The camera mounted on the Curiosity mast is equipped with a sun filter that acts as a eclipse, so you can safely "stare" at the sun.
The Mars satellite is very small, the Phobos are 7 miles (11.5 kilometers) in diameter, and the Deimos are only 1.5 miles (2.3 kilometers) in diameter. The Phobos eclipse occurred on March 26.
These satellites look like black spots that pass through a bright disc.
These observations help scientists better understand the orbit of each satellite around Mars. "The orbit of the Mars satellite still has some uncertainty, but with every eclipse observed from the surface of the red planet, we can better understand this," NASA said.
Since 2012, the Curiosity probe has been exploring the surface of Mars to overcome technical failures and wheel damage. Its observation of the sun is a good sign and the mission is still in progress.
