NASA’s Curiosity rover remains steadfast in its mission to explore the Martian surface, only briefly hindered when its drill became lodged in a stubborn rock.
The incident occurred on April 25, during what was planned as the rover’s second drilling session on a 28.6-pound, 18-inch-wide, and 6-inch-thick rock named Atacama. When Curiosity attempted to retract its drill arm, the rock unexpectedly adhered to the protective sleeve encasing the drill bit, causing it to be pulled along.
Mission engineers on Earth initially tried to dislodge the rock by gently shaking the drill arm, akin to a mechanic trying to free a stuck bolt with careful taps, but this approach failed. Subsequent attempts involved activating the drill’s vibration mechanism to loosen the rock, which also proved ineffective. Finally, on May 1, a combination of tilting, rotating the drill, and spinning the bit successfully freed the rock, which fragmented upon release.

The fragments from the Atacama rock will be examined by Curiosity’s Chemistry and Mineralogy (CheMin) instrument. These samples will be compared with those collected from Mineral King, a site located approximately 525 feet downhill from the rover’s current position.
With the drill now operational, Curiosity resumes its scientific investigations within Gale Crater, where it has been conducting research for over 14 years-equivalent to nearly a decade and a half of Martian seasons. Presently, the rover’s Earth-based environmental team is leveraging its instruments to monitor Martian atmospheric dust levels, track cloud formations, and observe transient dust devils-small whirlwinds that briefly stir the planet’s surface.
