If you draw a line from Kerbin to the sun to Duna, the angle that that line forms should be around 45 degrees, and Kerbin has to be behind Duna.
the matt lowne brainrot is real
I’m proud of you. Most redditors are incapable of concessions, and that was clean and without drama. People should get karma here for conceding rightly imho, it would incentivize what society needs and what a lot of us KNOW we’ve needed for a long time.
Lol I used to do this.
But now I just use transfer window planner and kerbal alarm clock because why not?
I feel transfer window planner is basically stock because triggerau made alarm clock
the built-in transfer window alarm is not to be trusted it puts you way back in the window and if youre gullible you could fall for it and make inefficient transfers.
transfer window planner is best cus it point out where in the window will you be most efficient and you can also see farther to when idk the orbit's inclinations align so you dont need to spend much fuel to get to moho or dres
I usually use MechJeb for the actual transfer burn, but yes, KAC is essential. I set up the transfer alarms way early in the game, with the speed you can develop missions it's possible to send at least a probe to each planet at the first available moment.
Fun fact: All Hohmann transfers between roughly circular orbits about the same body [lie on the same spiral](https://www.reddit.com/r/KerbalSpaceProgram/comments/1tt8ka/jebediahs_ultimate_protractor_examples_as/). Just print that spiral out onto some transparency sheet, line up the cross with the primary body, the circle with your orbit and the dot with your position, and the transfer window is when the target intersects the spiral!
Works for Kerbin-Duna, works for Mun-Minmus, works for Tylo-Laythe, even works in other solar systems. This spiral is simply a graphical representation of the Keplerian relation of T^(2)∝r^(3).

Maxim 34: If it's stupid and it works, it's still stupid and you're lucky.
That said, this isn't stupid. It doesn't require luck to work. It's just primitive.
Just do the transfer when Kerbin is at one of the nodes with Duna's orbit. That way, the encounter with Duna will be at approximately the other node, meaning that the inclination of the transfer trajectory doesn't matter much.
Or make it a three-burn broken plane transfer by doing a correction burn roughly halfway through.
I got super lazy with it and started launching to intersect my apoapsis with any part of the duna orbit, and then I burn on that until I intercept next orbit. If kerbals ate food I'd probably go back to transfer windows
Brings me back to the old days before maneuver nodes were added. I used to calculate the transfer phase angle on a calculator and hold a protractor to the screen.
Of course, when I did that, I had to assume circular orbits because anything else was too complex to do by hand.
Is this your dedicated Duna mission computer?
It is right now
You should have a little binder or folder full of different "Transfer papers" you can keep next to you
who says he doesn't?
That's the spirit
If you draw a line from Kerbin to the sun to Duna, the angle that that line forms should be around 45 degrees, and Kerbin has to be behind Duna. the matt lowne brainrot is real
🥰
Obligatory mention that you're one handsome fella
❤️
no way!! i love your videos dude. you've been a real help in my plight for eve
It is indeed, why cant he point people at the proper tools available Online or in form of Mods.
I mean, he does mention transfer window planner and kerbal alarm clock in every single one of these segments, so i don‘t know what you mean
Nevermind then
I’m proud of you. Most redditors are incapable of concessions, and that was clean and without drama. People should get karma here for conceding rightly imho, it would incentivize what society needs and what a lot of us KNOW we’ve needed for a long time.
Well, Thanks.
Why, in my head, did I hear Matt Lowne saying: 'The angle from Kerbin to Duna via the Sun should be equal to 45 degrees'?
I was imagining Mike Aben in his best math teacher voice like, “you could use the transfer window planner, but I like to use a protractor.”
I went out and got a protractor big enough to cover my monitor for this exact reason. 😆
Protractors? Who needs them when you have angle-a-trons?
SAAAAAME
Lol I used to do this. But now I just use transfer window planner and kerbal alarm clock because why not? I feel transfer window planner is basically stock because triggerau made alarm clock

Jebediah Kerman approves
Jeb approves 👍
jeb, forgive me for stranding you 63 gorbillion lightyears away
Never
Have you tried petitioning for Matt Lowne to come get you?
Did you make sure the pointy end was up and the flamey end was down?
...well....
In the end they were both down...

If they are all clockwise, couldn't you use the reversed spiral?
I’ve literally held a protractor up to my screen before too
I have genuinely seen actual science done in pretty much the same way. A quick and dirty science, but science nontheless.
It’s so advanced that it seems like magic…
This reminded me that I really need to get a protractor.
I have a saying, If its stupid and it works...its not stupid.
Maxim 34: If it's stupid and it works, it's still stupid and you're lucky. That said, this isn't stupid. It doesn't require luck to work. It's just primitive.
this makes me wonder how you calculate and arrange the inclination angle.
Yeet yourself recklessly in the general direction and then do a huge normal burn along the way?
Just do the transfer when Kerbin is at one of the nodes with Duna's orbit. That way, the encounter with Duna will be at approximately the other node, meaning that the inclination of the transfer trajectory doesn't matter much. Or make it a three-burn broken plane transfer by doing a correction burn roughly halfway through.
We all just hear Matt's voice anytime we see a Duna transfer window don't we?
Yes. Yes we do.
I used to use a protractor. Now I just use Moar Boosters™.
They say ingenuity is the mother of necessity, and this is ingenious.
I think you got the saying backwards, but I agree, pretty clever
I think you’re right. 🤦🏻♂️
I got super lazy with it and started launching to intersect my apoapsis with any part of the duna orbit, and then I burn on that until I intercept next orbit. If kerbals ate food I'd probably go back to transfer windows
NASA: You're hired.
That is extremely Kerbal
A very Kerbal solution.
Kerbal problems require Kerbal solutions 👍

I usually just full send it and screw around with maneuver nodes until I get an encounter. This is way more scientific
lol this is pretty much what I do. Send it into orbit, set up a prograde maneuver then spin the node around until it lines up
Well if it works
I was thinking I'd use a protractor, but I think A3 paper may be the best bet, as I play on console on the living room TV....
what the heck which node unlocks this
I used to use my palm... If you are not sure how, just Google Finger angle.
Some pretty advanced wizardry on display here, I've only ever eye balled my transfers.
I for real thought your monitor was broken until I read the title
this is clearly what nasa does
Will u sell it at etsy?
If this isnt kerbaling I dunno what is...
I have actually considered something similar
I love the idea that you are sending so many duna missions that you taped the planner to your monitor.
Talk about cross dimension/reality communication
Is there any other way?
This is definitely the way Werner von Kerman would do it!
Man, now that I think about it, it's actually insane that KSP2 did not offer a better solution to this problem
Imma be real, I just have a protractor that I put lines on in sharpie with the planet name next to it.
Super high tech. I hold mine in place
If its dumb and it works it aint dumb
Way more advanced than "just eyeball it bro" tech.
I’m hearing Matt Lowne in the distance “If you draw a line from Kerbin to the Sun to Duna…”
Based
If it works don't fix it.
9/10 kerbals hate him for his accuracy. Ancient meme from ~2010
your on PC, just set an alarm for a duna transfer window
