#^FIRST Moon Images from ESA’s JUICE Spacecraft: What Did the Livestream Reveal?The European Space Agency’s Jupiter Icy Moons Explorer (Juice) mission just provided a captivating first glimpse of the Moon as it performed
“Double World First” Lunar-Earth flyby. Launched in April 2023, Juice is on an ambitious mission to study Jupiter’s largest icy moons – Europa, Ganymede, and Callisto- each believed to harbor vast oceans beneath their icy surfaces.
First Images from Juice
Screenshot from ESA’s livestreamJuice’s onboard monitoring cameras captured raw, black-and-white images of the Moon at a resolution of 1024 x 1024 pixels. These cameras, initially intended to check the spacecraft’s status post-launch, were used experimentally to photograph the Moon. The images, streamed live, showed a striking view of the lunar surface, albeit unprocessed. A notable feature in these images was a white dot, identified as a reflection from the spacecraft’s antenna

These images are raw and unprocessed, showcasing the direct output from Juice’s cameras. Over the next 24 hours, the ESA team will process these images to provide clearer and more detailed views of the Moon.
Why Is the JUICE Mission’s Double Gravity Assist Manoeuvre Considered a “Double World First”? What Makes This Particular Manoeuvre So Unique?
Giuseppe Sarri, project manager of JUICE mission,
shared his opinion with us:
“This is the first time ever that a spacecraft performs a double Moon-Earth gravity assist. No one did it before. Juice will first pass by the Moon on Monday (by coincidence the day of the Moon following the Greek and Roman naming of the days of the week) 19/8 at 21:16 UTC. This will give an extra push which will make the following flyby of Earth (on Tuesday 20/8 at 21:55 UTC) more effective. At this point the spacecraft will be deflected toward Venus for the gravity assist next year. This manoeuvre will allow to save a lot of propellant but it is a bit more risky than a simple one planet gravity assist: being the two flybys so close there will be no time to measure the trajectory and correct for possible errors after the Moon flyby and before the Earth flyby. It has to be right from the beginning.”Looking Ahead
As it continues its eight-year voyage to Jupiter,
Juice will perform multiple flybys of Earth and Venus to gain the necessary velocity for its mission. The spacecraft is expected to reach Jupiter in 2031, where it will conduct detailed studies of its icy moons, potentially unlocking secrets about their ability to support life.
