The rotational thrust vectoring at 8:50 is so awesome! :D Reminds me of a dance line.

Just to put it out there for anyone still watching this :P.. Procedural parts SRBs do now have a setting to adjust the nozzle's tilt. So you can actually build an SRB, and mess with the tilt of the nozzle to counteract it's offset thrust.

I looked to see if there is an Atlas 404. Couldn't find it...

Hi Scott, I've added nozzle deflection on ProceduralSRBs! The plugin should be updated soon. I was actually adding another feature in the ProceduralPart plugin while listening to your video. I've added polyhedral (3 to 12 sides), mk2 & mk3 shapes and I've also managed to code an adapter part that support different shapes and sizes (like hexagon to mk2 for example). Theses ares mostly finished and should come soon.

Crazy to live in a time where the mission this video discusses, Osiris REX, had already been completed.

Excellent video Scott! I'm always impressed by your ability to disseminate technical info.

Huh. Well the asymmetry makes sense now. I guess it's easier to just use thrust vectoring than it is to redesign the whole rocket.

This reminds me of the shuttle engines looking like they're locked offset to the boosters on launch giving a bit of a side ways drag.

I just started playing KSP and I absolutely love how you use KSP to show how thing work. we'll done, sub'd for sure

Love these Real situations in KSP videos! Great work Scott, keep it up! :)

Your voice is so soothing to listen to, couple that with the technical amazingness of KSP and its probably my favourite thing ever.

Excellent and informative video. I love when you make videos like this.

I was at the ULA Ground Station in Denver for a launch viewing of OSIRIS-rEX. I asked them this very same question about the 441 configuration! It was very interesting to get to talk to the engineers about this.

I have been looking for an answer to this question forever - thank you!

Use the SSTU mod, it has what you are looking for in it's SRBs. I guess now we know why ULA launches are so expensive.

thank you for posting this video I was thinking about that all during the launch

Thank you for the explanation Scott! I'm not a total rocket noob, but have been wondering about the strange Atlas V SRB configurations for some time and seeing OSIRIS-REX being launched on a 411 just brought the question up again. :)

Well, I'm not Scott, but I can suggest a couple things. 1) Keep them as small as possible. See how tiny you can make the probe and still be able to cram all the necessary bits on in a plausible manner. 2) Look at real probes for inspiration. A personal favorite of mine is Luna 9. There's something amusing about a weird lumpy probe that shoots a big egg into the sky. 3) Try AIES and DMagic Orbital science; they both add nice probe bits and science experiments respectively.

Great video! I would lead off why the SRB's are offset at the beginning of the video instead of the end. Pose the challenge at the beginning so we can all be stupified until we get shown this awesome workaround and how it works. Love these explanation vids. Short and sweet.

I always contemplated the "why" of the Atlas V's booster symmetry problem. had no idea the answer was so simple!

"Power sliding off the launch pad like a boss" lmao. nice one Scott. Great video otherwise too! The way I tried this before watching your video was just to reduce the SRB throttle to 50% & the regular engines do just fine too - the SRB almost lasted as long as the 1st stage too :)

Really interesting video. Cheers :D.

And now, the Osiris-Rex is safely on its way to Bennu after a flawless launch.

Interesting, I might look into this for my career mode saves.

Thanks Scott, that was very interesting. I would like to know more about the Atlas and plumbing on the booster-stage.

Scott! love your videos!! I wondered if you offered an introduction to making space stations, I use the console version

Thanks Scott, Nasa TV mentioned 411 configuration twice already since I started watching the launch coverage - kinda nice to know what they mean. Now if only they would put up altitude in meters and not feet - fingers crossed :)

as long as the taxpayers are funding it in dollars, you will see feet and miles on NASA.

The one tilted SRB is already found on the KSP stock "Orbiter One".

It also makes more sence from a manufacturing perspective all these configurations can be mounted to the same 5 mounting points. If you would try to space them out evenly only the 2 and 4 config could use more than one common mounting point.

So, NASA rocket engineers finally went kerbal. ... yeah.

@sharkcraft8568

Atlas V is not NASA's rocket. It was made by Untited Launch Alliance (ULA). Just saying.

There are two mods that will get you something much closer to what the Atlas 411 really looks like. KW Rocketry has an SRB that looks just like the ones used on the Atlas. Its nozzle is angled outward but I'm not sure if it's enough. Ven's Stock Revamp adds an engine that looks a lot like the RD-180. It has two nozzles and a 4 degree vector range.

I saw the Atlas V 551 in person. My oh my. Space X is really cool, but ULA is also pretty neat.

Needs Eurobeat Music! awesome as always

Scott you should come visit the Cape sometime, I got the watch the launch from the turn basin I front of THE VAB with my telescope, and it was great.

sure enough, procedural SRBs now have nozzle deflection.

Wait, we are getting asteroid samples?!?! Nice!

It's cool watching this 3 years later when they are currently mapping out where OSIRIS-REx will be making its touchdown on Bennu. Turns out Bennu is basically a giant pile of rubble so it's gonna be tricky

The back and forth movement is called porpoising. The up and down thrust of the mammals tail cause it’s nose to go up and down in the water.

Scott, what computer system do you use? Specs, please... Thanks!

5:44 oh no oh no it's gonna crash oh my GOD

I think it would also have been useful to mention that the X2X and X4X versions are asymmetrical because they use positions from the X5X setup, as all setups do. This means they don't need different mounting points depending on the version, it just means they need some and don't need others.

another thing you could do is turn down the thrust limiter on the solid rocket so it pushes less and the engine can compensate and it burns longer like you said

Hi Scott! I think that you should have rotated the two vector engines and not the solid booster to compensate the slide . The problem is that the vector engines ignite at 0 vectoring and that gives a little side push from the solid booster. If you rotate the vector engines that would compensate the side push from the booster right at the ignition. Regards!

The SRBs in reality also have an inward thrust vector built into them, so that helps as well. It was weird looking to watch! But of course the space shuttle was asymmetrical too.

Thanks for the informative video. However, I think I read there are other versions in the planning with the DEC (dual engine) version of the Centaur upper stage. For the SNC DreamChaser spaceplane I guess, or Boeing CST-100. That would add more possible versions, the bigger possibly being 552 ! But again, what number would account for the fairing, or lack thereof, when launching a Dreamchaser ?!

Scott is genius

Hunting worse than the LEM ascent stage. Gotta love it! Now, I wonder if there's a mod for offset SRB nozzles?

The drag would be crazy going sideways like that

Hi Scott. I really want to hear about your opinion about the EmDrive and the recent passing of peer review of NASA's version of the engine. Do you have any plans on making a video covering this subject in the foreseeable future?

Today's APOD shows the OSIRIS REX liftoff. I noticed the exhaust trails was slanted. Was that because the Atlas is moving laterally or because of the vectored thrust (both?)

I'm wondering what would happen if you had different style of nose cones? One can assume that it may drift, but I was wondering when and how fast would it have to go and how high would it have to be to do that.

Interesting I didn't know that

are those ISSAC modules in your capsule tab? 4:30

Your 541 was actually a 551... You can't fool us Mr. Manley!

I actually got to see Osirus Rex while it was being built at Lockheed Martin.. Got to wear the fancy white suit and everything.

hey scott can you give me a link to your orbital mechanics vid? my science teacher wants to use your vids in her class.

In real life the variants of the atlas V has it's boosters offset because the weight on the inside of the main section is not centered as well as the external engineering. Those fuel tanks aren't just neutrally weighted cans of fuel, they have a lot of internal works as well to handle that fuel and keep it safe when it's flowing.

In the 5 meter version, the centaur upper stage is inside the fairing of the rocket,not exposed.

How did you change the point of rotation on the booster in the VAB? Is that a new thing?
