The full moon will pass in front of Mars on December 7. In astronomy, such an event is known as an occultation. In Central Texas(where I am), Mars will disappear behind the Moon at 8:58 PM and reemerge at 9:11 PM.
Occultations of bright planets by the Moon are easy to observe, and no equipment other than your eyes is required as long as the event happens at night. They're uncommon occurences: while in a typical year, the Moon occults planets several times, the frequency at a particular location on the Earth is lower. When the Moon covers the Sun instead of a planet, we call it a solar eclipse, even though it's fundamentally the same phenomenon.
