The thermosphere (or the upper atmosphere) is the height region above 85 kilometres (53 mi), while the region between the tropopause and the mesopause is the middle atmosphere (stratosphere and mesosphere) where absorption of solar UV radiation generates the temperature maximum near an altitude of 45 kilometres (28 mi) and causes the ozone layer.
The temperature of the Martian thermosphere increases with altitude and varies by season. The daytime temperature of the upper thermosphere ranges from 175 K (at aphelion) to 240 K (at perihelion) and can reach up to 390 K, [136] [137] but it is still significantly lower than the temperature of Earth's thermosphere.
Each quadrangle is a region covering a specified range of latitudes and longitudes on the Martian surface. The quadrangles are named after classical albedo features , and they are numbered from one to thirty with the prefix "MC" (for "Mars Chart"), [ 1 ] with the numbering running from north to south and from west to east.
The difference between Mars's highest and lowest points is nearly 30 km (from the top of Olympus Mons at an altitude of 21.2 km to Badwater Crater at the bottom of the Hellas impact basin at an altitude of 8.2 km below the datum).
The thermosphere is the second-highest layer of Earth's atmosphere. It extends from the mesopause (which separates it from the mesosphere) at an altitude of about 80 km (50 mi; 260,000 ft) up to the thermopause at an altitude range of 500–1000 km (310–620 mi
The Mare Australe quadrangle is one of a series of 30 quadrangle maps of Mars used by the United States Geological Survey (USGS) Astrogeology Research Program. The Mare Australe quadrangle is also referred to as MC-30 (Mars Chart-30). [1] The quadrangle covers all the area of Mars south of 65°, including the South polar ice cap, and its ...
The most detailed images and observations ever captured of one of Mars' moons have been released by scientists. Pictures taken by Hope Probe from the UAE Space Agency's Emirates Mars Mission (EMM ...
A Mars habitat is a hypothetical place where humans could live on Mars. [2] [3] Mars habitats would have to contend with surface conditions that include almost no oxygen in the air, extreme cold, low pressure, and high radiation. [4] Alternatively, the habitat might be placed underground, which helps solve some problems but creates new ...
