Oxia Planum is a 200 km-wide clay-bearing plain located on the planet of Mars inside the Oxia Palus quadrangle on the eastern border of Chryse Planitia. The plain lies between the Mawrth Vallis outflow channel to the north-east and the Ares Vallis outflow channel to the south-west. In 2019, the International Astronomical Union Working Group for Planetary System Nomenclature officially approved Oxia Planum as a feature on the surface of Mars (near 18.275°N 335.368°E).[1][2]
Oxia Planum was one of eight potential landing sites for the European Space Agency and Roscosmos ExoMars mission. After a five-year-long selection process, it was officially selected to be the landing site for Rosalind Franklin (rover). It met the rover landing criteria based on its latitude, elevation,[3] surface slopes,[4] and its Noachian-aged terrains. It was chosen because of its relatively smooth topography and its abundance of hydrated minerals.[1][5][6]
