"NASA’s Perseverance rover has captured the clearest ever footage of a solar eclipse over Mars, and the results are out of this world.
The rover snapped the ethereal video of Mars’ potato-shaped moon, Phobos, moving across the face of the sun on April 2. During the eclipse, Phobos projected its uneven shadow over the Martian surface — appearing almost as though it was the pupil of a gigantic eyeball rolling in its socket.
Perseverance recorded the footage midway through its journey to a river delta on Mars’ 28-mile-wide (45 kilometers) Jezero Crater, where it will search for evidence of life on the Red Planet. Training its state-of-the-art Mastcam-Z camera on the sky, the rover recorded the misshapen moon’s solar transit with the greatest zoom and at the highest framerate ever.

"I knew it was going to be good, but I didn't expect it to be this amazing," Rachel Howson, a mission operations specialist at Malin Space Science Systems and one of the Mastcam-Z team members who operates the camera, said in a statement.
Phobos, named after the Greek god of fear, is roughly 157 times smaller than Earth's moon and is one of Mars' two natural satellites, alongside the even smaller Deimos (whose name comes from the Greek god of dread).
Scientists believe that the brother moons were once roaming asteroids that were snared into Mars’ orbit by the planet’s gravitational field. The orbits of these captive asteroids are unstable, according to researchers, and scientists predict that in a few tens of millions of years' time Deimos will spin out into space while Phobos will slam into Mars’ surface."...
