts
- Photographs captured by the Mars Reconnaissance Orbiter Context Camera at approximately 5.8 meters per pixel resolution.
- HiRISE camera photographs are typically 1 GB in size, captured at 25 cm per pixel.
- A pyramid in Elysium Planitia has each side measuring approximately 3 km, with a flat top, a ramp/staircase on one side, and shows signs of water erosion and salt/sediment coverage at its base.
- George Haas compared the Elysium Planitia pyramid to the pyramids at Teotihuacan based on ramp features.
- Three pyramidal rings were identified, with one slightly offset, mirroring the arrangement of the three Giza pyramids.
- The middle pyramid in the three-ring formation measures approximately 4 km in length.
- A five-sided pyramidal structure was found near the Face at Cydonia, similar to the D&M Pyramid, with two smaller sides forming a V-shape and two longer sides extending outward.
- The five-sided Cydonia pyramid measures approximately 2.6 km per side.
