我们对空间的环境已经有了一些了解,那就是高真空、微重力。在这种状态下是很有意思的,任何物体都处于失重状态,也就是漂浮在空中。如果我们到了那里进行太空行走,脚下没有路,可又到处都是路,随你怎样走,无所谓头朝上还是脚朝上,背朝上还是腹朝上。你要搬运几百千克甚至几吨的物体,也不费吹灰之力。 We have some understanding of the space environment, that is, high vacuum, microgravity. In this state is very interesting, any object is in weightlessness, that is, floating in the air. If we were there for space walking, there was no way under our feet, we could go all the way, and as you walked, it did not matter whether the head was up, the feet up, the back up, or the belly up. You have to handle hundreds of kilograms or even a few tons of objects, but also effortlessly.
