The Apollo Guidance Computer, Part Two: David Scott

[@TimGreeningJackson]

What an absolutely remarkable man. And so humble and humorous with it. Inspirational.

[@ynp1978]

The lesser person when faced with someone of superior intelligence will often express their jealousy and discomfort by claiming the person is arrogant and or stuck up.

[@dks13827]

Dave Scott is quite a man !!! Thank you, Dave.

[@wcottee]

The Apollo astronauts are a lost breed; smart, brave, skilled. Hopefully we can find men and women like them today.

[@brianarbenz1329]

My favorite Apollo astronaut.

[@youreale]

Amazing talk, thanks for posting.

How could someone dislike this video ?

[@neveniusvondubowatz7705]

Lovell, Swigert and Haise ;)

[@joedmac78]

I thought it was really good. I like the evolution of the rendezvous techniques and how it could be done on the back of an envelope that's awesome

[@AlainHubert]

After listening for 35 minutes to this very interesting man reminiscing about his career and the technology that evolved over time, is there any doubt in anyone's mind that we did go to the moon several times ?

[@neilbishop1686]

Six complete operational landings is many more then "several"....

[@AlainHubert]

@@neilbishop1686 "Several" usually means many more than one AFAIK?

[@pedrodiaz5540]

David Randolph Scott, his middle name is because he was born Randolph Air Force Base, San Antonio Tx. Bright and skilled Astronaut.

[@Dolores5000]

David Scott rules!!

[@josephstevens9888]

The other astronauts used to say if NASA ever made an astronaut recruiting poster, it would feature Dave Scott.

[@James_Bowie]

What a contrast to Eldon Hall.

[@erichaynes7502]

Just think it took basically the entire brain trust of the U.S. to make the AGU an incredible technological success!

[@pedrodiaz5540]

Excellent

[@tijnarbrd]

Respect 🙂

[@Dolores5000]

So daam cool! and beautiful

[@pjimmbojimmbo1990]

Sounds very personable here. Maybe the shame of the stamp scandal humbled him a bit

[@tedpeterson1156]

Did his flight do anything that other flights did not, particularly?

[@pjimmbojimmbo1990]

@@tedpeterson1156 I don't know, about the Flights prior, but I'm sure 16 and 17 were clean. Even Jack Swigert who was supposed fly Apollo-Soyuz got caught up in Stampgate

[@stefanogrillo6040]

i complain to be a pilot i need to be passionate and great skill.

Here in the Year of Our Lord A.D. 2022 I'm patiently waiting for America's manned space program to escape the 1960s. /geo ex machina

Right out of "Central Casting"

Yeap, a good looking well spoken guy.

[@bobrunge7594]

Just an ordinary guy that went to the moon. Smart? Yeah… but he’ll never tell you that.

[@pascalxavier3367]

Because, what happened in the descent of Apollo 11 was not a computer failure?

[@pfilippone]

The computer didn't fail. They later found out they had left something on that was causing the computer to get overloaded. This caused the computer to give a program alarm, then the computer reset itself. But due to the great design, after the reset it picked up and continued to fly the vehicle. If it didn't recover like it did, they would have had to abort the landing.

[@pascalxavier3367]

@@pfilippone And why would have they left this?

[@pfilippone]

@@pascalxavier3367 Wikipedia's Apollo 11 article says: "During the mission, the cause was diagnosed as the rendezvous radar switch being in the wrong position, causing the computer to process data from both the rendezvous and landing radars at the same time." This overloaded the computer, but thanks to the advanced design, it recovered from this and it was able to continue to do the descent and landing.

[@pascalxavier3367]

@@pfilippone I know what Wikipedia says; but those who write in Wikipedia don't know everything. The data switch would have been put in a position in which the radar was not just sending data, but fast pulses which had nothing to do with normal radar data, pulses which were coming from two dephased high frequency sources; in other words, the computer was counting pulses it should not have counted, pulses which were completely irrelevant; moreover, these pulses are never directly counted by the processor in other systems, but by electronic counters of which the count can be read by the processor with an I/O operation. If things had been normally done, these fast pulses, which were completely irrelevant, would not have overloaded the computer, which would just have seen that it was receiving abnormal fast pulses, and could then have issued an alarm clearly showing the problem. www.angelfire.com/moon2/xpascal/MoonHoax/Apollo14AbortFix/1202Alarm.HTM

[@pfilippone]

@@pascalxavier3367 OMG all that explanations to say that this means the moon landing was fake? Give me a BREAK! Like all computers, there was a bug in there, they resolved it by keeping the rendezvous radar off in future missions. You said it was a failure, but the computer did do its job in the end.

*Summary of this talk:* 40% Small anecdotes 40% Hyperbole 19% Broad theoretical ideas 1% Incredibly incomplete picture of Apollo guidance computer specifics

[@larrysmith6797]

And yet he walked on the moon. Who the fuck are you?

[@markbell9742]

Larry: My level of Incredulity is beyond words; you got it right.

[@markbell9742]

APR: Yes, let the Engineer (Part 1) burn through the Nuts-and-Bolts and let the Astronaut (Part 2) wax poetically, with comic relief, peppered with hyperbole and some detail. I smiles through the entire 35+ minutes. Cheers, Mark **********************

Any other links to Dave Scott interviews on KZbin?

[@mikeess2521]

Its strange how NASA spokespeople are always making jokes about the whole thing.

[@oscarin13]

It's called having a sense of humor.

[@mikeess2521]

Oscar Rincón Haha 😁😁😁

[@mikeess2521]

Oscar Rincón Space is a joke... agreed!

[@oscarin13]

If we were in the Middle Ages, your statement wouldn't be ridiculous. But we aren't, so your statement is ridiculous.

[@mikeess2521]

Oscar Rincón Are you trying to make a joke?
