\nThese \u2018yukimarimo\u2019 photographed near the Concordia Research Station were not made by humans for a snowball fight but rather by Antarctic wind.\n<\/p>\n

The resulting layer of hoarfrost that forms on the snow is then broken up by light wind that packs the ice crystals into these balls of fine frost. They then tumble across the Antarctic desert, symbols of the icy continent\u2019s barrenness and desolation, or near desolation.\n<\/p>\n

\nAntarctica\u2019s inhospitable conditions are braved annually by researchers and participants in the name of science. ESA utilises the permanent, year-round French-Italian Concordia Research Station<\/a> to run experiments focusing on human research. In the harsh cold and the alternating six months of complete daylight and total darkness, Antarctica is a unique testing ground for the harsh conditions humans will encounter on exploration missions to Moon, Mars or beyond.\n<\/p>\n

\n"Concordia offers ESA a place to conduct research on people living far away from civilisation in extreme conditions \u2013 much like spaceflight," explains Jennifer Ngo-Anh, ESA’s head of Human Research.\n<\/p>\n

\nHow we adapt physically and psychologically to such extreme environments is the focus of these experiments.  \n<\/p>\n

\nThis year\u2019s team, consisting of an ESA-sponsored medical doctor Carole Dangoisse and 14 other crewmembers, arrived during the Antarctic summer (November to February) and have just passed the six-month mark of their stay. They experienced their last sunrise on 3 May and have since been plunged into a darkness that intensifies daily until the September equinox. According to Dr Dangoisse, the lowest temperature they have recorded so far is \u201373.6 \u00b0C with a wind chill factor of \u201396.8 \u00b0C.\n<\/p>\n

\nThese ‘yukimarimo’ photographed near the Concordia Research Station were not made by humans for a snowball fight but rather by Antarctic wind.\n<\/p>\n

\nDiscovered by Japanese researchers in 1995 – yuki<\/i> meaning ‘snow’ and marimo<\/i> ‘moss balls’ that they resemble – they form when temperatures rapidly drop following a storm. The resulting layer of hoarfrost that forms on the snow is then broken up by light wind that packs the ice crystals into these balls of fine frost. They then tumble across the Antarctic desert, symbols of the icy continent’s barrenness and desolation, or near desolation.\n<\/p>\n
