NASA unveiled 19,000 hours of communication voice of 'Apollo 11' which made the first landing of the moon the first time

by Marc Van Norden

NASA and the University of Texas carried out a project to digitize the enormous communication data exchanged at the mission of Apollo 11 which made the first moon landing of the human race successful. The project digitizes the audio data of 19,000 hours, and this digitized data is published on the Internet archive . It is valuable data including not only the sound of the historical moment where mankind landed on the moon for the first time but also a bit of conversation with the astronaut and mission control.

NASA's astronauts are subjected to rigorous training to deal with every accident occurring during the mission, but not only astronauts will deal with this problem. Various experts such as engineers and doctors gather in mission control that supports the activities of astronauts on the ground and we will do as much support as possible from the ground when problems arise. Even at Apollo 11 which accomplished historical feat, astronaut and mission control showed a great teamwork, but its contents were released on the Internet archive so that anyone can listen to it at any time.

As a captain of Apollo 11, a conversation by Mr. Buzz Aldrin, who was the first lunar landing on the Apollo 11 as well as the astronaut Neil Armstrong who is also known for the first time as a person walking on the moon And communication contents of Apollo 11 and mission control at the time of occurrence of "1202" error that we had never experienced in training, so that valuable communication voice can be heard.

John Hansen, chief researcher at the University of Texas who has promoted the project, said, "One thing that each person working for NASA is proud of doing is that they always cooperate I was working on my work, "he says frankly what he felt through digitalization of communication voice.

According to Mr. Hansen, digitalization of communication voice was not an easy task. Although the communication voice was recorded on 170 tapes, although each tape had 30 independent audio channels, the player who plays the tape can read only one track at a time It seems that it was necessary to play each tape 30 times at a time because it was not there. Therefore, Mr. Hansen et al ordered custom tape player which can reproduce 30 tracks at the same time, which makes it possible to drastically shorten digitizing work. Although it is digitization work of communication voice originally thought to take several years, it finally ended safely in about 4 months.
