N° 39–2024: Media invitation: The Juice lunar-Earth flyby explained
2 August 2024
Media representatives are invited to attend an online briefing on 9 August 2024 to learn more about the Juice flyby of the Moon and Earth, foreseen for 19 and 20 August respectively. This precise manoeuvre will mark a double world first: the first ever lunar-Earth flyby and first ever double gravity assist by a spacecraft.
Juice, ESA’s mission to study Jupiter's icy moons, was launched in April 2023. It is currently on its way to Jupiter and still has seven years to go before reaching its destination. On 19 and 20 August, it will fly by the Moon and Earth in a unique braking manoeuvre. Earth will bend Juice’s trajectory through space, ‘braking’ it and redirecting it on course for a flyby of Venus in August 2025.
Mission operators have already adjusted Juice’s path to ensure that it arrives first at the Moon, then a day later at Earth, at precisely the right time, with the right speed, and travelling in the right direction. They are confident of success, but this is a risky challenge that no other space mission has ever faced before; the slightest mistake could take Juice off course and spell the end of the mission.
As Juice’s Spacecraft Operations Manager, Ignacio Tanco puts it, “It’s like passing through a very narrow corridor, very, very quickly: pushing the accelerator to the maximum when the margin at the side of the road is just millimetres.”
The lunar-Earth flyby provides a prime test environment for instrument teams to collect and analyse data from an actual surface in space, for the first time.
The Moon flyby is expected to take place on 19 August at 23:16 CEST. The Earth flyby should take place at 23:57 CEST on 20 August (nearly 25 hours later).

About the European Space Agency
The European Space Agency (ESA) provides Europe’s gateway to space.
ESA is an intergovernmental organisation, created in 1975, with the mission to shape the development of Europe’s space capability and ensure that investment in space delivers benefits to the citizens of Europe and the world.
ESA has 22 Member States: Austria, Belgium, the Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Ireland, Italy, Luxembourg, the Netherlands, Norway, Poland, Portugal, Romania, Spain, Sweden, Switzerland and the United Kingdom. Latvia, Lithuania, Slovakia and Slovenia are Associate Members.
ESA has established formal cooperation with four Member States of the EU. Canada takes part in some ESA programmes under a Cooperation Agreement.
By coordinating the financial and intellectual resources of its members, ESA can undertake programmes and activities far beyond the scope of any single European country. It is working in particular with the EU on implementing the Galileo and Copernicus programmes as well as with Eumetsat for the development of meteorological missions.
