Cliffbot goes Climbing
From Astrobiology Magazine, European Edition is a story about a rover that can scale the steep sides of cliffs and craters. Developed by a group of NASA engineers, this three-rover system, modeled on tether-aided human climbing, could make such locations on Mars accessible for future exploration.Source: [Astrobiology Magazine]

Cassini Flies Through Watery Plumes of Enceladus
NASA’s Cassini spacecraft performed a daring flyby of Saturn’s moon Enceladus on Wed., March 12, flying about 15 kilometers per second (32,000 mph) through icy water geyser-like jets. The spacecraft snatched up precious samples that might point to a water ocean or organics inside the little moon.

How Low Can Geologists Go?
Scientists have begun 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.
Previous expeditions tested the robotic probe that will make the dive. The Deep Phreatic Thermal Explorer, known as DEPTHX, is a tangerine-shaped submarine designed to survey...
