NASA’s Perseverance rover has captured the Martian night sky, highlighting Deimos—one of the planet’s two small moons. The image, taken with the rover’s left navigation camera, is a composite of 16 individual frames, each with a 3.28-second exposure, resulting in a total exposure time of about 52 seconds. The photo was transmitted to Earth directly from the rover.
Due to the low light and long exposure time, the image is slightly blurred with noticeable digital noise—many of the white specks in the sky are artifacts. Still, Deimos, which has a diameter of just 12.4 km (7.7 miles), stands out clearly against the Martian night, making this a rare and striking image.
These types of photos help scientists study the orbits and composition of Mars’s moons, as well as surface conditions on the Red Planet during nighttime. Interestingly, in 2024, data from Perseverance helped refine our understanding of Deimos’s albedo, revealing that it reflects more light than previously thought.
