有时似乎我们的星球上没有什么秘密了，但是在南极巨大冰盖的深处，科学家们做出了惊人的发现。他们发现了世界上最大的湖泊之一。它的存在确实违背了信念。科学家们迫切希望进入该湖，因为它的极端环境可能是以前从未见过的独特动植物的家园，而美国宇航局对它可以教给我们关于外星生命的知识感到兴奋。但是在湖泊和地表之间有4公里的冰层，在不污染地球上最原始水域的情况下打破这种密封可能是21世纪科学面临的最大挑战之一.1957年，俄罗斯人建立了一个偏远的基地在南极洲-东方站。它很快就成了艰辛的代名词-依靠每年从海岸获得的史诗般的1000公里拖拉机运输来获得补给。1983年7月21日，这里记录到地球上最冷的温度（-89°C）。对于液态水湖来说，这是不太可能的设置。但是在1970年，一个英国小组使用机载雷达在冰层下看了一下，绘制了南极冰原掩埋的山区。在沃斯托克基地附近飞行时，他们的雷达迹线突然变平了。他们猜测平坦的痕迹只能来自水。这是冰可能隐藏了一个巨大秘密的第一个证据。一个英国团队使用机载雷达观察冰层下方，绘制出南极冰原掩埋的山区。在沃斯托克基地附近飞行时，他们的雷达迹线突然变平了。他们猜测平坦的痕迹只能来自水。这是冰可能隐藏了一个巨大秘密的第一个证据。一个英国团队使用机载雷达观察冰层下方，绘制出南极冰原掩埋的山区。在沃斯托克基地附近飞行时，他们的雷达迹线突然变平了。他们猜测平坦的痕迹只能来自水。这是冰可能隐藏了一个巨大秘密的第一个证据。It sometimes seems as if our planet has no secrets left - but deep beneath the great Antarctic ice sheet scientists have made an astonishing discovery. They’ve found one of the largest lakes in the world. It’s very existence defies belief. Scientists are desperate to get into the lake because its extreme environment may be home to unique flora and fauna, never seen before, and NASA are excited by what it could teach us about extraterrestrial life. But 4 kilometres of ice stand between the lake and the surface, and breaking this seal without contaminating the most pristine body of water on the planet is possibly one of the greatest challenges science faces in the 21st century.In 1957 the Russians established a remote base in Antarctica - the Vostok station. It soon became a byword for hardship - dependent on an epic annual 1000km tractor journey from the coast for its supplies. The coldest temperature ever found on Earth (-89°C) was recorded here on the 21st July 1983. It’s an unlikely setting for a lake of liquid water. But in the 1970’s a British team used airborne radar to see beneath the ice, mapping the mountainous land buried by the Antarctic ice sheet. Flying near the Vostok base their radar trace suddenly went flat. They guessed that the flat trace could only be from water. It was the first evidence that the ice could be hiding a great secret.
