Hey all! Decided to try out another mission recreation, this time from For All Mankind, hope you enjoy! A big thank you to Star Trek Timelines for sponsoring this video, Click on the link and download the official Star Trek Game: sttlink.onelink.me/Z8Hp/ytsf Factual mistake at the end: Sea Dragons 1st stage can gimbal, its the second stage that can't. The TVC engines do remain on from liftoff to orbit though.
They use the jet engines on Pathfinder to fly ahead of the carrier plane and maintain flight without having to glide. Also used to help with fuel ullage. And I think the wings aren’t thick enough.
the Pathfinder from the show had two turbo ramjets that were ignited on separation from the C-5 carrier plane, it would propel them up to a high altitude, then ignite the NERVA engine
Ah I see, that actually makes sense. Didn't see it on the show, but explains how it's able to takeoff. (though I didn't have enough mass ratio left for the weight of jets in this build)
I agree, it sounds reasonable they start with SABRE engine, then use nuclear engine for rest the way up. They probably had this in mind, but cut it out to make sure the scene is smooth and concise.
Awesome video! Congrats on those long deserved 10k subs! I’m liking this new “style” of video, not being terminal velocity over and over again, that’s still fun to watch but I like this more. I had a lot of fun watching this! Thank you!
Glad you enjoyed it! Aye - this content definitely seems more broadly appealing as well. I still like Terminal Velocity, but I'll be looking to wrap up the series within a few months.
Amazing editing, -wonderful- EPIC video! My only niggle is that the C-5 is going to have a few yaw control issues with a burnt-off rudder! Edit: Just got to the end where you explain it all. Fair enough reasoning!
Well done TD. Love FaM, and you recreating missions from the show will have me hyped for a good long time 😎 Any news on the return of Terminal Velocity?
Thanks! Heh, we'll see how this video does, might do more. Terminal Velocity will still continue - I'm hoping to get at least 1 episode done per month at minimum, however I am hoping to wrap the series up overall by end of year.
This was really cool, especially the Show vs Reality section. I knew Pathfinder had impulse density problems, but not to what extent. Also random question, what was the Pathfinder separation velocity? I read a NASA doc that suggested 3km/s for optimal sizing
I think that Pathfinder might have used atmosphere instead of onboard fuel for the first phase of its nuclear flight, thus largely reducing the amount of fuel required to reach orbit
While I don't like FAM due to me being a space nerd seeking realism a lot more than drama, I absolutely appreciate your work you've put into this video. While it's cool to fly those entire huge and heavy shuttles to the Moon, it's terribly inefficient in terms of mass. Still wondering how the hell am I supposed to believe Buran somehow got to the Moon while looking basically the same as its real life counterpart. I get it, it's just a show that needs the cool factor more than realism, because that's what get them some views.
Mars-94 is an odd duck. SSTOing from Earth to Mars is... quite something. Might take a stab at the Season 3 vehicles some day though. I like Pathfinder the most though.
@@TDChannelKSP Mars 94 doesn’t even show any landers or hab modules, that one is difficult because you don’t know the mission profile (but I would say it’s easier because that means you can make your own mission plan, for example you could say Mars 94 landed on pluto before returning to earth **wink wink** because we don’t know the details). And the SSTO part is difficult too because you have to have enough thrust to lift off of earth with NTR.
@@TDChannelKSP If I'm not mistaken, FAM's NASA's Mars mission starts from the Moon not Earth, though that's quite a trip anyway and that bigger-sized shuttle seems very tricky to recreate. Helios built their gigantic ship in orbit, we don't know all the stuff on it either and it must leave a lot of freedom to recreate it too. The soviet one is the one we know the least about, so it would leave the most artistic freedom, though it should take off from Earth's surface with NTRs...
There’s the fact that the C-5 can’t go supersonic. Even with it being at a moderate altitude the TWR and the velocity for orbit with the nukes can’t cut it as it is way too slow for an orbital craft. Plus with this vehicle apparently building their lunar gateway is just a dumb idea. They should have went for the original shuttle idea imho.

Fantastic work! Something JUST occurred to me...wouldn't the ignition of the NERVA engines of the nuclear shuttle irradiate the crew of the carrier aircraft, the crew of the lower stage of a TSTO launch vehicle, etc.? I don't think the creators of "For All Mankind" took that into account... (Of course, I've ALWAYS thought that carrying the extra weight of wings on ANY spacecraft operating beyond LEO is just dumb - just IMHO).
Thanks! Yeah, that would be an issue. Some people have pointed out the SABRE-looking engines could be airbreathing engines meant to boost the vehicle away from the C-5 and accelerate before NERVA ignition. In the show it just sorta floated off the C-5 nicely to gain distance away from the carrier before engine ignition.
you MUST recreate Sojourner 1. Anyway isn’t pathfinder a bit dangerous? Flying over US soil with a nuclear device onboard ready to explode? Very very good recreation.
@@TDChannelKSP wow. So either the pathfinders engines or the sea dragons engines were throttleable or you somehow managed to get the same twr for both, right?

SO that is how they did it. how they used shuttle/shuttle 2 to get to the moon. ever thought about using a SLS Core size ET? to put shuttle block one into Trans-Lunar? and Skylab was in a 51.1 degree orbit NOT a 28.5. does this mission profile use the same type of lunar orbit as the Gateway is going to have?
I don't believe the larger SLS 1B tank would be enough to send the shuttle on trans-lunar trajectory by itself - a 30% fuel increase is sadly not a 30% delta-v increase. Normal shuttle in particular is pretty heavy (around 80 tons dry) While true that OTL Skylab was in a different inclination, it was mentioned in FAM using Skylab as a refueling stop for shuttle 1.0 (shuttle 2.0 just magically flies direct to the moon), perhaps with this purpose in mind Skylab was placed at lunar inclination. FAM didn't provide much detail on the lunar orbit, so I settled with an equatorial low circular orbit, since the encounter between Buran and Pathfinder seem to happen close to the Moon. With refueling, Pathfinder can easily do any orbit, or even land.
What even are the "SNTPPFE100 Nuclear Engines"? I searched for them and unlike the other engines I couldn't find anything about them. I know they run on LH2, but can you give more info?
Thanks! Also I asked 1 more question in the Project Tholia video but you never got the message even after I reposted it yesterday. It's in the replies in the comment I made. I also asked a question in the Apollo Infinity video which you never answered. Well, I hope you get this message!
Correct! I mention that at the end. There's a few problems: 1: Pathfinder is *heavy* and doesn't fly that well. Even in real life, an empty shuttle needs to pitch up quite a bit from a 747 in a dive to gain separation. There's no way for it to gracefully float upwards like in the show, you need a fast dive with a rather dramatic pull up. 2: This introduces issues - you're in a dive now, deeper into the atmosphere, and you need to halt that descent and pitch up to vertical. This takes a pretty good chunk of fuel to do - much more than I have. Pathfinder as an SSTO already has razor thin payload margins as is. 3: It also introduces ullage issues, with drag causing all the fuel to go forward, so igniting the NTRs is tricky. By doing a steep climb, you retain vertical velocity, making it a much more efficient ascent.
I wonder, could Pathfinder work at least to LEO with the available propellant volume in the wings if instead of hydrogen, it used a different, denser propellant (e.g. methane) for the NTR? Methane drops the specific impulse by a third or so, but it is about 6 times as dense as hydrogen, so you get about four times as much impulse per volume.
Hmm, I'd have to work it out but I'm not sure. The density would certainly help, but Pathfinder effectively needs SSTO-levels of delta-v, around 8.8 km/s or so. Would probably need a new carrier aircraft - LH2 Pathfinder already pushes the limits of a C5, CH4 Pathfinder would need one of those crazy-looking double fuselage AN-225s or something.
@@TDChannelKSP If the show configuration would fit 60 tons of LH2, it would fit 360 tons of LCH4, which with 50 tons empty mass pushes ln(m1/m0) (with no payload) from 0.79 to 2.1, and thus the needed v_e for 8.8 km/s ∆v down from 11.2 km/s, which is out of reach of any solid-core NTR, to just 4.2 km/s, which would absolutely be in reach of a solid-core methane (or even methanol, if coking from methane propellant is a serious concern) NTR. Of course, as you said, quadrupling the launch mass does pose an issue regarding both the carrier aircraft, and also requiring quite a bit more reactor power to maintain the same liftoff TWR. Using NASA's CEA tool to calculate the performance of a CH4 NTR with 100 atm chamber pressure, 3000 K core temp and a nozzle area ratio of 100, I get 5.6 km/s vacuum exhaust velocity, which would achieve 8.8 km/s delta-V at a quite reasonable mass ratio of 4.8, meaning the 50 ton empty mass/360 ton fuel Pathfinder would be able to carry ~40 tons of payload into LEO.
There's a lot of mods used in this build, but most can be found in the RP-1 express installation: github.com/KSP-RO/RP-0/wiki/RO-&-RP-1-Express-Installation-for-1.12.3 The internal tank configs were the same custom ones I used for my Skylon video, and aren't a part of normal RO though.
Yes, Sea Dragon got destroyed. The scene relates to Season 2 EP10 of "For All Mankind" - I can explain, if you're not concerned about plot spoilers of that show.
Hi. Using google translate to read this message since I don't speak Russian... The events are based on the alt-history TV show "For All Mankind". Here's the context: - Spoiler alert! - In the show, the USSR uses a weaponized version of Buran to "blockade" the Moon, to stop Sea Dragon from delivering its nuclear payload to the lunar surface. If Buran destroys Sea Dragon, or Pathfinder destroys Buran, WW3 starts. So, the commander of Pathfinder decides to shoot down Sea Dragon, ending the standoff. Its destruction is blamed on mechanical failure, and USA-USSR tensions lower after that.

Я не понял прикол с бураном. И зачем вообще нужен был sea dragon если его уничтожили? Бригаду
Hi. Using google translate to read this message since I don't speak Russian...
The events are based on the alt-history TV show "For All Mankind". Here's the context:
- Spoiler alert! -
In the show, the USSR uses a weaponized version of Buran to "blockade" the Moon, to stop Sea Dragon from delivering its nuclear payload to the lunar surface.
If Buran destroys Sea Dragon, or Pathfinder destroys Buran, WW3 starts. So, the commander of Pathfinder decides to shoot down Sea Dragon, ending the standoff. Its destruction is blamed on mechanical failure, and USA-USSR tensions lower after that.
