The second attempt by Curiosity to drill into Vera Rubin Ridge was a failure, the rock once again being too hard using the rover’s new improvised drilling technique.
They are now in search of “softer rock.” The scientists very much want to get at least one drill hole in the hematite unit on Vera Rubin Ridge. However, it does appear that the new drill technique, that uses the robot arm to push the drill bit down as its drills, does not provide enough force for some hard geological features.
The failure to drill is in itself not a complete scientific washout. Knowing the hardness of a rock can tell a geologist a great deal about it. Nonetheless, the Curiosity science team seems determined to find something they can drill into on Vera Rubin Ridge.
