This is only a small part of a large collection of space sounds. I like these the best because they're from the oldest satellites (although some have been recorded relatively recently!) You can find links to sounds from 1961-present, and more information on how these were obtained on this page of the same website: http://www.dd1us.de/historical%20sounds%20from%20space.html
Hi, if you'd like more recent recordings you can check over https://network.satnogs.org an open-source satellite ground-station network with several ground-stations participating that records data from scientific, meteorological, even astronauts on-board the ISS on amateur radio contacts.
