Hello, Everyone!
Saturn's largest moon-Titan has always been an extremely important celestial body for exploration owing to its dense atmosphere and oceanic waters. But this is not just enough reason for the astronomers to drive scientists and astronomers to head for its exploration of Saturn's moon -Titan.
The most fascinating part is that Titan entails water circulation identical to that of our Earth; with clouds made up of Methane, rainfall occurring, and the water rushing across its surface to our awe. The surface of Titan is enriched with organic material. Therefore a dense atmosphere, possessing oceans, possessing water circulation identical to our Earth with its surface highly enriched with organic materials are all indicators hinting there could be probable signs of life. Henceforth, Titan is perfect to be explored in a quest for discovering prebiotic chemical compounds alike our primitive Earth before it flourished.
Considering all the aforementioned indicators, the United States Space agency-NASA authenticated a dragonfly rotorcraft mission to Saturn's largest moon Titan's surface as its surface is a resource of an organic compound. The budget of the mission is 3.35 bn US Dollars. The mission will commence in the year 2028.
The good part is that Dragonfly has successfully pulled through the preliminary design review requisites at the start of the year 2023 but it was compulsory to formulate an up-to-date fiscal estimate and called -on to organize it in the present fiscal estimate of NASA. This up-to-date fiscal estimate was featured and was given a green flag in Nov. 2023.
The Dragonfly mission was approved on the financial year 2025 estimate request made by the U.S. President with an expense to rise by twofold and a delay in its launch period of 2 –years from the earlier planned launch period in year 2019.
However, to cope with the time delay of 2 years in its launching the U.S. space agency NASA is poised to render a monetary backup for a heavy-lift launch vehicle to save the time in its journey to Saturn's largest moon.

Now, let us delve into the salient features of the Dragonfly mission. So let's get started.
SALIENT FEATURES OF THE DRAGONFLY MISSION:
->The 2- year mission leverages a "dual-quad copter" measuring identical to that of the car; to fly across several kilometers or we can say tens of kilometers within 1 hour which is a large distance to traverse as far as presently accessible additional helicopter going beyond our planet Earth's boundary is concerned.
->Within 2 years many hundred kilometers will be explored by the Dragonfly rotorcraft. But here is a kicker: Why NASA has chosen flying as a great means to explore Saturn's moon. It is due to the still and dense atmosphere present in Titan with a low gravity that makes up only flying a perfect means to explore the cosmic body.

Now, let us delve into the salient features of the Dragonfly mission. So let's get started.
Salient Features Of The Dragonfly Mission:-
->The 2- year mission leverages a "dual-quadcopter" measuring identical to that of the car; to fly across several kilometers or we can say tens of kilometers within 1 hour which is a large distance to traverse as far as presently accessible additional helicopter going beyond our planet Earth's boundary is concerned.

It is due to the still and dense atmosphere in Titan with a low gravity that makes only flying a perfect means to explore the cosmic body.
->The rotorcraft will conduct science measurements in the majority of the daytime on the Titan's surface regardless of it being a rotorcraft.
->Because of the foggy -atmosphere on Titan; the rotorcraft will get scarce sunlight i.e. the rotorcraft will not be able to charge itself using solar power or the sun's radiations and therefore it will leverage a radioisotope power system (RPS) as a power source to get charged.
Radioisotope power system is a power source that uses the thermal energy generated owing to the radioactive decay of the isotopes i.e. radioactive isotopes of an element.An isotope is an element possessing equal number of protons and electrons but different neutrons and they represent the same attributes as the primary element. A diverse isotope of the same element possesses an equal number of protons in their respective atomic nuclei however the number of protons varies.E.g., carbon -12 and carbon -14 are different isotopes of carbon.Radioactive/nuclear decay is the discharge of surplus subnuclei particles in the form of EM radiation or the discharge of particles from the atomic nucleus which leads to the formation of diffrent element. In RPS a radioactive power source Pu-238 is incorporated to get heat from the radioactive radiation in the radioactive decay phenomenon.
->The majority of work of transmitting data will be commenced and completed in the daytime itself which implies the rotorcraft will get ample amount of the nighttime to get it charged up.
->The Dragonfly rotorcraft is a rotorcraft –i.e. an aircraft that manuvoures across an area leveraging rotor blades and not wings which are in a traditional aircraft. These rotor blades play a vital role in generating lift by rotating over a central axis, for instance, helicopters; missioned to reach Saturn’s moon –Titan by 2034. It will traverse across numerous significant places in a quest to uncover prebiotic chemical processes that are identical to our primitive Earth before it flourished.
->The Dragonfly mission is a historic mission as it is one of its kind NASA’s mission which is about to leverage a rotorcraft or we can say an aircraft over on any celestial body.
Thus conclusively we can say that the Dragonfly mission is a landmark mission as it is one of its kind NASA’s mission which is about to leverage a rotorcraft or we can say an aircraft over on any celestial body. Not only that but uncovering Titan's mystery of its prebiotic chemical processes and figuring any signs of life is what everyone hopes for !
