This is the second of three videos which will cover the full mission of astronaut John Glenn and Friendship 7, launched 20th February 1962. This part covers the 2nd orbit and the last Atlantic pass on the third orbit.
NASA film footage, audio and photos taken during the flight.
Audio is taken from the onboard voice recorder.
I have added captions and some of the footage into the video to provide the viewer with a reference. I would also suggest reading the air-ground transcripts while watching.
The next video will cover the 3rd orbit and the re-entry.
All video, audio and photos courtesy NASA.
Orbiter Spaceflight Simulator is used to cover parts of the mission not covered by available video footage.

I always celebrate February 20th as John Glenn day since I was a little boy in the early-mid 60's , also April 12 as Yuri Gargarin days. Both brave men lead the world into the space age, and the modern world we live today , and with hope tomorrow. With God's grace and blessing , and mankind's thoughtfulness into the future for all of us and the world
Thank you John Glen for the ride. Never knew all of the problems that you encountered and had to deal with and how you ever mad it back home only God knows!!! What a Miracle ride!! Rally enjoyed listening to the whole journey, as God has now called you home may you enjoy exploring the rest of the Universe throughout Eternity!!! THANK YOU AND WILL DONE SIR!!!
Knew about the fireflys and landing bag debacle, never knew he was having so much trouble with attitude control. Nulling those rates manually can be very taxing after a while, eating up thruster juice. That was some real flying by the Mig Mad Marine.
Thank you for posting. I grew up in the Gemini/ Apollo era. Your work is much appreciated.
Godspeed, John Glenn 1921-2016
Born in 1953, Glenn and all Mercury-Gemini-Apollo Astronauts will always be my heroes and examples. Deepest respect and admiration for Gagarin and the Cosmonauts of the same era.
Thank you Thank you Thank you Thank you...I have been looking forward to this!!!!
As always...appreciate all your hard work!!
thanks for this, very interesting. And thanks for the discussion of fly by wire. I've read several, and between you two, it's the clearest it's ever been to me!
you are exactly correct....then the servo/actuator has a resolver (counts the pulses) and then sends the position (feedback) back to the control display so that the operator (astronaut) also knows the position of the servo/actuator.
1:35:10 Gus Grissom: "Yea verily, Sonny!"
We get it, you are friendship 7 the only capsule in orbit!
At 1:10:05 they give him the warning that Glenn said he never got, that his landing bag might have been deployed. Granted, they said they had no indication of this, and while in space for the first time, you might not be able to put those two things together. Of course, after the fact, we know it was a malfunction on the indicator and his landing bag was not deployed.
*****
Yes, but numerous times afterward, Glenn attests to them never informing him of the nature of the malfunction, even though we can hear it plainly on the transmission.
When he was in the dark was the whole cabin illuminated or just the control panels?
He had lights in the cabin

Thanks! 👍
Glenn keeps referring to a SQUIB being armed, what is that?
JG ! the outer space legend !!
you must take poetic license to demonstrate the images which a viewer cannot see. Very well done !!
The simulation of the window, is it a simulation of exactly what John Glenn would see in the capsule? That distorted fishbowl look of the Earth?
It was what I could see on the simulation - you would have to ask John Glenn if thats what he saw...regards LM5
***** Yeah I thought exactly that after I hit post comment. Thanks for the reply! :)
There were two different representations. One was the actual window and the other was the view through the periscope, which has the distorted parabolic view as function of the reflectors and lenses.
As depicted in the book "The Right Stuff", Glenn seems to spend most of his time trying to acquire signals from the various ground based CAPCOMs. It's interesting to compare this flight with later Gemini, Apollo and Shuttle missions where all CAPCOM dialogue goes through Houston and all of them are astronauts. I'm trying to find out how many of the Mercury 7 were CAPCOMs on this mission: Carpenter at Canaveral and Cooper at Muchea in Australia but did any of the others?
Hey are yiu some kind of a "NASA Insider" to know that Scott Carpenter was the CAPCOM at Cape Canaveral and that Gordon Cooper was the CAPCOM in Australia?
@@steveburrus9347 More likely he either read a book or watched "The Right Stuff". This is all common knowledge.
As I recall, Both Carpenter and Alan Shepard were at the cape - Shepard was the primary CapComm throughout the mission; you only hear Carpenter just before launch (as his back-up) with his 'Godspeed John Glenn'. As far as others - Cooper was in Muchea Australia, Schirra was in California. I thought Deke Slayton was at one site somewhere, but not sure where. Not sure where Grissom was.
Try reading "This New Ocean" for a history of the Mercury program.
@@ajankowski2 According to "This New Ocean", Grissom was in Bermuda. Slayton isn't mentioned in the chapter on Friendship 7.
Over a year ago, I wrote an instrumental track honouring the Friendship 7 mission. Track can be heard here: ruclips.net/video/HIEcEcLsbuI/видео.html 🎶
What were the particles that John was observing during sunrise?
According to wikipedia, 'ice particles shaken loose from the spacecraft's exterior'.
If you haven't found the answer yet, they were small pieces of ice that formed from condensation on the outside of his spacecraft. As he underwent different temps (such as the sunrise), the ice would break off and float around the craft.
@@2plus3is4 They were droplets of urine that he had flushed overboard. Later astronauts would call these "the Constellation You-rine"...
EDIT: There is no conflict with the "ice particles shaken loose from the spacecraft's exterior" explanation; the urine dump overboard didn't go straight out and form droplets- it first froze right at the exit orifice and formed a "yellow popsicle" which then slowly broke up into particles as the vacuum caused sublimation. The only conflict with the previous notes is that the ice didn't come from "condensation"; it came from liquid cooling rapidly in the vacuum and going directly from liquid to solid- no "condensation" process involved.

Who’s Roger?
is this suppose to look real? or is it just something to look at while we listen to the audio?
Did you ever figure it out?
I hear a lot of "read you loud and clear" when transmission is incredibly poor. I wonder if they were humoring each other half the time, Oh, he does say "read you loud, but not clear" just as I was typing that
My gods, it must be so frustrating to keep losing comms like that
I never realized how much talking there was on these early flights. It is hours of non-stop communications, all under difficult radio conditions. If I was Glenn I would be thinking - give me a break guys and shut up for awhile!
Mr. March I agree. I've heard it claimed Cooper did ignore the ground some but I'm not sure how much of that is true or not. He did a great job of landing though! Apparently that led to the flight directors giving the astronauts a little more latitude. I'm not 100% on that.
@@marshja56 Don't forget- this was THE FIRST TIME they tried out the orbital com network. It got better fast.
These guys were used to difficult radio conditions, right? I mean, I'm not saying I know how they work, but I have a little experience here, because I'm an amateur radio operator. Those older radios also have fewer systems to clear things up. Sometimes, the filters and helper modules and amplification actually distort weak signal transmissions; the folks using older comms gear would not have to fight their equipment to hear things in the same way. Honestly, some of the transmissions were a little hard to read, but most, the vast majority, were easy enough to copy. It would have been even easier with a headset on. I'm just using my phone's speaker setup.
Also, the transmission types were pretty clearly delineated, right? I mean, you have requests for activities in the plan or sequences of numbers for retro action. Suppose you miss a phoneme out of the number four. Suppose it comes out as "f*r". You'd know that the only word it could be is "four," because that's the only set of word parts that makes sense. That's also why they do a lot of copy and confirm, where someone reads something important and the other person reads it back to double check.
I do think that the later addition of the telemetry tone, the beeps at the beginning and end of transmission, probably helped a lot. Having to say "over" isn't a big deal, but it's another chance to slip up or mishear.
I think that Mr. Glenn and many subsequent astronauts probably don't mind the chatter as much as we would.
There are two main reasons for this hypothesis:
First, and most importantly, consistent communication is a way to test psychological responses. It gives a record of clarity of speech but also clarity of thought. Communication is a pretty mentally intensive task. Abnormalities in communication can show a variety of types of altered mental state, not least of which is stress. That makes the reports from the astronauts all the more necessary.
The second reason is also mental, but it's more abstract. The Mercury astronauts were utterly alone in a way that is probably incomprehensible to anyone else, even later Gemini and Apollo astronauts. Perhaps the Command Module pilots in the flights where the LM landed experienced something similar, but these Mercury guys had the potential to experience solitude at a level that's just wild to consider. I believe, though I can't confirm, that having this communication with the ground helped keep them grounded, as it were. They were separated in distance and perspective from their arthbound counterparts but were not utterly remote from them.
To be honest, I wish I knew more on the subject. These are just my thoughts, little more than educated guesses.
