Despite its hellish surface, Venus turns out to be quite an attractive planet for exploration. NASA scientists are developing a project of conquering its upper atmosphere – a fleet of solar-powered aircraft may build up a whole cloud city in the future.
The challenging conditions on Venus’ surface – that is, 92 Earth’s atmospheres of pressure, the sulphuric acid rain with lightning bolts and temperatures of nearly 500 C – made scientists literally turn to cloud castles. This idea has been recently developed in NASA’s High Altitude Venus Operational Concept (HAVOC) mission that is set to send a series of missions to the planet.
“The vast majority of people, when they hear the idea of going to Venus and exploring, think of the surface, where it’s hot enough to melt lead and the pressure is the same as if you were almost a mile underneath the ocean,” aerospace engineer at NASA Langley Research Center Chris Jones told IEEE Spectrum magazine. “I think that not many people have gone and looked at the relatively much more hospitable atmosphere and how you might tackle operating there for a while.”.. see more
