Johnson (center right) in July 1965. This was the discovery image of Mariner crater, and is named for the Mariner 4 spacecraft.^[1]

Mariner Crater is a crater on Mars with a diameter of 170 km. it is located in the Phaethontis quadrangle at 35.1° south latitude and 164.5° west longitude. Mariner were its first three named craters on Mars alongside Ejriksson and Nansen that were officially named by the IAU in 1967,^[2] and being the Solar System's first named craters outside the Earth and the Moon. It was named for Mariner IV spacecraft.^[2] In fact it is probably the best image that was taken with the Mariner IV spacecraft. Images of this crater are shown from the Mariner 4 and Mars Reconnaissance missions. One can compare the resolutions from the Mariner IV camera, CTX, and HiRISE.

Nearby geographical features includes the larger Newton to the southeast, the smaller Magelhaens to the west-northwest and Cross nearly to the northeast.. Southwest is Gorgonum Chaos. The southernmost part of the crater and most of its southern rim is crossed by Sirenum Fossae, a 2,735 km long trough.

Gullies are found in Mariner.^[3][4]

  This topographic map shows volcanic peaks in white because of their great height. Near the equator, a line of three volcanoes points south to Phaethontis and three large craters-the area where there are many gullies. Click on the image for a good view.

  Mariner Crater, as seen by Mariner 4. This is probably the best picture that our first spacecraft to fly by Mars took. Image located in Phaethontis quadrangle.

  Section of Mariner Crater that was imaged by the Mariner 4 space craft. The crater on the floor of the much larger Mariner Crater is the smaller of the two craters on the floor. Straight troughs in the south are visible in this image and in the Mariner photo. This image was taken with CTX camera (on Mars Reconnaissance Orbiter).
