2024年2月10日 The Shadow of Ingenuity’s Damaged Rotor Blade Image Credit: NASA, JPL-Caltech, Ingenuity Explanation: On January 18, 2024, during its 72nd flight in the thin Martian atmosphere, autonomous Mars Helicopter Ingenuity rose to an altitude of 12 meters (40 feet) and hovered for 4.5 seconds above the Red Planet. Ingenuity’s 72nd landing was a rough one though. During descent it lost contact with the Perseverance rover about 1 meter above the Martian surface. Ingenuity was able to transmit this image after contact was re-established, showing the shadow of one of its rotor blades likely damaged during landing. And so, after wildly exceeding expectations during over 1,000 days of exploring Mars, the history-making Ingenuity has ended its flight operations. Nicknamed Ginny, Mars Helicopter Ingenuity became the…

2023年11月7日 A Martian Dust Devil Spins By Video Credit: NASA, JPL-Caltech, Perseverance Rover; AI processing: PipploIMP Explanation: It moved across the surface of Mars — what was it? A dust devil. Such spinning columns of rising air are heated by the warm surface and are also common in warm and dry areas on planet Earth. Typically lasting only a few minutes, dust devils become visible as they pick up loose red-colored dust, leaving the darker and heavier sand beneath intact. Dust devils not only look cool — they can leave visible trails, and have been credited with unexpected cleanings of the surfaces of solar panels. The images in the featured AI-interpolated video were captured in early August by the Perseverance rover currently searching for signs…

The Mars Reconnaissance Orbiter (MRO) captured this bit of ursine pareidolia on Dec. 12, 2022. While it resembles a bear we might see on Earth, this is actually a hill on Mars with a peculiar shape. A V-shaped collapse structure makes the nose, two craters form the eyes, and a circular fracture pattern shapes the head. The circular fracture pattern might be due to the settling of a deposit over a buried impact crater. Launched on August 12, 2015, the MRO studies the history of water on Mars and observes small-scale features on the planet’s surface. See more examples of pareidolia—the human tendency to see recognizable shapes in unfamiliar objects or data—from Mars.
