NASA Wants You! (To Sit in a Spinning Room) 35

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.

      Something is afoot...there's nothing in the current (read non black programs) capable of sustained 2G acceleration.
      Either they're doing REALLY advanced research or there's potential for round trips to Mars in a week or so....in the near term!

  • 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.

      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?
      .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.
        • OK. When you make a centrifuge you have to put a counterweight on the opposite side, so you don't rip the bearing apart, so when they say 58 ft they mean diameter. Hence r = 29 ft = 8.8 m. Put this together with 15 rpm and you get 22 m/s^2 or about 2 g.

          Glad I could help.

          Of course you have to add this in quadrature with the Earth's grav, so you get more like 2.4 g.

        • 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.

      • 1) Changing a = v^2/r to a = w^2r is trivial, considering that v = wr. You neglected that w must be in radians per second. And, if this centrifuge works like I think it does, 58 feet is the diameter Therefore...

        w = 2(pi)*.25
        a = .25(pi)^2*29 = 71.555 ft/s^2 or 21.810 m/s^2 or 2.225g

        (Yeah I used w for omega. They look similar.)
        • You can use ω to get the character, and π to get the character.

          ² works to get the superscript, as in . Here's to clarity and accuracy.

          • Actually, the only one that works in Netscape 4.x is ², which I had forgotten about. ω and π don't do anything. Yes, I know, Netscape sucks and all, but it's what I've got to work with at the moment.

    Sure.
  • 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.

    • I thought they did that on Dragon Ball Z characters. I seem to recall a few episodes in which they trained in a hyper-gravity chamber.

      Seriously, though, once the experiment terminates, it's got to be scary to feel your normal usual weight again. I would imagine that you would make all sorts of mistakes, such as trying to lift a spoon and flinging it halfway across the room (woops!). Given the length of the experiment, though, you would probably not have the opportunity to get used to the extra G too much.
