Just read Ken’s blog…..what an amazing combination of extremely talented, dedicated and tenacious folks Marc and his team are! The pool of talent that seamlessly meld into Marc’s technology challenges and the passion they share in each project and indeed their stage of the project is infectious. The amount of historically important technology that would otherwise not have be restored to its original working condition for prosperity is amazing. The skills and knowledge that currently exist with the passionate desire to locate, acquire and restore important historically rare equipment is truely remarkable. Equally so the way Marc pulls this all together and shares the experiences as though you are in the basement with him and the talented team of merry engineers.

I don't understand the negative comments about Russian space hardware - not engineers obviously.

What makes these devices even more amazing is the fact that they have to work after a few minutes of vibrations and 7g overload.

[@535phobos]

I dont think the Soyuz pulls 7g at any point. Maybe the landing, but at this point the computer isnt needed anymore.

[@vantuz8264]

@@535phobos Possible. I might've stumbled upon a bad source. Some claim the overload during launch is 1-7g, other say 4g. The most reliable source i found after your reply is an official video of modern Soyuz launch with telemetry. It shows 4g at the end of stage 1. watch?v=UNlglX8IiFo However, that was about modern Soyuz. During the Gagarin's flight the 3rd stage shut down half a second too late and that gave the craft 22m/s extra velocity. That's 4.5g of acceleration when Soyuz only runs at 3g. So acceleration could've been higher at other points as well. Maybe not 7g though. Still, even 4g with vibrations is not insignificant.

The Globus is a beautiful machine. It’s literally hardware, and pretty impervious to unexpected flaws. The main limitation is being locked into one immutable task. There is no chance for an elegant hack such as the one which saved the Apollo 14 LM descent by patching around sensing of the short circuited abort button. … not that a hack would likely be needed in the context of Globus’s operation.

[@YassineKAOUANE]

[@wtmayhew]

I’m trying to decide if that solenoid clanking would be reassuring in its constancy or it would quickly drive me crazy. The latter. 😊

[@CuriousMarc]

Apparently the earlier. They used the clicking as a confirmation that the capsule had separated properly, as the separation triggered the start of the Globus. I suppose it must have been much quieter with the cover on and behind the thick control panel.

[@awatt]

Some nuclear power plants broadcast a click similar to this to let everyone know that the intercom is working and that there are no alarms.

[@wtmayhew]

@@CuriousMarc Thank you Marc. And thank you for your work preserving engineering history.

[@wtmayhew]

@@awatt I never thought about it before, but I had an office in the back of a computing equipment platform room and there was an annunciator and strobe for the Simplex fire alarm in there because the machine noise drowned out the unit in the hallway outside. The speaker emitted a constant sort of digital grinding sound with a faint sound of the fire tone in the background. I chalked it up to lax design, but perhaps that was intentional verification the thing was functional. It was irritating enough that I played a radio at low volume to cover it up. In a similar vein, a Vax 11/750, one of the machines I cared for, had a big red fault light on the front. The light was kept lit a little bit constantly to verify it wasn’t burned out. The only problem was that Digital’s idea of lit a little bit was still pretty bright and more than once I spooked myself glancing over and thinking the fault light might be on.

Thank you for the interesting material and congratulations to both gentlemen for their inquisitiveness. By the way - have you thought about how the engineers at CCCP came up with it. I am writing from Poland and we have encountered various Soviet devices here many times - they were always built differently than those from Western Europe and the USA. It's a different philosophy and way of thinking. The devices work, but they are quite difficult to repair. Greetings to Russian engineers! Привет российским инженерам!

[@jta3556]

Facinating…. 🤯

[@paulw3182]

Ken is the god of reverse engineering!

[@davepost7675]

I'm curious how exactly this was used in flight. I imagine they would place the globus in landing mode and when the landing point gets to the desired landing zone, they would initiate the deorbit burn.

[@LongTran-em6hc]

That's it.

[@CuriousMarc]

Exactly.

[@diogom612]

To expand on this a bit, mission control would send them the various landing opportunities for each day. They were sent the orbit number, the time for the burn, and the landing angle (ugol posadki), and it's this angle that they input into the instrument to use in landing mode. This angle would depend on the orbital altitude.

[@carldagroundskeeper]

9:55 Was just thinking, I'm pretty sure at least 1 Mercury spacecraft had something similar to this gadget :D Thanks for sharing this!

[@CuriousMarc]

And you’d be right! There was an American version of the Globus too used in Mercury! And it was a wind-up instrument! I think used for the few early or suborbital flights only, so it’s exceedingly rare. The Globus on the other hand was used from 1961 to 2002, so gobs of them have been produced.

[@volo870]

The markings on the ball make it seem that it is just a shop-purchased school globe - it indicates the year, the scale, even major shipping routs, which wouldn't be useful in space, but was marked in all geography textbooks back in the time. Am I correct to assume that Soviet and US borders are actually hand-pained with a red sharpie?

[@zyeborm]

If you have to unexpectedly ditch in the ocean I'd probably pick near a major shipping route given the choice.

[@volo870]

I see. Since the "Globus" ball has no hole in the pole, I'd say is is purpose-made, but delivered from a civil globe factory. Mercury Program Earth Path Indicator, on the other hand was indeed bought in a corner shop - it even has a hole in the pole, where the axis used to be!

I find your (necessary) expertise in things electronic fascinating and unreachable (to me), insofar as the _black arts_ necessary to revive these old _doodly-do_ space-boxes. I note from the Soviet engineers a lack of sensitivity to considerations of human-machine interface. Can you imagine living in a spherical refrigerator for days, surrounded by slow but sure death, relying on a mechanism the cosmonaut cannot turn off, going _clack-clack-clack_ until s/he would want to breathe vacuum to end the duress, if the mission were long enough?

About the "old" instrument: in an documentation about russian space program and the sojuz they said (if I remember correctly) that the sojuz hasn't changed much over the years, because the russians are quite pragmatic. If it works, why change it and create new problems?

[@MichaelSolovyev-l2y]

It is not the only reason, to be honest. The bureaucratic procedures to confirm that the new equipment was reliable enough to fly into space were very tedious (and largely meaningless). So, why do something if you can do nothing? But when it was necessary, they worked as hard as they could. A good example is the development of spacesuits for the Soyuz-Apollo mission

[@H0mework]

The world changes. There was nothing "wrong" with Stradivarius violins. If you're missing components you use current components.

[@1djbecker]

But this device only marginally "works". It's not a general navigation instrument. It's a map display that shows what should be happening if the craft is on the nominal flight path, limited to a circular unperturbed orbit at a single fixed inclination. It's sole degree of freedom is a minor correction for the altitude (orbital period). Even for that it requires two adjustments, with the second being the externally calculated angle of the landing point. "It's simpler and just as good" can sometimes be true, but often it's just a coping mechanism. This is a beautiful instrument and a wonderful piece of history, but it was a dead end. It wasn't going to get the soviets to the next level of space travel.
