Unlike vampires or other nocturnal creatures, Perseverance needs rest after long days of exploring the mysterious landscape of Mars. As night falls, the rover sleeps after watching the sun sink below the horizon, casting ominous shadows across the landscape. The chilling wind howls through the night like a haunting lullaby for the intrepid explorer. However, perseverance sometimes wakes up from things that come across in the night. Although instruments usually make their scientific measurements during the day, they are not afraid of the dark and are often tasked with observing what lurks in the shadows and gazing at the night sky on Mars. Perseverance occasionally looks up to image the auroras and catch a glimpse of Phobos and Deimos, the two moons of Mars.
