Curiosity switched on its lights during the Martian night, capturing a rare view that is forcing scientists to look at the Red Planet in a new way. Credit: NASA/JPL-Caltech/MSSSWhy The Nevado Sajama Drill Hole Matters To ScientistsThe rock target known as Nevado Sajama was drilled on November 13, 2025, in a region dominated by unusual geological formations called boxwork. Nevado Sajama presented a rare opportunity to revisit this method and test whether subsurface layering could still be observed under controlled lighting conditions. How Curiosity Uses Artificial Light On The Red PlanetThe LEDs used in this experiment are not floodlights designed for panoramic views. Even after more than a decade on Mars, Curiosity is still capable of surprising science by reusing hardware in creative ways.
