P012:
Exploration of the Jupiter Trojans





Session ID#: 23834

Session Description:
Exploration of the Trojans has reached a critical phase with new missions and observational tools.  Lucy, just selected by NASA as the next Discovery mission, will launch in 2021 on a trajectory that will encounter six Jupiter Trojans with a diverse range of properties. An innovative solar-sail-based mission to directly sample a Trojan is currently under consideration by JAXA. Earth-based studies are revealing new complexity among the Trojans including new collisional families and an excess of slow rotators. LSST will greatly expand the number of known Trojans and JWST will enable mid-infrared spectroscopic studies of water and organics. The connection to other populations including transneptunian objects, Centaurs, and irregular satellites is being studied with Earth-based photometry and spectroscopy and with laboratory investigations of possible surface components. This session will bring together researchers working on different aspects of Trojan studies to share their new results.
