Some of the most historic and interesting sound bites from NASA space missions are now available for download as ringtones on your phone, or on your computer for alarms and notifications.
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. A new NASA Web page has more than 35 different sounds, including “Houston, we've had a problem," and segments from President Kennedy’s historic Moon speech.
The NASA sounds are available in both MP3 and M4R (iPhone) files. NASA will update the collection as new sounds become available. To listen to and download the sounds, click here.
