The Mars 2 and 3 orbiters sent back a relatively large volume of data covering the period from December 1971 to March 1972, although transmissions continued through to August. By 22 August 1972, after sending back data and a total of 60 pictures, Mars 2 and 3 concluded their missions. The images and data enabled creation of surface relief maps ...

The mind-bogglingness of the number of loose hematite spherules hits when Figures 22 & 23 are extrapolated to the plain's whole surface area (about 150,000 km 2 [5]): 150,000 km 2 is close to 2/3's the area of the main island of Japan and also 72% the area of the main island of the UK (Great Britain), it is also bigger than the land areas of 30 ...
Deimos (/ ˈ d aɪ m ə s /; systematic designation: Mars II) [11] is the smaller and outer of the two natural satellites of Mars, the other being Phobos. Deimos has a mean radius of 6.2 km (3.9 mi) and takes 30.3 hours to orbit Mars. [5] Deimos is 23,460 km (14,580 mi) from Mars, much farther than Mars's other moon, Phobos. [12]
By 1980, delays in the Space Shuttle program pushed the launch date for Galileo back to 1984. [32] While a Mars slingshot was still possible in 1984, it would no longer be sufficient. [33] NASA decided to launch Galileo on two separate missions, launching the orbiter in February 1984 with the probe following a month later. The orbiter would be ...
Areography, also known as the geography of Mars, is a subfield of planetary science that entails the delineation and characterization of regions on Mars. [1] [2] [3] Areography is mainly focused on what is called physical geography on Earth; that is the distribution of physical features across Mars and their cartographic representations.
