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]
[3] [5] [2] The atmosphere of Mars is much thinner and colder than Earth's having a max density 20g/m 3 (about 2% of Earth’s value) with a temperature generally below zero down to -60 Celsius. The average surface pressure is about 610 pascals (0.088 psi) which is 0.6% of the Earth's value. [2]
[9] [26] There can be large temperature swings on Mars, for example at the equator it may reach 70 degrees F (20 degrees C) in the daytime but then go down to minus 100 degrees F (−73 C) at night. [27] Examples of Mars surface temperatures: [27] Average −80 degrees Fahrenheit (−60 degrees Celsius).
The temperature at that time was 37 degrees Fahrenheit (2.8 degrees Celsius). [2] On August 21, 2012, one of two anemometers returned data with errors. After testing it was concluded that it was broken, probably hit by a rock on descent. [7] Martian winds can still be detected with the other sensor. [7]
Mars 1962A was a Mars flyby mission, launched on October 24, 1962, and Mars 1962B an intended first Mars lander mission, launched in late December of the same year (1962). Both failed from either breaking up as they were going into Earth orbit or having the upper stage explode in orbit during the burn to put the spacecraft into trans-Mars ...
The standard measuring conditions for temperature are in the air, 1.25 metres (4.1 ft) to 2.00 metres (6.6 ft) above the ground, [5] and shielded from direct sunlight intensity (hence the term x degrees "in the shade"). [6]
As a result of a runaway greenhouse effect Venus has a temperature of 900 degrees Fahrenheit (475 degrees Celsius), hot enough to melt lead. It is the hottest planet in the Solar System, even more than Mercury, despite being farther away from the Sun. [ 8 ] Likewise, the atmosphere of Venus is almost completely carbon dioxide, and the ...
During a year, there are large surface temperature swings on the surface between −78.5 °C (−109.3 °F) to 5.7 °C (42.3 °F) [c] similar to Earth's seasons, as both planets have significant axial tilt, Earth at 23.5 degrees and Mars at 25 degrees. Mars was formed approximately 4.5 billion years ago.
