After two decades of drilling, Russian scientists are on the verge of coming into contact with Lake Vostok, Antarctica’s biggest subglacial lake, that has been buried beneath 13,000 ft of ice for more than 20 million years.
Reaching Lake Vostok would represent the first direct contact with what scientists now know is a web of more than 200 subglacial lakes in Antarctica — some of which existed when the continent was connected to Australia and was much warmer. They stay liquid because of heat from the core of the planet.
“This is a huge moment for science and exploration, breaking through to this enormous lake that we didn’t even know existed until the 1990s,” said John Priscu, a researcher at Montana State University who has long been involved in antarctic research, including a study of Vostok ice cores.
“If it goes well, a breakthrough opens up a whole new chapter in our understanding of our planet and possibly moons in our solar system and planets far beyond,” he said. “If it doesn’t go well, it casts a pall over the whole effort to explore this wet underside of Antarctica.”
