What happens to the human body in deep space?

And there are still some total idiots (well, one in particular) who plan to waste unmeasurable amounts of resources sending people to Mars.

Watching what happened to Butch and Suni after just 6 months makes me question whether a trip to mars is possible. Maybe with some special forces types.

Once they construct a station that rotates on its axis to increase gravity to almost normal, they can do experiments at almost all gradients long term as the closer to the center the less gravity while at the outer edge gravity is near normal.

Time for engineers and scientists to get together and design such a station and let all nations be involved and all experiments and outcomes shared openly with all.

Man was not designed for zero g environment and as soon as something is removed from its perfect natural environment, it undergoes changes to try to adapt. Build something in space that maintains mans perfect natural environment and you will reduce issues to almost zero as a result.

The more involved the easier it can be, spread the load. The hardest part as always is consensus.

This is just another towards our evolution and progress as a species.

I remember seeing live on TV the second mission John Glenn took going to space. He was 80-something years old, and NASA wanted to see how space travel affects people during their whole lives, even when they get old.

And we keep on researching and learning. One day in the future mankind is going to evacuate Earth and there's a lot that we're going to need to know.
