On 13 April 2023 ESA’s JUICE mission is due to launch at 12:15 UTC / 13:15 BST / 14:15 CEST from Europe’s Spaceport in French Guiana.

When it launches, the Jupiter Icy Moons Explorer will be 8 eight years from its final destination.

The mission is preparing to explore Jupiter, the largest planet in the Solar System, and its icy Galilean moons Europa, Ganymede and Callisto.

These moons are thought to host subsurface oceans, meaning they are prime locations in the Solar System to search for habitable conditions and the signs of life.

JUICE will swoop past Callisto, Ganymede and Europa before inserting into orbit around Ganymede in 2034.
