The large eccentricity causes the insolation on Mars to vary as the planet orbits the Sun. (The Martian year lasts 687 days, roughly 2 Earth years.) As on Earth, Mars' obliquity dominates the seasons but, because of the large eccentricity, winters in the southern hemisphere are long and cold while those in the north are short and relatively warm.
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 ...
William Feldman speculates the warming could be because Mars might be coming out of an ice age. [15] Other scientists state the warming may be a result of albedo changes from dust storms. [16] [17] The study predicts the planet could continue to warm, as a result of positive feedback. [17]
The idea of transforming Mars into a world more hospitable to human habitation is a regular feature of science fiction. Scientists are now proposing a new approach to warm up Earth's planetary ...
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 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 ...
For the lucky astronauts on a mission to Mars, there will be no shortage of things to worry about during the two-year round trip. Going to Mars will involve all sorts of risks. Going bonkers might ...

The Mars Global Surveyor, launched on November 7, 1996, has been an effective spacecraft that has orbited and measured the surface of Mars thousands of times. Among the various instruments on the Mars Global Surveyor, the Mars Orbiter Laser Altimeter (MOLA) and Thermal Emission Spectrometer (TES) are used to map the topography of Mars and study the surface and atmosphere of the planet.
