Oh, and as for why I mentioned salt

I simply considered it fairly simple to grow mass amounts of it, and I think its sorta neat that they make optical elements out of it

Build astronomical observatories on the Moon? - et - 11/9/2006 9:04:35 PM
- For radio-telescopes, yes! (n/t) - Jacob Samorodin - 11/13/2006 12:41:49 AM
  - re: The viability of any telescope on the Moon depends heavily on if we can deal effectively with the electrostatic dust. But it would seem some antenna types wouldn't really be bothered much by dust. (n/t) - Chris Vancil - 11/16/2006 9:49:38 PM
    - Great place to use the Arecibo design. - alcaray - 11/17/2006 4:25:13 PM
      - re: Don't think so...a dish shaped bowl collects dust...even big holes may not stop the collection. (n/t) - Chris Vancil - 11/17/2006 10:51:27 PM
        
        Not one made of wire-mesh. (n/t) - Jacob Samorodin - 11/18/2006 5:59:43 PM
        
        re: I imagine it would epend on how fine the mesh is and it is electrostatic dust. (n/t) - Chris Vancil - 11/18/2006 11:08:29 PM
- I suspect we will not be motivated to do dedicated missions to the moon... - alcaray - 11/10/2006 6:20:22 PM
  - True. - Scott Evil - 11/16/2006 5:12:05 PM

  - No walking on the Moon Dust - nick hoffman - 11/11/2006 7:23:50 AM
    - Even if no one visited to stir up dust there would be a dust problem... - R.L. - 11/11/2006 8:51:02 AM

        I think you need to explore the financial model further - nick hoffman - 11/12/2006 2:40:48 AM
        
        It wouldn't be cheap is right.... - et - 11/12/2006 6:19:07 PM
        
        Hmmm.... I think I have to respectfully disagree... - R.L. - 11/12/2006 1:56:30 AM
        
        We don't disagree much on this. - et - 11/12/2006 6:39:20 PM

        While that was a fairly coherent burst of information.... - et - 11/14/2006 5:43:18 AM
        
        I understand that H20 is a greenhouse gas - gbaikie - 11/17/2006 2:43:30 AM
        
        Too bad there isn't a lot of mercury on the Moon. - TB - 11/13/2006 2:26:52 AM

        and yes, you can get lenses made from salt... (n/t) - R.L. - 11/12/2006 8:08:11 PM
        
        Why salt, why a lens, and why the attitude? - et - 11/13/2006 4:16:32 AM
        
        ? attitude? honestly, ET, I only have respect for you - R.L. (confused) - 11/13/2006 6:48:13 AM
        
        Oh, and as for why I mentioned salt - R.L. - 11/13/2006 7:10:41 AM
        
        And YES, the urge to lick the lens WOULD be unbearable.... - et - 11/13/2006 4:42:05 PM
