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.
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 ...
No way that you could scale up to a million people on Mars without something catastrophic happening, either in terms of it turns out we can’t have babies up there, and moms and babies are dying ...

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 ...
The source of Mars methane is unknown; its detection is shown here. The reported presence of methane in the atmosphere of Mars is of interest to many geologists and astrobiologists , [ 1 ] as methane may indicate the presence of microbial life on Mars , or a geochemical process such as volcanism or hydrothermal activity .
The annual question reaches peak curiosity this week, but as the planet warms due to human-caused climate change, the probability of seeing snow at Christmas is becoming increasingly unlikely ...
They conclude that liquid water on today's Mars may be limited to traces of dissolved moisture from the atmosphere and thin films, which are challenging environments for life as it is currently known. [221] An alternative scenario is a Knudsen pump effect, from photophoretic when shadows occurs in a granular material. [222]
