Free space sounds from NASA


Quiet simply, Thank you, NASA! 

A blog post from creative digital music, NASA Posts a Huge Library of Space Sounds, And You’re Free To Use Them points to a bunch of useful resources. There’s NASA stream on SoundCloud with a bunch of audio clips under the CC Non-Commercial licence. And a range of things on, which can be found with a search, or browse through the massive NASA Audio Collection (Public Domain licence).
