Just in time for SoundCloud's newly-announced integration with Twitter, the US space agency opened its own account on the audio-clip sharing service and has already filled it with 60 or so recordings, including "the Eagle has landed" and plenty of choice quotes from President Kennedy.

"You can hear the roar of a space shuttle launch or Neil Armstrong's 'One small step for (a) man, one giant leap for mankind' every time you get a phone call if you make our sounds your ringtone", NASA says on the account, "or, you can hear the memorable words 'Houston, we've had a problem', every time you make an error on your computer".

But there are weirder, more otherworldly noises too, like bleeps and bloops from Sputnik, radio waves being interpreted by spacecraft instruments, supposed "interstellar plasma sounds" and part of a pop song written by NASA scientist/musician John Marmie about finding water on the moon.

While the various recordings are perhaps unlikely to wind up on too many phones or PCs belonging to those nostalgic for the moon landing era (has anybody at NASA tried setting a custom ringtone on an iPhone?), the shareability of the SoundCloud format is surely aimed at driving some much-needed interest in the space agency among the younger crowd.

All the sounds are public domain too, so they're sure to find their way into throwback movie projects, advertisements and the intros to grindcore metal songs. You can browse the full library here, and check out a few highlights below.
