This week I be discussing the idea of habitation in
space and its effect on the human body, and how art has portrayed the concept
in the past. During the beginning of the Space Race between the US and Russia,
very little was known about the effects of space on the human body. Some
thought that the feeling of weightlessness would disorientate astronauts or
make regular bodily functions impossible. Although this idea was quickly
disproved, the absence of gravity still has detrimental effects through the
atrophy of muscles, and complications with human reproduction (Shere, J.). Most
of the early Gemini and Apollo missions were to verify that human beings would
be physically capable of living in space for the time required to get to the
moon and back (Kranz,G.).

More recently, the human population in space has become more
consistent with 6 astronauts currently living in the International Space
Station (Eshbach, B.). With past advances taken into account, one must ask what
is next when it comes to creating habitations in space or even other planets.
One concept that is scientifically favored is presented in Larry Niven’s Ringworld. Niven introduces the concept of a space station constructed like a donut or
halo. This ring would rotate causing a centripetal acceleration that would
mimic the force of gravity for the occupants. Replicating the force of gravity
will be instrumental in developing a permanently populated structure in space.

In addition to habitats in space, habitats on other
celestial bodies will be critical for the advancement of the human race.
Developing habitats on an alien surface will require large amounts of advanced
robotic and manufacturing technology. The following video features Rob Mueller
of NASA discussing his approach to creating habitable structures on the Martian
surface.

Expanding human habitability in space will lead to a massive
furthering of man’s innate pioneering spirit. Future generations will be able
to blast off into the truly final frontier.

I really enjoyed reading your post! I think it's so fascinating that the advancement of humans living in space is proceeding so quickly. Who knows what we will discover next if humans can find a way to live in space. I think that advancement is happening so fast that maybe one day there won't be anything new to discover in the future because we would have seen it all already.
ReplyDeleteI really liked your take on this unit. Moving out of our planet is a scary yet increasingly relevant thought. Although this could be a way to deal with overpopulation or the anthropogenic destruction of Earth, I think its important to note any health problems that may occur in an environment that humans haven't evolved to take on. I didn't know that astronauts used pressure chambers to increase blood flow and found that very interesting. There would likely be many unforeseen complications, but I don't think that will stop this next step in space exploration from happening.
