1 .Setting up a permanent station on Venus may not be without challenges, but it is certainly possible.

2 .One solution that's been proposed is to establish a station that would be floating in Venus's atmosphere, like a balloon, rather than standing on its surface.

3 .The station would float about 50 kilometers above Venus's surface. On a station located high in the atmosphere, the problems the reading mentions can be solved.

1 .First, atmospheric pressure.
该句暂无译文！
2 .Well, it is a well-known physical fact that high up in the atmosphere, the pressure is much lower than at the surface.

3 .So while the pressure at Venus's surface is too high for humans, 50 kilometers up in the atmosphere, the pressure's equal to the normal pressure we’re used to here on Earth.

4 .There would be no danger of the station getting crushed.

1 .Second, water and oxygen.
该句暂无译文！
2 .Well, as you read, Venus's atmosphere contains compounds such as carbon dioxide and sulfuric acid.

3 .There are chemical processes that could be used on the station to make water and oxygen out of these compounds.
该句暂无译文！
4 .So the water and oxygen necessary for human survival could be produced using chemical materials that can be easily obtained from Venus's atmosphere.

1 .Third, the light blocking clouds.
该句暂无译文！
2 .Well, it is true that there are still clouds 50 kilometers above Venus's surface.
该句暂无译文！
3 .However, clouds above that level are not very thick, so there would be a considerable amount of sunlight filtering through.
该句暂无译文！
4 .Moreover, at you read, the clouds reflect sunlight.
该句暂无译文！
5 .The station can make use of this reflected light too.
该句暂无译文！
6 .In other words, its solar-powered cells could collect both the direct sunlight filtering from above and the sunlight reflected by the clouds below.

7 .More than enough electricity could be generated this way to power the station.
