In short
On December 6, 1877, Thomas Edison demonstrated the phonograph—a device that could record sound onto tinfoil-wrapped cylinders and play it back—at his laboratory in Menlo Park, New Jersey. It was the first practical machine ever built to capture and reproduce human speech and music, fundamentally changing how people could store, share, and experience sound.
How it unfolded.
The five-minute version
What actually happened.
Edison Demonstration of Smallsat Networks (EDSN) was a failed CubeSat constellation by NASA Ames, developed as a technology demonstration of satellite networking. The constellation would have consisted of 8 identical satellites. The satellites followed the CubeSat specifications for a 1.5U CubeSat.

Timeline
How it actually unfolded.
Edison Conceives the Phonograph
Edison sketches initial design concepts for a sound-recording device, inspired by telegraph technology and experiments with acoustic vibrations.
First Recorded Words
Edison records and plays back "Mary had a little lamb" on a tinfoil cylinder, confirming the basic principle works.
Public Demonstration at Menlo Park
Edison demonstrates the phonograph to visitors and Scientific American staff, playing back recorded speech and music from tinfoil cylinders.
Patent Application Filed
Edison files a patent application for the phonograph with the U.S. Patent Office.
Patent Granted
U.S. Patent No. 200,521 is granted to Thomas Edison for the phonograph.

Impact
What followed.
Edison's phonograph dissolved the boundary between live and recorded sound, setting the template for every music and voice technology that followed. The machine proved that information could be physically encoded and retrieved—a principle that would underpin everything from vinyl records to digital audio.
