Flyingの用法
Developing an autonomous navigation system was another goal. It takes a radio signal 16 minutes to travel 300 million kilometers between the Earth an Itokawa.
In an emergency, Hayabusa could not wait for commands. It had to judge the situation and decide what to do on its own.
The other two goals were even more difficult. Itokawa is a small peanut-shaped asteroid only 535 meters long.
Flying at the speed of 34 kilometers per second, Hayabusa would be like trying to hit a piece of "dust" in space.
This would be like hitting a one-millimeter target in Brazil from Japan. One of the scientists observed, "If Hayabusa achieves these goals, it wiil have done what no spacecraft has ever done."
Getting to Itokawa was difficult, but touching down and collecting the soli samples was next to impossible.
