SDAA Speaker SDAA Speaker

Dr. Steven Levin is a Juno Project Scientist at the Jet Propulsion Laboratory. His research interests include: Measurements of the spatial power spectrum, frequency spectrum, and polarization of the Cosmic Microwave Background Radiation. Search for ExtraTerrestrial Intelligence (SETI) by surveying for narrow-band microwave emission. Measurements of magnetic fields in pre-protostellar cold molecular cloud cores by observation of the Zeeman effect in CCS. Modeling of the inner Jovian radiation belts based on analysis and observations of the associated synchrotron emission.

Juno is in 53-day polar orbits, observing Jupiter in order to understand the planet’s gross size and structural properties, as well as measuring its atmospheric composition, temperature and deep wind profiles.
