Japan's lunar probe SLIM (Smart Lander for Investigating Moon) is apparently still scheduled to land today in about three hours, which I assume means the lander is pretty much committed at this point. This one is interesting because it's an autonomous effort. That is, the lander itself will decide exactly where to land, with no human involvement. Other than that, as far as I can tell it's not all that an exciting a mission since the lander is very small and the "rover" is more like a hopping toy. If the mission is successful, however, Japan will become the 5th country to soft land on the surface of the Moon.
