Checking Contact Points for Curiosity's Drill
Date: 19 May 2013
This image demonstrates how engineers place the drill carried by NASA's Mars rover Curiosity onto rock targets. They first set down the drill's two stabilizing prongs near the target, as shown by the dashed line. From there, they assess the placement of the prongs in relation to the target to determine the correct, final placement of the drill. This approach allows for higher accuracy, both to hit the target and avoid placing a prong on unstable areas or pebbles.
This image of the "Cumberland" drill target was taken by the Mars Hand Lens Imager (MAHLI) on the 279th Martian day, or sol, of the mission (19 May 2013), from a distance of 25 cm (9.8 inches).
