JPP7hnR-fXcFollow a fearless team of scientists as they venture into blue holes—underwater caves that formed during the last ice age, when sea level was nearly 400 feet below what it is today. These caves, little-known treasures of the Bahamas, are one of Earth's least explored and most dangerous frontiers. The interdisciplinary team of biologists, climatologists, and anthropologists discover intriguing evidence of the earliest human inhabitants of the islands, find animals seen nowhere else on Earth, and recover a remarkable record of the planet's climate.

An international team of astronauts will go underground this week, using a Mediterranean cave system to help them prepare for life hundreds of miles above Earth's surface.
The six astronauts, who represent five different space agencies, will descend Friday (Sept. 7) into the caves of Sardinia, off the west coast of Italy. They'll stay underground for six days during the 2012 run of the European Space Agency-led CAVES project.
CAVES, which stands for Cooperative Adventure for Valuing and Exercising human behaviour and performance Skills, aims to help prepare astronauts for long-duration spaceflight by exposing them to situations in which they must work together to solve problems in challenging conditions
Cave systems work well as a stand-in for orbiting spacecraft, ESA officials say. Caves, after all, are dark, confined places, and they're isolated from the outside world. Team members will have to adapt to a lack of privacy and comfort, as they would in space as well.
The six astronauts — NASA's Mike Fincke and Andrew Feustel, ESA's Andreas Mogensen, Nikolai Tikhonov of Russia, Japanese spaceflyer Soichi Noguchi and Canadian David Saint-Jacques — have already begun a week-long training session teaching them the basics of cave safety and exploration.
On Friday, the team will descend into the Supramonte cave system of Sardinia's Gennargentu National Park, near the middle of the island....
