"The heavenly body have held the mankind entranced since time immemorial. It has always grabbed our fantasies. The magnificent and challenging space seems mysterious and magical. Looking at the moon has always induced me with an unusual dose of imagination and vision. It has always been intriguing, thrilling and exciting for me. In the rashness of space and immensity of time, I have chosen the "Target 2" (Dione) because it seems exciting and the mystery of its name drew me in. The name 'Moons of Saturn' grabbed my attention. This moon is also called "ICE MOON" which made me all the more interested in it.


Sitting beside the window one night
I saw the moon's decorous light
Even at such a great height
I could see that it was bright
At that time of night, It was such a delight
The way it caught my sight

'MOON' the symbol of beauty – sincerity – purity – deepness – loyality – creativity and philosophy, has always been a topic of great interest. Here it wouldn't be false to say that space is mind staggering. The planet of Saturn was first discovered by Giovanni Cassini on 21th March, 1684. Dione is an interesting moon because of its general geographical information. The fact that Dione seems to spun exactly 180 degrees is a mystery.

Dione is a small moon of 1,123 km (698 miles) in diameter orbiting Saturn every 2.7 earth days at a distance of 377,400km (234,000 miles), roughly the same distance that the moon orbits around the sun. I like the Target 2 (Dione) because it is interesting to study. The orbital period of Dione is 66 hrs, Its mean radius is 561.7 km, its volume is 742,338,322 km3 and the orbit size is 377,415 km.

Dione is faced – locked with its parent; one side always faces towards Saturn. Dione is in resonance with two neighbor moons, Mimas and Enceladus. These moons speed up when comes near to Dione and slows down as they draw away.

The interesting fact about Dione, which draw me towards itself is that Dione is made of a dense core of silicate rock with remainder of its material being ICE. At Dione's average temperature i-e 121 degrees Fahrenheit (-1860 C and 87K), ice is very hard and behaves like rock. Very fine ice powder (equivalent to cigarette smoke) from Saturn's E-ring constantly bombards Dione.

The most interesting information about Dione which just grabbed my attention is that it is a plain moon of Saturn which may have once had a geologically active subsurface ocean. Subsurface oceans are thought to exists on several bodies in solar system, including Saturn's moon Enceladus and Titan and Jupiter's Moon Europa. If Dione turned out to have a liquid layer under its crust, that would increase the moon's chances of supporting life.

Interesting features of Dione include heavenly created terran which craters as large as 100 km (62 miles) across, moderately cratered plains, lightly cratered planes and fractured areas.

The luster of this moon has always caused my eyes to sparkle. My thoughtfulness is evoked by it. Therefore, I firmly believe that the cameras must be turned to the Dione as it gives an overhead view and high resolution cameras must be used. "
