I realize it's not ham specific, but if you want to hear the archived ISS / Mission Control audio, it's being archived at http://issaudio.project10.net

Files are recorded using VOX, and are timestamped in Eastern Time (ET).

Never look at the newest file, that's just a placeholder for the current hour. Live audio is still available at NASA, but if you miss something or want to go back and look for specific events, use the NASA timelines and convert to ET (-5 right now) and you can pull it up!

PS During shuttle missions, the feed switches over to NASA TV audio so you'll get archives of everything
