How Can Soyuz Reach The Space Station In Only 3 Hours? 

I literally LOL'd!

I was thinking it and then he said it. I spat my tea down myself...

What? In 4 hours I can reach the other side of the country with public transport.

Its technically 100% glitchless

@@quantumx9729 do you have proof that they weren't using glitches (for example footage of the entire flight)?

@@Magnedyne Starts sweating nervously*

New strategy, if your impact velocity is high enough that parts of the two spacecraft are bonded together by impact welding that counts as a successful docking

That wouldnt bee 100%tho

LOL

Gehteuch Nixan it do be like that

I use MechJeb. The ability to launch directly into a rendezvous so your circularization burn also nulls your relative velocity to the target when you're close to it (sometimes a little too close) has been a part of MechJeb for a while now. Of course, the fact that the game just out-and-out tells you your orbital parameters (updated every physics frame, which with a green MET clock is 60fps) makes the execution of such feats quite easy once you know which buttons to push (and not push). Tell you what, MechJeb almost makes fueling a mothership with 10 fueling flights bearable. Almost. It's still not bearable for me (I'm impatient) and because of that, I build my fuel tankers MASSIVE so that I only need to make a very few refueling flights for anything worth launching. Like many others, I send things to Minmus to get docked together and fueled, as that's effectively Kerbin's gas station. You're basically guaranteed to have an ore hotspot in one of the flats biomes which makes landing easy. Minmus gravity is only a few thousandths off of 0.5m/s^2, which puts it right in a sweet spot where there's enough gravity that you don't have to worry about bouncing off, but not so much gravity that it takes a lot of engine power to get to orbit (not even 200m/s to get into low Minmus orbit of 15km circular, and due to Minmus' low gravity if the craft can accelerate at 1.5 m/s^2 (Kerbin TWR ~0.15) you'll have plenty enough thrust to be getting into orbit of Minmus easily (that's a Minmus TWR of 1.5).

I was expecting them to do bunny hopping in reverse and some clipping bugs

Yep we did.

And slow enough for free delivery

not the quickest delivery, but still in appropriate range.

When Blue Origin starts flying, will they offer Prime delivery on the ISS?

@@michaelfixedsys7463 sounds like a win-win to me. Especially to save on the $5000+/kg cost to get it to orbit.

@@moosemaimer Probably not

Pulled it off on the first orbit without MechJeb ;)

@@adamk203 Direct launch to rendezvous is SOP, at least in low orbit.

mechjob can do it while circulizing the orbit.

MechJeb has the rendezvous but I beat it on docking finesse. XD

Try it from a launch site which isn't on the equator...

A wise use of time

Now you have to wait for 23h46m52s Or turn your bed 1.2 arc seconds anti-clockwise

Gosh its like half two for me and i just started the video So relatable 🤣

Great minds think alike? Laying in bed...ohh space!

Ahem SPACEX DID YOU FORGET ABOUT SPACEX

Could the Soyuz reach the ISS if it launched from Florida? The ISS, in terms of orbital inclination, is perfectly positioned for it, and there is a reason for that.

@@rbrtck yeah, the reason is that if the inclination was even 1 degree lower the Soyuz would not be able to reach the ISS at all, and if it was 1 degree higher there would be an unnecessary loss in useful payload across all the vehicles supplying the ISS.

"five times" I'm counting four. 1. The Apollo-Shuttle time gap. 2.& 3. Two brief suspensions in Shuttle flights for study after each of two separate fatal Shuttle accidents. 4. The Shuttle-Crew Dragon Time gap. The Soyuz vehicle was first launched in 1967, in the middle of the Apollo program. The Soviets were, of course, the first to send a man to orbit, but previous launches were with earlier vehicles. The Russian space program has afforded mostly continuous manned access to orbit from Gagarin's orbital flight in "Vostok 1" to the present day and pioneered orbital space stations. That means there was at least one more time that Russian vehicles provided the only manned access to space, but not Soyuz.

@@digitalnomad9985 Apollo did not fly with crew onboard until 1968; Gemini's last launch was 1966. Therefor, there's a small gap in there for Soyuz to take. Technically you can argue that the last gap isn't shuttle-Crew Dragon, but actually Shenzhou 11-Crew Dragon, a shorter gap of 4 years where Shenzhou seems to not be launching due to a lack of in service Chinese space stations to launch to. But yes, that does appear to be 5 gaps. Maybe 4 if you want to get rid of the last one.

Yes, TORU is a manual back up rather than another automated docking system.

Also, did they move the production sites for KURS? Because one time I said it was made in Ukraine and some russian nationalist started to insult me 😅

Read the terrific book Dragonfly about Mir including the fire and the Progress collision. Terrifying, engrossing, and revealing of how "seat of the pants" the Russians were in their approach to space.

They tried to beat the Kurs-less% record

@@Valery0p5 According to Wikipedia "After the dissolution of the Soviet Union in 1991, the Kurs system became the property of Ukraine; its manufacturer became a competitor in the space launch business with the Russian Federal Space Agency (RKA)"

Actually you can stretch your legs in the Soyuz spacecraft. Crew can move from decent to orbital section, toilet is available as well of course.

It has the same meaning in polish. 'To stretch legs' is synonym of 'to die'.

In Russian there are two different words for that. "протянуть" - this one is the part of idiom. And "вытянуть" which is means literally stretch.

It explains the legroom in a запорожиц...

In czech, it means to "Push through something", like a small hole

If it ain’t broke don’t fix it seems to be their mantra

Me too, I guess at the end of it all, having too little legroom simply screams for a really short ride as possible!

Ha ha oh yes!

🤣🤣🤣

I would say Challenger is more spectacular.

If you're not docking with your first stage still lit, are you really even docking?

@@jttech44 Look at Mr SSTO here flexing on da haters

@@jttech44 Jesus....

Psh, who needs RCS when you can rely on completely overpowered reactions wheels?

@@argh1989 Won't help you translate

If you've got a few teraflops under the hood, sure. But it's not enough that computer is fast, it must also be reliable, and modern desktop computer hardware is anything but. They're still flying 8 bit machines because that's basically the only thing that proved itself to be capable of controlling real physical hardware.

@@michaelbuckers SpaceX shows another approach is possible: multiple redundant computers all checking each other. Allows you to exploit good computers while still ensuring reliable computation.

@@dsdy1205 Haha yeah no that's not how it works. When there is a hardware or software problem, they all have it, they all make a bad calculation and they all agree with each other. And if there's a program crash, they all crash simultaneously. Having redundant computers is for things like physically damaged circuits and cosmic rays flipping bits in the computer memory causing unrecoverable errors, it does nothing about inherent flaws of the machine.

@@michaelbuckers There is a little problem with your hypothesis: ISS runs on 32bit CPUs (80386SX). The russians use 32bit SPARC in their module DMS-R. As does Falcon (newer x86 CPUs). New Horizons also uses a 32bit RISC processor from 1988. Also: Radiation hardened hardware is not even required by NASA for the ISS (google "Dragon's "Radiation-Tolerant" Design").

Dean Su Redundancy is a double edged sword. Extra complexity may itself become a source for errors. And anyway if you just copy a single computer many times they will still all go down from the same software error. So, three different manufacturers/dev teams? The cost will be insane.

@@bluemountain4181 hell yes

I remember reading that in China the most important feature car buyers look for is rear-seat legroom... How big are their space capsules?

If you have to put up with it for less time then the discomfort matters less.

That's why Gemini capsules are so cheap on the used spacecraft market. No legroom, and you always bang your shins entering or egressing via the hatch.

@@vibrolax Ah, yes. Gemini was the no-helmet-wearing Harley Davidson of spacecraft. No meaningful escape system bolted on explody rocket choc full of hydrazine and nitrogen tetroxide, but is sounded cool starting up. And it had ash trays.

@@Miata822 NASA did spring for the less-explody upgrade package for the Titan II. I don't think they had to use the warranty even once.

The ISS has an escape pod system.

@(S)-Riley Dunn That's what an escape pod is..? The ISS always has enough docked pods to de-orbit all personnel onboard.

@@rockspoon6528 Yes, they are the same spacecraft they arrived in though.

Yeah but during an emergency your launch window would probably be shit

Yeah, if they can foresee the emergency about half a year earlier to start building a Soyuz, or in case they happen to have one ready, a couple weeks to put ISS into the rendez-vous orbit...

@@davidanalyst671 haha bravo

It was perhaps not intended as a pun, but a pun it is nonetheless.

Anyway, come on now, no plural.

I was wondering about this. Is there a difference in delta v to get to ISS from Russia vs USA?

@@BlakeFlood yes. Due to Baikonaur being on a higher inclination, the rotation of the earth doesn't give it as much of a boost. This gives it more of a benefit for launching to high inclination and polar orbits, like the ISS, but less for equatorial and lower inclination. Since florida is much closer to the equator, that gives them a big boost when launching eastward, but this also makes it harder to launch into high inclination orbits. This is why if you look at rockets flying out of the US they often have significantly less payload in polar orbits.

@@BlakeFlood Absolutely. The Falcon 9 and other boosters that carry spacecraft to the ISS have to muster quite a bit more performance just to get to the ISS, and it's not just because some/all of the spacecraft are larger and heavier. The ISS was placed in the orbit it was so that the Soyuz could actually reach it, and this makes it harder on everyone else. If the Russians wanted to launch the Soyuz spacecraft to the ISS from Florida, for example, they would have to use something like the Proton (which I wouldn't recommend for other reasons).

its not designed when ISS was basically launched from Baikonur Cosmodrome

@@imanalfarizi6214 The first module was launched from Baikonur. The vast majority of the modules and components were launched from Florida in the cargo bay of the Shuttle.

Yeah. I’m always like: “they’re probably dead rn”

That system has been used with European ATVs (when they were a thing of course). And they practice a lot. A big problem in MIR times were there was a short blackout space due to the way TORU antennas were mounted. Normally it's not a problem as alignment is done outside of that space, but in that case it was, and so operators could not see that spacecraft was out of alignment until it was too late.

The Kessel run is through an asteroid belt with numerous paths of varying safety and skill. It makes more sense than you think.

If you assume all hyperspace drives travel at the same speed, the only way to get from A to B faster is to take a shorter path. Thus 12 parsecs is faster.

Have people still not seen the original script? "Obi-Wan rolls his eyes at this obvious misinformation" is right there!

Michael Fixedsys a 12 parsec long asteroid belt would be like 36 light years long. Also, asteroid belts are mostly empty space so you’d likely never need to even avoid many if any obstacles.

@@seanbeadles7421 The Star Wars universe has had FTL space travel for the majority of their history. While in nature that would be the case, it's entirely possible that this asteroid belt is artificial, and is close together and significantly faster due to miningoperations, warfare, or even terraforming.

Plenty of time to press their clothes and enjoy an inflight snack ;-)

Hm, wounded why

@@andmos1001 because Ukraine took offense at Russia and imposed sanctions for the fact that Russia did not come to the war that Ukraine declared to it. ) But seriously, in Soviet times, dozens of enterprises that are now located on the territory of other States took part in the production of the Kurs system. And these foreign enterprises have now either ceased to exist or are no longer able to produce components of this docking system. Well, or for political reasons, they stopped supplying their products to Russia. Therefore, Russia made a difficult and expensive decision to transfer ALL its military and space products to use only Russian parts. This means that a lot of things had to be developed from scratch. And I am glad that Russia is successfully coping with this.

@@santalex1982 it was sarcasm of why they did not use Ukrainian parts.

And, by the way, it was not designed in Ukraine from the start.

@@santalex1982 "Ukraine took offense at Russia and imposed sanctions for the fact that Russia did not come to the war that Ukraine declared to it" fuck you, dude.

Straight up and rendezvous over launch?

this is difficult, ISS needs to be like Agena Target Vehicle to do direct ascent rendezvous

Anti-sattelite missile developers are working on it

@@rossMoHaX but anti-satellite missile intend to crash it, not to rendezvous

Space elevator

They can not do plane change at lift off since that would defeat whole purpose of launch time wiggling.

Plus, the first stage guidance in a lot of these launces is open-loop; that is, the main concern is just getting out of the thicker parts of the atmosphere in the general direction of your target, so the rocket just follows a basic pitch program to achieve just that. Once you drop to the second stage and are effectively in vacuum, then the rocket will start actively guiding on target again, having less aerodynamics and drag to deal with.

The dogleg has to wait until the craft is in the same plane as the ISS, since you can't achieve a perfect alignment anywhere but at the ascending or descending node of the 2 trajectories.

@@Jimorian That too, and that also explains why waiitng until later in the boost phase, as cross-range/plane change capability requires being off-axis to the trajectory of the rocket, and if done at lower altitudes, it would cause the rocket to spin and become destroyed.

@@eddievhfan1984 It's a very simple equation to rotate the azimuth of the trajectory at launch, even with open loop guidance. First Stages adds in some cross-range velocity second stage takes the cross-range out and doing it from lift off maximizes the time for the cross-range velocity to move the rocket. Waiting until second stage to do this would radically reduce the amount of cross-range available. Rotating the launch azimuth wont affect the pitch profile or loads, they essentially remain the same.

It’s a conical scan antenna.

@@scottmanley Thank you!

I just asked that question, I was very curious what it is.

@@scottmanley Speaking of that, haven't the russian switched to their own version of Kurs called Kurs-na a couple years ago? Current soyuz should be ukranian component free (at least the critical parts)

@@fabiosemino2214 Yes, Kurs-system is now being made by Russian company - Izhevsk Radio Plant.

please tell me this is a joke

ok that's interesting... do you know why and how they did it?

@(S)-Riley Dunn oh i assumed he meant the cm reorienting with the lm

The moon also rotates much more slowly

@@ReinoGoo and the orbits were near equatorial, so it all came down to phasing by selecting correct launch time

Antigravity I heard

Probably just prop-jumped into orbit

Abuse of the J2 terrain generation bug I think

In this case there wouldn't be any constraints by your relative inclination so you could always launch at the perfect time and do rendezvous in one orbit by inserting into a orbit with a ~400km Apogee and rendezvous the ISS when you reach Apogee. However there would be a higher relative velocity to the station during rendezvous so in a realistic scenario spacecraft would probably still use a multiorbit approach to raise the orbit in several steps.

And the view from ISS would be a narrow strip around the equator. The higher the inclination the more from the planet you can see or be seen.

For the simplists virgins, it would be a wet dream. Just point and shoot at the right time. For the Chad scientists, it would be a nightmare. First of all, you need to ensure that you have a launch base on the Equator, which I think only the French have, in French Guyana (fun fact, Soyuz also has some launches from there, but not to ISS). So, you would first need WW3 for who controls a part of Latin America or Central Africa suitable for launching this thing. And it would also make monitoring a bit more challenging. Frankly, you cannot get a 'universally' good orbit. ISS is placed with it's current inclination because 2 of the first modules (including the ver first) were built and launched by Russia, so they launched on the best orbit for them, which could also be serviced by US rockets. If it was for US, they would have rather placed it somewhere near the 20 degrees inclination range, so it would pass right over Florida, from where they are launching. China would probably place it somewherenear 45. Only EU, if we ever have the money for something like this, would ever place it on the ecuator.

Gulag engineering was good. Later they removed Gulag from their engineer education program all went downhill.

Not possible till we have Axiom Station at 27° N don't have to accommodate for Russia launch windows

@@tomcat124us Please elaborate!

@@d.jensen5153 ISS was placed in a specific orbit that caters to Russia. If and when axiom space launch a new space station will be launched from Florida. Placed in a more favorable orbit that would allow quick docking and 7 seat config. Not need to be in transit a day in a half.

@@tomcat124us Thanks :)

Some nice, bare-ass speculation on my part suggests that even if they could add the delta V to the falcon 9 and/or dragon (expendable falcon 9), they'd still have to slow back down. Not really feasible at all.

Just some extra mission planning.

Soyuz is flight proven. Dragon Crew Test were also testing manual control and a bunch of other experiments proving its capabilities. I'd expect NASA would want a track record of reliability before they begin to slowly optimize time to intercept.

I think what it needs most is a reason to do it. If the crew has the space to move around and be comfortable, it's probably not worth it to move the whole space station to get them there faster.

I remember that during demo-2 mission they actually delayed docking so that Bob & Doug could get 7 hours of good sleep before docking.

Haha
