Mariner 4 discovery image
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. Its name refers to the Mariner IV spacecraft. 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.
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).
