Viking 1 Orbiter Images
Yuty crater in Chryse Planitia, Mars
Viking 1 Orbiter view of Yuty crater on Mars. The 18
km diameter crater is surrounded by complex ejecta lobes, one of which partly covers an
older crater. North is at about ~1:00. (Viking Orbiter 003A07) Belz Crater, Chryse Planitia, Mars
This Viking 1 Orbiter image shows Belz Crater in Chryse
Planitia, Mars. Belz is a typical rampart crater, showing a raised ridge or rampart around
the inner ejecta layer. These ramparts may be the result of ejecta being emplaced as a
debris flow rather than ballistically as is the case for craters on the Moon. North is at
~1:30 in this image. The frame is about 50 km wide. (Viking Orbiter 010A56)
Flow around Dromore Crater, Chryse Planitia, Mars
Viking 1 Orbiter image of Dromore Crater in Chryse Planitia,
Mars. Flow from the left (west) appears to have broken through low points on the ridge and
eroded the channels as it flowed around the 15 km diameter crater. The image is
approximately 50 km across. North is at about 1:30. (Viking Orbiter 020A62)
Crater near Kasei Vallis, Mars
An image of a crater with a dramatic
radial ejecta pattern near the edge of Kasei Vallis, Mars, taken by the Viking 1 Orbiter.
The crater is 18 km in diameter. North is at ~1:00. (Viking Orbiter 22A54)
Mars northern lowland fractured terrain
Viking 1 Orbiter image showing patterned ground in the
northern lowland plains of Mars. The individual polygons bounded by the fractures can be
up to 20 km across, much larger than the 100 m sizes found in the nearest terrestrial
analogue, ice wedging in periglacial regions. The image is 85 km across and north is at
~1:30. (Viking Orbiter 32A18)
Fractured northern plains, Mars
This Viking 1 Orbiter image shows a pattern of
fractures commonly found in the northern plains of Mars. These polygons are approximately
5 to 10 km across, and are similar in appearance to certain terrestrial processes, but on
a much larger scale. Note that the fracture crevasses are fairly wide with flat floors.
North is at ~11:00 in this image, which is about 50 km wide. (Viking Orbiter 035A64)
