A NASA rover on Mars tried to drill into a rock and failed. The target was a flat, fractured stone at a location scientists call Atacama, named after the driest nonpolar desert on Earth, in Chile. The rock was harder than expected, and the rover's drill could not make progress.
A Martian rock that fought back
The Curiosity rover has been exploring Gale Crater on Mars since 2012. In early May 2025, it arrived at a site the science team had nicknamed Atacama. The name was chosen because the landscape reminded researchers of the rugged, arid terrain of Chile's Atacama Desert. The rover's goal was to drill into a flat rock and collect powdered samples for analysis. But when the drill bit touched the surface, it met unexpected resistance. The rock did not crumble. The drill could not penetrate.
Why the team cared
The rover's drill is designed to handle a range of rock hardness, but this particular stone was tougher than most. Engineers on Earth reviewed the data and adjusted the drilling technique. They tried again. The second attempt also failed to make a hole deep enough for sampling. The team decided to move on rather than risk damaging the drill. For the scientists and engineers following Curiosity's daily progress, the setback was a reminder that Mars does not always cooperate. Every drilled sample is a small victory, and this time the planet won.
What happens next
Curiosity drove away from the Atacama site and headed toward a different rock target. The rover continues its slow climb up Mount Sharp, the central peak inside Gale Crater. The team will look for a more drill-friendly stone in the coming weeks. The failed attempt did not harm the rover, and the mission continues as planned.
The struggle at Atacama shows that even after more than a decade on Mars, Curiosity still faces surprises. The planet's geology is complex, and every new location brings unknowns. For the people who operate the rover from millions of kilometers away, patience is part of the job.
