In a critical maneuver that had space experts on edge, the European Space Agency’s (ESA) Jupiter probe, “Juice,” successfully completed its first-ever flybys of the Moon and Earth within 24 hours. These maneuvers, essential for the spacecraft’s mission to Jupiter, involved a precise trajectory that harnessed the gravitational forces of both celestial bodies. The ESA reported that the flybys not only went according to plan but also surpassed expectations.

Utilizing Gravity for a Mission Boost
The primary goal of the flybys was to alter “Juice’s” trajectory, leveraging the gravitational pull of the Moon and Earth to adjust the spacecraft’s speed and direction. This maneuver was pivotal, as it allowed the mission to save between 100 and 150 kilograms of fuel. This fuel efficiency could enable “Juice” to get closer to Jupiter’s moon Ganymede than initially planned, or potentially extend the mission’s duration beyond its scheduled end in 2035.
A Smooth Operation Exceeding Expectations
The flybys were closely monitored from ESA’s control center in Darmstadt, Germany. “Juice” flew at an altitude of just 6,840 kilometers over Southeast Asia and the Pacific Ocean, capturing images and collecting scientific data with eight of its ten instruments. According to Simon Plum, head of the control center, the maneuver went “better than planned,” showcasing the precision and expertise involved in this challenging operation.
Strategic Flybys Set the Stage for Further Exploration
The dual flybys were not just about fuel savings; they also provided a unique opportunity to study “Juice’s” instruments in action. The timing and location of these flybys allowed ESA scientists to thoroughly analyze the spacecraft’s performance in preparation for its long journey to Jupiter. This successful test is a promising sign for the mission’s future as “Juice” heads toward Venus and, eventually, the gas giant.
Looking Ahead to Jupiter’s Icy Moons
Launched with the goal of exploring Jupiter’s moons—Europa, Callisto, and Ganymede—”Juice” is expected to reach the gas giant by 2031. Scientists believe these moons harbor vast oceans beneath their icy surfaces, potentially creating conditions suitable for life. The mission, which is set to run until at least 2035, aims to gather detailed data that could reshape our understanding of these distant worlds.
