这枚太空舱，如不出所料，将会装有系川小行星上的矿，这颗半公里长的小行星的轨道经过地球。

This capsule, it is hoped, will contain material from Itokawa, a half-kilometre-long asteroid whose orbit crosses the Earth's.

科学家希望探测器对“系川”小行星的探访会给他们带回有关小行星构造的信息，并进一步得以了解太阳系。

Scientists hope the probe's visit to Itokawa will give them information about the formation of asteroids and thus the solar system.

隼鸟号2003发射升空，于2005年进入系川小行星的轨道，意图是靠近并发射一个抛射体进入其表面，捕获撞击产生的尘埃。

Hayabusa was launched in 2003 and matched orbits with Itokawa in 2005. The intention was to get close, fire a projectile into the surface and grab some of the ensuing dust.
