NASA Scientist for a day


When the teacher was explaining about the planets, all of sudden a question clicked in my mind that if there is any planet name which starts with the same letter of my name. Wow!! Got it. It is Saturn. As we know that the Saturn has many moons. One of them, is known as the "Enceladus" –Greek name. It is a small ocean world which is covered in ice, makes it very attractive. The 6th   largest moon of Saturn has geysers spewing water vapor. The covering in water ice makes it alluring. The southern region of the Enceladus has geysers. There are few stripes known as the "tiger stripes' from which geysers come. These stripes looks like cracks and acing like vents. A probe "Cassini" which was launched in 1997 & entered orbit in 2004 by NASA. It was there almost 13 years. It took many photos and videos. The Enceladus attracts attention due to be one of the brightest objects in the entire solar system because it reflects almost 100% of the light. However, sometimes there are large variations in plume brightness. The water plumes (Mix of salty water ice, organic material and vapor) are so fascinating and make us enthusiastic to know more and more. There are pressurized subsurface chambers from which the plumes emanate. Many scientists and engineers are working on another probe. This probe they are trying to send in 2020 (Proposed) that will make at least 7 flybys of Enceladus. Hope that resolution mass spectrometer to help us to know how they are made.  They are thinking that there may be indications of life. Chances have been seen. There are researches still going on. Hope that the next probe will be successful in its mission. There are still questions for the scientists roaming around. A liquid ocean and ice beneath the Enceladus is throwing out the water? Scientists have discovered that the Enceladus can have three ingredients  of survival for living organisms. These are the water, chemistry and organic. But the most interesting part of this is that the Enceladus has geysers coming only from the southern pole or southern region of the Enceladus.
