The JUICE mission

JUICE is being launch on April 13th! How to follow the Juice launch live?

The JUICE (JUpiter ICy moons Explorer) mission is the first L-class mission selected under the European Space Agency (ESA) Cosmic Vision 2015-2025 program. The launch will take place in April 2023 for an arrival in the Jupiter environment in 2031. The objectives are the exploration of the Jovian environment and the three Galilean moons: Europa, Callisto and Ganymede. A particular attention is paid to Ganymede because of its similarities with the Earth: presence of a strong magnetic field, an ionosphere and an ocean.

The MIME instrument

The MIME (Mutual Impedance MEasurement) instrument is the mutual impedance probe of  the RPWI (Radio Plasma Waves Investigation) consortium. MIME is under LPC2E responsability. The objectives of the MIME instrument are to measure the following plasma parameters: electron density, and under certain conditions temperature and electron gyro frequency. The technique used is the mutual impedance which allows access to an absolute measurement of the electron density derived from the plasma frequency on a wide band 3kHz – 3 MHz. This wide band allows access to densities of some particles per cm3 up to 10 000 per cm3. The MIME instrument makes use of two types of sensors, four Langmuir probes and three dipolar wire antennas also dedicated to high frequency waves.
