A couple of years later: Marc and his Friends have restored a complete Apollo Rocket and are flying to the moon :-) Can't wait for the videos on the new module.
We are inflating the Saturn V in my garden as we speak! The seller on eBay said he took it from a functional setup, but did not have the equipment to test it.
I want to see an onboard computer size comparison between the Apollo Mission and the latest ones. Can an IPhone really give you all the 0's and 's that you need to get to the moon?
@@yatessmyrna Since in the AGC restoration series they pretty much emulated a whole comand module on a macbook for testing that should be possible. But it is not only about the computational power, the architecture is also very different to a "normal" PC.

Curious Marc, the gift that keeps on giving! Thanks guys for keeping the spirit of Apollo alive and giving us an appreciation of the hardware. I especially like it when in the comments section someone writes I, or my father/mother or grandparents worked for that company or on that piece of hardware. Bringing these to life is truly a gift. Thanks again!
I just love all of this content! It is so interesting seeing all of this cool old hardware, and even more fun when you bring it back to life all these years later. Thanks, keep up the great work!
Nice flex on the Twist Lite. Even citing the catalog number scheme 😁 Crazy that all this is in the hands of a private collector. "If you strike me down, I shall become far heavier than you can possibly imagine." That's all I could think when you described the weight of the computers vs the landing struts
The content from this channel is amazing!! I love seeing how these old computers and equipment worked!! Really is mind blowing how they came up with this technology in the 60s and 70s and how it was able to communicate from space to earth. Mind blowing the talent from that era.
I've seen pretty much all of this channel . . . this is simply brilliant . . . I worked with equipment that had those panels . . . the pull-twist switches blew my mind . . . completely forgot about them, but was constantly replacing bulbs . . . wow. Thnx Marc!
I've never been that interested in space or rockets and the like, but I enjoy your explanations, the enthusiasm and the teams knowledge. ........ and the desire to fix things.
I do my looms like that with waxed string. They can be found at the tank museum Bovington and at Duxford. No one will ever see them but it made me happy to make then in the original style.
Just think, all that technology, made by hand, made by men and women who thought about it during café breaks, who wrote it down on napkins and then went to their departments and said "I came up with this during lunch", people who thought outside the box, "we don't have anything like that!" / "then we'll be the first!", also, definitely want to see more of the Globus Navigation units, Vostok version was almost entirely clockwork, OKB-1 built a version that was mounted to the wall and then compressed it down to a suitcase, incredible both NASA and USSR worked similar methods when developing new technology!
@12:12 - "I was ignorant about that." What a wonderfully appropriate word choice. One is only ignorant until they learn. It's what drives me day to day.
Wow… this is the third time that I’ve watched the video trying to remember all the amazing collection. Impatience to watch the future series. Love you guys
How cute is that the COMM seat headrest levers have knobs turned out of wood ':D Thanks for this completely crazy mini tour in the mega museum I really hope we'll get to see a fuel cell collab video with Ben!
Just amazing. Would be great to see a virtual tour assembled where you can view all these artifacts from various angles, zoom in, etc. Looking forward to the rest of the series.
This really makes it clearer what marvelous things neede to be built for space missions. It's way more than a flamey chamber, fuel tank and a coke can on top.
@@CuriousMarc I remember Dave from EEVblog making a video about a mechanic calculator from an aeroplane. It was full of gears and specially shaped metal rails for the - probably analog - encoders. It was maybe a similar item but larger and without display. And just found it :D ruclips.net/video/hzGaO4Kdz2Y/видео.html
I don't know if it is tecnically possible without doing to much intrusion to the construction, but it had been awsome to see some pictures of the mecanism.
A bit too coarse of a resolution to be fun as a gps... Make it show ISS trajectory instead? That's basically what it would've shown at some point if it is actual flying hardware.
@Nik Reichel yes I saw that episode, incredible hardware. The astrotracker was an immensely more complicated beast though, and he is missing other main parts, like the optical star tracker itself and the inertial platform. It was an inertial platform navigation system augmented by a automated star/sun/moon sightings for eliminating position and orientation drifts. He has the amazing analog computer with motors and gears for that system.
I was a Titan Missile electronics tech from 1979-1983....I replaced a few MGCs and IMUs while I was there.....we tested them and replaced them but never looked inside one....
CuriousMarc - what an aptly named channel and that makes one insane waiting for the next video. I have never enjoyed hearing a French accent narrate stuff as in these videos. Thanks guys, great channel!
I sense the future holds more FPGA magic from Mike, and Marc strapping some unique-one-of-a-kind historic space hardware to his CNC machine for some emergency diode surgery :-)
Marc, we were just kidding when we said you could recreate an entire Apollo stack. But now you're making us eat our words!!!! :XD This is truly amazing stuff
Skylab was in the funny position that once they had settled on the dry workshop and Saturn V solution, weight wasn't at a premium at all. They had a quite massive early video tape solution, an oven and other luxury. The price for that was a launch on the Ssturn V not a IB. Suddenly they had a huge margin, since a basically empty third stage only had to go to earth orbit. Impossible for a SIB, piece of cake for an SV. And that it worked, as the wet workshop idea was in hindsight completely insane. Possibly the only space mission that ever had that luxury of (relatively) unlimited weight budget. . The Skylab 1 rescue is also a criminally undertold story*, a challenge equal if not bigger than Apollo 13. A massive challenge in an extemely limited amount of time. Only no lives were in danger. *cool book Homesteading Sapce, The Skylab story. By some of the actual Skylab Crew.
as far as I know, the consoles in Apollo 13 were custom made props for the movie, and subsequently reused for the tv show "From the earth to the moon". That console might have been used as a reference maybe, but I am positive you don't see real consoles in the film, at least not in the control room (they are not 100% accurate in the movie, even have a added desk light to them which is not original) I have done lots of research for my apollo console era miniature repro, I would be curious to know more if that console was indeed in the movie.

Also the Integrated System Schematic has some pretty awesome schematics: www.ibiblio.org/apollo/Documents/CSM%20Functional%20Integrated%20System%20Schematics%20Block%20II%20Revision%20K.pdf .

Mike Stewart pointed me to all these docs by the way, he is our grand master of Apollo documentation.
7:40 Regarding the question about the THC, if you rotate it clockwise the control system switches from the primary guidance system to the backup, the Stabilization and Control System (SCS). So if the AGC isn't behaving during a burn or so you can quickly switch to the backup without having to flip switches. This was tested before each major burn.
@@benjaminhanke79 Body Mounted Attitude Gyro. These are rate gyros I believe. Part of the backup system for attitude control, if the AGC or main inertial platform were to fail. Or, as in Apollo 13, if you powered them down... Used in the abort system on the LM too.
Hi Marc: In re-watching this great video, I was wondering about the decision or efforts to revive and power-up the fuel cell(?). I think it would be just amazing to be able to get it operational again and maybe use it as a power-supply for the inverter. Anyway, still just beside myself with your dedication and efforts toward the Apollo program hardware! Thanks and 73...
It just involves getting hydrogen and oxygen under high pressure to interact through a super thin membrane that’s 50 years old while heated to 400F. I can’t think of a single thing that could go wrong… But, agreed, that would be a very awesome project.
@@CuriousMarc well after looking into it, it is worse than I would’ve imagined. First off, there are multiple discs that contain the membranes so all of those would have to be refurbished. Then, you have all of the hardware that would have to in someway be recertified to be able to stand the pressures and the temperatures. Then, for that era of fuel cell, they were only able to get about 2600 hours out of it before it had to be completely rebuilt. Finally, since we’re talking about these pressures and temperatures, I consider the thing to actually be dangerous and not worth it. So, I just don’t think the ‘bang for the buck’ is there; even though it would’ve been a really neat project. However, I still think that either bringing up that inverter after being ultrasonically cleaned or finding another one would be a very reasonable and doable project, since most of the expensive items are probably just fine and still intact, requiring only the ancillary smaller components such as the capacitors to be replaced.
Someone should "invite" them over, throw labequiptment into the room and ocasional some food and just let them rebuild the whole system, working, interactive usable. Hopefully nobody from the smithsonian gets Jellous and kidnaps them over to make all their exhibits interactive and working again :D
Thank you Steve Jurvetson and Marc for this glimpse into a collection I never knew existed
"It belongs in a museum! And it should be functional!" (Thanks so much Steve for sharing your collection.)
The ending of the video made me emotional... It's so pure; Human engineering at its ultimate finest.
