Jam packed issues filled with the latest cutting-edge research, technology and theories delivered in an entertaining and visually stunning way, aiming to educate and inspire readers of all agesThe Jupiter Icy Moons Explorer, or JUICE, is a European Space Agency mission to explore Jupiter and three of its icy moons: Europa, Callisto and Ganymede.
Still, many questions about Jupiter and its moons remain unanswered, especially those regarding the potential of some of those bodies to host life. Together, JUICE and Europa Clipper are set to deepen our understanding of the Jupiter system and perhaps pave the way for a future mission to land on Europa.
Among JUICE's instruments are cameras, sensors for analyzing the chemical composition of the moons' ice crusts and their surrounding environments, magnetometers, and radar that will create detailed maps of the moons' surfaces and, for the first time, peer beneath them. "The moons are changing shape over time due to the gravity of Jupiter," Witasse said."The elevation of the surface changes with time, and we can detect this. The amount of elevation depends on what's inside the moon. If the icy crust is floating above liquid, the tides will be much bigger than if everything inside the moon is solid.
ESA hopes data from JUICE will help scientists understand what maintains the visible light and dark bands in Jupiter's atmosphere, which are known to differ in opacity and spread from the equator toward the poles. The probe will also study processes in the planet's middle and upper atmosphere, which extends beyond the visible clouds.
"Europa is closer to Jupiter; there is more gravitational attraction from Jupiter, so the tides are much larger," Witasse said."There is more heating inside the moon; the moon is much more active than Ganymede. And when you search for life, it's better to search in active places.
