Precession in the alignment of the obliquity and eccentricity lead to global warming and cooling ('great' summers and winters) with a period of 170,000 years. [132] Like Earth, the obliquity of Mars undergoes periodic changes which can lead to long-lasting changes in climate. Once again, the effect is more pronounced on Mars because it lacks ...
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 ...
Mars is located 142,000,000 miles away from the Sun. Named after the Roman God of war, Mars is widely known for its blood-red color. Chinese astronomers even used to call Mars the 'fire star ...

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 ...
Mars has lots of water, but future astronauts won't exactly be able to scoop it into bottles -- it's generally trapped in ice deposits below the surface. Scientists from Penn State think climate ...
The most popular model for the origin of the ice is climate change from large changes in the tilt of the planet's rotational axis. At times the tilt has even been greater than 80 degrees [ 42 ] [ 43 ] Large changes in the tilt explains many ice-rich features on Mars.
