"After the recent streak of robotic failures that we've seen, it's refreshing to see yet another success story come our way. Just as it did in February, the two-meter wide DepthX (Deep Phreatic Thermal Explorer) robotic submarine successfully mapped out a massive sinkhole in Mexico, but this time was quite a bit more rewarding. The cavern that it ventured into was the El Zacat&amp;oacute;n Cenote, which is better known as the world's deepest water-filled sinkhole, and the machine was able to delve some 270-meters down to \"create the first map of the giant cavity.\" The hole itself is large enough to \"swallow New York's Chrysler Building,\" and while the endeavor was indeed a success, researchers are hoping to get it back down there in the near future to better analyze a mysterious slope that it wasn't quite able to probe. Godspeed, DepthX.[Via Slashdot]"^^<http://www.w3.org/2001/XMLSchema#string>
