TOKYO (JAXA PR) — On June 3, 2018, ion engine operation was completed and the final approach to the asteroid begun. By photographing the asteroid with the Optical Navigation Camera, optical navigation (precisely “hybrid navigation using optical and radiometric observations”) can be used to approach Ryugu while accurately estimating the trajectory of the spacecraft and asteroid.

TOKYO, March 1, 2018 (JAXA PR) — On February 26, 2018, Hayabusa2 saw its destination -asteroid Ryugu- for the first time! The photographs were captured by the ONC-T (Optical Navigation Camera – Telescopic) onboard the spacecraft. Images were taken on February 26th.

The distance between Ryugu and Hayabusa2 when the images were taken is about 1.3 million km. Ryugu as seen from Hayabusa2 is in the direction of the constellation Pisces.

“Now that we see Ryugu, the Hayabusa2 project has shifted to the final preparation stage for arrival at the asteroid. There are no problems with the route towards Ryugu or the performance of the spacecraft, and we will be proceeding with maximum thrust,” explains Project Manager, Yuichi Tsuda.

The ONC-T was developed under collaboration between JAXA, the University of Tokyo, Kochi University, Rikkyo University, Nagoya University, Chiba Institute of Technology, Meiji University, The University of Aizu, the National Institute of Advanced Industrial Science and Technology (AIST).
