Extremeophiles and Extreme Environments: December 2008

This past October 29th, Nathalie Cabrol of NASA Ames Research Center and her team traveled to the highest volcanic lakes in the world to continue her work on the NAI-funded High Lakes Project (HLP). At this time, in the 6th year of the project, the team is, right now, busy collecting data to characterize the response of these lakes to climate variability in one of the best terrestrial environmental analogs to early Mars.

To share in the ongoing adventure, see this project's blog, read up on the science and enjoy some great pictures, visit the project website at

Scientists have brought the ENDURANCE underwater vehicle to Lake Bonney, a perpetually ice-covered salt lake located in Antarctica's McMurdo Dry Valleys.

ENDURANCE, an autonomous vehicle designed to swim untethered under ice, will spend a month creating three-dimensional maps of the underwater environment. It also will collect data on the environmental conditions and take samples of microbial life. If all goes well, in the future NASA could send a similar probe to explore the ocean on Jupiter's icy moon Europa.

Read the daily blog entries written by scientists in the field as they work in Earth's coldest environment, testing the limits of ENDURANCE.
