Title: Rotational Characterization of Hayabusa2 Mission Target Asteroid Ryugu

Abstract: In June of 2010 the Japanese Space Agency's Hayabusa mission successfully completed the first ever sample return from an asteroid. Following on the success of this mission, Hayabusa2 is scheduled to rendezvous with the asteroid (162173) Ryugu in 2018 and return a sample to Earth in 2020. However, the rotation state (period, pole, shape) of Ryugu is at present poorly constrained. This is critical information for mission planning and operations. We propose to obtain high signal- to-noise light curve photometry with SOAR/SOI. These observations will span a wide range of viewing aspects and in combination with existing and other planned observations will result in new shape and pole solutions. These SOAR observations will be part of a larger ground- based campaign in 2016 and 2017 to fully characterize this important mission target ahead of the spacecraft's arrival in 2018. Ultimately, through comparison to in situ observations obtained by the spacecraft, these data will serve as a validation of ground based observational techniques. These observations are part of a NASA-funded Hayabusa2 participating scientist program and are a continuation of a previously awarded SOAR program that began in 2016A.
