Because the early 20th century, a large number of expeditions have penetrated within the Antarctic Continent, which has led the spirit of analysis and medical passion. Amongst them stand out with the feats of Street Amundsen and Robert Scot, who began in 1911. years at the epic race to achieve the South Pole, situated at the Plateau Antarctica.
Antarctic plateau is a large extension of ice to greater than 3,000 meters above sea degree, with extraordinarily chilly and dry prerequisites. It’s situated within the coldest level on Earth, registered at -89 ° C at Vostok Station.
Chilly and attraity The plateau prohibit the supply of liquid water, distracting existence on this atmosphere. On the other hand, it does no longer impose that.
In our ultimate find out about, we discovered micro organism trapped for many years within the ice and analyzed its resemblance to micro organism that have been first trapped within the air Antarctic plateau.
Those analyzes have been discovered that one day of ice micro organism have been transported by means of wind from other portions of the continent, the ocean that surrounds and even additional puts, to finish their adventure on this massive frozen extension. Over time, this LED has turn into a microbial historic document coping with knowledge on environmental prerequisites up to now.
Board the wind Sank
Attaining on Plateaou Antarctica to make the analysis isn’t simple; It’s a super logistic problem.
Maximum Antarctic databases are coastal and plateau is an icy wilderness. So how are we able to get there? The solution is in nature: with the wind, like micro organism.
Within the south of the summer time, 2018-2019-2019, 4 researchers crossed 2,578 km in Antarctic plateau that led the wind. They traveled complex windshield, with one wind at the room on the planet, invented researcher Ramon Larramendi. The wind with Sanjak has the capability to deal with 2,000 kg a lot and strikes to a plateau with out producing greenhouse fuel emissions.
The researchers went from the close to Antarctic base of Novolazarevskaia, they arrived in Fuji Dome and returned to the start line, creating a round crossing.
All over the path, the ice samples as much as 4 meters have been captured, the captured airmelon microorganisms with a microorganism collector we invented for this expedition and carry out experiments within the “mobile laboratory” that they put in inside of one in every of their tents.

By means of courtesy of the windshield, CC would-from microbial existence underneath excessive prerequisites
The wind staff analyzed microbial existence on ice throughout the transition. They wore LDCHIP (chip of existence detector), an immune take a look at with greater than 200 antibodies for identity of microorganisms.
LDCHIP is a middle of a forged device (indicators of existence detector), designed to come across microbial and residues on planetary analysis.
The samples later moved to Spain to accomplish extra research. The effects have found out the presence of DNA other teams of micro organism within the air and in ice.
As well as, we controlled to insulate and develop within the Laboratory of cyanobacteria discovered 4 meters deep in ice, which corresponds to about 40 years. This presentations the sustainability of a few microorganisms regardless of the a long time are uncovered to dry and chilly prerequisites.
DNA research allowed this cyanobacteria to categorise as GloeOcapsisis Sp. This can be a genus of maximum cianobacteria, which is, which will face up to environmentally pleasant prerequisites that might be fatal for many residing beings.
This style produces sugars to offer protection to towards condemnation and freezing. Some sugars had been expelled outdoor the mobile, forming a thick layer that stops from exuding. The opposite accumulates them within to cut back the purpose of freezing water within the mobile, fighting the formation of ice crystals can injury mobile membranes throughout freezing.

The presence of residing microorganisms within the intensity of Antarctic ice feeds hope in the potential for existence, pasted or provide, different puts outdoor the rustic.
Antarctic plateau is similar with different planetary environments, in order that the existence on this atmosphere is helping within the alternative to exist within the Ice Underground of Mars or Europe (Luna de Juper), particular spersiral clipper NASA and ESA Spring .

The speculation of the life of microbial existence on Mars or different portions outdoor the rustic is in line with conceivable formation of salmuelas that scale back freezing level and retain liquid water.
Mars has a large distribution of perhlateral salts that may choose the presence of liquid water at temperatures underneath 0. To substantiate this risk, the salt experiment used to be performed within the wind that broke during the commute. The effects published the presence of environmental prerequisites suitable with liquid water formation.
Those effects support the speculation of conceivable life of microbial existence on Mars.
