CELL DATA AND OFFICIAL COMMUNICATIONS BETWEEN THIS AGENCY AND OFFICIALS FORMERLY OR ACTIVELY REPRESENTING THE UNITED NATIONS, MILITARY INTELLIGENCE AGENCIES, AND THE N. , to a meteorologist, problematically proves Mars is much warmer than official reports stated. Thirty microns of water have been found in the atmosphere, enough to not only cause ground fog, but ALSO FROST AND SNOW!The largest crater is Stickney (visible in the photo above).The Stickney crater is 10 km in diameter, which is almost half of the average diameter of Phobos itself.As a result, scientists estimate that in the next 10-50 million years or so, it will get so low that the Martian gravity will tear Phobos into a pile of rocks.
Given their composition, size and shape, astronomers think that both of Mars’ moons were once asteroids that were captured in the distant past.
Phobos and Deimos, photographed here by the Mars Reconnaissance Orbiter, are tiny, irregularly-shaped moons that are probably strays from the main asteroid belt.

The crater is so large that scientists believe the impact came close to breaking the moon apart.
Parallel grooves and striations leading away from the crater indicate that fractures were likely formed as a result of the impact.
