So, we know that Deimos is the smaller of the two moons that orbit Mars, and its much further out too. Phobos is a bit larger than Deimos, and orbits only 3,700 miles (6,000 kilometers) above the Martian surface. Both are tiny the larger, Phobos, is only 14 miles across (22 kilometers), while the smaller, Deimos, is only 8 miles (13 km), making them some of the smallest moons in the solar system.

Furthermore, there is evidence that liquid water lakes exist within the frozen outer shell of Europa. Deimos does have a much smoother appearance and fewer craters than its cousin, Phobos. The reason why objects like planets become spherical is because of their gravity, which pulls the planet out in each directly equally (or fairly equally). To avoid patches of knife-edged rocks, the mission has taken an alternative path up Mount Sharp. Sixteen scientists from the U.S., Europe, Canada, and Japan have been chosen to help future samples from the Red Planet achieve their full potential.
