Can anyone link me to some resources on the background noises heard inside gemini and apollo capsules? Even the LEM is of interest. I'd like to know what the thruster firings sounded like, and if there were any hissing, humming, banging, thermal pops and pings, things like that. Engine firing too, of course, but mostly the ambient sound and the RCS. Was it possible for the astronauts to monitor or diagnose ship activity by ear? Sounds of valves and relays opening and closing, etc
Here are some of my experiences as a totally blind person. I rely heavily on audio ambiance. Here are some YouTube videos of a Columbia launch inside the orbiter, and a Soyuz ride into Space.and
i've also come across some videos of the Endeavour mission posted in 2012, it seems the crew recorded several videos of their docking and disembarkment to the ISS, along with time on board. There is some occasional radio chatter and silence here and there but its mostly the ambient sounds and crew talking to each other, or themselves. These next seven videos I'll try to put in order. Video 1:
Video 7:There are a few video's available of space walks as well taken with go pro's, although for obvious reasons they aren't inside the suits themselves. This one has some rather interesting audio though, the sounds of the camera being moved around, and the hum of nearby equipment attached to the ISS, etc.
This is an interesting topic, this isn't quite what you want but its a start. There was an audio tape made from accelerometer recordings on-board the Olympus communications satellite, launched 1989. Of course this doesn't show what it would sound like to be present there in a pressurised cabin.
My memory is that one could hear the wheels running:
- sounded like the wall of sound one hears in the depths of a ship
and thrusters firing in pulsed mode to off-load momentum built up by the wheels:
- sounded like a machine gun
I had a quick search just now to see if it had found its way onto the internet but without luck. It seems it can't be beyond the wit of someone to rig something similar up with a modern satellite so perhaps something else will surface.
