Image of the Phaethontis Quadrangle (MC-24). The region is dominated by heavily cratered highlands and low-lying areas forming relatively smooth plains.

The Phaethontis quadrangle is one of a series of 30 quadrangle maps of Mars used by the United States Geological Survey (USGS) Astrogeology Research Program. The Phaethontis quadrangle is also referred to as MC-24 (Mars Chart-24).[1]

The name comes from Phaethon, the son of Helios.[2]

The Phaethontis quadrangle lies between 30° and 65° south latitude and 120° and 180° west longitude on Mars. This latitude range is where numerous gullies have been discovered. An old feature in this area, called Terra Sirenum lies in this quadrangle; Mars Reconnaissance Orbiter discovered iron/magnesium smectites there.[3] Part of this quadrangle contains what is called the Electris deposits, a deposit that is 100–200 metres (330–660 ft) thick. It is light-toned and appears to be weak because of few boulders.[4] Among a group of large craters is Mariner Crater, first observed by the Mariner 4 spacecraft in the summer of 1965. It was named after that spacecraft.[5][page needed] A low area in Terra Sirenum is believed to have once held a lake that eventually drained through Ma'adim Vallis.[6][7][8][page needed] Russia's Mars 3 probe landed in the Phaethontis quadrangle at 44.9° S and 160.1° W in December 1971. It landed at a speed of 75 km per hour, but survived to radio back 20 seconds of signal, then it went dead. Its message just appeared as a blank screen.[9][page needed]
