Discovery Channel on-line is carrying this summary of new discoveries in Martian climatology. By simply varying the axial tilt of the planet to 45 degrees (from the current 25-and-change), a team of scientists was able to model the creation of glaciers that appear to mimic the ones which left evidence on the planet long ago. No extra water was required. Since Mars does not have a large moon with which to stablize its orbit, these scientists say the planet probably regularly "wobbles off" to these extremes at random times.
