The Uranian magnetic field is more expansive than previously thought, according to newly analyzed data from Voyager 2, making it easier to search for moons with oceans.
The Planetary Plasma Environments group (PPE) has a strong heritage in the exploration of planetary magnetospheres and space plasma interactions throughout the solar system. It has contributed instruments to several past missions that flew-by or orbited Jupiter (Galileo, Cassini, Ulysses). The PPE participates in the JUICE mission by contributing hardware and scientific expertise to the Particle Environment Package (PEP).
The MPS instruments on board ESA’s JUICE spacecraft have successfully completed their commissioning in space - and delivered their first observational data.
The launch was successful; the ESA’s space probe JUICE is now on its way to the Jupiter system. There, it will primarily study the gas giant's icy moons.
ESA's space probe is on the move: First it heads for the launch site in Kourou - and in April it will begin its long journey to Jupiter and its icy moons.
