One year is just too short. Imagine the changes there would be after multiple years. And even more interesingly, after multiple generations. We really need to send more people out there and expand all sorts of space research.We are still human, even in space.
Will SpaceX astronauts be known as X-men?I think you mean we are human until we go to space, then we are mutants.
So not only is he Tony Stark, he's Xavier too?Will SpaceX astronauts be known as X-men?
^ This. I think serious bio-engineering is maybe two or three decades away. By the time we're out inhabiting the solar system, we'll be genetically suited to new environments. Not to mention the prospect of becoming artificial/cybernetic, which is also around the corner.I think you mean we are human until we go to space, then we are mutants.
There is little that you can use to conclude that. We have no idea how far reaching our biological limitations are for space travel.I too am curious about the thread title, I was expecing a discussion on the impossibility of FTL travel and so forth. But overcoming biological limits is the least of our worries.
Yeah, it's gene expression. We can see these changes in stressful terrestrial life as well. However, the astronaut's body's reaction hints at how stressful space travel is to humans.They actually made a fix article https://www.livescience.com/62044-scott-kelly-space-genes-not-changed.html.
The change was in gene expression, I don't find it to be significant considering the extreme difference in their environment
