SCIENTISTS are testing a robot in one of the world's deepest sinkholes, which happens to be located in El Zacaton, Mexico.
Here's an excerpt from the Los Angeles Times story:
EL ZACATON, MEXICO--NASA is testing a robot in one of Earth's deepest sinkholes in a first step toward searching for life on Jupiter's icy moon, Europa. El Zacaton, near the Gulf Coast of northeastern Mexico, is about 328 feet wide and 1,000 feet deep. Over the next two weeks, scientists plan to map and take samples in the dark, water-filled fissure with the 1.5-ton DEPTHX robot. It's a prelude to the proposed navigation of Europa's ice-capped oceans in about 20 years.
