Good morning, Rallypoint. Today's Astronomy Picture of the Day (APOD) is titled "Martian Moon Phobos from Mars Express." Mars Express is a European Space Agency (ESA) venture, and was launched in June 2003. It has been in orbit around Mars since December 2003, and is currently expected to be decommissioned in 2022. One key discovery is the presence of a subglacial lake (of water) in 2018. This lake is similar to Lake Vostok in Antarctica.
This image of Phobos was captured by Mars Express in 2010. The unusual orbit and color of this Martian moon indicates that it may be a captured asteroid composed of a mixture of ice and dark rock. Phobos gets closer to Mars by about one inch every year, 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.

APOD Background
"Explanation: Why is Phobos so dark? Phobos, the largest and innermost of two Martian moons, is the darkest moon in the entire Solar System. Its unusual orbit and color indicate that it may be a captured asteroid composed of a mixture of ice and dark rock. The featured picture of Phobos near the limb of Mars was captured in 2010 by the robot spacecraft Mars Express currently orbiting Mars. Phobos is a heavily cratered and barren moon, with its largest crater located on the far side. From images like this, Phobos has been determined to be covered by perhaps a meter of loose dust. Phobos orbits so close to Mars that from some places it would appear to rise and set twice a day, but from other places it would not be visible at all. Phobos' orbit around Mars is continually decaying -- it will likely break up with pieces crashing to the Martian surface in about 50 million years."
