Curiosity Drilled Into a Rock on Mars And Gave Scientists a Big Surprise - ScienceAlert
Overview
On 25 April 2026 the Curiosity rover drilled into a Martian rock and produced an unexpected result that caught scientists off guard. A subsequent account reports the drilling left a fragment stuck to the rover's arm for about five days before it was shaken off, underscoring surprising mechanical and compositional properties of near-surface rocks. These in-situ observations will help refine how researchers assess surface habitability and plan future sampling efforts, and together with NASA's Psyche gravity-assist flyby on May 15 they illustrate how both surface measurements and orbital maneuvers contribute complementary operational lessons.
