DEPTHX Tests Resume
Prototype Space Probe Prepares To Explore Earth’s Deepest Sinkhole
“Scientists return this week to the world’s deepest known sinkhole, Cenote Zacaton in Mexico, to resume tests of a NASA-funded robot called DEPTHX, designed to survey and explore for life in one of Earth’s most extreme regions and potentially in outer space. If all goes well with this second round of testing and exploration, the team will return in May for a full-scale exploration of the Zacaton system.”
