Balancing Brains

Koyaanisqatsi writes "NASA researchers are learning more about the human brain by studying how astronauts regain their balance upon returning from space. Back home, an astronaut's brain no longer knows how to interpret what the senses tell it. The brain has to adapt to a zero gravity environment in space, then readjust back on Earth. The transition may bring on motion sickness. Ever wonder how your brain would react? (Full Story). Same article is also available via streaming audio or as a downloadable mp3 file."

    The moon is one thing, but even Mars is a 3-year-flight away.

    Mars is only a 3 year flight if you go for a least-fuel cost route. Constant acceleration during the correct flight window brings that down to 2 weeks. And pretty much anything in between is possible.

    Not to nitpick, but this is a common misconception that is a building block for many arguments against Mars missions.

    A fair and reasonable rejoinder. I apologize if my statement came off as an absolute; it was not intended in that fashion. That said, the economics of space flight currently requires that we only carry enough fuel to get the job done. There's still very little margin for "wasteful" burns.

    Again, a fair comment. :) As technology brings us ever more efficient fuels and engine designs, we may within our lifetime find an adequate solution to that enables us to approach such a mission based on least-time rather than least-cost. I don't expect that to happen within, say, the next ten years, however.

    Somehow reading the article reminds me of the Neo's training period in the Matrix movie. If they actually can make the brains..

    "We know that astronauts are just on the verge of readapting to Earth in the 2 to 4 day time frame after short duration space flight. So we thought, why don't we go to day 3, when we think somebody is just about adapted, and see if we can cause the brain to switch states."

    shift states, would not the next thing to try to be able to create those states. Like fast-forwarding (as in FF>>) or uploading a scenario into the brains and balance control...
