Things That Go Bumps at Night on Mars

The two tiny moons of Mars, Phobos and Deimos, as well as the stars' illumination allow you to faintly discern the outline of the impending delta

Then, out of nowhere, a mechanical whirring sound from another planet appears, and a malformed head emerges from the shadows with five menacingly glinting eyes

But do not be alarmed; this is Perseverance going about its normal job, not a phantom monster or a vengeful Martian

Temperatures drop at night, which means more energy is required to keep things warm, leaving less time for science

The SuperCam microphone regularly records three-minute high-frequency sound recordings overnight, which reveal small-scale atmospheric turbulence

The oxygen generating runs for the MOXIE (Mars Oxygen In-Situ Resource Utilization Experiment) are typically scheduled at night as well

Because density is related to pressure divided by temperature, air is densest at night due to lower air temperatures

This gives a visible light measurement of nighttime dust abundance, which may be compared to daytime sun observations with MEDA's infrared nighttime dust abundance data

Mars 2020 team members in Hawaii must start work at 3am since rover operations shifts can start as early as 6am Pacific Time on Earth

However, rover operations can start later in the day and end in the late evening Pacific Time, meaning Mars 2020 team members in Europe don't get to sleep until their morning
