NASA’s recent Juice mission, in collaboration with ESA, achieved a groundbreaking lunar-Earth flyby, capturing the sharpest image of Earth’s radiation belts ever seen. The Jovian Energetic Neutrals and Ions (JENI) instrument unveiled the invisible swaths of charged particles surrounding Earth, setting the stage for future discoveries at Jupiter. This mission marks a pivotal moment in space exploration, shedding light on the mysteries of planetary magnetospheres and plasma heating.

What The Heck Are Earth’s Radiation Belts?
Juice mission is the most costly project ever undertaken in space NASA/ESA During a highrisk lunar-Earth flyby the JENI instrument returned some of the best Earthstrip images ever obtained, including detailed imagery showing belts of energized particles surrounding our planet. New scientific questions in planetary magnetospheres, and plasma physics interactions with atmospheric and satellite gases, will all be answered thanks to the advanced technology now being used on these missions. This is a big deal, and now powerful new missions will sail beyond the moons of Jupiter. JENI produced detailed images that showed what really happened in Earth’s magnetic field, helping reveal its extent entities.
Digital Trends
The successful flyby by Juice, and the data collection its instruments – like JENI – will undertake, represent a critical part of this: celebrating such milestones in understanding space environments. We also could obtain information about how the plasma heats and what particles it interacts with, since at least in this case we had JENI and JoEE instruments that worked After passing through the uneven Earth magnetosphere as well as radiation belts. These data paint a complete picture of the magnetic environment at other planets, guiding future missions to Jupiter and beyond. Using state-of-the-art technology on five spacecraft, Juice will be the first large-class mission in ESA’s Cosmic Vision program to focus on the nature of our Solar System and its appendages.
Towards New Frontiers
And as Juice is on its way to Jupiter, the effects of the Earth flyby are just a few of many that will pave the way for discoveries yet to come. The next Venus flyby in 2025 and subsequent encounters during the years of 2026 and 2029, will further facilitate our understanding of cylindrical magnetospheres and planetary bodies as well as hazardous modes of space environment. By applying gravity assists and with state-of-the-art instruments like JENI (Io) and JoEE (Europa), NASA & ESA are different to unlock the secrets of Jupiter’s worlds. The 2031 journey to Jupiter will be “unparalleled,” and a bounty of data about the gas giant moons and magnetic fields will help expand knowledge of processes in the solar system.
