The Antares project "Mars Small-Scale Weather" (MSW) has recently identified some minor weaknesses in current global climate models (GCMs) due to the GCMs' more primitive soil modeling. "Heat admission to the ground and back is quite important in Mars, so soil schemes have to be quite accurate."
The atmosphere of Mars is colder than Earth’s owing to the larger distance from the Sun, receiving less solar energy and has a lower effective temperature, which is about 210 K (−63 °C; −82 °F). [2] The average surface emission temperature of Mars is just 215 K (−58 °C; −73 °F), which is comparable to inland Antarctica.
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]
The instruments may lack the sensitivity to find evidence of microbial life, researchers have said.
Knowing how the hematite on Mars was formed may help scientists characterize the past environment and determine whether that environment provided favorable conditions for life. "Grey hematite is a mineral indicator of past water," said Dr. Joy Crisp, JPL project scientist.
Curiosity's hard work is once again paying off by turning up evidence that liquid water quite likely exists on Mars at this time. A paper published in Nature Geoscience reveals that data collected ...
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 ...
LOS ANGELES (Reuters) -NASA's rover Perseverance has gathered data confirming the existence of ancient lake sediments deposited by water that once filled a giant basin on Mars called Jerezo Crater ...
