NASA's Perseverance rover captured images of Mars' potato-shaped moon as it crosses the surface
Eclipse captured by Perseverance Mastcam-Zthe next generation on April 2, on the 397th Martian day (or sol), lasted just over 40 seconds. This is much shorter than a typical solar eclipse involving Earth's moon. The fact is that Phobos is about 157 times smaller than it. Another moon of Mars, Deimos, is even smaller than Phobos.
Perseverance landing in February 2021,provided a detailed video of the Phobos solar eclipse at the highest frame rate ever. This is made possible thanks to the new generation Mastcam-Z camera system, which is an improved version of the Mastcam installed on Curiosity.
Scientists are interested in studying Phobos.As it orbits Mars, its gravity exerts a slight tidal effect on the interior of the Red Planet, slightly warping the rocks in the crust and mantle. These forces are also slowly changing the orbit of Phobos. As a result, geophysicists can use these changes to better understand how malleable the interior of Mars is and learn more about its structure.
