It was the Hayabusa's 7 years old birthday yesterday.
TCM-1 was successfully performed between May 1st and May 4th, last week.
The distance to the Earth seems to have been reduced not so much.
This is true. The purpose of TCM-1 was to control the instance of flying by Australia.
With the combination with TCM-2, the vectorized and synthesized delta-V constitute the
aimed delta-V toward the Sun. There is a strict attitude constraint imposed on the
spacecraft. The attached figures comprehensively provide the essence of this operation.
This week, Hayabusa will reduce the wheel speed that has accumulated the
solar radiation disturbance. And the precise orbit determination will be performed for
TCM-2 after that.
