Time for us to answer the big question: why has no one ever attempted a lunar-Earth flyby before?👉

On 19 and 20 August,

will fly by Earth and Moon in a unique braking manoeuvre. Earth will 'bend' Juice’s trajectory through space, braking and redirecting it on course for a flyby of Venus in August 2025.

We'll give you a wave as we go past! 👋

To send

straight to Jupiter would have required an impossible amount of propellant.
So instead, Juice is taking the scenic route, using the gravity of the Moon, Earth and Venus to adjust its course.
The first flyby is due on 19–20 August👇
