Abstract
Juno is a spinning spacecraft in a highly eccentric polar orbit about Jupiter, with perijoves at about 5000 km above the cloud tops, and has completed 50 orbits as of April 2023.  From Juno’s unique vantage point, the Juno Microwave Radiometer (MWR) has measured the radio emission in 6 channels, at wavelengths ranging from 1.4 to 50 cm, with 100 mS sampling throughout each spin of the spacecraft, since the first science pass in August of 2016.  This data set covers the Jovian atmosphere over a wide range of latitudes, longitudes and emission angles, as well as observations of the inner radiation belts and of Ganymede and Europa.  MWR has yielded a number of results, as well as prompting new questions, related to Jupiter’s atmospheric composition and dynamics at depths as deep as 300 km, distribution of lightning, microwave reflection over the auroral region, Jovian synchrotron emission, and the ice shells of Ganymede and Europa. We will present an overview of MWR results to date.
