ESA is kicking off the new year by inviting you to create a unique juice mocktail to represent the JUpiter ICy moons Explorer – also known as Juice – launching in April. The winner of the most imaginative recipe will be invited to ESA’s Social Space launch event in Darmstadt, Germany, where our favourite space juices will be served!

Full rules and how to enter below

Juice the mission will be exploring gas giant Jupiter and its three large ocean moons: Europa, Ganymede and Callisto. One of its key goals is to understand if the oceans of these icy moons could have ever been suitable habitats for life.

The spacecraft will launch on an Ariane 5 in April 2023 on an eight-year journey including gravity assist flybys of Earth and Venus before arriving in the Jupiter system in 2031. It will orbit Jupiter and make 35 flybys of the three large moons before switching orbits in a space exploration first to make a daring and unique study of Ganymede from orbit.

Whether you take inspiration from the creamy swirls of Jupiter’s atmosphere, from the layered structure of the ice moons, or from the challenging operations needed to fly to and around the extreme space environment of the Jupiter system, we look forward to seeing how the mission whets your appetite for creating a tasty #SpaceJuice recipe!
