Where’s Lucy Going? Studying Asteroid Mission Targets
Lucy, a new asteroid mission, has begun preparation to target multiple asteroids in the Trojan group near Jupiter for flybys in the late 2020s. Until that date, though, astronomers are busy preparing for the mission and trying to gather all the data on these objects that we can from Earth. Buie et. al. 2018 specifically investigates Leucus and Polymele, using their light curves to tease out information about their color, composition, orbit, and reflectivity.
