The ends of the Earth and the end ofMarsare both extreme locations . While the pole of both planets are singular , they share some noteworthy similarity .
" The poles on Mars are a lot like Antarctica , " said James Head , a planetary geologist at Brown University . " It ’s a very waterless , very insensate desert . The Antarctic Dry Valleys , for example , are the most Mars - comparable environment on Earth . "
The poles of Earth and Mars stand out from a distance.
The Martian poles resemble Antarctica , at Earth ’s South Pole , because both are report with a relatively thin layer of ice on top of rock , while our ownNorth Pole is a liquid oceanwith shifting layers of deoxyephedrine floating on top of it .
The ice caps onMarsare roughly as thick as the Methedrine crown on Antarctica — both are about a mile - and - a - half ( two to three kilometre ) deep .
While the ice on Earth is made of pee , Mars ' ice is a combining of water - ice and frosty carbon dioxide , or " ironical ice . "
And if you thought Earth ’s pole were frigid , avoid thetips of Mars , where Earth’s surface temperatures are around 150 Kelvin , or −189.67 degrees Fahrenheit ( -123.15 degrees Celsius ) . Our own South Pole broadly gets down to around −85 degree Fahrenheit ( −65 degrees Celsius ) and our North Pole is much warmer , with lows of around −45 degrees Fahrenheit ( −43 degrees Celsius ) .
gelid bears , sealsand arctic foxes frolic near Earth ’s North Pole , and wench and fish are sometimes sighted there . And Antarctica is base to those adorableEmperor Penguins , as well as Snow Petrel snort , blue whales and orcas . Meanwhile , no liveliness has been regain yet on Mars ' poles ( or anywhere else on the red satellite ) , though scientists are holding out hope for microbes , perhaps in liquid water buried deep under the control surface .
While humans have yet to jell foot on Mars , masses live twelvemonth - round at McMurdo station on Antarctica . For the first explorers to Earth ’s poles , though , the journeying was a challenge consanguine to our current finish of sending astronaut to the red major planet . The first sighting of Antarctica was in the 1820s , and humans did n’t in reality touch down on the southerly continent until the 1890s .
In 1909 , American explorer Robert Peary claim to be the first person to reach the North Pole , though many scholars interview whether he actually achieved this feat .
About a half century after , humans sent the first unmanned missions toMars .
In July 1965,NASA ’s Mariner 4 space vehicle made the first flyby of the planet , snatch the first up - close pic . Ten years by and by , in July 1976 , NASA ’s Viking 1 space vehicle landed on Mars . And this Sunday , NASA ’s Phoenix spacecraft is schedule to countersink down in the northerly polar part of Mars . Scientists hope the approaching delegacy will shake off more Light Within on the difference between our planet and our neighbor , and maybe even chance evidence for the greatest law of similarity of all : life .
