Behind the Scenes of Apollo 11: NASA releases 19,000 hours of secret audio feeds for the mission



Forty-nine years after NASA wrote history by landing two humans on the surface of the Moon and safely returning them to Earth, the Space Agency has published all of the 19,000 hours of audio recorded during the Apollo 11 mission.

Although m of the world focused on the first Earth-Moon conversation at 4:18 pm EDT July 20, 1969, when Neil Armstrong and Buzz Aldrin landed the lunar module Eagle with only 30 seconds remaining fuel, the EDT became entire mission recorded

After the original tapes were painstakingly digitized, the audio was put online.

Hundreds of audio conversations between air traffic controllers and other teams supporting the mission went through a complicated intercom system every minute of the mission.

"The untold story of this major 8-day, 3-hour mission from Armstrong, Aldrin and Michael Collins was 24

The space explorers' trio took off from the Kennedy Space Center in Florida at 9:32 am on July 16, 1969, landed on the moon on July 20, and resumed at 1:54 pm on July 21, and splashed at 12:50 on. July 24 in the Pacific Ocean.

Ground-based Multi Purpose Support Rooms (MPSRs) coordinated every technical, planning and management detail and mission control mission and Apollo 11 flight directors Clifford Charlesworth, Gerry Griffin, Gene Kranz and Glynn Lunney.

The talks took place via so-called communication loops.

The air-to-ground loops between the Apollo 11 crew and the Mission Control were exposed to the media and the public as they passed, as NASA assumed its responsibility to share its work with the American public.

"backroom loops" in which individual experts have to date discussed details in their systems and at times details of their lives, included in special air-conditioned vaults

HOW THE APOLLO WERE CONVERTED 11 AUDIO BANDS [19659016] John Hansen Wires and Installs Newly Designed and Designed Playhead 30-Track Readhead ” class=”blkBorder img-share” />

NASA's Johnson Space Center has the only working remnant tape recorder capable of reproducing these approximately 170 remaining tapes.

However, the time and effort required to convert them to current digital formats was daunting, requiring the tape deck to be modified to handle two channels at a time to handle the 30 channels on top of it to handle historical tapes.

But through a collaboration with the University of Texas at Dallas (UT Dallas), the conversion has finally been completed, and the unique perspective of those who support the "giant leap" of humanity is ready to download and listen to every 19,000 hours of audio recording

None of the original 30-track audio tapes had been fully digitized before.

The first major technical challenge was to revise the more than 45-year-old SoundScriber two-track audio playback system to support 30-track playback.

The team had to design, install and test the new 30-track head at NASA, which could simultaneously play all 30-track audio tape channels and build a 30-channel digitization system pipeline.

Since many of the tapes documented the silence between the conversations, the team needed to develop a system to detect when conversations begin and end, and an active learning system to create accurate transcripts of conversations.

The team also developed a "hotspot detection system" to set the mood The speaker's laughter to gain insights into the behavior and cohesion of the astronauts and support team in Mission Control, and a web-based, interactive interaction module for the Apollo mission to help younger users gain the highly technical content of many conversations [19659003] In addition to the 19,000 hours of digitized audio, the team produced transcripts of each conversation and linked them to the digital audio database.

This allowed for the development of metadata that helps researchers crawl through the hours and hours of audio to find the conversations most relevant to their area of ​​interest.

"We are approaching the 50th anniversary of Apollo and I am very pleased that this resource will become available," said JSC Director Mark Geyer.

& # 39; experience is one of the best teachers, and as we continue our work of expanding 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.

"These tapes provide a unique insight into what it takes to make history and what it takes to shape the future."

"The effort," said John HL Hansen, director of research for the effort, "is a way to 'recognize the myriad of scientists, engineers and specialists who have worked behind the scenes of the Apollo program To make this a success, these are really the "heroes behind the heroes" of Apollo-11!

In addition to the life-and-death drama as a lunar module danger threatens Eagles computer system to cancel the landing, the talks also give insight into the "people in the loop" Apollo possible, including many humorous moments.

Hansen noticed a spot on the tapes where two NASA air traffic controllers are working with Buzz Aldrin because for some reason the sensor measuring his breathing is not working properly.

In the Audiospot – they explore a number of reasons, ask questions and maybe 10-15 minutes.

  On July 24, 1969, the Apollo 11 crew splashed with commander Neil Armstrong, command module pilot Michael Collins, and lunar module pilot Buzz Aldrin after the first moon landing in the Pacific Ocean.

After spraying, the crew of the Apollo 11 underwent a 21-day quarantine. The purpose was to protect against the low possibility of moon infection. This procedure was discontinued after Apollo 14. This photo offers an open view of the astronauts in the Mobile Quarantine Facility.

Finally, in his own sense of humor, Buzz tells NASA staff, "Well, if I stop breathing, I'll let you know!"

In one example, Aldrin laments the fact that so much of the Earth's surface There is water and asks if mission control can do something about it.

In another, the air traffic controller He is responsible for the video on the large screens on the front wall of Mission Control and provides a channel on which air traffic controllers can display black and white videos on their consoles. Flight Director Gene Kranz says these consoles should be used to view data:

While the Apollo 11's 19,000-hour worth of tape data represents a significant achievement that greatly enhances access to this mission, it represents only 25 percent of audio recordings for the entire project Apollo.

The remainder – which are still being digitized and transcribed – cover the early Apollo test flights in orbit around Earth, and the two test missions that sent Apollo 8 around the Moon in December 1968 placed Apollo 10 in orbit around the Earth Moon in May 1969, the five later Apollo missions that landed on the Moon, and the "successful failure", in which Apollo 13 was crippled by an oxygen tank blast and mission control had to use all the innovations to bring the crew of three home safely to earth.

THE APOLLO MISSIONS

  On July 16, 1969, American astronauts Neil Armstrong, Edwin "Buzz" Aldrin, and Michael Collins launched into the giant Saturn V rocket at the Kennedy Space Center, Florida on their way to the United States Moon during the Apollo 11 mission.

  On July 16, 1969, American Astronauts Neil Armstrong, Edwin "Buzz" Aldrin, and Michael Collins of the Kennedy Space Center in Florida picked up the giant Saturn V rocket heading toward the moon during the Apollo 11 mission.

On July 16, 1969, American astronauts Neil Armstrong, Edwin & # 39; Buzz & # 39; Aldrin and Michael Collins with the giant Saturn V rocket from the Kennedy Space Center in Florida on their way to the moon during the Apollo 11 mission.

The Apollo program was designed to land people on the Moon and safely take them to the Moon Earth and six of the missions (Apollo 11, 12, 14, 15, 16) and 17) achieved this goal.

The NASA program led American astronauts to make a total of eleven spaceflights and walk the moon.

The first four flights tested the equipment used in the Apollo program.

Six of the other seven flights landed on the moon.

The first Apollo flight took place in 1968.

The first moon landing took place in 1969.

The last moon landing took place in 1972.

A total of 12 astronauts went on the moon.

The astronauts conducted scientific research there, studying the lunar surface and collecting lunar rocks to bring it back to Earth.

The six missions that landed on the Moon provided a wealth of scientific data and nearly 400 kilograms of lunar samples.

Experiments included soil mechanics, meteoroids, seismic radiation, heat flux, lunar field measurements, magnetic fields and solar wind experiments.

The first manned mission to the moon was Apollo 8.

It circled the moon in 1968 on Christmas Eve.

However, Apollo 8 did not land on the moon. It circled the moon and then came back to earth. The crew consisted of Frank Borman, Bill Anders and Jim Lovell.

The first moon landing took place on July 20, 1969 on the Apollo 11 mission.

The crew of Apollo 11 was Neil Armstrong, Michael Collins and Buzz Aldrin. Armstong and Aldrin walked on the lunar surface while Collins remained in orbit around the moon. When Neil Armstrong became the first person to walk on the moon, he said, "This is a small step for a man, a great leap for humanity."
