The missions could also corroborate these remote sensing datasets with not only their in situ lander metrology booms, [21] but with higher-altitude temperature and pressure sensors for their descent. [22] 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).
The pressure sensor can detect pressures from 1 to 1150 Pa (0.000145038 PSI to 0.1667934 PSI). [11] For comparison, 1 atmosphere is 101,325 Pascals or 14.7 PSI. [12] The air temperature, wind speed and direction sensor for InSight Mars lander (planned for 2018 launch) is based on REMS, also contributed by Spain. [13]

1995 photo of Mars showing approximate size of the polar caps. The planet Mars has two permanent polar ice caps of water ice and some dry ice (frozen carbon dioxide, CO 2).Above kilometer-thick layers of water ice permafrost, slabs of dry ice are deposited during a pole's winter, [1] [2] lying in continuous darkness, causing 25–30% of the atmosphere being deposited annually at either of the ...
where temperature T is in degrees Celsius (°C) and saturation vapor pressure P is in kilopascals (kPa). According to Monteith and Unsworth, "Values of saturation vapour pressure from Tetens' formula are within 1 Pa of exact values up to 35 °C." Murray (1967) provides Tetens' equation for temperatures below 0 °C: [3]
Mars, a world that once gushed with water, is today 1,000 times drier than Earth's driest desert. Yet some ice still flows, slowly, on the Martian ground.NASA's Mars-orbiting satellite, the Mars ...

Scientists have announced the discovery of structures like layering and potential impact craters which had been hidden under Mars’ polar ice caps. New 3-D map of Mars' ice caps reveal hidden ...
