They are trying to cross 4000 kilometers on foot in the south pole to assess the limits of human beings and whether human beings can survive on Mars in the future < p > the two men are Justin packshaw, a 57 year old veteran, and Jamie face children, a 37 year old doctor and former army doctor. They tried to reach the most isolated place on the Antarctic continent, the so-called "pole of accessibility", within 80 days < p > parkshaw and childs set out three weeks ago and are currently working with NASA, the European Space Agency (ESA) and Stanford University to study how people should cope when their bodies reach their limits. Scientists believe that the inhospitable conditions and strange and desolate landscape in Antarctica may be similar to those faced by astronauts on missions to the moon and Mars < p > parkshaw and childs were tested twice a week to see how the trip had affected their body and mind. Their saliva, blood, urine and fecal samples are stored to monitor the performance of their immune system during hiking < p > when crossing ice peaks and ice fields, the two also wear smart watches to monitor their vital signs, stress level and sleep quality, because they bear the severe cold of minus 31 ℃ and the strong wind of 160 kilometers per hour. Parker Shaw and childs did not have mechanical assistance and relied entirely on their own strength. Only kites helped them travel on foot and snowboard, while each dragged a 200 kg sled < p > as part of "psychophysics" research, NASA is also testing the eyesight of two explorers. "Psychophysics" studies the relationship between the physical stimuli people experience and the feelings they produce < p > in addition to monitoring the explorers themselves, experts are also collecting data about the environment. Parkshaw and childs measure radiation levels, ultraviolet levels and common meteorological data such as temperature, wind speed and snow density every day. Parkshaw and childs hope to complete their journey in early February next year. (small) < / P > < p >
