The position you see here is based on my location in Indiana. In South America the moon will actually move in front of Mars. This is known as an occultation, e.g. the moon will "occult" Mars.
Every time I poke around in Stellarium I find new and interesting events. I suppose I could have just looked at the 101 Astronomical Events for 2014, but stumbling upon conjunctions is fun too.
