NASA’s Perseverance rover captured this view of Deimos, the smaller of Mars’ two moons, shining within the sky at 4:27 a.m. native time on March 1, 2025, the 1,433rd Martian day, or sol, of the mission. At the hours of darkness earlier than daybreak, the rover’s left navigation digital camera used its most long-exposure time of three.28 seconds for every of 16 particular person photographs, all of which had been mixed onboard the digital camera right into a single picture that was later despatched to Earth. In complete, the picture represents an publicity time of about 52 seconds.
The low gentle and lengthy exposures add digital noise, making the picture hazy. Most of the white specks seen within the sky are possible noise; some could also be cosmic rays. Two of the brighter white specks are Regulus and Algieba, stars which can be a part of the constellation Leo.
