...but there are still sounds that come from the sky in the form of radio emissions. I came across a very interesting web page by a Swedish space enthusiast named Sven Grahn. He has an interesting hobby of using radios to track and record the sounds from spacecraft. He has quite an extensive collection of sound recordings on his site all the way back to Explorer-1 (though he didn't record the older stuff). There is a lot of links and articles on the web page too. I think I could spend a long time reading and listening to his stuff.
Reminded me of the "Lost Cosmonauts" site that claims to have recordings of Russian space disasters and the final gasps of Cosmonauts before they died in a horrible fiery death. I'm not really sure what to make of this site, but I'm still wondering if Yuri Gagarin may have only been the first to survive a trip into space? There might be some mystery in there still.
