NASA’s Curiosity Rover Frees Its Drill From a Rock

A black-and-white GIF shows the view from the chassis of the Curiosity Mars rover as its robotic arm drills into a rock, then lifts up out of the ground.. The rover’s arm moves around and sand can be seen falling off the rock. The rover’s arm can be seen reorienting the drill more, and finally the rock falls off and fractures. The view, across an expanse of rocks, stretches into the distance with mountains visible in the background.

Description

This series of images shows NASA’s Curiosity Mars rover as it got a rock stuck to the drill on the end of its robotic arm and, after waving the arm and running the drill a few times, finally detached the rock. The imagery showing the entire process was captured by the black-and-white hazard cameras on the front of Curiosity’s chassis and by navigation cameras on its mast, or head.

On April 25, 2026, Curiosity drilled a sample from a rock nicknamed “Atacama,” which is an estimated 1.5 feet in diameter at its base, 6 inches thick and weighs roughly 28.6 pounds (13 kilograms). When the rover retracted its arm, the entire rock lifted out of the ground, suspended by the fixed sleeve that surrounds the rotating drill bit. Drilling has fractured or separated the upper layers of rocks in the past, but a rock has never remained attached to the drill sleeve. The team initially tried vibrating the drill to shake off the rock, but saw no change.

Then, on April 29, they tried reorienting Curiosity’s robotic arm and vibrating the drill again. Imagery in the GIF shows sand falling from Atacama, but the rock stayed attached to the rover.

Finally, on May 1, Curiosity’s team tried again, tilting the drill more, rotating and vibrating the drill, and spinning the drill bit. The team planned to perform these actions multiple times but the rock came off on the first round, fracturing as it hit the ground.

A black-and-white GIF shows the Curiosity Mars rover’s robotic arm drilling into a rock, which lifts up out of the ground. Yellow time stamps in the upper left corner indicate the date and time of each image. The rover’s arm moves around and sand can be seen falling off the rock. The rover’s arm can be seen reorienting the drill more, and finally the rock falls off and fractures. The view, across an expanse of rocks, stretches into the distance with mountains visible in the background.

Curiosity was built by NASA’s Jet Propulsion Laboratory, which is managed by Caltech in Pasadena, California. JPL leads the mission on behalf of NASA’s Science Mission Directorate in Washington as part of NASA’s Mars Exploration Program portfolio.
