Because Jupiter is a gas planet, it is constant changing and therefore it has been interesting to see the type of data collected, expanding our understanding of our Solar System. For example, Jupiter’s’ icy moon Europa is one of the most fascinating aspects of the exploration. One of the four moons orbiting Jupiter, it is the sixth largest moon in the Solar System.
First explored in 1973 and 1974, the two Voyager probes were able to provide the most detailed photographs of the moon’s icy surface. The photographs caused many scientists to speculate about the possibility of a liquid ocean – and even life – underneath. If life or evidence of life was discovered on the icy moon, it wouldn't be on the surface but instead it would be hidden in the depths of the oceans, where it is warmer and the pull of a nearby planet's gravity keeps water liquid.
Juno is the second spacecraft to orbit Jupiter after the nuclear powered Gailileo. Unlike earlier spacecraft, the Juno Probe is powered by solar energy, commonly used by satellites orbiting Earth. Juno also categorizes storms and pressure ridges that form on Jupiter has helped scientists understand the persistent high-pressure region in the atmosphere of Jupiter known as the Great Red Spot. It is a weather storm called an anticyclone which is wind that flows in the opposite direction of a low-pressure region. It is the largest in the Solar System and has been continuously observed since 1830.
In order to tackle Jupiter’s mysteries, the spacecraft, its instruments and its managers are all building on technology and strategies by previous missions which will give us a better understanding of where we came from and how the Solar System was formed.
