How to follow the Juice launch live

All times CEST. Times subject to change at short notice

An ESA press release will be issued upon successful solar array deployment, at approximately 16:00 CEST.

Over the two and a half weeks following launch, Juice will deploy its various antennas and instrument booms, which will be reported on Twitter by @ESA_JUICE and @esaoperations in the first instance. An intense three-month commissioning of Juice’s scientific instruments will also follow.

The first of four gravity assist flybys in the inner Solar System will take place in August 2024 with a lunar-Earth gravity-assist – a flyby of the Moon followed 1.5 days later by one of Earth.

ESA’s Jupiter Icy Moons Explorer, ‘Juice’, is humankind’s next bold mission to the outer Solar System. It will make detailed observations of gas giant Jupiter and its three large ocean-bearing moons – Ganymede, Callisto and Europa. This ambitious mission will characterise these moons with a powerful suite of remote sensing, geophysical and in situ instruments to discover more about these compelling destinations as potential habitats for past or present life. Juice will monitor Jupiter’s complex magnetic, radiation and plasma environment in depth and its interplay with the moons, studying the Jupiter system as an archetype for gas giant systems across the Universe.

Juice launches on an Ariane 5 from Europe’s Spaceport in Kourou in April 2023. It has an eight-year cruise with flybys of Earth and Venus to slingshot it to Jupiter. It will make 35 flybys of the three large moons while orbiting Jupiter, before changing orbits to Ganymede.

Juice is a mission under ESA leadership with contributions from NASA, JAXA and the Israel Space Agency. It is the first Large-class mission in ESA’s Cosmic Vision programme.
