55 years ago today, on July 20, 1969, Neil Armstrong & Buzz Aldrin landed on the Moon and went for a little walk. For the 16th 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 — 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 — the 1202s, the altitude and speed from Aldrin, and the remaining fuel — and using it to figure out where to land.

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.

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 — it’s too rocky and full of craters — 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 — you can see that video here — 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:
You’ve heard by now that it’s the 50th anniversary of the first humans landing on the Moon. On July 20, 1969, 50 years ago today, Neil Armstrong & Buzz Aldrin landed on the Moon and went for a little walk.

I wrote a bit last year about what to watch for during the landing sequence.
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):
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.
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.

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 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”):
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 — 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 — the 1202s, the altitude and speed from Aldrin, and the remaining fuel — 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 — 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.
The book is read by Bronson Pinchot, who played Balki Bartokomous on the 80s sitcom Perfect Strangers. He is a fantastic audiobook narrator.↩
Q: Is there any experience on Earth that even compares slightly to having been on the Moon?
A: My first words of my impression of being on the surface of the Moon that just came to my mind was “Magnificent desolation.” The magnificence of human beings, humanity, Planet Earth, maturing the technologies, imagination and courage to expand our capabilities beyond the next ocean, to dream about being on the Moon, and then taking advantage of increases in technology and carrying out that dream — achieving that is magnificent testimony to humanity. But it is also desolate — there is no place on earth as desolate as what I was viewing in those first moments on the Lunar Surface.
Because I realized what I was looking at, towards the horizon and in every direction, had not changed in hundreds, thousands of years. Beyond me I could see the moon curving away — no atmosphere, black sky. Cold. Colder than anyone could experience on Earth when the sun is up — but when the sun is up for 14 days, it gets very, very hot. No sign of life whatsoever.
That is desolate. More desolate than any place on Earth.
