Differing in situ values have been reported for the average temperature on Mars, [23] with a common value being −63 °C (210 K; −81 °F). [24] [25] Surface temperatures may reach a high of about 20 °C (293 K; 68 °F) at noon, at the equator, and a low of about −153 °C (120 K; −243 °F) at the poles. [26]
The history of Mars observation is about the recorded history of observation of the planet Mars. Some of the early records of Mars' observation date back to the era of the ancient Egyptian astronomers in the 2nd millennium BCE. Chinese records about the motions of Mars appeared before the founding of the Zhou dynasty (1045 BCE).
The highest natural ground surface temperature ever recorded may have been an alleged reading of 93.9 °C (201.0 °F) at Furnace Creek, California, United States, on 15 July 1972. [7] In 2011, a ground temperature of 84 °C (183.2 °F) was recorded in Port Sudan, Sudan. [8] The theoretical maximum possible ground surface temperature has been ...

Olympus Mons (/ əˌlɪmpəs ˈmɒnz, oʊ -/; [4] Latin for ' Mount Olympus ') is a large shield volcano on Mars. It is over 21.9 km (13.6 mi; 72,000 ft) high as measured by the Mars Orbiter Laser Altimeter (MOLA), [5] about 2.5 times the elevation of Mount Everest above sea level. It is Mars's tallest volcano, its tallest planetary mountain ...
The highest atmospheric density on Mars is equal to the density found 35 km (22 mi) above the Earth's surface and is ≈0.020 kg/m 3. [7] The atmosphere of Mars has been losing mass to space since the planet's core slowed down, and the leakage of gases still continues today. [4] [8] [9]
The crater depth is 7,152 m (23,465 ft) below the standard topographic datum of Mars. [1] Hellas Planitia / ˈhɛləs pləˈnɪʃiə / is a plain located within the huge, roughly circular impact basin Hellas[a] located in the southern hemisphere of the planet Mars. [3] Hellas is the third- or fourth-largest known impact crater in the Solar System.
The current official highest registered air temperature on Earth is 56.7 °C (134.1 °F), recorded on 10 July 1913 at Furnace Creek Ranch, in Death Valley in the United States. [1] For few years, a former record that was measured in Libya had been in place, until it was decertified in 2012 based on evidence that it was an erroneous reading.
