The Cassini-Huygens exploration of Saturn Ben Zobrist Jersey , a seven-year joint venture of NASA, the European Space Agency Kris Bryant Jersey , and the Italian Space Agency, is realizing more surprising discoveries. The Cassini space probe achieved its closest approach of any Saturn moon with a 109 mile orbit of one of the most innermost moons of Saturn Kyle Schwarber Jersey , Enceladus on November 26, 2005.


Enceladus is a small moon of 314 miles across that is so bright it reflects nearly one hundred percent of its heat. For this reason Yu Darvish Jersey , it is a very cold moon, with a temperature of minus 330 degrees Fahrenheit. Its orbit is influenced under the large gravitational pull of Saturn as well as the gravitational influence of large nearby moons Tethys and Dione. Previous voyages by Voyager as well as Cassini have shown it to have at least five different geological terrains across its small surface.


What was discovered that makes Enceladus so unique for such a cold moon is that unlike nearby moon Mimas Javier Baez Jersey , which is basically a completely dead moon, Enceladus is currently geologically active. An emission of water vapor and minute ice particles from its south pole from some sort of internal heat source on Enceladus has been confirmed. The cause of the tremendous heat source that must be present to heat the ice of such a cold moon to emit such a plume of ice and water vapor into the atmosphere is unkown. On its nearest approach to Enceladus of 109 miles Ryne Sandberg Jersey , Cassini was able to use infrared detection to prove the existence of this column of ice into the atmosphere and beyond.


Saturn's E ring is the broadest and faintest of any of Saturn's rings. It is composed of fine ice particles of 2.9 microns in average size. The average size of Cassini's emissions is 10 microns. The tiniest particles escaping from Enceladus are the source of the composition of Saturn's E ring. This was a major discovery in itself.


Cassini confirmed that the heat sources are coming from geological phenomena known as the tiger stripes of Enceladus. The tiger stripes are parallel fissures running down the planet approximately eighty miles long and separated by twenty-five miles on average. They seem to be extremely geologically young being of between 10 and 1000 years old. At their southern end Cassini detected the large emanations of heat that are responsible for the ice particle ejections.


The cause of the internal heating remains the big mystery. It is surmised that it is due to tidal activity or possibly radioactive phenomena. This riddle regarding Enceladus is not yet understood as of today. Enceladus is one of the rare geologically active moons found so far in the solar system along with Jupiter's Io and Neptune's moon Triton.


More light will be shed on Enceladus in March of 2008 when Cassini revisits Enceladus.

Self Storage Options Considerations to Consider

There are a lot of self storage places that offer different features. Which self storage unit you choose should be the one that is best suited for your needs. There are a lot of self storage places that offer different features. Which self storage unit you choose should be the one that is best suited for your needs.

Issues of a self storage unit:

The most important consideration in choosing a storage unit is what it is going to hold in storage for you. If you are going to store wine and alcohol you should make sure the storage company allows you to do so. There are some restricted items many storage companies will not let you store.

In the case of wine you may want to consider a storage unit that specializes in wine and liquor storage. The place where they are stored must be climate controlled or else the wine corks may dry out. If not stored properly, champagne may explode. If not climate controlled to a very exact temperature the wine may age too fast. Even liquor is not meant to be stored in high heat or to endure prolonged freezing temperatures. True Ernie Banks Jersey , cases of wine or liquor long buried in the ocean do survive but they are actually in a very climate controlled atmosphere with pressure being exerted on the cases all of the time. And they are never disturbed except when they are discovered.

Some places may consider the storage of wine to be a bonded storage which means it is exempt from tax until removed and shipped to the ultimate buyer. If this is your own wine you are storing you do not want that type of wine storage unit.

If you insist in storing wine in a non-climate controlled storage facility then you take the risk of it being ruined and you may as well no.
