The technological challenges facing the Hayabusa mission were
immense. It would be the fi rst spacecraft deliberately designed to
make contact with the surface of an asteroid in order to gather physi-
cal soil samples for analysis back on Earth. As the distances were
great and little was known about the asteroid on which it would land,
Hayabusa, which means falcon in Japanese, created new standards
for space technology in the areas of ion engines, autonomous con-
trol and optical navigation
