Ejriksson Crater is an impact crater in the Memnonia quadrangle of Mars, located at 19.4°S latitude and 173.9°W longitude, and is in the north of Terra Sirenum. It is 49.0 km in diameter and was named after the explorer Leif Ericson, and the name was approved in 1967,[1] alongside Mariner and Nansen being the first named craters on Mars and also the solar system outside the Earth and the Moon. The first close-up detail of Ejriksson crater and area was first pictured by the Mariner 4 spacecraft in 1964 and was the eighth image taken.
Image taken by Mariner 4 in 1965 being the eighth photo of Mars taken by an orbiter. Ejriksson is below the middle portion with a wide black streak
Other major craters include Williams to the east and Dejnev to the east-southeast, further west-northwest is Gusev located in the Aeolis quadrangle. Under 300 km west is the 180th meridian marking the furthermost portion of Mars, west of the meridian is the long Ma'adim Vallis. Further north is Lucus Planum, an area containing a few but small craters.
