2020-21 India Winner, Grade 5-6 - Topic: Titania
Once Voyager 2 flew by Uranus, it could only get one side of all of them. Doesn't one wonder what's on the opposite side? I do, and that is why I'm writing this essay. So let's start with the primary thing:
Why is Titania so interesting to research?
Titania, or "Uranus III," is Uranus' largest moon at 1,578 kilometers. Herschel, the German astronomer, discovered Titania in 1787. It has a system of fault valleys, several of them 1600 kilometers long! It probably features a rocky core and an icy mantle. There could be liquid water near the core-mantle boundary. It's considerably dark & vaguely reddish in color. After two centuries of Titania's unearthing, Voyager 2 made its momentous flyby, taking pictures. The images divulged that Titania is topographically active. All this might be tons, and that is only on one side! Imagine what might be there on the other.
What could there be on the opposite side?
Likely there'll be more fault valleys and craters, but there may be more. If the mantle contains ammonia, it would become an antifreeze and allow mushily or liquid water. If this is true, then there would be a greater probability of an ocean between the core mantle frontier. If it exists, scientists evaluate that the ocean depth would be around 50 km. The water won't be fit for use, but with some tinkering, it may work. That's one reason to observe the opposite side. Another is that organic compounds may be present in the moon's core or rocky parts. Some of them can be satisfactory to buttress life. We can send a rover to scrutinise and pinpoint if these are beneficial. Unfortunately, Titania doesn't have any atmosphere or magnetosphere. So, regulation of experiments is not going to be feasible.
