Summary
ScienceDaily republishes a NASA release describing a rare drill mishap by the curiosity-rover in gale-crater on Mars. On April 25, 2026, while drilling a rock the team named “Atacama” (~1.5 ft across, ~6 in thick, ~28.6 lb / 13 kg), the entire rock lifted out of the Martian surface and stuck to the fixed sleeve around the spinning drill bit. Hazcams and navcams documented the multi-day effort to free it. Engineers tried drill vibration (April 25), then a repositioned arm with renewed vibration (April 29), and finally a combination of steeper drill angles, rotation, vibration, and bit-spinning on May 1, which broke the rock free on the first try; it fractured on impact with the ground. NASA notes this is the first time a rock has remained attached to the drill sleeve itself, though prior drills had cracked or separated rock layers. Operationally interesting but not a life-detection result — included for vault completeness during the post-TMAH-organics period for Curiosity (src-curiosity-mars-life-molecules-2026-04, src-mars-organics-fresh-clues-2026-04).
Key Claims
- On 2026-04-25 Curiosity drilled a Martian rock dubbed “Atacama”; the rock lifted out of the surface and remained attached to the drill sleeve.
- Rock dimensions: ~1.5 ft across at base, ~6 in thick, ~28.6 lb (13 kg).
- First-of-its-kind in the Curiosity mission — prior drill incidents only cracked or layered rocks; none stuck to the sleeve.
- Vibration alone (April 25) had no visible effect.
- On April 29, arm reposition + renewed vibration spilled sand from the rock but did not detach it.
- On May 1, combined steep-angle + rotation + vibration + bit-spin freed the rock on the first attempt; it fractured on landing.
- Sequence was documented by Curiosity’s front hazcams and mast navcams.
- Mission operated by nasa-jpl (managed by caltech) for nasa’s Science Mission Directorate / Mars Exploration Program.
