Craters in southern Amazonis Planitia on Mars
This Mariner 4 image taken from 14,300 km shows some craters in southern
Amazonis Planitia. The image is 280 km across, 375 km from top to bottom and north is at
11:00. The sun is 19 degrees from vertical so some detail can be seen, but the shading is
still rather subdued. The image is centered at 2 S, 179 W. (Mariner 4, frame 05B)
Plains in southern Amazonis Planitia on Mars
Mariner 4 image showing a dark feature in the southern Amazonis Planitia. The part of this feature at upper left is also visible in the lower right of image 5. The image was taken from 14,100 km and the frame is 273 km across and 349 km vertically. North is at 11:00. (Mariner 4, frame 06E)
First picture clearly showing craters on Mars
With a
range of 13,600 km and a sun angle of 29 degrees from zenith, this Mariner 4 image was the
first picture showing unambiguous craters on the surface of Mars. The area, 262 x 310 km,
is a heavily cratered region south of Amazonis Planitia, centered at 14 S, 174 W. North is
at about 11:00. (Mariner 4, frame 07B)
Craters south of Amazonis Planitia
This image, the 8th taken by Mariner 4, confirmed the craters found in image 7. (Image 8 overlaps in its top left corner with the lower right of image 7.) The image was taken from 13,400 and covers 255 km by 296 km. The two craters at the center of the image are about 32 km in diameter. North is about 11:00. (Mariner 4, frame 08E)
Heavily cratered area in western Memnonia Fossae on Mars
Mariner 4 image showing at least twenty craters of various sizes on Mars,
resembling the lunar surface. The image was taken from 13,000 km and measures 253 by 225
km. The area is in western Memnonia Fossae, centered at 24 S, 169 W. The sun angle is 39
deg. from zenith, allowing some detail to be seen, including a central peak in the crater
right of the center. North is at 11:30. (Mariner 4, frame 09D)
