正文(英文) | This year marks two decades since the first ESA doctor set foot in Antarctica, running research at one of the most extreme places on Earth in preparation to explore far beyond it. The crew of Italian-French research station, Concordia, in Antarctica, are subjected to almost nine months of complete isolation per year. The station’s location, at 3233 m altitude, means inhabitants also experience chronic hypobaric hypoxia – lack of oxygen to the brain – making it an ideal environment to better understand how humans adapt and survive in extreme conditions. ![]() During the Antarctic winter, the crew of up to 15 people also endure four months of complete darkness: the sun disappears from May and is not seen again until late August. Temperatures can drop to –80°C in the winter, with a yearly average of –50°C. After reviewing 20 years of space research on Earth, researchers have established sound knowledge on this topic. Some of the tips below will come as no surprise, but solidifying this research is what helps space agencies choose astronauts who will explore farther, and achieve their mission – whether that is on the Moon, Mars or elsewhere. ![]()
![]() “Most of these tips should not come as a surprise, but this recap of 20 years of research and the research behind the tips above were ground-breaking at the time, they have now become common knowledge,” says Jennifer Ngo-Anh, research coordinator for ESA’s human and robotic exploration. “It is important to have scientific justification behind our strategy for selecting and training astronauts as we design and prepare for missions farther into our Solar System,” continues Jennifer, “also there are always surprises whereby diligent research has shown the opposite of what was expected.” ![]() Travelling on long-haul flights has long been associated with deep vein thrombosis, or blood clots in the legs. The lower air pressure coupled with little movement sitting in aircraft seats were logical factors to blame, but research on the crew at Concordia showed, surprisingly, that the lower air pressure did not seem to have an effect. “Science is about showing new, unexpected correlations, but also proving what is generally well accepted. Here’s to 20 years of science in Antarctica and many more to come,” concludes Jennifer. ![]()
