One day these manned space missions may reach out even further to distant planets with alien atmospheres, atmospheres that may support their own life forms.
Else where in our universe on distant planets, alien air may support extraterrestrial life. Joel Hagen has spent 20 years imagining how those atmospheres could have affected 1 their inhabitants.
That's where some of the real creative joy comes from, trying to think about everything that has happened here and then take yourself one notch 2 beyond and imagine what haven't i seen here, and then try to visualize 3 that.
One of the possibilities that intrigues 4 Hagen is life on a gas giant planet.
This is an environment so completely alien to what we are used to, even a planet like Jupitor for instance has no solid surface, just a gradual transition of density 5 of gas, and i think we might imagine creatures in an atmosphere like that that sort of rely on buoyancy, perhaps being able to generate hydrogen for example somehow within their body.
These creatures would be like hydrogen filled blimps, lighter 6 than the air, able to float amongst the gas clouds.
The concept that i have here is to have perhaps colonies of microbes in the sort of tentacle 7 like structures here, and these microbes generate the hydrogen which in turn sort of inflates 8 the gas bag here, creature like this then can sort of float freely...
