Craters in Memnonia Fossae, Mars
Mariner 4 image
showing craters in the Memnonia Fossae region of Mars. The large crater cut off through
the center at the right of the frame is the 156 km diameter Dejnev, centered at 25.6 S,
164.5 W. The image is 251 x 267 km and the upper left corner overlaps the lower right
corner of image 9. North is at 11:30. (Mariner 4, frame 10D)
Mariner crater on Mars
Mariner 4 image
of the crater named after it, the 151 km diameter Mariner crater at 35 S, 164 W. Running
from the lower left corner of the frame through the bottom of the crater is a linear ridge
which is part of Sirenum Fossae. The image was taken from 12,600 km and covers 250 km by
254 km. North is up. (Mariner 4, frame 11E)
South of Sirenum Fossae on Mars
Mariner 4 image
showing a relatively featureless area south of Sirenum Fossae on Mars. A few craters can
be seen in the image, which is centered at 35 S, 160 W. The picture was taken from a range
of 12,400 km and is 256 by 254 km. The upper left portion of this image overlaps the lower
right of image 11. North is up. (Mariner 4, frame 12D)
Light crater rims in the southern highlands of Mars
Mariner 4 image of the southern highlands south of Sirenum Fossae taken
during southern mid winter. The white rims of the craters may be due to frost or clouds,
but the contrast is poor. The rim at upper left may be the edge of the crater Newton. The
image was taken from 12,200 km and measures 254 km by 242 km. The sun is 58 degrees from
zenith and North is up. (Mariner 4, frame 13D)
Cratered highlands of Mars near 40 S, 150 W
Mariner 4 image from
12,200 km showing craters in the southern highlands of Mars. The image is 257 km across
and 240 km from top to bottom. The upper left corner overlaps with image 13. The sun is
shining from the northeast (upper left) 61 degrees from zenith, and north is up. (Mariner
4, frame 14B)
Surface of Mars 45 S, 144 W
Mariner 4 image
showing an area of the southern highlands at 46 S, 144 W. Light levels were getting low at
this point, so detail is difficult to pick out in the image and only indistinct features
can be seen. The image was taken from 12,000 km and the frame is 266 km by 236 km. The sun
was 67 degrees from zenith and north is at 12:30. (Mariner 4, frame 15E)
Surface of Mars near 48 S, 139 W, poor contrast
Mariner 4 image
of Mars near 48 S, 139 W. The lower light levels at this point necessitated high contrast
enhancements for this image, which gives it its grainy, layered appearance. Individual
features cannot be distinguished. The image was taken from 12,000 km and the frame is 273
x 236 km. The sun is 70 degrees from the zenith and north is at 12:30. (Mariner 4, frame
16D)
