Scientists this week begin the final leg of a five-year, NASA-funded mission to reach the bottom of Cenote Zacatón in Mexico, the world’s deepest known sinkhole.
No one has ever reached bottom and at least one diver has died in the attempt. Scientists want to learn more about Cenote Zacatón's physical dimensions, the geothermal vents that feed it and the forms of life that exist in its murky depths.
The mission’s progress can be monitored at two Web sites: geology.com
, and the Robotics Institute’s DEPTHX Web site, www.frc.ri.cmu.edu
, which will feature daily updates, images and graphics.
