Curiosity rover dislodges rock stuck to drill sleeve on Mars

NASA said the 13-kilogram slab, lifted during a 25 April drilling attempt on the Atacama target, finally came free on 1 May after the team tilted, rotated and vibrated the drill.
The rock fractured when it hit the ground, ending an unprecedented incident in Curiosity's 13.5 years on Mars that highlighted how unpredictable Martian rock structure can be during drilling.
The episode adds to Curiosity's long history of drill troubles, including failures that halted drilling in 2016-18, but the rover has still delivered major findings since landing in Gale Crater in 2012.
After this unprecedented drill failure, how will NASA redesign future Mars rovers to handle the planet's unpredictable terrain?
Curiosity found organics and later groundwater. How does this dual discovery reshape the timeline for potential ancient life on Mars?
With Mars Sample Return canceled, can rovers alone ever prove if newly found organic molecules came from ancient Martian life?
Overcoming the Atacama Rock Challenge: How Curiosity Freed a 28.6-Pound Martian Block After a Week-Long Drill Incident
Overview
In April 2026, NASA's Curiosity rover drilled into the 'Atacama' rock on Mars, but the rock unexpectedly stuck to the drill sleeve and was lifted out of the ground. Initial attempts to free it using vibration and repositioning failed due to the rock's strong cohesion, tight friction fit with the drill sleeve, and Mars' low gravity. On May 1, the rover team executed a complex maneuver combining drill tilting, sustained percussion, and high-speed bit spinning, successfully fracturing and releasing the rock. During this time, Curiosity continued scientific observations with other instruments. This incident showcased the rover team's ingenuity and resilience, building on past engineering advances to overcome unforeseen challenges and gain valuable scientific insights.
