NASA: NASA, University of Texas at Dallas Reveal Apollo 11 Behind-the-Scenes Audio. “NASA’s Johnson Space Center has the only functional remaining tape recorder capable of playing those approximately 170 remaining tapes. But the time and effort of converting them to current digital formats was daunting, and required the tape deck to be modified from being able to handle two-channels at a time to handle the 30 channels on the historic tapes. But through a collaborative effort with The University of Texas at Dallas (UT Dallas), the conversion finally has been completed, and the unique perspective of those at the core of supporting humankind’s ‘giant leap’ is available to download and listen to all 19,000 hours of audio recordings.” This is an incredible achievement. I posted in December about what it took behind the scenes to get this digitizing done.
