For the very first time, since its arrival on Mars, Curiosity drilled a full hole in Martian rock. The robotic hands used power tools to grind out a sample from a pale, flat slab at a location dubbed "Pahrump Hills".
Previously, Curiosity had drilled into three rocks and had collected powdered tailings for analysis. The analysis was carried out at the much sophisticated onboard laboratories. This time, the drill will provide scientists a tester for the type of sediments that lie ahead.
