Re: [meteorite-list] Re: audio transmissions

[stan .]

the atmosphereic pressure on mars is like 7 or 8 millibars - less than 1% of 
that of atmospheric pressure on earth. in theory sounds could be recorded, 
but they would be extreemly faint, and it would be likely impossible to hear 
any sounds generated even moderate distances away. i guess thas why audio 
transmissions were never considered a priority for mars. the hyugens probe 
will travel through a dense atmosphere, so sound transmissions will be more 
relevant as the probe should be able to hear noises made by things other 
than it's self..

Doug,
I have to laugh. I too built a parabolic reflector out of an old circular 
snow disc, sled, as a kid. I think I paid 75 cents for the plans. Kind of 
like X-Ray specs. I still don't understand why clear audio transmissions of 
environmental activity can't be achieved on Mars rovers for instance. It 
seems that radio technology would be simple to incorporate into the 
otherwise complex deal. Is my question really so naive?

Regards,
Bill

Hola, Stan would seem completely right to me.  I just have one question, 
though.  I remember being fascinated with the idea of building a 
supersensitive microphone as a kid, the kind that could hear a bird at 1000 
feet and a whisper in the next room, etc.  I actually did, though my 
inexperienced use of ferric chloride produced something that best picked up 
breathing that sounded like scuba diving sounds.

One claim -since I wasn't able to make a good parabolic antenna- and they 
were not really available at that time like now, that always had me dream 
about reaching out to the universe was the supposed ability of the 
microphone to pick up "sounds" from Jupiter.  Is there anything to this, 
and if there is, what Jovian "sound" is actually picked up from earth's 
surface?

Gracias
Doug
