Candor Chasma is one of the largest canyons in the Valles Marineris canyon system. It is located at 6.6 S and 70.9° W (289.1 E) in the Coprates quadrangle. Mars Reconnaissance Orbiter discovered sulfates, hydrated sulfates, and iron oxides in Candor Chasma.[1] Hence, water has been present in the past to form some of these minerals.


Origin of Name

Coprates is the name of a classical albedo features on Mars. It is named after the Coprates River, an ancient name for the Dez River in modern Iran which empties into the Shatt al-Arab near its Persian Gulf estuary. The name was approved by the International Astronomical Union (IAU) in 1958.[2][3]


Chandor Chasma was made famous in the novel "Red Mars" by Kim Stanley Robinson as the location of the first future Mars base after the first manned mission in 2026. The idea of "Underhill", the first established settlement, originates from the Hillside settlement as designed by the Mars Foundation's co-founder, Bruce Mackenzie.
