NASA’s Perseverance rover<\/a> captured this view of Deimos, the smaller of Mars’ two moons, shining in the sky at 4:27 a.m. local time on March 1, 2025, the 1,433rd Martian day, or sol, of the mission. In the dark before dawn, the rover’s left navigation camera used its maximum long-exposure time of 3.28 seconds for each of 16 individual shots, all of which were combined onboard the camera into a single image that was later sent to Earth. In total, the image represents an exposure time of about 52 seconds.<\/p>\n

The low light and long exposures add digital noise, making the image hazy. Many of the white specks seen in the sky are likely noise; some may be cosmic rays. Two of the brighter white specks are Regulus and Algieba, stars that are part of the constellation Leo.<\/p>\n
