NASA unveils detailed photo of phobos, Mars' "cosmic potato"

NASA published a detailed photo of the moon Phobos, which is on a collision course with Mars. According to the Live Science portal, due to its porous surface structure, the largest Martian moon has been described by scientists as a "cosmic potato."

The moon was photographed using the High Resolution Imaging Science Experiment (HiRISE) camera on the Mars Reconnaissance Orbiter (MRO) board.

The MRO was launched from Earth on August 12, 2005, and reached Martian orbit on March 10, 2006. Now, NASA has published the photo, calling the largest Martian moon a "cosmic potato."

Phobos, named after the Greek god of fear, is about 253 times smaller than Earth's Moon. Its dimensions are approximately 27 km by 23 km by 18 km. It orbits the planet three times a day, so close to its surface that it is not always visible in some places on Mars.

It is on a collision course, approaching the planet at a speed of 1.8 mm per year. Its surface is porous and shows traces of thousands of meteorite impacts.

It is one of the two natural satellites of the Red Planet, alongside the smaller Deimos, whose name comes from the Greek god of terror.

NASA scientists claim that the sister moons were wandering rocks in space captured into Mars' orbit by the planet's gravitational field.

According to them, the uneven surface of Phobos suggests that it was once a comet from the asteroid belt between Mars and Jupiter.

Scientists believe the orbits of both moons are very unstable. They predict that in tens of millions of years, Deimos will leave Martian orbit while Phobos will either break up as it approaches Mars' surface or crash into it. According to NASA, however, it is unlikely that this event will occur within the next 50 million years.
