It is believed that it will one day crash into Mars, possibly in as little as 10 million years. Once Phobos gets down to an altitude of only 2,250 miles (3,620 km) above the surface of Mars, it will enter what's known as the Roche limit. At this point, the tidal forces of Mars will begin to tear the small moon apart.
Also question is, why is Phobos important to Mars exploration?
Fuller calls Phobos a “180-degree radiation shield,” which reduces risk to the human crew that is tasked with residing in the Martian system before heading to the planet.
One may also ask, how long until Phobos hit Mars?
Phobos gets closer to Mars by about 2 meters every one hundred years, and it is predicted that within 30 to 50 million years it will either collide with the planet, or break up into a planetary ring.
What is the Phobos incident?
The Phobos (Russian: Фобос, Fobos, Greek: Φόβος) program was an unmanned space mission consisting of two probes launched by the Soviet Union to study Mars and its moons Phobos and Deimos. Phobos 1 suffered a terminal failure en route to Mars.
Why is Mars moon doomed?
Its proximity to its planet is one of the reasons astronomers were unable to see the satellite until the late 19th century. In fact, the moon is getting closer to Mars over the centuries, and eventually will either break up or be pulled into the Martian surface.
