This GIF, made up of images from the Juice monitoring camera, shows the fourth Langmuir Probe deploying. Between 22 and 26 May 2023, the four Langmuir Probes and three Radio Wave Instrument antennas of the Radio & Plasma Wave Investigation (RPWI) were successfully deployed. Altogether these make up seven of the 10 RPWI sensors that will measure the variations in the electric and magnetic fields around Jupiter, as well as radio waves and cold plasma.
About Juice
Juice is humankind’s next bold mission to the outer Solar System. After an eight-year journey to Jupiter, it will make detailed observations of the gas giant and its three large ocean-bearing moons: Ganymede, Callisto and Europa. This ambitious mission will characterise these moons with a powerful suite of remote sensing, geophysical and in situ instruments to discover more about these compelling destinations as potential habitats for past or present life. Juice will monitor Jupiter’s complex magnetic, radiation and plasma environment in depth and its interplay with the moons, studying the Jupiter system as an archetype for gas giant systems across the Universe.
