Europe’s JUICE Jupiter probe recently made a historic lunar flyby on August 19, 2024, capturing stunning photos of the moon during the encounter. The JUICE spacecraft, short for Jupiter Icy Moons Explorer, came within a mere 465 miles (750 kilometers) of the lunar surface, marking the first leg of an unprecedented gravity-assist doubleheader. The second leg of this journey will occur on Tuesday evening when the probe flies by Earth.
The European Space Agency (ESA) shared the images captured by JUICE during the lunar encounter, showcasing the moon in all its glory. The photos were taken using the probe’s two onboard monitoring cameras, which were specifically designed to confirm the deployment of the solar arrays and scientific instruments. The raw and unprocessed images were shared with the world through a live webcast that included commentary from members of the JUICE team.
JUICE, which launched in April 2023, is on a mission to study Jupiter and three of its four big Galilean moons: Ganymede, Callisto, and Europa. These moons are believed to harbor oceans of liquid water beneath their icy shells, with Europa’s ocean likely in contact with a rocky seafloor, allowing for various chemical reactions. The moon and Earth flybys conducted by JUICE this week are historic, as no other mission has ever performed a double gravity assist. These maneuvers will set the probe on course for a similar encounter with Venus in August 2025, which will propel JUICE towards the giant planet.
The flybys serve as a braking maneuver for JUICE, saving valuable time and propellant for the mission. Ignacio Tanco, JUICE spacecraft operations manager, explained that by following the sequence of Earth and Venus flybys, the team can arrive at Jupiter around July 2031 with the shortest possible cruise phase. The innovative approach of braking first results in significant time savings compared to using engine burns to achieve the same change in velocity.
During the Earth flyby on Tuesday, JUICE will come within a mere 4,250 miles (6,840 km) of Earth, with the closest approach expected over the North Pacific Ocean. While amateur astronomers in Alaska or other locations around the North Pacific may be able to observe the probe through a telescope during the encounter, there will not be a live webcast of the event. Due to telemetry-receiving stations being located in the Southern Hemisphere, the JUICE team will be unable to communicate with the probe during the Earth flyby.

The Significance of the JUICE Mission
The JUICE mission holds immense significance in the realm of space exploration, particularly in the study of Jupiter and its fascinating moons. By focusing on Ganymede, Callisto, and Europa, JUICE aims to unravel the mysteries of these icy worlds and potentially uncover clues about the existence of extraterrestrial life. The presence of liquid water oceans beneath the icy surfaces of these moons presents a unique opportunity to explore environments that could harbor life beyond Earth.
The JUICE spacecraft is equipped with advanced instruments and cameras that will enable scientists to study the composition, geology, and potential habitability of Jupiter’s moons in unprecedented detail. The data collected during the mission will not only enhance our understanding of these distant worlds but also provide valuable insights into the formation and evolution of planetary systems.
Innovative Maneuvers for Efficiency
One of the most innovative aspects of the JUICE mission is its use of gravity-assist maneuvers to optimize the spacecraft’s trajectory and conserve propellant. By utilizing the gravitational pull of celestial bodies such as the moon, Earth, and Venus, JUICE can adjust its speed and direction without expending large amounts of fuel. This strategic approach allows the mission to reach its destination in a more efficient and cost-effective manner.
The recent lunar flyby conducted by JUICE demonstrates the precision and expertise of the mission team in navigating the spacecraft through complex maneuvers in space. By coming within close proximity to the moon and Earth, JUICE is able to harness the gravitational forces of these bodies to propel itself towards Jupiter. This unique approach not only accelerates the spacecraft’s journey but also minimizes the risks associated with traditional propulsion methods.
Potential for Discoveries in the Jupiter System
As JUICE continues its voyage towards Jupiter, the scientific community eagerly anticipates the wealth of discoveries that await within the gas giant’s system. The exploration of Ganymede, Callisto, and Europa holds the promise of uncovering new insights into the conditions necessary for life to thrive beyond Earth. The presence of liquid water oceans on these moons opens up a realm of possibilities for studying unique environments that could support microbial life or other forms of organisms.
The data collected by JUICE during its mission will be instrumental in advancing our understanding of the processes that shape planetary bodies and influence the development of habitable environments. By studying the geology, chemistry, and dynamics of Jupiter’s moons, scientists hope to shed light on the origins of the solar system and the potential for life elsewhere in the universe. The JUICE mission represents a significant step forward in the exploration of our cosmic neighborhood and the search for life beyond Earth.
In conclusion, the JUICE Jupiter probe’s recent lunar flyby marks a remarkable achievement in space exploration, showcasing the ingenuity and determination of the mission team to unravel the mysteries of the solar system. The stunning photos captured during the encounter provide a glimpse into the beauty and complexity of the moon, setting the stage for further discoveries as JUICE continues its journey towards Jupiter. As the spacecraft prepares for its upcoming Earth flyby and subsequent encounter with Venus, the scientific community eagerly awaits the groundbreaking insights that will be gained from this ambitious mission.
