Title: Rotational Characterization of Hayabusa2 Mission Target Asteroid 1999 JU3

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) 1999 JU3 in 2018 and return a sample to Earth in 2020. However, the rotation state (period, pole, shape) of 1999 JU3 is currently poorly constrained. This is critical information for mission planning and operations. We propose to obtain high quality light curve photometry with SOAR/SOI that will have 5-15 times higher signal-to-noise than currently available data. 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.
