Orbital measurements showed that this dust storm reduced the average temperature of the surface and raised the temperature of the atmosphere of Mars by 30 K. [31] The low density of the Martian atmosphere means that winds of 18 to 22 m/s (65 to 79 km/h) are needed to lift dust from the surface, but since Mars is so dry, the dust can stay in the ...
[129] [130] Mars's atmosphere can be classified into three layers according to the average temperature profile: Troposphere (≈0–40 km): The layer where most of the weather phenomena (e.g. convection and dust storms) take place. Its dynamics is heavily driven by the daytime surface heating and the amount of suspended dust.
[9] The Mars Reconnaissance Orbiter, though spanning a much shorter dataset, shows no warming of planetary average temperature, and a possible cooling. "MCS MY 28 temperatures are an average of 0.9 (daytime) and 1.7 K (night- time) cooler than TES MY 24 measurements."
The average length of a Martian sidereal day is 24 h 37 m 22.663 s (88,642.663 seconds based on SI units), and the length of its solar day is 24 h 39 m 35.244 s (88,775.244 seconds). [3]

There's no Google Earth for Mars — no way to zoom in for a closer look at your Martian neighbors' new deck or pickup truck — but Caltech scientists have spent six years composing a 3D image of ...
Mars is putting on quite a show for skywatchers this month. For most of October, Mars will be brighter in the night sky than anything else in its vicinity, offering people a clear view of the red ...
Temperatures on Mars from REMS on the Curiosity Rover (August 16/17, 2012). Rover Environmental Monitoring Station (REMS) is a weather station on Mars for Curiosity rover contributed by Spain and Finland. [1] [2] REMS measures humidity, pressure, temperature, wind speeds, and ultraviolet radiation on Mars. [3]
