Vostok: Looking for Life Beneath an Antarctic Glacier

Imagine for a moment that you are a strange device called a cryobot. You are a glint in an ocean of snow. You plunge into a hole in the Antarctic ice sheet, drilled by boiling water, and sink rapidly nearly two and a half miles to the bottom of the ice shaft. The pressure crushes in on you in the utter darkness as you purify yourself with a hydrogen peroxide rinse to kill off any surface microbes. At last you reach your destination, your cargo door opens and you release a smaller probe, a hydrobot. Its propeller revs, and it disappears into the gloom on a mission to explore one of our planet's last great virgin territories: Lake Vostok :inlove:


One of at least 76 subglacial lakes recently discovered on that southernmost continent, Vostok is an intriguing proposition for scientists as they ponder how to get down to and explore its stygian depths. This lake, which is capped by ice but does not freeze solid because of heat rising from the Earth's interior, is especially tantalizing because new evidence suggests that life just might exist in its depths. Even more significant, planetary scientists from NASA's Jet Propulsion Laboratory say that Vostok bears an uncanny resemblance to the Jovian moon Europa, which recent spacecraft images suggest is covered by an ocean topped by a rind of ice. JPL scientists are already designing the technology that would one day explore lakes such as Vostok and the ocean on Europa.

Join science writer Richard Stone and learn more about how scientists plan to do this and what life is like working at the Russian's Vostok Research Station. "The weather and tales of hardship have given the Vostochniki, those who work through the long, dark winter there, a reputation for perseverance," writes Stone. The Russians have drilled into the ice sheet, assembling data on the history of the Earth's climate over the past 420,000 years. They've stopped now so as not to contaminate the lake. They are waiting for the right technology to take them the rest of the 400 feet to the lake. It's only a matter of time before we'll get a peek at this lost world. :rolleyes: :cry:


krasota! :p

PS The electronic newspaper Antarctic Sun (www.polar.org), which soon became the main source of information on the Lake Vostok magnetic anomaly, stated that during the initial flight of the SOAR (Support Office for Aerophysical Research), aimed at conducting magnetic resonance imaging over the area, the magnetometer recorded an increase of 1,000 nanoteslas beyond the 60,000 nanoteslas which characterized the Vostok Station. Scientists had expected to find magnetic anomalies in the range of 500 to 600 nanoteslas in areas where volcanic material could be located, but the ranges encountered were simply startling. “This anomaly is so large that it cannot be the product of a daily change in the magnetic field,” stated Michael Studinger, one of the researchers involved in the mapping endeavor.

terrifying! :inlove:

Various microbial organisms found in ice samples gathered from deep beneath Russia's Vostok Station. The ice is thought to be refrozen water from Lake Vostok itself.


magic! :hooray:

I think it IS fascinating as under 4 km of ice there is some micro life that was "untouched" by a human being or "results of our activities" for million years! I am SOOOOOOOOOO curious what's inside! wish I could look at it at least with one eye and at least for a minute! Maybe would notice something WOW!

The Vulcans knew what they were doing when they banned emoticons. :D

aysihsK,
its 5am here in Vladivostok and i'm having trouble sleeping but i'll try reading your posting.
Okay, interesting.............................like the bit about some moon or other, hold on.........................................zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz
