- Nothing fancy, just a test launch with my space launch system mod for realism overhaul in KSP.
Sorry to disappoint those who want to see something grand and epic D:

Well, I _was_ expecting another amazing decoupling tower of Babel, but this is pretty noice, too. Reminiscent of the old Saturn V launches.
It IS grand and epic! You achieved orbit in a single stage!
finaly, after well years i think you made a vid...
Sound effects are pretty good
I love SLS and SLS related videos :) Your ascent trajectory is so shallow imo. You had to fight gravity for a good portion of your flight. Wouldn't a steeper trajectory be more optimal?
Emre Çağatay Köse
The nature of the relationship between potential and kinetic energy means that it's more efficient to gain as much velocity as possible before you climb up the gravity well.
Burning with a high angle of attack doesn't look particularly elegant, but it's the most efficient assent profile. The high angle of attack is a consequence of the low TWR of the SLS core.
If I flatten out at 130 km instead the ascent will take about 100-150 m/s more. That's not a huge amount, but in this case I was hauling a 43 tonne payload to TLI, and it's nice to have as much margin as possible.
If I linger too low too long shock heating becomes a problem. 90 km works out pretty nicely :)
make more! we love you!
Wait? You didn't land on the sun?
You're back!!!
That rocket is so cool. I think if I have realism overhaul installed in the second copy of KSP RSS( third copy of KSP), I bet I can put 200 ton payload with more kerosene boosters mounted on 10 meter cryogenic core stage with optional upper stage(2nd stage, kerosene boosters count as stage 0). But i have to launch it quickly so to minimize boil off. I have to keep stock feel on KSP RSS so I recommend making a third copy and then simply add realism overhaul to a third copy while retaining RSS.
Beautiful.
The cosine losses are strong with this one.
+Matthew Ferrie
More powerful boosters are required for a more efficient ascent :)
***** So what kind of math is required to design the ideal rocket? I'm planning to come up with a standard launcher family for the light, medium, heavy, super-heavy, and ludicrous classifications.
You forgot a launch escape tower, because nobody wants the Kerbals to die when something goes wrong.
Just wanna ask are you proud of your because i would be! I am just starting to develop games on my own and this is a fantastic piece of work mind you!
Dumb question but do we know if the EUS will have any sort of ullage motors? It seems a bit odd for it to use soviet style staging and just fire straight out of the interstage
Pleaaaaaaase, do more videos, is so fucking awesome! *_*
That shroud was a bit large for such a slim payload. lol
What SLS block are you depicting? Block 1 is only ever shown using orion, so I'm not sure what it looks like with another payload. The final stage looked to wide to be block 1, but NASA haven't exactly finalised that stage anyway...
HALL9000ish
Block 1B with the Ares1 boosters and the EUS and a 10 meter fairing. The performance of Block 1A is hampered by the undersized delta IV upper stage. With the way the winds are currently blowing that upper stage will only be used on the first and possibly second flight, so I'm probably not even going to bother with it.
+okankyoto
It's definitely nice to see NASA pushing for a quick transition to the EUS. Block 1A is such an awkward configuration. I just hope the stars align and they actually get started on developing payloads in time.
I visit NSF quote often, so I think I'm familiar with your work. I'm assuming you made the orange SLS renders that I saw at NSF? Very nicely done!
Do you by any chance know if there are more finalized numbers availible on the dry/wet masses for the SLS now that it has passed CDR? I'm asking because I've been able to push quite a bit more payload to BLEO destinations than the advertised capability of this configuration, and I'm wondering if I'm made some mistake somewhere.

I just took a second look at these numbers, and the payload capacities only appear to make sense if you assume the initial mass in LEO is 93 tonnes for payload and propellant + the empty mass of the EUS.
But isn't that just the payload that what the core can push to LEO with no upper stage?
With a fully fueled EUS and a large payload core burnout happens earlier, and the staging becomes much more efficient due to the high mass of the core. With a 40 tonne payload on top of the EUS I can easily push 130 tonnes of starting mass to LEO, and with that I can push those 40 tonnes all the way to trans-Mars injection.
This is great. How many tons was your payload to that orbit (Looked like 253km x 206)?
+Ryan Sommers
This payload was something like 43 tonnes, with enough fuel remaining on the EUS to throw it to TLI.
The total mass that this configuration can throw to LEO is something like 130 tonnes.
No Jupiter landing-takeoff? :(
PLEASE TELL ME what is that texture pack called ? How Can I find it I want the Graphics exactly like you !!
Does anyone know when the SLS block 2 will actually launch? In relation to the block 1 launch planned for 2017, is there currently a plan or scope? NASA's been doing a lot of, "We'll do "X" in some unspecified amount of time," recently.
I'm predicting they never develop the rocket that far. It will get as far as Block 1B so they can fly Orion to the Moon and justify the program, but it makes no sense to pursue SLS if SpaceX's BFR is successful.
How i can instalation RSS mod and 2048 textures? I can't see this mod in KSP
How heavy is the payload? When I get out a 100 ton dummy payload, its almost impossible to get into orbit because of the low twr.
The Block IB will be able to lift 105 tons - but remember, that figure includes the extra fuel in the upper stage for Earth departure, not just payload.
What sound mod did you use?
What is your version ksp? What mods do you have?
Hey Maccollo, what is the mod on the right of KER window?
+giuliano tulerman
It's Planet Shine; a mod that puts a light source on the lit side of the planet. For example, when you are in low orbit above Duna (or Mars in RSS) the planet will appear to reflect red light onto the underside of the spacecraft.
Cool, Thanks Maccollo. I love your replicas and missions. Talking about missions, can you make a Shuttle Flight or Falcon 9 Landing on a Pad or on Barge, plz
Your mod is compatible with tweakscale?
What is the texture's name?
Are the launches really supposed to be angled that high up at around 90km? If so, I've been doing my launches wrong. (I also play ro)
+Sammy Feldman I think he has a mod which makes kerbin the same as earth, and he is going for a high orbit.
Harry Jamieson I know, I have the same mods. Just when I'm at 90km, I don't have a 40 degree alpha! lol.
Sammy Feldman
The high angle of attack is simply because of the terrible TWR of the SLS. This thing really struggles to get to orbit.
I found this ascent to be the most efficient through trial and error. Going steeper and flattening out higher cost me about 100-150 m/s more deltaV.... But I could be wrong. There's a link to the mod in the description. If you feel like it you could try to do a more efficient launch, see how much you can throw to the moon or something. If you can come up with a more efficient ascent I wouldn't mind learning of it :)
1:30 What mod allows you to use that engine?
+Dawizard919
That's the placeholder RS25 the mod I linked in the description.
can you maybe do a tutorial on how to build this? i have the parts but i dont know how to assemble this xD
In your visiting every planet video you missed Jool
Sylas Martin hi man nice video? but what mods are you using i am really interested
Agree
That's Jorn
There's a quite a few, but the important ones are:
Realism overhaul and all the essential mods
Realism visual enhancement
Active texture management
Kerbal joint reinforcement
Planet shine
And my SLS mod
Look, I don't know if I'm missing something, but wasn't there an idea to use an SRB as the launch stage to bring a crew capsule to orbit? It was cancelled, I believe, because it was deemed too dangerous in an abort scenario. The space shuttle was retired because it was an aging system, and also because the SRBs were considered unsafe. So the solution for being crew to orbit in the future is to build a gigantic rocket... With more SRBs. Is there something I'm not getting? I know they're cheap power, but it just feels like back and forth to me.
Bringing*
SRB's are cheap and powerful, but they are too dangerous for humans in the event of failure, like if all engines failed on a shuttle launch, they'd have to wait for the SRB's to burn out, and probably, by that point, it'll be too far for Kennedy to do a Return To Launch Site Abort. And the rocket you are thinking of is the Ares I. It was deemed unsafe for human use, but I'd like to see a cargo version of it one day. There's also another rocket built by Ariane Space called the Vega, which uses an Solid Fuel for it's first stage to carry light payloads into orbit.
Matthew Penguin
Thanks for the name of the rocket, but that still doesn't answer the question. What makes the SLS able to use them for crewed launches? Especially when every other crew rated vehicle either is initially deemed unsafe, or at least one of the causes of retirement of said vessel i.e. the Space Shuttle.
retirement usually comes about due to new engines becoming more efficient, and being cheaper to replace it than to continue launching it. SRB's are not very common in manned launchers due to their uncontrollability, and high acceleration, but the US and India have developed lower thrust SRB's to use, but a Solid powered first stage would result in a 100% chance of crew death. Every other crew vehicle is initially deemed unsafe, there are not very many crew rated vehicles that are actually designed initially for crew, like the soyuz. and crew vehicles that are being developed today are built for the purpose of transporting crew, but they dont start off launching crew right away. the SLS is planned to make it's first launch in 2017, but it's first crew launch is planned for later than 2020, likely 2025
Yeah, that was the Ares I rocket for Project Constellation. Supposedly it had a 100 percent chance of killing the crew if it exploded below a certain speed, because the capsule wouldn't have cleared the explosion even if the LES fired successfully. SLS presumably has enough thrust on liftoff that that's no longer a problem.
REVIVAL!!!!!!!!!
The KSP forum link doesn't work.
Hey guys
well..actually it's not an sls rocket, it's an ares V rocket, but good job man!
No no, It's an SLS =)
MORE VIDIOS
Only for Realism Overhaul? ;~;
I was expecting something grand and epic... :(
btw, after the booster seperation my engines are not powerfull enough.. i use the same as you
+KleytenHD
The core should have a TWR between 0.9 and 1 at booster separation. This is enough, although it should really have more as it isn't enough to get the to orbit efficiently. The boosters burn out to quickly and the core doesn't have enough TWR to compensate. As a result it takes 10 km/s to reach orbit.

Which mods did you use? not talking about the SLS but the one that told you how high your AP or PE was

Kerbal Engineer Redux
Thanks!
It looks like Ares V
It's basically the same rocket, but with a different upper stage.
Buran
my fuel is burning up way faster in my boosters..
+KleytenHD
This most likely means the thrust curve isn't functioning properly. I will have to take a look at it... again :/
can you maybe do a video on the build?
Download link !!!!!!
Its in the description
RVE looks like shit from the launchpad and OK from the low orbit...

make a crash with colombia
Wait, where is the rest of the kerbal civilisation?
Are kerbans even real?
Is it all just a child's dream?
Is the universe just a child's dream?
Meh, Imma go eat a donut while guys figure it out
Bye
make more! we love you!
