What's happened
The European Space Agency's Jupiter Icy Moons Explorer (Juice) successfully executed a historic fly-by of Earth on August 20, 2024, using gravity assists from both the Moon and Earth. This maneuver is part of its journey to Jupiter, expected to take over eight years, and aims to save fuel for scientific investigations of Jupiter's moons.
What's behind the headline?
Mission Significance
- Fuel Efficiency: The gravity assist technique will save 100-150 kg of fuel, allowing for extended scientific operations upon reaching Jupiter.
- Scientific Preparation: Early fly-bys enable calibration of scientific instruments, enhancing data collection capabilities.
Future Implications

What the papers say
According to The Independent, the Juice spacecraft's fly-by was described as 'flawless' by Ignacio Tanco, ESA's spacecraft operations manager, emphasizing the precision required for such maneuvers. The successful execution of this double fly-by is a significant milestone, as noted by ESA director general Josef Aschbacher, who remarked on the journey's worthiness alongside its destination. Sky News highlighted the risks involved, noting that even minor errors could jeopardize the mission, underscoring the high stakes of space exploration. The Independent also reported on the stunning images captured during the fly-bys, showcasing real color differences on the lunar surface, which adds a visual dimension to the mission's scientific objectives.
How we got here
Launched in April 2023, Juice is on a 4.1 billion-mile mission to explore Jupiter's moons—Callisto, Europa, and Ganymede. The spacecraft's recent fly-by marks the first time a spacecraft has used both the Moon's and Earth's gravity for a double assist.
