Training for Astronauts Space

The "Dagwood Sandwich" Moon. Earlier models of Ganymede's oceans were based on the assumption that the existence of salt didn't change the nature of liquid very much with pressure. However, Dr. Vance and his colleagues found, through laboratory experiments, that salt does increase the density of liquids under the extreme conditions hidden deep within Ganymede and similar icy moons with subsurface bodies of water. Imagine adding table salt to a glass of water. Instead of increasing in volume, the liquid will actually shrink and become denser. The reason for this is that salt ions lure water molecules. The screaming winds could be carrying the dust raised from the dunes across great distances, contributing to the global cycle of organic dust on Titan. These would result in effects similar to those that occur on both Earth and Mars. On occasion February will have no full moons and January and March will both have two. In this case, you have two calendar blue moons in the same year. However, there can be no more than one in a year's time or it would not be that rare of an event. Using the Farmer's Almanac description there can be a maximum of one in a year.
