In 2010 Hayabusa, a Japanese spacecraft, visited an asteroid called Itokawa but returned with less than a milligram of it.

2010 年，日本航天器隼鸟号访问了一颗名为糸川的小行星，但返回时带回的物质不足一毫克。

This became more clear when the Japanese Hayabusa spacecraft visited the asteroid Itokawa, and saw what can only be described as a jumbled mess.

当日本的“隼鸟号”宇宙飞船访问伊川小行星时，这一点变得更加明显，并且还观测到了只能用混乱来形容的景象。
