It will give valuable information on how energy is transferred between Jupiter's enormous rotating magnetosphere and the large icy moons Ganymede, Callisto and Europa. RPWI will be the first-ever device to generate a 3D map of the electric fields around Jupiter. "Fantastic, after more than ten years of intensive work, we are finally ready for science discoveries!" said Jan-Erik Wahlund, principal investigator of RPWI from the Swedish Institute of Space Physics, in a statement. Altogether, these comprise seven of the 10 RPWI sensors that will measure the variations in the electric and magnetic fields around Jupiter, radio waves, and cold plasma. This week, the four Langmuir Probes and three Radio Wave Instrument antennas of the RPWI were successfully deployed. The last step has been swinging out and locking into place the probes and antennas that make up JUICE's Radio and Plasma Wave Investigation (RPWI). In the last six weeks, the flight control team has deployed all the solar panels, antennas, probes and booms tucked away safely during launch. Launched on April 13, JUICE is ESA's first-ever mission to find alien life on the icy worlds of Jupiter. ![]() The European Space Agency's (ESA) JUpiter ICy moons Explorer, or JUICE mission, is now ready to study Jupiter, said mission officials after they completed the final deployment of all instruments in the spacecraft. ![]()
