I agree.

Also, I've sunk upwards of one thousand hours into KSP and got my money's worth back a long time ago, so I don't mind if it is overpriced.

[@radiofrog]

Anyone else think a lot of the KSP fan base is being a little ungrateful? The devs have come so far releasing *loads* of free content for a reasonably priced game, and now that there's a price tag on some content people are acting like they've been robbed at gunpoint. Maybe some of them need to take a look at what EA, Ubisoft, or other Early Access devs are doing and get a little perspective on just how good we have it.

[@danastamosiunas4177]

Hey Scott, just wanted to say that you make amazing videos and have maybe the best balance of technical detail and entertainment on youtube. Any news when the next Going nuclear part is coming out? watched all five in 2 days now, some of the best videos I've ever seen.

[@fiveoneecho]

I love the mods for historic parts, but making history is awesome because the parts will always be there, even right after an update. They will be balanced properly, and fit in with stock stuff well, so it’s just awesome to have these now!

[@attacksquirrel8643]

I'm looking forward to trying out these engines once the modding community has caught up to version 1.4.

[@Keavon]

That's pretty mind-blowing that the Titan II engine was actually modified to work with three different types of propellants. I would have thought their design requirements would be vastly different and attempting to use different fuels would be far more difficult than starting from the drawing board. Also, did I miss it, or is there no RL-10 analogue?

[@Karagianis]

Just like to mention I started a new career mode file in KSP today with the new DLC added. The Pea command pod (2 crew soviet ball pod) is broken for some contracts, used it for a tourist contract and when got them back to kerbin safely they disappeared! Concract's not complete, but they're no longer available in the VAB so I can't try sending them up again in a different pod either. :P

[@Karagianis]

Forget what I said, it's not the pea, trouism contracts are just broken. They will not complete in any type of command pod.

[@kinnetikira]

[@RichsRidesandRestorations]

The 1x J-2 was used on the S-IVB stage of the Saturn V and Saturn IB, the earlier Saturn I used the S-IV stage with a cluster of 6x RL-10 engines. The S-IVB had a thrust of 889.6kN vs 400.32kN for the S-IV.

[@spacekii]

I love this dlc, made a five meter re usable rocket similar to the BFR using the new 5m parts. So cool!

[@whatsinanameish]

I like the part at six minutes in where you see a launching rocket absolutely covered in ice at the fuel storage level. I wonder if they anticipate such weight in their calculations. It would seem to be a tricky guess as you can't predict how much will fall off and how much will cling on tenaciously.

[@marekklucka4407]

Hi Scott. I've been thinking. Do you think you could make an explanatory about how is the lift from the engine transferred to the whole rocket? It comes from the combustion chamber or from the cone? Also how is the engine actually attached to the rocket? Because there must be a lot of stress and different forces going on, and looking only on the schematics I've not been able to find anything that would explain it to me. I get the basic idea behind rocket engines, but this is above my head

[@CommandLineVulpine]

Unrelated, I see yo u have anti-aliasing off in KSP. Does KSP get a particularly good performance boost for doing so?

[@User-wp1yb]

[@DC2022]

NERV. No classic engine can beat this boy only ion engines and only for light probe because its punny thrust.

[@44R0Ndin]

The best of the new engines for interplanetary travel would be the AJ-10, great thrust and specific impulse for not much weight. That being said, with patience, an ion engine is all you need to move even 10 tons to any orbit in the stock solar system, from any orbit in the stock solar system. As a matter of fact, the best solution to propulsion that will work anywhere in the stock solar system is some ion engines, xenon tanks, fuel/oxidizer tanks, and enough fuel cell arrays to power the ion engines, with about 1-10k electric charge in batteries to act as a power buffer. Doesn't take much fuel to generate a whole lot of electric power for the ion engines, so it is quite efficient for even large missions. The only problem is the high part count this approach can require due to the number of engines and fuel cell arrays you need to get enough thrust.

I do hope that KSP starts to get more support with this DLC, it has been slow going for a while. I would like for this to be like the atlas rising of KSP, starting a new era of DLC.

[@gelatinous6915]

I wish they had added an H1 engine due to the sheer number of rockets that used them, but I definitely understand why they didn't. The very hi-thrust + lo-efficiency combination would make it useless in KSP outside of historical recreations.

[@azmanabdula]

I have been into science my whole life, and it still baffles me how we managed to make thrusters capable of putting us into orbit, its amazing how someone sat down and said, it can be done........ What can be done? Riding explosions into orbit ..... okay?!?

[@starvingfilmcritic]

I believe you mean that the third stage of the Saturn V was almost identical to the second stage of the Saturn IB. The Saturn I upper stage (The S-IV) was powered by 6 RL-10 engines and used in early flights because development of the J-2 engine needed more time before the S-IVB could fly in the mid 1960s. The Saturn V variant of the S-IVB was also restartable, whereas the Saturn IB version was not.

[@scottmanley]

That’s what I meant indeed. Thanks!

[@reidhulshof3645]

I can’t be the only one bothered by how over powered the wolfhound engine is. Whenever I try to replicate Apollo missions I always have to put a bunch of dead weight in the service module to avoid it having 2000+ m/s of delta v and lower the thrust so it isn’t pulling 4 G’s during maneuvers

[@SkyrimHod]

I just wish they had modified the tech tree to be more historically accurate as well. Guess I'll need to wait for a few more mods to be updated for that though.

[@NoahThomas29]

I would like some more planets added.

[@Pandonaut]

[@maxhammerum7705]

Bit disappointed by a bunch of missing "links" to build some of the rockets. The first thing i did with this dlc this morning was to build an saturn 5 in lunar configuration and there is no way to have the small jr docking port sit ontop of the mk2-3 command pod without having to remove tha launch escape system. Its just annoying since i love the stockalike nature of these parts but you just cant create something that looks nice with them because of all these small missing links :(

[@44R0Ndin]

You mean you can't have the escape system connected to the jr docking port, and then use an action group set to both the escape system fire, and the jr docking port "decouple" commands, that way it jettisons correctly? By the way, that's exactly what I do, I just use the full-size port instead of the Jr one because how are you supposed to fit a Kerbal thru the tiny port anyways.

[@skavies2351]

So where does all that force from the engines push back at? We have a rocket that generates 8 million newtons of force, but where in the engine is that upward force pushing the rocket up? If we put that rocket straight on the ground, the bell housing will crush, so it's not that. The mounting brackets for the engines generally look inadequate to hold the rocket up, much less accelerate it at 3g or whatever. I get the basic idea of a controlled explosion pushing down, but what part of the rocket takes that reaction force and pushes back up? The little plate in the combustion chamber that's often filled with small holes?

[@scottmanley]

The engine bell can quite happily handle the force, but yes, if you try to sit a rocket on its engines on the ground they'll collapse because the force is distributed differentely.

[@TheRaphasan]

Actually, there is no need to be a part where the force "pushes back", otherwise no rocket would work in space. A rocket works because linear momentum needs to be conserved, so as the exhaust gases are expelled from the nozzle at very high speeds, the rocket moves on the opposite direction to conserve momentum.

[@skavies2351]

yes, but that opposite force is pushing on the rocket somewhere. Sire some of it is in the bell changing an outward force to a downward force, but that's only a small fraction of the total force. if all of the force is being pushed through the engine (which makes sense as opposed to a high pressure area pushing up on the bottom of the rocket which would work at very slow speeds) what part of the engine is taking all that force, and how is it transferring all that force to the rocket when all the mounting brackets look like thin rods that often aren't even in line with the expected forces?

[@NoNameAtAll2]

Raphael Maia The propelling alone will give really low Isp, the engine bell is used to capture force of expansion created by overheated fuel

[@NoNameAtAll2]

Michael Grondahl If we put rocket on the ground on engine bells, all weight would be on the very edge of bells If you put engines onto sand hills that fill bells from inside, the rocket will stand

[@snack881]

[@karlstorie8813]

I'm pretty sure the Titan II engine wasn't the longest-running U.S. engine. The just launched a "Delta II" last year, and I think they've got a couple of them left. They're really Thrust-Augmented Thor-Deltas (where did this insane habit of naming a combination by its uppermost, smallest stage come from?) and the Thor first flew in January 1958. But then, as you point out, the upper stage of the Vanguard first flew (successfully) on St. Patrick's Day, 1958, and that's the same engine as the Delta stage (and the Apollo SPS, Shuttle OMS, etc.) So the Thor engine has it beat by a couple of months....

[@scottmanley]

I said 'Booster engine'. The Thor/Delta rockets used to use the MB-3 engine, the Delta II uses the RS-27 which was first seen on a Delta rocket in 1974.

[@karlstorie8813]

Ah...thanks for the correction. I just assumed a Thor was a Thor. (I don't know why--an Atlas isn't an Atlas for sure!) You learn something new every day.

[@spencerolson416]

Elon musk said the BFR would look small in comparison to future rockets. What is the theoretical/reasonable limit to rockets with today’s or near future rocket tech (material/fuel/engine). P.S. I have heard of the sea dragon how much bigger can we go 56 years later?

[@danielkorladis7869]

Cost.

[@Eagles_Eye]

Well eventually you would need so much thrust it would become inefficient to go bigger, im not sure how big that is, I imagen by then they will sent multiple rockets into orbit. Combine parts and go from there. Instead of launching 1 huge rocket from earth surface
