NASA Wants You! (To Sit in a Spinning Room)

slinted writes: "Bottomquark recently posted that Nasa scientists are looking for a few good men (5"8' or less) to participate in hypergravity experiments. The experiments entail 7 'habitation sessions,' 5 of which will last up to 22 hours of spinning at up to 2G in a chamber 7.6 feet long and 6 feet wide. Since the experiments are at Ames Research Center, in Mountain View CA, this might be perfect for some techies 'in between projects.'"

    "At any time, and for any reason, participants will be able to terminate the session by pressing a button, or simply by asking the medical monitor to stop the session," Cohen noted. A laptop computer with electronic games, questionnaires and behavioral tests loaded onto its hard drive also will be on board. "Your use of this computer will be completely at your discretion," Cohen tells candidates.

  6. More like 4.5 G, right? by Muad'Dave · · Score: 2

    If I remember my high school physics, centripedal acceleration was a = v^2/r. If we assume the 58 feet mentioned in the article is the radius of the thing, we get 364.4 ft for the diameter. They mention 15 rev/min, which is 0.25 rev/s, making the velocity of the people compartment 91.1 ft/s. Doing the math, (91.1^2/58) gives you 4.47 G, right?

      No, the diameter would be 116 feet. The circumference would be 364.4 feet.

      But if you really remembered your physics you'd know that a = r. From r and a you can calculate directly, or vice versa.

      .25 * 58 feet * .3048 meter/ft = 1.10 m/sec&sup2. I'd assume that there's an error in the article or in your analysis (I'm being booted off and don't have time to check now).

      Let's see.. 58 ft is about 17.7 meters. With a revolution every 4 seconds, &omega = 1.6 1/sec. So the acceleration is about 43.6 m/sec&sup2, or 4.45 times g. That theses numbers agree stands to reason: both formulae are the same, if you remember that &omega = v/r.

      You are, of course, correct. I was too hurried to see that I had forgotten to multiply by 4. (Damn, does pi ever suck in the typeface on this lousy computer!)

      By the way, you can get the omega character with the sequence ω, and the superscript 2 with ². This doesn't require much extra typing and really adds to your clarity.

    You might want to actually read the article.

    They are talking about getting data for a centrifuge on a spacecraft. Possibly to aid astronauts in acclimatizing to a destination planet on a long long trip, Mars for example. There is no mention of any spacedrive stuff....

  10. I thought they did that on rats by phr1 · · Score: 2
    They spun rats at 3g for quite a long time (weeks or months, maybe even from birth--I don't remember). The rats came out as super-rats, with much stronger muscles than normal rats. Meanwhile, astronauts who spent long periods weightless lost muscle mass. It was sort of embarassing for space buffs who thought zero g would be good for you--it's sort of the opposite.

    So this experiment sounds cool. I'd look into signing up except I'm over the height limit.
