And as you might expect, visiting the bathroom in a microgravity environment throws up an assortment of grim challenges.

正如你所料，在微重力环境中上厕所会遇到各种严峻的挑战。

The arrays will provide electricity, the sustained systems and equipment while augmenting other power to continue experiments in the station's unique microgravity environment.

该阵列将提供电力、持续系统和设备同时增强其他力量，继续在空间站独特的微重力环境中进行实验。

But over time, and in the microgravity environment of outer space, this tiny force was enough to knock the probes off-course.

但随着时间的推移， 在外层空间的微重力环境中，这种微小的力足以将探测器撞离轨道。

Astronauts often experience things like trouble sleeping, puffy faces, and loss of muscle mass, but perhaps the most serious damage a microgravity environment causes is to the bones.

宇航员经常会遇到睡眠困难、脸部浮肿和肌肉质量下降等问题，但微重力环境造成的最严重损害可能是骨骼。

But in a microgravity environment like Mars, human bone and muscle cells won't get these cues, resulting in osteoporosis and muscle atrophy.

但在火星这样的微重力环境中，人体骨骼和肌肉细胞无法获得这些信号，从而导致骨质疏松和肌肉萎缩。

So scientists have been experimenting with " mighty mice" to see if a drug could be produced one day that could help astronauts keep their muscle in a microgravity environment.

所以科学家一直用“太空飞鼠”做实验来探究是否某天能有一种药可以帮助宇航员使他们的肌肉保持在微重力环境下。

One of the experiments on board right now is MRSA, a dangerous bacteria that scientists are hoping to study in the ISS's microgravity environment.

目前船上的一项实验是 MRSA，这是一种危险的细菌， 科学家们希望在国际空间站的微重力环境中对其进行研究。

To better understand these changes, Kelly took part in a bunch of studies that tracked how his eyes, his bones, his heart and even his brain changed due to the microgravity environment.

为了更好地理解这些变化, 凯利参加了一系列的研究, 观察他的眼睛, 骨头, 心脏, 甚至大脑在微重力环境下的变化。
