Tempe Fossae [SEP] located on astronomical body
Tempe Fossae
The Tempe Fossae are a group of troughs in the Arcadia quadrangle of Mars, located at 40.2° north latitude and 71.4° west longitude. They are about 2,000 km long and were named after an albedo feature at 40N, 70W. 
The term "fossae" is used to indicate large troughs when using geographical terminology related to Mars. Troughs, sometimes also called grabens, form when the crust is stretched until it breaks, which forms two breaks with a middle section moving down, leaving steep cliffs along
Fossa (planetary nomenclature)
In planetary nomenclature, a fossa (pl. "fossae") is a long, narrow depression (trough) on the surface of an extraterrestrial body, such as a planet or moon. The term, which means "ditch" or "trench" in Latin, is not a geological term as such but a descriptor term used by the United States Geological Survey (USGS) and the International Astronomical Union (IAU) for topographic features whose geology or geomorphology is uncertain due to lack of
