Oxygen Envelopes Saturn's Icy Moon

The article above discusses the recent discovery of a thin layer of oxygen that surrounds one of the icy moon's, Dione, orbiting Saturn. Even though Dione would most likely not have the ability to support life at this point in time, through further warming of the Solar System it may one day become an Earth like body. Since the time span necessary for this type of atmosphere to develop is quite long, scientists are looking to other moons orbiting the gaseous planet to satisfy their search for an Earth like planet. Thus far, Enceladus, the sister moon of Dione, is said to have a liquid ocean beneath its icy surface. Looking at the developments of the moons of gaseous planets, everyone should be excited to hear that some day many of the moons surrounding Saturn could turn out to share features with the Earth, and with some adaptation of our species, we could relocate ourselves when danger overcomes the Earth, or we may even witness new life appear on these moons as they develop. While these types of advancements may not help us now, they may provide security to future generations of humans as the generations leading up to them do not make sustainability of the Earth and its resources a priority.

It is very exciting to know that there may be another planet out there that may one day be able to support human life, providing a place for future generations to live when Earth's sustainability runs out. In the article, not only did Saturn's moons show liquid oceans and the ingredients for life, but Jupiter, another gas giant, has moons with similar characteristics. Although this would be a great alternative planet for humans, what would be the consequences of living there when it is full able to support life. The effects of space on humans health can be detrimental alone, causing loss of bone density as well as muscle wasteage, and new research even shows eye damage, what health problems could rise by living on one of Saturn's or Jupiter's moons?
Aside from creating a new potential planet for humans, future generations may be able to unravel some of lifes greatest secrets by watching the development of these moons. As the solar systems heats and the moons turn into an Earth like body, future generations may be able to study and understand the creation and evolution of our Earth. As Cassidy mentioned, new life could appear on these moons as well.
As NASA and the European Space Agency continue to study the moons around gaseous planets it will be interesting to see the potential they have and what new advancements can be made because of them.
