Firsoff (Martian crater)

Firsoff is an impact crater in the region called Meridiani Planum in the Oxia Palus quadrangle of Mars, located at 2.66°N latitude and 9.42°W longitude. It is 90 km in diameter. It was named after British astronomer Axel Firsoff, and the name was approved in 2010. There are mounds in the crater that may have formed from springs. They show breccia sometimes a pit at the top. Some of the mounds are lined up along straight fractures. The mound's composition and shape suggest water came out of the mounds and then minerals were precipitated.
