Summary

In December 2014, the Japanese spacecraft Hayabusa2 began its more than 2 billion miles journey to rendezvous and land on a rocky body with a diameter of no more than a kilometer. It arrived in June 2018, and on pages 272, 268, and 252 of this issue, the first observations of Hayabusa2's remote sensing instruments are reported by Kitazato et al. (1), Watanabe et al.

Designed to probe the geology, morphology, and composition of the asteroid, this mission will help clarify the formation of the solar system 4.5 billion years ago (see the figure).
