I think that my fave mystery on the list is the one regarding the similarity between the atmosphere on Titan and that of Earth (and that its the only moon in the solar system with an atmosphere).

OR The Tungusta Event....love a good mystery. Statistics and science have not yet been able to give an absolute answer...

Okay that's 2 favorites. Never mind.:D
