Wie eine Reise zum Mars die Augen eines Astronauten schädigen kann | Nach Angaben der NASA leiden etwa 70 % der Astronauten an Bord der ISS unter Schwellungen im hinteren Augenbereich. Die Symptome verschlimmern sich und werden dauerhaft, je länger sich ein Astronaut im Weltraum aufhält, was bei längeren Missionen – wie künftigen Reisen zum Mars – eine Herausforderung darstellt

Let’s first get to the moon and start collecting data about how human bodies react to complete different environnements. The astronauts on the ISS still have the protection from the Earth’s magnetic field…
I’ve said it many times in the internet. Out bodies are not rubber, they will NEVER adjust to different gravity. The only population that Mars can EVER sustain is robotic. The only humans that can live there are NOT humans, they would be a different breed of humans, changed by future gene tech that’s will arrive in the next century.
This is the best case.
We should aim for O’Neil cylinders with 0.9-1 of Earth gravity and mine and process exotic materials at Earth orbit. Everything else is BS of people who skipped school biology. And there is no self-sustainability outside Earth anyway without processing asteroid materials.
Going to Mars is stupid. It is leaping 3 steps ahead: a new orbital station with orbital factories and supply docks and depos, a long range spacecraft technology to move a lot of mass, and gene modifications. That’s like inventing electricity and saying „yeah, hydrogen fusion is our goal“.
