NASA has shared a collection of sounds from historic spaceflights and current missions.
The sound library includes engine sounds, launch sounds, countdowns, liftoffs, Neil Armstrong’s “One small step for (a) man, one giant leap for mankind” and more.
The NASA sound library is embedded below and you can download sounds via their SoundCloud account.
