There's an issue with one of the lunar Lander's solar cells.

月球着陆器的其中一个太阳能电池存在问题。

This robot walks around under user control. In the middle are some solar cells and some wiring attached to it.

这个机器人是人工控制的，中间是太阳能电池和一些连接在其上的布线。

Maybe that's a solar cell, for example.

例如，也许那是一块太阳能电池。

In the middle are some solar cells and some wiring attached to it.

中间是一些太阳能电池和一些连接到它的电线。

It may just have -- may just have to wait until the sun actually moves position and can reach those solar cells.

只能等待太阳移动的位置能够实际照射到这些太阳能电池的时候到来。

At this scale, batteries are just too heavy to be carried onboard, so the researchers used ultra-lightweight solar cells.

在这种规模下， 电池太重而无法随身携带，因此研究人员使用了超轻型太阳能电池。
