They want to learn more about its physical dimensions, the geothermal vents that feed it and the forms of life that exist in its murky depths. Now, they’ll be using a robotic probe.
Known as the DEPTHX (for Deep Phreatic Thermal Explorer), the probe is a tangerine-shaped submarine designed to survey and explore for life in extreme regions on Earth and potentially in outer space.
During eight years of research at Zacatón, doctoral student Marcus Gary, who coordinates the DEPTHX mission, and hydrogeology professor Jack Sharp, both from the University of Texas at Austin’s Jackson School of Geosciences, USA, discovered the system’s unusual hydrothermal nature is analogous to liquid oceans under the icy surface of Jupiter’s moon Europa.
Technology developed to explore the sinkholes could be applied to future space probes of Europa, where scientists believe that deep cracks and holes in the ice offer a chance of finding extraterrestrial life.
The DEPTHX technology has also been approved for a new NASA mission to explore one of Antarctica’s ice-bound polar lakes.
Researchers believe ice-bound lakes hold clues to the origins of life on Earth.

Unique in the world of robotic explorers, DEPTHX is autonomous. The probe does not rely on instructions from humans to decide where to go or what to do. Using software
developed by Carnegie Mellon graduate student Nathaniel Fairfield, DEPTHX creates 3D maps of previously unexplored areas as it swims along and then uses those same maps to navigate back to the surface.
The mission’s progress can be monitored from two Web sites. The University of Texas at Austin’s Jackson School of Geosciences will maintain a daily blog of the mission which began May 16
