KSP 2: Building and flying a Laythe SSTO!
HTML-код
- Опубликовано: 13 июл 2024
- It is another exciting day my dudes, for we at long last manage to create a Laythe-capable SSTO! There were lots of twists and turns along the way, including (as always) many a Kraken attack. But perhaps the Kraken attacks were justified, after all, the entire mission hinged upon a very dubious allegience I formed with the beast.

I'm impressed with your dedication to KSP2, I'm definitely waiting a year or two to purchase. Good video!
For real. I lost patience after a few hours of lagging and glitches. Props to him for churning out KSP2 content. Hopefully devs can get updates going soon.
He should use it in his Life on Lyathe show!!
I’d rather get the first for cheaper
Buy it while its in early access or its gonna be more expensive later
@@floppi7098 yeah if anyone is planning on buying it when it is officially released they might as well buy it now and treat it as a pre order for a discount
Matt, your dedication to getting this game to "work" is very commendable. I wouldnt be able to do it.
Making his income probably helps with motivation.
Must be a nightmare.
@@onix3539 yea to a certain point sure but he could definitely go back to KSP1 and do some shit there if he wanted to. Like im not even playing and it bothers me
ksp 2 makes me appreciate ksp 1 so much more now, there are so many things I just took for granted
autostrut my beloved
Like it being playable
@@MattLowne also uncooked spaghetti as opposed cooked spaghetti
@@shooter2224 Define "playable." Josh from Let's Game It Out manages to play games in seconds per frame territory. Maybe we should use the law field's "Reasonable Person" standard? lol
@@ledumpsterfire6474 If you think that's playable you don't know what playable means.
Nice to see you making use of a Kraken drive again
honestly it's like a KSP equivalent of the Astrophage drive from Project Hail Mary - an unstable, incredibly powerful but poorly understood method of propulsion
@@crispybottom the difference between an astrohage drive and a kraken drive is one cooks you behind it
@@crispybottom I finished the book some weeks ago, and I loved it!
indeed
Nice👌👌
im continually shocked with the things they made worse or left out from KSP1. Thanks for being a voice/advocate for essentials like trajectory lines!
This is a bug, they’re supposed to be there. The game as it is now is nowhere near where they want it to be, that’s why they released in early acces. Let’s just hope the patches fix a lot of the bugs and incomplete features when they start being released in a few weeks
@@thespacepeacock Release in early access for full prize and a bug they've been trying to beat for years. Yeah brah.
@@Klajnepojken yeah, the price is too high for early acces. That being said, if you don’t want to pay that much for the game in its current state simply dont buy it and wait until more features get added and bugs get fixed
@@thespacepeacock Exactly. You either pay 50 now or 50 after but you still get all the features. Tbh it's nice they did an early access release to drive the development by community feedback and not just to cover up the bugs. They definitely have functioning QA department and in the game's current state there is no chance they would've made a full release and not expect a huge backlash.
What's funny is people paying the full price and not even caring to look what's in the early access game. One of the first things you see on the store is their roadmap and people giving bad reviews because there is no science or multiplayer is just wrong. At least these reviews get reset when it fully comes out.
@@Draxi_1 They devs don't ever actually listen to the community dude.... And why would they? They already know everything about the game and what they want for the game.
You have a lot more patience with this game than I do! Kudos
i hope that you will make other good videos 📹 .i really like your work, and you can see 👀 other planet's and share it with us
Good 👍 job
It being his job probably helps
@@OutsiderLabs true, but you couldn't pay me to play ksp 2 in its current state. Lol
Well you know what they say Matt.
"A good landing is any one you can walk away from. A great landing is one where they can reuse the plane." - First Officer Douglas Richardson, Cabin Pressure
Doing some quick math. During the segment of the trans-Jool injection lasting from the first frame of 6:53 to the first frame of 6:59, the craft's speed increased by 1764 m/s while the listed Dv dropped by 17 m/s. This means that each m/s of listed Dv is worth about 103.8 m/s of real Dv, and so at the time the vessel left Kerbin's atmosphere, it's true Dv was 1445x103.8 = almost exactly 150 km/s. Side-note, during the aforementioned burn the acceleration was 294 m/s^2, or about 30 g.
Here in America, I've seen rocky road flavored ice cream that has pretty much everything you described. Although I have not seen a rocky road in the form of a biscuit/cookie
As an American, I can confirm that rocky road is not just a UK thing
Rocky road ice cream was invented in the US. I believe Oakland, California.
Not sure about the cookie/biscuit. One probably was inspired by the other. I'd guess ice cream came second?
also, RAISINS?!?
They really nailed the visuals and sound in KSP 2, no doubt about that
It’s a shame that not much else seems to work….. 😂
One quick tip. When you are in Time Warp, you can use the / key to automatically drop out of Time Warp and go back to x1 speed. I don't know if this feature was in KSP1 but I don't remember it being there.
It was there in ksp1
Oh wow that is super good to know
@@I_Am_Infiniti Wow that is actually surprising. I know for a fact I never used it but when I first got KSP2, I went through the keybindings and saw it. I still sometimes find myself spamming the , key to get out of Time Warp but I believe I'll get used to it
@@hendrikpoggenpoel4508 I mean when you time warp, it literally says "press [/] to exit time warp", but I'm no stranger to missing instructions either, so I can definitely understand lmao
Edit: By time warp I mean when you timewarp to next maneuver or 'warp till here'
yea it was in 1 too.
I’d like to see more ksp 1 videos just as a breath of fresh air from all the ksp 2
Me too pal...me too...
same
I'd love to see Matt do the same mission in both as a comparison of how the games work
@@oneofmanyjames-es1643 same
matt, did you know that jool has a surface? (you cant return from there since no engines work at the pressure but you can land, but be aware that parachutes also dont seem to work). and also that Vall has a subsurface ocean you can enter by going to the ravine on the Jool facing side?
sub surface ocean??? Jool surface???
I knew about Jool's surface but didn't know about Vall! Super interesting. My next video will be a Vall expedition in KSP 1 lol so weird timing there
@@kaidenrodriguez8285sub surface ocean is probably an easter egg or exotic location, like the dres canyon but with water.
Now for the jool surface, i don't know if it's just another bug or it is intended to work like that. I should also mention that in ksp 1 cut content there's science reports in the landed state of jool, suggesting that there was at some point plans to make this a thing, that or it was just a devs joke for those who bugged the game that far.
Hold up, Vall has a *what* ?!?
@@GreendelDemon maybe it’s intentional, reminds me of beyond home gateway.
I love how you played the ksp 1 VAB soundtrack during the build.
To limit the wings flapping, i found that reducing the depth of the control surfaces helps. I think that it's repeatedly overshooting the target, so making is thiner allows smoother control.
I've had better results doing this as well, also designing planes that don't require SAS or just not using it at all. The issue is exactly what you say, it is overshooting, then oscillating too hard as it tries to correct.
The code that would do this autocorrection by overshooting then undershooting until its stable is called a PID controller which controls the hysteresis or in other words the oscillation you see there. It can easily be fixed with some fine tuning and some other considerations. They need to lower or fine tune the gains on these controllers, meaning the initial correction of pitch would either be a lower angle, or the flap movement would have to be slower and more methodical as to not change the pitch so rapidly. The rapid pitch change is both overshooting and causing drag related effects with the body and wings that compounds the issue.
The other thing they might need to do is modify the drag characteristics of the procedural flaps, especially since the large ones seem to have a wild effect on them. Maybe they can factor in the surface area of the flaps into these PID controller calculations in the future, make things more stable.
Sorry, engineers are boring I know, but the fact that I can see the solution in my head and its not there yet bothers me. I have been looking around the config files in the game to see if I can change it myself and maybe put out that info for others to try as well.
I don't have KSP2 so I've not been able to check this, but I read a post about the parts randomly falling off bug, and apparently in save files all parts have an ID number and a bug occasionally reverts the number to 0000-0000-0000 or something. If you can find the original numbers from an old unbugged save you can copy them across to your new save and it fixes the problem!
Keep up the good work, I really love your videos!
As rough as the Kraken is.. you handle it like a champ. All the while causing me to belly laugh out loud at the craziness. Thank you Matt top notch entertainment as always!

17:55 Just like I had with my recent Duna mission, you *did* have a periaps show up in Tylo's SoI! I've only ever seen it happen a couple times now.
That amount of thrust is pure insanity!
I feel like they have added lots of cool things and visual enhancements and I understand that it’s buggy and laggy because it is early access but also they have changed things that didn’t need changing, like the map screen or the camera controls in the VAB, and things like building fairings - these are all things that didn’t need “fixing” but I look forward to the future for what this game could become! 😊
High thrust, high efficiency engine, you say? I see the devs added Fusion torch drives into the game earlier then expected. Great success!
I want to build something like the Rocinante so bad
I love how the kerbals in the top right are just having a stroke at 21:52
Note: you can actually see what your periapsis will be when encountering a planet or moon in KSP2. Just not when focusing the body itself. Instead, look at your orbital line and you'll notice you have 2 PE marks, one of which will be your PE around the body you're going to encounter. You can also keep your mouse over it while thrusting to optimize your encounter (just not using the maneuver plan). There is also a mod already out that will fix it in place like in KSP1 so you don't need to keep your mouse over it.
Speaking of mods, there is also a maneuver node editor mod out already, which should make your life a lot easier.
Thanks for the video, glad that it sounds like you had fun making it.
Awesome video Matt 😁 those Kraken attacks are a nightmare - hopefully it's all fixed soon .
The Jool system is just majestic ❤️
you can actually see your periapsis of another SOI in the map view, it's just on your orbit in the current SOI. (you see a PE icon near the encounter location)
we have rocky road in America but almost exclusively as an ice cream flavor. great video Matt!
Are you ever gonna recreate your first vid, the Eve submarine in KSP2?
Just create a maneuver node that results in a collision with the body, then adjust it slowly until it just barely doesn't result in a collision. Then you are going to have a fairly close encounter.
It seems like the part detaches from the craft, but is still considered part of the craft. That causes the camera glitch because the camera focuses on the center of your vehicle. They really need to fix this and the VAB bug.
thsi video came up in my recommendations and oh god the nostalgia hit the second the first note of Approaching Nirvana started playing. I used to use it for background music so much back in the day while working.
I found using 'control surface' wings instead of regular 'wings' or 'stabilizer' in the rear helps with pitching issue. Seems the size of the control surface actually affects it.
Gotta love a video that's 5% mission to 95% working around the bugs. 🙂
Something that helped me with the flappiness of the wings was lowering the control authority a bit. It made my plane turn *very* slowly but I could actually control where I wanted it to go
My personal theory for what causes the SAS flapping is that they are using closed-loop PID control but either set the derivative gain too low or just didn't set it at all. Closed-loop control responds to differences between the demanded value and the real value. For instance, if the craft isn't pointing to the marker set on the nav ball, the control system sees this and tunes the control surface angles in response so the craft moves closer to the desired heading. A PID system does this using 3 'gains' - Proportional which affects how aggressively the system responds to a difference, Derivative which sees how quickly the system response is occurring and slows it down if it's too fast, and Integral which reduces settling errors based on where the system has settled before. For best response, you want a high proportional gain so the system responds quickly, but if it's too high this causes instability as the system over-corrects and has to correct its own correction, and you get some wobbling before it is brought under control at best, or exponential growth of the error followed by an explosion at worst. A derivative gain can be used to reduce this by checking if the system is responding too fast, but if it's too high it can slow down the response, so balancing this with the proportional gain is important (and hard). If they are correctly balanced you can get a speedy response without the overshoot problems, but this often takes some time to make work, time the devs probably weren't given. Integral gains are useful but not really as relevant in this situation.
I wouldn't be surprised if the way the devs were rushed to produce something releasable, they just whacked up the proportional gain so that SAS actually had some control over a craft, and ignored the derivative and integral gains (or just made them small) as implementing them is a pain and can be dealt with later after they have the rest of the critical physics architecture in place. This is almost certainly a crack theory based on me trying to fit a single module in mechanical engineering control theory (which I didn't even do that well in) into a real situation, so anyone who actually knows how to implement control theory in video games you are welcome to contest this.
The non-existent SOI trajectory thing is definitely a bug because it did appear for me when I first got a Jool encounter. I could even get a Tylo encounter while still in Kerbin's SOI. However, it did not work when I tried to go to Minmus.
Day 3 of asking mat to make an interplanetary flying wing SSTO.
Time to call in the blunderbirds & save the crew stuck on Tylo?
Matt, lovely video as always. I wonder since there's no atomspheric heating in KSP 2 at the moment. We could get a kerbal out on eva just above the karman line and de orbit the kerbal? The challenge being trying to land him back safely on kerbin with the kerbal's parachute. An even more difficult challenge, would be to land the kerbal back at the KSC.
"if it's not a bug they need to fix it"
Perfect description of the current state of the game
Matt and SSTOs, name a more Iconic duo, I'll wait!
Mhmm maybe Matt and the Kraken xd
Nice video as always dude!
"ghost riding the whip" got a good laugh out of me. Thanks for that
been having a blast with this glitch engine getting insane constructions into orbit, or getting to 1/100th speed of light
Thank you for all the content
Good to learn about a way to make spaceplanes, i cant wait to try it out
Kraken Drive!!! :D awesome video.
Rocky road ice cream definitely exists in the US. Very delicious, also awesome ksp video loved it until the end
Rocky Road definitely exists across the pond, at least in the midwest. Great video
Yessss, harness the Kraken! :D
Oh hey, the Mk2 bays open wider. I like that.
SAS is a servo system. Getting a servo system right is tricky.
Big flat areas? WOOHOO!
Fun to fly is always good. :)
Oh, KSP2 does copy/paste right! That's pretty rare, and it's great! :)
That was really fun to watch! :)
It's so weird and also beautiful to see this game run at a normal framerate. Gets me excited to play when the time comes.
* Lands on Tylo and destroys the engine *
* pause *
* Blunderbirds intro *
Haha this is perfect! I am just visiting laythe for the first time in ksp 1 before I go back to ksp 2 to visit and see the difference
LOL the rocky road ice cream ramble in the middle was great! XD can confirm that its a thing is the US im from missouri and Rocky road is actually my favorite ice cream.
14:52 "Hey did anyone chock the wheels...?"
All I could think of at 11:30 is Rammstein’s Du Hast, because I could see the Kerbals head banging away in the upper right of the screen!! 😂😂😂
matt you absolute legend i had been looking for the intro song forever!
I dig the use of KSP1 music overlayed onto the sped up footage
It's nice to see the base SSTO model of the mat as KSP2.
at 18:32 it actually shows the orbital line for your tylo intersect! I think it only works when you're NOT focused on the plant lol.
Here in the states we have *all the ice cream* so yes we do have rocky road lol. Also biscuits are like a dense but soft bread that one serves with soup or in a meat stew (usually turkey). Our word for what you in the U.K. call biscuits is cookies.
11:29 Look at the kerbals! They be jamming to some music🤣
British "biscuits": dry dull cookie.
'Murican biscuit: delicious, buttery, soft, heaven in your mouth.
😋
I am really glad the devs are as hyped about the resource collection and base building as I am. As soon as that gets implemented I'm totally getting this game. Rocky road ice cream is where its at!
Laythe is my favourite celestial body ever in any game and it looks so good in this one! I remember youre first laythe video can you like remake that in ksp 2?
Laythe isn't a planet.
@@_P2M_ The distinction between planet and moon is rather arbitrary, and largely immaterial in this case.
@@akiranara6404
You don't know what arbitrary means. If it was a distinction between a dwarf planet and a planet, sure, but a planet and a moon? No.
@@_P2M_ When you think about it, all of the planets are the moons of the Sun. So yes, the difference between "planet" and "moon" is quite arbitrary.
Anyway, the difference is still immaterial, because the commenter was gushing about how Laythe is their "favorite planet ever in any game", so whether or not Laythe really counts as a planet doesn't matter for the sentiment they were trying to convey.
@@_P2M_ its fixed now
So the Kracken has taken on the form of the late, great Alan Rickman?
"You dare use my own spells against me Lowne?"
I'd love to see you do a grand tour with this craft! I'd do one myself, but my pc can barely run KSP2
Yooooo this is sick
When the kraken makes all your ships lemons, don't make lemonade! Make the kraken take the lemons back! Get mad! I don't want your damn lemons! Matt's gonna get his engineers to invent a combustible lemon that'll burn your house down!
Entirely unrelated to the video, but looking at the landing site on your Laythe departure, I could swear it looked like the old Macey Dean colony site
17:20 We have rocky road ice cream here in the US. I'm quite a fan of it as well.
The classic KSP1 music still gives me the chill, I loved it so much... I hope someone can mod that in eventually.
At least the space part of it. Maybe KSP2 music will grow more on me as I spend more time in it.
Sudden and rapid disassembly ? Weren't they supposed to vanquish the Kraken =p
Also the ship fighting with itself and not keeping straight is super annoying. Just flying to the north pole of Kerbin in KSP2 was trying my patience ><
I hope they fix that soon.
Awesome video, thanks.
Yes, Rocky Road is a thing in the US, and it's amazing.
IIRC, "Digestive Biscuits" are like round Graham Crackers (but not as good). An American biscuit is a bread, and apparently close to a *savo[u]ry* scone? It is not sweet; it's just bread.
I discovered the jet engine reverse thrust issue naturally aswell. Never concidered using it for an engine or even knew it worked for the rapier in rocket mode though
This so so efficient, your deltaV whent up when you used fuel XD.
"In this household, we OBEY THE LAWS OF THERMODYNAMICS!"
the flapping back and forth in the air is from miss aligned roll I think because when you turn of roll control on the control surfaces it stops.
Hearing approaching nirvana in videos again does put a smile on my face
It took me a while to realize, that you put in the KSP1 Soundtrack. 😅 Until that moment I had this „there is something wrong“ feeling in my guts. 🙈
With these proportions and in this color scheme this plane kinda reminds me of some sort of retrofuturistic muscle car
Matt Great video good job
okay this is amazing and im going to try this lol
for the first time today, I cried over the Mk 3 SSTO as it disintegrated on the runway as soon as it spawned lol
I would love to see like a modular space shuttle heat tile system for the wings and all of the space plane parts. The space shuttle cockpit has heat tiles, but they are only on that one part so it doesn't really look right. If it's just a cosmetic thing that would be cool, but it would be cooler if they were actually functional and ablative.
Matt's already pumping out KSP 2 content!
It seems a tightly-woven mesh of struts has some effectiveness in deterring kraken attacks as a sort of "strut-chainmail" or "kraken-mail."
Yes we have rocky road in Australia; Its a flavor consisting of chocolate nuts and marshmallows and sometimes other things.
Very cool vid bro
Rocky-road is basically the floor sweepings from an ice-cream factory.
I’ve been getting around the missing orbit line by clicking out of the maneuver node and checking my periapsis around the target body. Then adjust at the end of the burn until I get the periapsis I want,
Also, there is a way to deal with a different glitch where your orbit line never shows up in the flight preventing you from doing a maneuver node. The game in that case thinks you are still on the launch pad. You can go into the save file and change the vessel status from landed to orbiting. I google searched for that solution.
A good landing is when everyone survives, a very good landing is when the plane is fully intact too.
I ran into this bug as well while trying to make a F22, I pressed space and it just took off backwards. Saved it as “bug” for future use
27:27 control surfaces start flapping
Me think of the plane flapping it's wing meme😂😂😂
love your vids
In America we have Rocky Road ice cream which is a flavor of vanilla or chocolate ice cream with what I guess now are “rocky road biscuits” or little chunks of chocolate, marhsmallows, nuts, and other stuff
Now we can revisit Life on Laythe!
amazing video!
I'm Japanese so I have no idea what they're talking about, but the video itself is a lot of fun to watch!
Love the videos
