Kaveendri Shanika Rathnayake Europa, the smallest of Galilean Moons is one of the most remarkable bodies in the solar system. Scientists believe that this 1,940- mile-wide satellite harbors a huge ocean of liquid water beneath its icy shell. Also, in 2016 a study suggested that Europa produced 10 times more oxygen than hydrogen. Thus, the scientists have identified this icy world as one of the best spots in the solar system with the potential for life to evolve.  So exploring this icy moon in depth is essential for future investigations. To fulfil this target NASA's Jet Propulsion Laboratory in partnership with the John Hopkins University Applied Physics Laboratory has planned a mission called 'Europa Clipper' to be launched in June 2023 or 2025. It will enter an orbit around Jupiter and make dozens of close approaches to Europa. Though mission's preferred launch option is the Space Launch System (SLS), due to financial issues NASA has proposed to launch Euro
