You can now hear Buzz Aldrin and Neil Armstrong on their journey to the moon



Ninety-nine years ago, astronauts Neil Armstrong and Buzz Aldrin made history when they landed on the lunar surface.

Now, NASA, in collaboration with the University of Texas at Dallas (UT), has published 19,000 hours The live broadcast of the landing, which saw millions of people around the world on July 20, 1969, was replaced by legendary entertainment, shortly after The Eagle lunar module touched down with just 30 seconds of fuel.

Armstrong radioed the mission control with these words: "Houston, Tranquility Base here, the Eagle has landed." Back in Houston, NASA staff broke out in celebration, and capsule communicator Charlie Duke jokingly responded, "You have a group of guys who turn blue, we breathe again."

But over the course of the eight days A three-hour mission, countless other conversations took place between Armstrong, Aldrin and the third astronaut Michael Collins and the operators on the ground. Every second of this round-the-clock communication known as "loops" was recorded on tape.

These fragile images are stored in special air-conditioned vaults with the only working tape recorder to be stored in NASA's Johnson Space Center

Now UT researchers and space agency investigators are transforming them thanks to a dedicated collaboration Completed records of analogue to digital format and this now for the first time provided online transcripts of the talks. Together, the footage results in a fascinating, untold story of Apollo 1

1.

"The effort is a way to contribute to the recognition of countless scientists, engineers and specialists who worked behind the scenes of the Apollo program to make this a success, "said John HL Hansen, Project Project Leader. "These are really the heroes behind the heroes of Apollo 11!"

Much of the audio material consists of critical, but rather dry technical correspondence between the crew and the ground support staff, occasionally interrupted by insightful discussions about personal life. But the recordings also contain some captivating moments.

One of the most frightening is the conversation that took place during the "Life and Death" drama just before the touchdown, when the lunar module's computer systems threatened to break off the landing. There are also a number of humorous exchanges that reveal the ability of astronauts to remain calm even in stressful situations.

In one of the tapes, two NASA air traffic controllers work with Aldrin to find out why the sensor was designed to measure its breathing, did not work properly. After 10-15 minutes you still can not tell what the problem is. Buzz jokes: "Well, if I stop, I'll let you know!"

Another recording that Aldrin jokingly laments is the fact that so much of the Earth's surface is water and that missionary control requires them to do something about it.

"We are approaching the 50th anniversary of Apollo, and I am really glad that this resource becomes available," Mark Geyer, director of the Johnson Space Center, said in the statement.

"Experience is one of the best teachers, and as we continue our work to expand human exploration of our solar system, back to the Moon and on to Mars, we stand on the shoulders of the giants who passed Apollo a unique insight into what it takes to make history and what it takes to shape the future.
