Watch 1969’s Apollo 11 Moon Landing “Live!”

Apollo 11 TV Coverage

54 years ago today, on July 20, 1969, Neil Armstrong & Buzz Aldrin landed on the Moon and went for a little walk. For the 15th year in a row, you can watch the original CBS News coverage of Walter Cronkite reporting on the Moon landing and the first Moon walk on a small B&W television, synced to the present-day time. Just open this page in your browser today, July 20th, and the coverage will start playing at the proper time. Here’s the schedule (all times EDT):

4:10:30 pm: Moon landing broadcast starts
4:17:40 pm: Lunar module lands on the Moon

4:20:15 pm - 10:51:26 pm: Break in coverage

10:51:27 pm: Moon walk broadcast starts
10:56:15 pm: First step on Moon
11:51:30 pm: Nixon speaks to the Eagle crew
12:00:30 am: Broadcast end (on July 21)

Set an alarm on your phone or calendar! Also, this works best on an actual computer but I think it functions ok on phones and tablets if necessary.

Back in 2018, I wrote a bit about what to look out for when you’re watching the landing:

The radio voices you hear are mostly Mission Control in Houston (specifically Apollo astronaut Charlie Duke, who acted as the spacecraft communicator for this mission) and Buzz Aldrin, whose job during the landing was to keep an eye on the LM’s altitude and speed โ€” you can hear him calling it out, “3 1/2 down, 220 feet, 13 forward.” Armstrong doesn’t say a whole lot…he’s busy flying and furiously searching for a suitable landing site. But it’s Armstrong that says after they land, “Houston, Tranquility Base here. The Eagle has landed.”. Note the change in call sign from “Eagle” to “Tranquility Base”. :)

Two things to listen for on the broadcast: the 1201/1202 program alarms I mentioned above and two quick callouts by Charlie Duke about the remaining fuel towards the end: “60 seconds” and “30 seconds”. Armstrong is taking all this information in through his earpiece โ€” the 1202s, the altitude and speed from Aldrin, and the remaining fuel โ€” and using it to figure out where to land.


Apollo 11’s Lunar Module Might Still Be Orbiting the Moon

After Neil Armstrong and Buzz Aldrin landed on the Moon 52 years ago today in the Lunar Module (aka Eagle), they rode the ascent stage of the LM back to rendezvous with Michael Collins in the Command Module (aka Columbia). After docking, Eagle was jettisoned and the three astronauts returned to Earth in Columbia. It was presumed that Eagle orbited the Moon until eventually crashing into the surface, but a recent analysis shows that the spacecraft may have entered a stable orbit and is still circling the Moon decades after the end of the mission, a priceless artifact of an historic achievement.

Most spacecraft in lunar orbit suffer from instability in their orbits due to the ‘lumpy’ nature of the lunar gravity which tends to cause the orbits to eventually get so elliptical that they hit the moon.

However, an amateur space fan wanted to narrow down the possible impact location and used orbit modelling software to propagate the orbit forwards in time until it hit the moon. He was surprised to find that it didn’t hit the moon, and remained in a stable orbit for decades, this suggests that the Eagle may still be orbiting the moon over 5 decades after being left there.

The paper detailing the analysis suggests that if Eagle has survived, it should be detectable by radar.

This is one of my favorite things I’ve ever done online…here’s what I wrote when I launched the project in 2009:

If you’ve never seen this coverage, I urge you to watch at least the landing segment (~10 min.) and the first 10-20 minutes of the Moon walk. I hope that with the old time TV display and poor YouTube quality, you get a small sense of how someone 40 years ago might have experienced it. I’ve watched the whole thing a couple of times while putting this together and I’m struck by two things: 1) how it’s almost more amazing that hundreds of millions of people watched the first Moon walk *live* on TV than it is that they got to the Moon in the first place, and 2) that pretty much the sole purpose of the Apollo 11 Moon walk was to photograph it and broadcast it live back to Earth.

In 2018, I wrote about what to watch for during the landing sequence.

The radio voices you hear are mostly Mission Control in Houston (specifically Apollo astronaut Charlie Duke, who acted as the spacecraft communicator for this mission) and Buzz Aldrin, whose job during the landing was to keep an eye on the LM’s altitude and speed - you can hear him calling it out, “3 1/2 down, 220 feet, 13 forward.” Armstrong doesn’t say a whole lot…he’s busy flying and furiously searching for a suitable landing site. But it’s Armstrong that says after they land, “Houston, Tranquility Base here. The Eagle has landed.”. Note the change in call sign from “Eagle” to “Tranquility Base”. :)


Teacher Tells Off Neil Armstrong for Faking the Moon Landing

In a letter recently published in a new book, A Reluctant Icon: Letters to Neil Armstrong, a teacher wrote a letter to the first human to set foot on the Moon accusing him of making the whole thing up.

Armstrong Letter Hoax

To which Armstrong replied:

Apollo 11’s Post-Lunar Quarantine

I do not know if hearing about other people’s quarantine experiences makes going through one yourself any easier, but the story of how NASA sequestered the returning Apollo 11 astronauts away from the rest of the world for 21 days is interesting for other reasons as well. The worry was that some sort of “moon bug” or “lunar plague” was going to make its way from the Moon to the Earth in the spacecraft or the astronauts’ bodies.

From the moment the Apollo 11 astronauts arrive back on earth from their epochal visit to the moon, they will be treated not as heroes but as bearers of the most virulent, devastating plague the world has ever known.

So NASA quarantined Armstrong, Aldrin, and Collins in a series of specially designed suits and environments until August 10, 1969. At one point, the three of them lived in a modified Airstream trailer in which the air pressure was lower on the inside than outside so if there was a leak, air would rush into the trailer, not out. Armstrong even celebrated a birthday in quarantine.

After Apollo 11, NASA did similar quarantines for 12 and 14 but abandoned them after that because they figured it was safe.

Oh, and if you were curious about the Soyuz launch yesterday that sent three astronauts to the ISS and how they were going to mitigate the chances of sending any SARS-CoV-2 up there, crews on all missions are subject to a mandatory 2 week quarantine before they leave (according to this press release).


A Deepfake Nixon Delivers Eulogy for the Apollo 11 Astronauts

When Neil Armstrong and Buzz Aldrin landed safely on the Moon in July 1969, President Richard Nixon called them from the White House during their moonwalk to say how proud he was of what they had accomplished. But in the event that Armstrong and Aldrin did not make it safely off the Moon’s surface, Nixon was prepared to give a very different sort of speech. The remarks were written by William Safire and recorded in a memo called In Event of Moon Disaster.

Fifty years ago, not even Stanley Kubrick could have faked the Moon landing. But today, visual effects and techniques driven by machine learning are so good that it might be relatively simple, at least the television broadcast part of it.1 In a short demonstration of that technical supremacy, a group from MIT has created a deepfake version of Nixon delivering that disaster speech. Here are a couple of clips from the deepfake speech:

Fate has ordained that the men who went to the moon to explore in peace will stay on the moon to rest in peace.

The full film is being shown at IDFA DocLab in Amsterdam and will make its way online sometime next year.

The implications of being able to so convincingly fake the televised appearance of a former US President are left as an exercise to the reader. (via boing boing)

Update: The whole film is now online. (thx, andy)

  1. But technology is often a two-way street. If the resolution of the broadcast is high enough, CGI probably still has tells…and AI definitely does. And even if you got the TV broadcast correct, with the availability of all sorts of high-tech equipment, the backyard astronomer, with the collective help of their web-connected compatriots around the world, would probably be able to easily sniff out whether actual spacecraft and communication signals were in transit to and from the Moon.โ†ฉ


Sony’s Proto-Walkman that Went to the Moon

50 years ago, the Sony TC-50 cassette player and recorder accompanied the Apollo 11 crew to the Moon and back. (Here’s what they listened to.) Ten years later, the company came out with the Walkman, the first portable cassette player that struck a chord with consumers. In this video, Mat of Techmoan shows us the TC-50 and shows how similar it is to the later Walkman. I found this video via Daring Fireball, where John Gruber remarked on the iterative nature of design: “You get to a breakthrough like the original iPhone one step at a time.”


What Neil Armstrong Saw from His Window As He Landed on the Moon

I was away this weekend at a family function and mostly without internet access, so I didn’t get to watch the coverage of the Moon landing for the first time in more than a decade. I also didn’t get to share a bunch of links I had up in browser tabs and now I think everyone is (justifiably) tired of all the Apollo 11 hoopla, myself included. But I hope you’ll indulge me in just one more and then I’ll (maybe! hopefully!) shut up about it for another year.

It’s tough to narrow it down, but the most dramatic & harrowing part of the whole mission is when Neil Armstrong notices that the landing site the LM (call sign “Eagle”) is heading towards is no good โ€” it’s too rocky and full of craters โ€” so he guides the spacecraft over that area to a better landing spot. He does this despite never having flown the LM that way in training, with program alarms going off, with Mission Control not knowing what he’s doing (he doesn’t have time to tell them), and with very low fuel. Eagle had an estimated 15-20 seconds of fuel left when they touched down and the guy doing the fuel callouts at Mission Control was basically just estimating the remaining fuel in his head based on how much flying he thinks the LM had done…and again, the LM had never been flown like that before and Mission Control didn’t know what Armstrong was up to! (The 13 Minutes to the Moon podcast does an excellent job explaining this bit of the mission, episode 9 in particular.)

Throughout this sequence, there was a camera pointed out Buzz Aldrin’s window โ€” you can see that video here โ€” but that was a slightly different view from Armstrong’s. We’ve never seen what Armstrong saw to cause him to seek out a new landing site. Now, a team at NASA has simulated the view out of his window using data from the Lunar Reconnaissance Orbiter Camera:

The LROC team reconstructed the last three minutes of the landing trajectory (latitude, longitude, orientation, velocity, altitude) using landmark navigation and altitude call outs from the voice recording. From this trajectory information, and high resolution LROC NAC images and topography, we simulated what Armstrong saw in those final minutes as he guided the LM down to the surface of the Moon. As the video begins, Armstrong could see the aim point was on the rocky northeastern flank of West crater (190 meters diameter), causing him to take manual control and fly horizontally, searching for a safe landing spot. At the time, only Armstrong saw the hazard; he was too busy flying the LM to discuss the situation with mission control.

This reconstructed view was actually pretty close to the camera’s view out of Aldrin’s window:

Two other things. You can also experience the landing and Moon walk live at Apollo 11 in Real Time. And it looks like CBS News is doing a livestream of Cronkite’s coverage of the landing on YouTube starting at 3:30pm. Nice to see them catching up! :)


Neil and Buzz Barely Got Out of the Infield

Apollo 11 Baseball

With the 50th anniversary of the first crewed landing on the Moon fast approaching, I thought I’d share one of my favorite views of the Moon walk, a map of where Neil Armstrong and Buzz Aldrin walked on the Moon, superimposed over a baseball field (bigger). The Lunar Module is parked on the pitcher’s mound and you can see where the two astronauts walked, set up cameras, collected samples, and did experiments.

This map easily illustrates something you don’t get from watching video of the Moon walk: just how close the astronauts stayed to the LM and how small an area they covered during their 2 and 1/2 hours on the surface. The crew had spent 75+ hours flying 234,000 miles to the Moon and when they finally got out onto the surface, they barely left the infield! On his longest walk, Armstrong ventured into center field about 200 feet from the mound, not even far enough to reach the warning track in most major league parks. In fact, the length of Armstrong’s walk fell far short of the 363-foot length of the Saturn V rocket that carried him to the Moon and all of their activity could fit neatly into a soccer pitch (bigger):

Apollo 11 Soccer

Astronauts on subsequent missions ventured much further. The Apollo 12 crew ventured 600 feet from the LM on their second walk of the mission. The Apollo 14 crew walked almost a mile. After the Lunar Rover entered the mix, excursions up to 7 miles during EVAs that lasted for more than 7 hours at a time became common.


Video of the Complete Descent of the Apollo 11 Lunar Module

The Apollo Flight Journal has put together a 20-minute video of the full descent and landing of the Apollo 11 Lunar Module containing Neil Armstrong and Buzz Aldrin on July 20, 1969.

The video combines data from the onboard computer for altitude and pitch angle, 16mm film that was shot throughout the descent at 6 frames per second. The audio recording is from two sources. The air/ground transmissions are on the left stereo channel and the mission control flight director loop is on the right channel. Subtitles are included to aid comprehension.

Reminder that you can follow along in sync with the entire Apollo 11 mission right up until their splashdown. I am also doing my presentation of Walter Cronkite’s CBS news coverage of the landing and the Moon walk again this year, starting at 4:10pm EDT on Saturday, July 20. Here’s the post I wrote about it last year for more details. (thx, david)


The Apollo 11 Mission in Realtime

Apollo 11 Realtime

Well, this is just flat-out fantastic. Ben Feist and a team of collaborators have built Apollo 11 In Real Time, an interactive presentation of the first mission to land on the Moon as it happened.

This website replays the Apollo 11 mission as it happened, 50 years ago. It consists entirely of historical material, all timed to Ground Elapsed Time โ€” the master mission clock. Footage of Mission Control, film shot by the astronauts, and television broadcasts transmitted from space and the surface of the Moon, have been painstakingly placed to the very moments they were shot during the mission, as has every photograph taken, and every word spoken.

You can tune in in real time beginning July 16th, watch/experience it right now from 1 minute before launch, or you can skip around the timeline to just watch the moments you want. As someone who has been hosting an Apollo 11 in real time thing for the past 9 years, this site makes me both ridiculously happy and a little bit jealous.

I’ve only ever seen footage of the first moonwalk in grainy videos as broadcast on TV, but this site shows it in the original resolution and it’s a revelation. Here’s the moonwalk, beginning with some footage of the folks in Mission Control nervously fidgeting with their hands (skip to 5:18:00 if the video doesn’t start there):

The rest of the video for the entire mission can be found here…what a trove. This whole thing is marvelous…I can’t wait to tune in when July 16th rolls around.


The Biggest Nonmilitary Effort in the History of Human Civilization

Charles Fishman has a new book, One Giant Leap, all about NASA’s Apollo program to land an astronaut on the moon. He talks about it on Fresh Air with Dave Davies.

On what computers were like in the early ’60s and how far they had to come to go to space

It’s hard to appreciate now, but in 1961, 1962, 1963, computers had the opposite reputation of the reputation they have now. Most computers couldn’t go more than a few hours without breaking down. Even on John Glenn’s famous orbital flight โ€” the first U.S. orbital flight โ€” the computers in mission control stopped working for three minutes [out] of four hours. Well, that’s only three minutes [out] of four hours, but that was the most important computer in the world during that four hours and they couldn’t keep it going during the entire orbital mission of John Glenn.

So they needed computers that were small, lightweight, fast and absolutely reliable, and the computers that were available then โ€” even the compact computers โ€” were the size of two or three refrigerators next to each other, and so this was a huge technology development undertaking of Apollo.

On the seamstresses who wove the computer memory by hand

There was no computer memory of the sort that we think of now on computer chips. The memory was literally woven … onto modules and the only way to get the wires exactly right was to have people using needles, and instead of thread wire, weave the computer program. …

The Apollo computers had a total of 73 [kilobytes] of memory. If you get an email with the morning headlines from your local newspaper, it takes up more space than 73 [kilobytes]. … They hired seamstresses. … Every wire had to be right. Because if you got [it] wrong, the computer program didn’t work. They hired women, and it took eight weeks to manufacture the memory for a single Apollo flight computer, and that eight weeks of manufacturing was literally sitting at sophisticated looms weaving wires, one wire at a time.

One anecdote that was new to me describes Armstrong and Aldrin test-burning moon dust, to make sure it wouldn’t ignite when repressurized.

Armstrong and Aldrin actually had been instructed to do a little experiment. They had a little bag of lunar dirt and they put it on the engine cover of the ascent engine, which was in the middle of the lunar module cabin. And then they slowly pressurized the cabin to make sure it wouldn’t catch fire and it didn’t. …

The smell turns out to be the smell of fireplace ashes, or as Buzz Aldrin put it, the smell of the air after a fireworks show. This was one of the small but sort of delightful surprises about flying to the moon.


US Postal Service Unveils 50th Anniversary Apollo 11 Stamps

Apollo 11 Usps

In commemoration of the 50th anniversary of the Apollo 11 Moon landing, the USPS is releasing a pair of stamps with lunar imagery.

One stamp features a photograph of Apollo 11 astronaut Buzz Aldrin in his spacesuit on the surface of the moon. The image was taken by astronaut Neil Armstrong. The other stamp, a photograph of the moon taken in 2010 by Gregory H. Revera of Huntsville, AL, shows the landing site of the lunar module in the Sea of Tranquility. The site is indicated on the stamp by a dot.

These pair nicely with the US Mint’s Apollo 11 commemorative coins.

A Huge Collection of Apollo 11 Press Kits

When Apollo 11 landed two men on the Moon and returned them safely to Earth, thousands of people at NASA were joined in the effort by dozens of companies that did everything from building the spacecraft to providing the cameras for the mission. Each of those companies was understandably proud of their involvement and wanted to use the mission to drum up interest in their products and services. Marketing strategist David Meerman Scott has been collecting the press kits produced by the Apollo contractors and has made them available online for free download in PDF format.

What a trove! Here are a few of my favorites. First is the kit from Fisher, who provided the pens that Armstrong, Aldrin, and Collins wrote with during the voyage.

Apollo Press Kits

The final requirement was to see if the pen could still write after all that torture. NASA required that each pen write 1,653 feet of continuous traces, or for about 4 1/2 hours. The three pens were placed in an automatic writing machine and far out passed the qualifications. The first pen wrote for 54 hours and 50 minutes and 15,346 feet. The second finished after 18,303 feet. The third, writing on a new, highly absorbent paper, still wrote for 7,484 feet.

Fisher still sells a version of the original Apollo 11 space pen.

After the astronauts came back from the Moon, they were quarantined for 21 days to ensure that the crew had not returned with any harmful Moon germs. Stouffer’s, the frozen foods company, was contracted by NASA to provide some of the astronauts’ meals in quarantine.

Apollo Press Kits

A typical astronaut dinner will consist of short ribs of beef, potatoes au gratin and tossed green salad. Stouffer’s has been selected to provide from its retail line a major portion of the entrees and side dishes for the astronauts. Ease of preparation, purity, quality and variety as well as taste and appearance were the main reasons for NASA’s selection of Stouffer’s foods.

Hasselblad provided the cameras for the mission.

Grumman made the Lunar Module, the capsule that carried Armstrong and Aldrin to and from the surface of the Moon.

Apollo Press Kits

I could keep going on these all day. What a terrific resource. Scott, along with Richard Jurek, is also the author of Marketing the Moon, a book about how NASA sold the Apollo program to the American public. (via steven heller)


National Geographic’s Upcoming Documentary on the Apollo Missions

With the 50th anniversary of the Moon landing coming up this summer, the media is about to go into Apollo overdrive. (And I am fully here for it!) So far, there’s been First Man and this Apollo 11 documentary featuring a recently discovered trove of 65mm footage. Add to that Apollo: Missions to the Moon, a documentary series by Tom Jennings for National Geographic. Here’s the trailer:

Engadget has some info on the content of the film:

Director Tom Jennings (who previously documented the Challenger explosion and Princess Diana) is relying on a few uncommon technological tricks to enrich the experience. He’s melding NASA footage with Apollo black box recordings, for example, and is syncing 30-track audio from Mission Control. The aim is to create an “Apollo-era time machine,” Jennings said.

Add an original Hans Zimmer soundtrack into the mix and this could really be something special.


Trailer for “Apollo 11”, a Documentary Based on Pristine 65mm Footage of the Mission

We’re coming up on the 50th anniversary of the Apollo 11 mission, which means an increase in Apollo 11 media. This is a strong early entrant: “Apollo 11”, a feature-length documentary on the mission, featuring “a newly discovered trove of 65mm footage” of starting clarity.

Miller and his team collaborated with NASA and the National Archives (NARA) to locate all of the existing footage from the Apollo 11 mission. In the course of sourcing all of the known imagery, NARA staff members made a discovery that changed the course of the project โ€” an unprocessed collection of 65mm footage, never before seen by the public. Unbeknownst to even the NARA archivists, the reels contained wide format scenes of the Saturn V launch, the inside of the Launch Control Center and post-mission activities aboard the USS Hornet aircraft carrier.

The find resulted in the project evolving from one of only filmmaking to one of also film curation and historic preservation. The resulting transfer โ€” from which the documentary was cut โ€” is the highest resolution, highest quality digital collection of Apollo 11 footage in existence.

The film is 100% archival footage and audio. They’ve paired the footage with selections from 11,000 hours of mission audio.

The other unexpected find was a massive cache of audio recordings โ€” more than 11,000 hours โ€” comprising the individual tracks from 60 members of the Mission Control team. “Apollo 11” film team members wrote code to restore the audio and make it searchable and then began the multi-year process of listening to and documenting the recordings. The effort yielded new insights into key events of the moon landing mission, as well as surprising moments of humor and camaraderie.

This. Sounds. Amazing. The film premiered at the Sundance Film Festival a few days ago and the reviews have been overwhelmingly positive. Here’s David Erhlich writing for Indiewire:

It’s rare that picture quality can inspire a physical reaction, but the opening moments of “Apollo 11,” in which a NASA camera crew roams around the base of the rocket and spies on some of the people who’ve come to gawk at it from a beach across the water, are vivid enough to melt away the screen that stands between them. The clarity takes your breath away, and it does so in the blink of an eye; your body will react to it before your brain has time to process why, after a lifetime of casual interest, you’re suddenly overcome by the sheer enormity of what it meant to leave the Earth and land somewhere else. By tricking you at a base sensory level into seeing the past as though it were the present, Miller cuts away the 50 years that have come between the two, like a heart surgeon who cuts away a dangerous clot so that the blood can flow again. Such perfect verisimilitude is impossible to fake.

And Daniel Fienberg for The Hollywood Reporter:

Much of the footage in Apollo 11 is, by virtue of both access and proper preservation, utterly breathtaking. The sense of scale, especially in the opening minutes, sets the tone as rocket is being transported to the launch pad and resembles nothing so much as a scene from Star Wars only with the weight and grandeur that come from 6.5 million pounds of machinery instead of CG. The cameraman’s astonishment is evident and it’s contagious. The same is true of long tracking shots through the firing room as the camera moves past row after row after row of computers, row after row after row of scientists and engineers whose entire professional careers have led to this moment.

There will be a theatrical release (including what sounds like an IMAX release for museums & space centers) followed by a showing on TV by CNN closer to July.


First Man

I don’t know why I’m so skeptical about First Man, the upcoming biopic about Neil Armstrong and the first Moon landing. Oh wait, yes I do: Apollo 11 holds a special place in my heart, as does Armstrong and his role in the historic landing, and I’m very protective of it. It would be so easy and, in my opinion, wrong to load this story up with unnecessary drama when there’s already so much there in the story, even though it might not be naturally cinematic.

On the other hand, the trailer looks great, Ryan Gosling is a terrific actor, director Damien Chazelle’s previous films are really good (Whiplash and La La Land), and the film is based on the authorized and well-received biography by James Hansen. Ok fine, I just talked myself into it!


Live TV coverage of the Apollo 11 landing and Moon walk

Apollo 11 TV Coverage

In May 1961, President John F. Kennedy stood before Congress and said:

I believe that this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the moon and returning him safely to the earth.

A little more than 8 years later, it was done. On July 20, 1969, 49 years ago today, Neil Armstrong and Buzz Aldrin landed on the Moon, took a walk, and returned safely to Earth a few days later. And the whole thing was broadcast live on television screens around the world.

For the 40th anniversary of the landing in 2009, I put together a page where you can watch the original CBS News coverage of Walter Cronkite reporting on the Moon landing and the first Moon walk, synced to the present-day time. Just open this page in your browser and the coverage will start playing at the proper time. Here’s the schedule (all times EDT):

4:10:30 pm: Moon landing broadcast starts
4:17:40 pm: Lunar module lands on the Moon

4:20:15 pm: Break in coverage

10:51:27 pm: Moon walk broadcast starts
10:56:15 pm: First step on Moon
11:51:30 pm: Nixon speaks to the Eagle crew
12:00:30 am: Broadcast end (on July 21)

You can add these yearly recurring events to your calendar: Moon landing & Moon walk.

Here’s what I wrote when I launched the project, which is one of my favorite things I’ve ever done online:

If you’ve never seen this coverage, I urge you to watch at least the landing segment (~10 min.) and the first 10-20 minutes of the Moon walk. I hope that with the old time TV display and poor YouTube quality, you get a small sense of how someone 40 years ago might have experienced it. I’ve watched the whole thing a couple of times while putting this together and I’m struck by two things: 1) how it’s almost more amazing that hundreds of millions of people watched the first Moon walk *live* on TV than it is that they got to the Moon in the first place, and 2) that pretty much the sole purpose of the Apollo 11 Moon walk was to photograph it and broadcast it live back to Earth.

I’ve been listening to the audiobook of Andrew Chaikin’s account of the Apollo program, A Man on the Moon, and the chapter about Apollo 11’s Moon landing was riveting.1 I’ve watched the TV footage & listened to the recordings dozens of times and I was still on the edge of my seat, sweating the landing alongside Armstrong and Aldrin. And sweating they were…at least Armstrong was. Take a look at his heart rate during the landing; it peaked at 150 beats per minute at landing (note: the “1000 ft altitude” is mislabeled, it should be “100 ft”):

Neil Armstrong's heart rate during the Apollo 11 Moon landing

For reference, Armstrong’s resting heart rate was around 60 bpm. There are a couple of other interesting things about this chart. The first is the two minutes of missing data starting around 102:36. They were supposed to be 10 minutes from landing on the Moon and instead their link to Mission Control in Houston kept cutting out. Then there were the intermittent 1201 and 1202 program alarms, which neither the LM crew nor Houston had encountered in any of the training simulations. At the sign of the first alarm at 102:38:26, Armstrong’s heart rate actually appears to drop. And then, as the alarms continue throughout the sequence along with Houston’s assurances that the alarm is nothing to worry about, Armstrong’s heart rate stays steady.

Right around the 2000 feet mark, Armstrong realizes that he needs to maneuver around a crater and some rocks on the surface to reach a flat landing spot and his heart rate steadily rises until it plateaus at the landing. At the time, he thought he’d landed with less than 30 seconds of fuel remaining. That Neil Armstrong was able to keep his cool with unknown alarms going off while avoiding craters and boulders with very little fuel remaining and his heart rate spiking while skimming over the surface OF THE FREAKING MOON doing something no one had ever done before is one of the most totally cold-blooded & badass things anyone has ever done. Damn, I get goosebumps just reading about it!

Update: The landing broadcast just aired and I wanted to explain a little about what you saw (you can relive it here).

The shots of the Moon you see during the landing broadcast are animations…there is obviously no camera on the Moon watching the LM descend to the surface. There was a camera recording the landing from the LM but that footage was not released until later. This is in contrast to the footage you’ll see later on the Moon walk broadcast…that footage was piped in live to TV screens all over the world as it happened.

The radio voices you hear are mostly Mission Control in Houston (specifically Apollo astronaut Charlie Duke, who acted as the spacecraft communicator for this mission) and Buzz Aldrin, whose job during the landing was to keep an eye on the LM’s altitude and speed โ€” you can hear him calling it out, “3 1/2 down, 220 feet, 13 forward.” Armstrong doesn’t say a whole lot…he’s busy flying and furiously searching for a suitable landing site. But it’s Armstrong that says after they land, “Houston, Tranquility Base here. The Eagle has landed.”. Note the change in call sign from “Eagle” to “Tranquility Base”. :)

Two things to listen for on the broadcast: the 1201/1202 program alarms I mentioned above and two quick callouts by Charlie Duke about the remaining fuel towards the end: “60 seconds” and “30 seconds”. Armstrong is taking all this information in through his earpiece โ€” the 1202s, the altitude and speed from Aldrin, and the remaining fuel โ€” and using it to figure out where to land.

The CBS animation shows the fake LM landing on the fake Moon before the actual landing โ€” when Buzz says “contact light” and then “engine stop”. The animation was based on the scheduled landing time and evidently couldn’t be adjusted. The scheduled time was overshot because of the crater and boulders situation mentioned above.

Cronkite was joined on the program by former astronaut Wally Schirra. When Armstrong signaled they’d landed, Schirra can be seen dabbing his eyes and Cronkite looks a little misty as well as he rubs his hands together.

  1. The book is read by Bronson Pinchot, who played Balki Bartokomous on the 80s sitcom Perfect Strangers. He is a fantastic audiobook narrator.โ†ฉ


The Moon 1968-1972

Apollo 11 Flag

The Moon 1968-1972 is a slim volume of photographs from the Apollo missions to the Moon that took place over four short years almost 50 years ago. The book contains a passage by E.B. White taken from this New Yorker article about the Apollo 11 landing in 1969.

The moon, it turns out, is a great place for men. One-sixth gravity must be a lot of fun, and when Armstrong and Aldrin went into their bouncy little dance, like two happy children, it was a moment not only of triumph but of gaiety. The moon, on the other hand, is a poor place for flags. Ours looked stiff and awkward, trying to float on the breeze that does not blow. (There must be a lesson here somewhere.) It is traditional, of course, for explorers to plant the flag, but it struck us, as we watched with awe and admiration and pride, that our two fellows were universal men, not national men, and should have been equipped accordingly. Like every great river and every great sea, the moon belongs to none and belongs to all. It still holds the key to madness, still controls the tides that lap on shores everywhere, still guards the lovers who kiss in every land under no banner but the sky. What a pity that in our moment of triumph we did not forswear the familiar Iwo Jima scene and plant instead a device acceptable to all: a limp white handkerchief, perhaps, symbol of the common cold, which, like the moon, affects us all, unites us all.


Live TV coverage of Apollo 11 landing and moon walk

Apollo 11 TV Coverage

48 years ago today, the lunar module from the Apollo 11 mission landed on the Moon. Later that same day, Neil Armstrong and Buzz Aldrin stepped out of the module, set foot on the surface, and went for a walk. And the entire world watched them do it. Live.

For the 40th anniversary of the landing in 2009, I put together a page where you can watch the original CBS News coverage of Walter Cronkite reporting on the Moon landing and the first Moon walk, synced to the present-day time. Just open this page in your browser and the coverage will start playing at the proper time. Here’s the schedule (all times EDT):

4:10:30 pm: Moon landing broadcast starts
4:17:40 pm: Lunar module lands on the Moon

4:20:15 pm: Break in coverage

10:51:27 pm: Moon walk broadcast starts
10:56:15 pm: First step on Moon
11:51:30 pm: Nixon speaks to the Eagle crew
12:00:30 am: Broadcast end (on July 21)

Here’s what I wrote when I launched the project:

If you’ve never seen this coverage, I urge you to watch at least the landing segment (~10 min.) and the first 10-20 minutes of the Moon walk. I hope that with the old time TV display and poor YouTube quality, you get a small sense of how someone 40 years ago might have experienced it. I’ve watched the whole thing a couple of times while putting this together and I’m struck by two things: 1) how it’s almost more amazing that hundreds of millions of people watched the first Moon walk *live* on TV than it is that they got to the Moon in the first place, and 2) that pretty much the sole purpose of the Apollo 11 Moon walk was to photograph it and broadcast it live back to Earth.

This is one of my favorite projects I’ve ever done, and it almost didn’t happen this year. I woke up this morning assuming it was just going to work again, just like it had the previous 8 years, but a bit of testing revealed that YouTube had discontinued the API I was using to display and time the videos. I wasn’t sure I had the JavaScript chops to fix it in time for the big show this afternoon. Luckily, I was able to solicit some help on Twitter and as the internet continues to be absolutely amazing, Geoff Stearns fixed the problem. As he said in his tweet, Stearns works for Google and wrote the YouTube API that had been discontinued, which is a bit like Marshall McLuhan popping out from behind a poster in Annie Hall, but instead of saying “you know nothing of my work”, he says “I’m gonna fix this up real quick”. Reader, it took him 14 minutes from saying “I’ll help” to posting the solution, and I’d bet half of that time was spent running to the fridge for a LaCroix and selecting the proper coding playlist on Spotify. So big thanks to Geoff for making this happen today! And thanks also to Brian Seward, who landed a solution in my inbox a bit after Geoff’s.

Oh, and no more Flash! So it’ll work on any modern browser with no plugins. But I tested it on my phone and it still doesn’t seem to work properly there…the video loads but doesn’t autoplay. Something to improve for next year!


Neil Armstrong’s bag of Moon junk

For whatever reason, when Buzz Aldrin and Neil Armstrong left the surface of the Moon after their historic space walk, they collected “a bunch of trash that we want to take back” in a small white bag. Upon their return to Earth, Armstrong put the bag in a closet and there it sat for more than 40 years, until Armstrong’s widow discovered it shortly after his death. Among other items, the bag contained the camera that recorded The Eagle’s landing on the Moon and Armstrong’s first step, which was presumed to have been lost or left on the Moon.

Apollo 11 Camera

As far as we know, Neil has never discussed the existence of these items and no one else has seen them in the 45 years since he returned from the Moon. (I asked James Hansen, Neil’s authorized biographer if he had mentioned the items, and he had not.) Each and every item has its own story and significance, and they are described with photographs in extraordinary detail in an addendum to the Apollo Lunar Surface Journal. But two of the items are especially timely. Both have been placed on display as part of the recently opened temporary exhibition Outside the Spacecraft: 50 Years of Extra-Vehicular Activity.

The first is the 16mm Data Acquisition Camera that was mounted in the window of the lunar module Eagle to record the historic landing and “one small step” made by Armstrong as humankind first set foot on another world.

(FYI, I didn’t test it, but I’m almost positive this will *not* work on mobile…it uses YouTube’s Flash player to show the video. Sorry.)


Neil Armstrong, RIP

Neil Armstrong RIP

Neil Armstrong, the first man to walk on the Moon, died today at the age of 82.

Although he had been a Navy fighter pilot, a test pilot for NASA’s forerunner and an astronaut, Mr. Armstrong never allowed himself to be caught up in the celebrity and glamour of the space program.

“I am, and ever will be, a white socks, pocket protector, nerdy engineer,” he said in February 2000 in one a rare public appearance. “And I take a substantial amount of pride in the accomplishments of my profession.”

A sad day; Armstrong was one of my few heroes. In my eyes, Armstrong safely guiding the LEM to the surface of the Moon, at times by the seat of his pants, is among the most impressive and important things ever done by a human being.

Thanks to Dave Schumaker for the reminder.


New Apollo 11 footage

Due to the Moon’s relative position in the sky as Neil Armstrong started his moonwalk, Australia was able to capture the first few minutes of his descent down the ladder before NASA was able to find a signal. But it was lost until recently; the restored footage will be shown next week at an event in Sydney.


Original Apollo 11 CBS News broadcast

I had so much fun with this last year, I’m doing it again: watch the original CBS News coverage of the Apollo 11 Moon landing and first Moon walk, reported live by Walter Cronkite exactly 41 years after it happened.

I have not done extensive browser testing so it may not work perfectly in your browser. If you run into any problems, just reload the page. Thanks for tuning in.


Apollo 11 slow-motion launch

The view is from one of the cameras close to the engines. The narration is great; you really get a sense of how many things had to be considered to make it to the Moon (like the launch pad paint that burned and charred in order to protect the underlying materials). (via df)

Speaking of the Moon, the LRO snapped a new picture of Apollo 11 landing site from its orbital perch 50km above the surface.
