The asteroid explorer "Hayabusa" is flying smoothly toward the asteroid "Itokawa" and is
expected to arrive in mid September.
We have already released a photo of the Itokawa taken by the Hayabusa onboard star
tracker on August 15, but another onboard camera, the thin optical navigation camera
(ONC-T) also successfully took a photo.
Photos taken on Aug. 23 and Aug. 24 are superimposed so that you can see the movement
in comparison with a fixed star in the back.
The distance between the Hayabusa and the Itokawa at the time of the photo was less
than 10,000 km, and it is about 330 million kilometers from earth.

Circles are Itokawa Images taken by Telescopic Optical Navigation Camera(ONC-T).
Solid lines are Itokawa Ioci predicted seen from Hayabusa.They were correctly
updated,so that the 8/23 images could be on the predict.
