Concordia crew on one of the wooden observation platforms near the living quarters.
Wood is an excellent material to build with in Antarctica as it is light-weight and does not rot. No microbes that degrade wood over time can withstand the extreme weather.
Aside from the crew staying at Concordia research base no living beings can be found in a 600 km radius.
ESA sponsors a research medical doctor each year to study the effects of living in isolation. The extreme cold, isolation, sensory deprivation and remoteness make living in Concordia similar to living on another planet.
