Probably not even possible in reasonable time frames, but its ksp you can always force your kerbals to sit in the same small command pod for 16300 years
It’s possible, if you get a gravity assist off tylo and jool. Using tylos gravity to accelerate as well as jools. It’ll shoot you out at escape velocity for kerbol. So if you go via a Eve-Kerbin gravity assist to get to Jool and then the Tylo-Jool for Kerbol escape you can get interstellar for minimal delta-v usage. I’d also suggest getting the Jool encounter after your apoapsis so that way you’re gaining velocity from ‘falling’ to your periapsis, it’s not a massive gain relatively but it’s more likely to boost you to interstellar speeds than if you encountered Jool closer to your apoapsis. Also if you time it right you can gravity assist off the mun to get down to Eve I’m pretty sure.
Watching in fascinated horror as Matt’s 88 year mission gets him further through the tech tree than I am in my Exploration Mode save, which is about to embark to Duna.
I can imagine Matt drawing blood, but with a twist. Instead of going for the arm, he tells the patient that he is doing the expert mode today. That entails going into an ankle draw by way of the ear canal. With "gravity assists" at the aorta, kidney. Gallbladder back up to the heart allowing him to get down to the pinky tow. Then it's just a few small gravity assists to the inner ankle vein.
What I have learned when it comes to gravity assists is if you pass "behind" an object relative to the direction it's orbiting it'll speed you up. If you pass "in front" relative to the direction it's orbiting it'll slow you down.

You are basically correct on gravity assists. The other thing that goes overlooked is the fact that redirecting your kinetic energy by changing your flight path angle can make it _appear_ that you have gained or lost a ton of energy. Flying by a distant attractor obviously changes your direction, so a well-executed gravity assist will send you flying in the right direction with a little bit more or less energy stolen from or donated to the parent body.
When Voyager 2 passed Jupiter, using a gravity assist, it slowed Jupiter's orbit down by 1-2 centimeters every several hundreds of millions of years - not sure the exact calculation, but heard it from a documentary. Crazy!
KSC: Don't worry Jeb, this is our first mission, the bar is low so you can get used to flying. No need for any... "Jeb" incidents. Jeb: Hold my boosters...
I have an idea for a Vall base, if you're willing to listen: -A surface mining base -A large unfolding solar panel probe in high Vall orbit -A reusable craft to go between them that has large battery bank, can deliver power from the solar probe, and is fueled by the ore extracted from the mining base (this keeps the base charged up) Thanks for considering!
what would have been fun, is while Jeb was enroute to Eeloo, the engineers continued to develop the tech and create a faster and more efficient vessel to Eeloo, and when Jeb touched down, his grandchild would have been here, waiting for him and saying "you're late, Gramps!"
I feel like this is a part of KSP2 (and KSP1 for that matter) that doesn't get 'gamified' enough. Planning out missions to happen in between other concurrent missions. In the 90 years it took Jeb to make this trip the space service absolutely could have done other missions while waiting for Jeb to reach the next manuever node.

I remember watching a Scott Manley video, back in an early version of ksp 1, and if i remember correctly squad put a challenge out to him about unlocking the entire tech tree on the first flight before they tweaked it so it wasn't so easy. My point being it seems the crown has passed on to you as being the best and most capable player for ksp 2, as far as reputation from the devs goes
Great explanation of the physics behind gravity assists! I also usually like to point out that the direction of the vessel's velocity changes, which crucially increases its angular momentum around the sun, as otherwise angular momentum is conserved throughout the entire orbit. Funnily enough, I was just solving a problem from the astronomy Olympiad on this subject, and it really requires some lengthy calculations:)

I'd like the "a couple things at a time" approach. I usually try and cover a couple contracts per mission, the contracts group in a way that makes that make sense... That what I'd like to see. But challenge yourself to do it in as efficient a way as possible. Kinda hope future KSP will reward things like that...
About the resource management, it would be interesting to include a difficulty slider that would let you ignore things like food and life support on the low end and include things like garbage management or Kerbals needing to rotate in and out of missions every so often on the high end.
Performing a gravity assist involves utilizing the gravitational pull of a celestial body to boost a spacecraft's velocity. To execute it: 1. Approach the celestial body in the direction of its motion. 2. Use its gravity to increase the spacecraft's speed. 3. Exit in a direction opposite to the body's motion.
Matt, you are an absolute gem to watch and just as a representative of how the ksp community is as a whole. You are of course a hell of a player but you also are dependable and always there for us with another impressive launch. If Scott Manley is the father of the KSP community, you are our wonderful mother. Always there with a meal of a launch for us to consume, making sure we don't go hungry.

Matt can u ask the developers to display the delta v applied in each direction on the proposed maneuver node adjuster. Idk if that makes sense but on each directional node you would see a little number next to the symbol with the particular velocity change in that direction. This could have a feature where you could edit these values by inputting delta v changes manually with a keyboard for really fine adjustments
yeah that would be awesome. or even a way to reset the delta-v to 0 along specific axes. i wish we could just control them on the keyboard, with like ijklhn like the rcs
Thank you Matt, after the science update I started playing KSP2 and watching your videos again. The last time i had any sort of KSP interaction was when the KSP2 announcment trailer was released. I really enjoy listening to your videos. And yes, I think most people would agree that your longer videos are fun too.
At 7:18 I looked and realized that somehow I’m not even subscribed. I’ve been watching and learning from your videos for like, a year now! Crazy how that happens!

1) Congratulations on having the first cute whisky. 2) Planet coaster ramblings are great and I watched all of them. 3) Thank you for apologising about the gameplay getting in the way of the narration 😀 4) "Safe" re-entry = Not dead = good enough 😁
I could never replicate what you have done in this video. Last time i had a gravity assist, it was unintentional, by the Mun. (The planner didn't show the encounter.) It yeeted me out of the entire solar system. Naturally, with no fuel remaining.
Your explanation of gravity assists is great - the reason why you can take energy away like that has something to do with the fact that the body is spinning, so it gives you a push. Otherwise you'd lose all the energy gained on leaving. This video is basically the grand tour by Reach in RSS, except it doesn't go inwards. Awesome. The only gravity assists I've done in stock KSP is the Tylo braking one. Edit to clarify, by spin I meant the direction of orbit around the parent body, not the rotation of the planet.
Gravity assists still work the same way with Venus (which spins backward) and the Moon (which spins very slowly). Relative to the assisting body, your entry and exit speed is the same (just is a different direction), but that change in direction can be in the direction of the orbit, so relative to the parent body you exchange momentum with the assisting body.
Matt, I have to say...your videos are great...I like space travel and the way you do your missions is incredible...thank you for giving me incredible content to watch!
As for the playthrough series, i would recommend you matt to do both. Set days that this particular day you'll do whatever you wanna do and this particular day you'll play like us peasants
I've just finished watching most of Matt's KSP 2 videos within a few days, and I'm very thrilled to see major bug occurrences have lessened quite a bit. The dev team is doing great work and I'm very hopeful for the future of KSP 2. It's great having people like Matt making unbelievable accomplishments like in this video. For science!

This is the best video ever published to youtube solely due to the fact that it includes a british man saying, "I'm more excited, to be honest, for the colonies [...]"
I’ve seen a lot of your content, but this one was very impressive Matt lol. So far my best achievement in KSP is landing and returning from Duna. I was so proud! 🚀
This was the vid that finally got me into gravity assists. Just did Principia Kerbin > Eve > Kerbin > Kerbin > Jool > Kerbol escape for like 2km/sec Please applaud
*Me not bothering to check how long the video is and needing to leave in about 30 minutes.* Matt graciously saying at the 3:45 mark: "So if you don't fancy sticking around for the better part of an hour..." Thanks, Matt, for saving me from myself.
I don't comment often on UA-cam, but I HAVE to say... Thank you for mentioning the "next orbit" button. It's been killing me not having it, yet I hadn't seen anyone mention it anywhere on Reddit or anything. I'm glad a big name in the game like yourself has mentioned it! Thanks for all the videos!
You should do a KSP 2 tutorial that goes into many of the things the training center glances over, like Docking, Rendezvous, Transfer Windows, Crew Management, etc
Honestly for an exploration mode playthrough I think it'd be great to do a "roleplay" so to speak. Budget stuff out behind the scenes and try to build up your space program in a way that feels natural. First launch make it to a sub-orbital trajectory, then make a full orbit, send out some probes to the mun and minmus and send some probes to the other planets around Kerbol. Maybe even make it a more genuine tutorial? Like using episode one (sub-orbital and orbital rocket) to explain the basics like distributing weight, and how ascent profiles work. KSP 2 doesn't have a whole lot of teaching based content for it yet. And I think everyone would appreciate seeing it start to grow like it did for KSP 1.
Great video! For someone like me who is still struggling with gravity assists in KSP1 after all this time, it was really instructive to see in detail how you are doing them, how you make your maneuver nodes and so on.
I'd say the best place to learn gravity assists is just messing around in the jool system. The smaller scale and closer moons make understanding each maneuver easier.
I really like the Matt’s content and I liked the video and I’m a long time subscriber. Jokes aside, great mission and your explanation of gravity assists was pretty good!
15:00 Where does this extra energy come from? (gravity assist question) Every action has an equal and opposite reaction. It comes from the planet you'rere sling-shotting from. Your tiny mass (spacecraft/ jeb/ fuel/ snacks) is accelerated a HUGE amount by the planets gravity, where as the huge mass of the planet is decelerated by a miniscule amount. To get your head round this, imagine trying to slow kerbins (or earths) rotation with a rocket... How many 1000's of Starship boosters + Saturn 5 1st stages are you going to need to change the plants spin by just 1mph?
the way you explained gravity assists makes me think that as soon as you get into a planets gravity its like you're attached to that planet and the planet is a rocket speeding you up
Matt you're an amazing youtuber man , i never knew that's how gravity assists work and it now makes total sense , net energy out of nothing would be impossible so smth as small as a sat stealing orbital energy to go faster wow learned smth lol thanks! that's pretty cool
The best way of understanding gravity assists is to play universe sandbox, where doing a gravity assist actually slows down the celestial body you are assisting off of and it becomes visually apparent what's happening. If an object with the perfect mass, vector and velocity were to gravity assist off the Earth, It could reduce our orbital velocity to fall directly into the sun.

11:48 it'd be fun if there was a sort of "trip planner" in the game so you could work out your orbits and gravity assists, and landing etc, and get a requirements breakdown per stage/length of trip. Then have an option to break it up into stages and moving the parts between them so that the system can calculate how much fuel you'll need for the other parts of your trip.
you could even have maneuver plans be "stages" in the trip planner! another fun idea would be a more detailed stage designer where you can insert specific actions. kinda like turning every stage into an action group.
Although I’m excited to hear you talking about a chapter-by-chapter “Let’s Play” for KSP2, the game definitely isn’t finished yet. So be prepared to do it all again when Nate changes the missions in a future update!
The mod Maneuver Node Controller has been essential for me, it's basically the advanced maneuver function from KSP. I also use Flight Plan to instantly create run of the mill maneuvers like circularising or raising/lowering orbits (and it's a godsend for orbital intercepts which I hate doing manually). It takes a lot of the tedium out of the game for me and lets me focus on building rockets, doing science and completing missions.

gravity assists, especially when trying to chain multiple together, are extremely hard to calculate as theres so many factors that go into them, and small changes to the burn can cause massive changes after the assist. it would be great to see, but i doubt it will be added. if they do, theyd need an automated burn system aswell to ensure that the assists are accurate

40:00 the amount of dV and possibly also the "path" will depend on the date even if you don't use gravity assists. So the game would have to at least calculate the minimal dV requirements for a desired time frame. (get to the destination within 3 years, use minmal dV )
Wow, this is a great video Matt. I'm gonna press the like button and I've also made sure that I've hit subscribe because I really like the content that you make.
Fine tuning after large maneuvers or gravity assists is something that happens in real life, too. Frequently you'll hear shortly after launch that a satellite's expected life is extended because the launch vehicle was very accurate, so the satellite saves some fuel from fine tuning that they can use to maintain orbit. They're still making small adjustments, though. If you're doing gravity assists on the way out and back, you're not really stealing energy, just borrowing it, although you might return some of it to different planets. And anyway, there's many factors you don't think of that have a greater effect on a planet's orbit than that. Asteroids can have measurable changes to their orbit when measured over years just because their color changes how much light they reflect or absorb and emit as heat.

why would they do that though? it's not like they sell you a 5$ DLC for "skip orbit button, +10fps and Farings that occlude their content from heating" @@vicroc4
@@vicroc4quit being such a pessimistic asshole
Or it's just... not in the game yet?
I remember watching a Scott Manley video, back in an early version of ksp 1, and if i remember correctly squad put a challenge out to him about unlocking the entire tech tree on the first flight before they tweaked it so it wasn't so easy. My point being it seems the crown has passed on to you as being the best and most capable player for ksp 2, as far as reputation from the devs goes
I dont know, IMO that title goes to Stratzenblitz
@@thegreatchipman who is that? This happened around the time ksp was in alpha or beta release
@@glenns7252 guy did some ridiculous project, like eeloo on srbs, and bridging the Dres canyon
Nowadays, there's a lot of "best" Kerbal players, but some of the top names are going to be Stratzenblits75, Bradley Whistance, and Lt. Duckweed
Great explanation of the physics behind gravity assists! I also usually like to point out that the direction of the vessel's velocity changes, which crucially increases its angular momentum around the sun, as otherwise angular momentum is conserved throughout the entire orbit. Funnily enough, I was just solving a problem from the astronomy Olympiad on this subject, and it really requires some lengthy calculations:)
As much as I really love to learn about space and how it works, the spaghetti formulas make it really difficult.
@@FormerFofcaStudentAlt it's one of those things that's relatively easy to intuitively understand, but hard to represent in a simple mathematical way. which really sucks.
I love listening to Matt go COMPLETELY off subject. It's very wholesome.
As an astrophysics grad student, your explanation for gravity assists is pretty good
Wow this is a great video, Matt! I'm going to press the like button, and I've also made sure that I've hit subscribe, and I rung the bell, 'cause I really like the content that you make, and I'd love to get notified when you make content!
Takes me back to the pre 1.0 days of KSP1 where people where getting to Minmus launch 1. Feels good to have the swivel back
Make the exploration series the ‘intended’ way, to be a successor to your lowne aerospace turtorial series on ksp 1
Please... I have the brain of a mollusk and need all the explanations ;)

Which, by the way guys, is every Monday for space news, every Saturday, usually, for kerbal space program 1 and 2.
Matt has 100% not paid me to say this.
Also Matt, I’ll expect my cheque in the mail

I'd like the "a couple things at a time" approach. I usually try and cover a couple contracts per mission, the contracts group in a way that makes that make sense... That what I'd like to see. But challenge yourself to do it in as efficient a way as possible. Kinda hope future KSP will reward things like that...
they've mentioned that eventually you'll have to spend resources to build rockets, which should be a good efficiency incentive.
About the resource management, it would be interesting to include a difficulty slider that would let you ignore things like food and life support on the low end and include things like garbage management or Kerbals needing to rotate in and out of missions every so often on the high end.
Performing a gravity assist involves utilizing the gravitational pull of a celestial body to boost a spacecraft's velocity. To execute it:
1. Approach the celestial body in the direction of its motion.
2. Use its gravity to increase the spacecraft's speed.
3. Exit in a direction opposite to the body's motion.
Maybe you're thinking that gravity assists are dumb but, when we get interstellar travels they will regret they words
Matt, you are an absolute gem to watch and just as a representative of how the ksp community is as a whole. You are of course a hell of a player but you also are dependable and always there for us with another impressive launch. If Scott Manley is the father of the KSP community, you are our wonderful mother. Always there with a meal of a launch for us to consume, making sure we don't go hungry. You stood up for us when ksp 2 felt like too much of a letdown. And you just make me happy when I see your videos. Keep it up momma matt!

It's a game with missions!
I would love to see a "as the developers intended" playthrough of KSP 2!!! I'm struggling on a few of the pieces and would love to be able to see someone who is much better at KSP 2 do it!!!
I really like your style of video, it's nice watching some relaxing KSP gameplay and listening to your (somewhat tangential) commentary.
SOMEWHAT?! Matt Lowne is famous for is 179° tangents! :D

Matt can u ask the developers to display the delta v applied in each direction on the proposed maneuver node adjuster. Idk if that makes sense but on each directional node you would see a little number next to the symbol with the particular velocity change in that direction. This could have a feature where you could edit these values by inputting delta v changes manually with a keyboard for really fine adjustments
yeah that would be awesome. or even a way to reset the delta-v to 0 along specific axes. i wish we could just control them on the keyboard, with like ijklhn like the rcs
Thank you Matt, after the science update I started playing KSP2 and watching your videos again. The last time i had any sort of KSP interaction was when the KSP2 announcment trailer was released. I really enjoy listening to your videos. And yes, I think most people would agree that your longer videos are fun too.
At 7:18 I looked and realized that somehow I’m not even subscribed. I’ve been watching and learning from your videos for like, a year now! Crazy how that happens!
Matt, never apologize for making long videos for us. Long videos = you rambling about stuff, which is what true content is.
Wow, this was a great video, Matt; I'm gonna press the like button and I've also made sure that I've hit subscribe, and I've rung the bell, because I really like the content that you make.
18:06 it will most likely become a feature, it might count towards collecting atmospheric samples at different altitudes
1) Congratulations on having the first cute whisky. 2) Planet coaster ramblings are great and I watched all of them. 3) Thank you for apologising about the gameplay getting in the way of the narration 😀 4) "Safe" re-entry = Not dead = good enough 😁
I could never replicate what you have done in this video.
Last time i had a gravity assist, it was unintentional, by the Mun. (The planner didn't show the encounter.)
It yeeted me out of the entire solar system. Naturally, with no fuel remaining.
Your explanation of gravity assists is great - the reason why you can take energy away like that has something to do with the fact that the body is spinning, so it gives you a push. Otherwise you'd lose all the energy gained on leaving.
This video is basically the grand tour by Reach in RSS, except it doesn't go inwards. Awesome.
The only gravity assists I've done in stock KSP is the Tylo braking one.
Edit to clarify, by spin I meant the direction of orbit around the parent body, not the rotation of the planet.
Gravity assists still work the same way with Venus (which spins backward) and the Moon (which spins very slowly).
Relative to the assisting body, your entry and exit speed is the same (just is a different direction), but that change in direction can be in the direction of the orbit, so relative to the parent body you exchange momentum with the assisting body.
the assist energy doesnt come from an objects rotation but from its orbital energy
I don’t think it’s the spinning
Matt, I have to say...your videos are great...I like space travel and the way you do your missions is incredible...thank you for giving me incredible content to watch!
As for the playthrough series, i would recommend you matt to do both. Set days that this particular day you'll do whatever you wanna do and this particular day you'll play like us peasants
I've just finished watching most of Matt's KSP 2 videos within a few days, and I'm very thrilled to see major bug occurrences have lessened quite a bit. The dev team is doing great work and I'm very hopeful for the future of KSP 2.
It's great having people like Matt making unbelievable accomplishments like in this video. For science!

You make great KSP videos, but I'd watch anything you make. You're narration could make anything entertaining. Great work dude.
13:26 The only reason why people love to respond to your big long videos is because they become like a podcast and its actually quite fun to hear about your life experiences
And here I am stuggling to get into Orbit around Kerbin and you do Eloo with no tech at all. I got a lot of relearning to do. well done Matt.
This is the best video ever published to youtube solely due to the fact that it includes a british man saying, "I'm more excited, to be honest, for the colonies [...]"
15:00 - love the energy from nothing discussion!
That little angle you put there really helped me all lot thank you so much matt!!!¡!!!!!!!! God bless you you Saint!
As a new player to KSP, a lets play from someone like you would be greatly appreciated.
I’ve seen a lot of your content, but this one was very impressive Matt lol. So far my best achievement in KSP is landing and returning from Duna. I was so proud! 🚀
This was the vid that finally got me into gravity assists. Just did Principia Kerbin > Eve > Kerbin > Kerbin > Jool > Kerbol escape for like 2km/sec
Please applaud
*Me not bothering to check how long the video is and needing to leave in about 30 minutes.*
Matt graciously saying at the 3:45 mark: "So if you don't fancy sticking around for the better part of an hour..."
Thanks, Matt, for saving me from myself.
I don't comment often on UA-cam, but I HAVE to say... Thank you for mentioning the "next orbit" button. It's been killing me not having it, yet I hadn't seen anyone mention it anywhere on Reddit or anything. I'm glad a big name in the game like yourself has mentioned it!
Thanks for all the videos!
You should do a KSP 2 tutorial that goes into many of the things the training center glances over, like Docking, Rendezvous, Transfer Windows, Crew Management, etc
Didn’t even land at the KSC??!? What have you become Matt, you showed the devs this. /jk - incredibly impressive stuff.
Wow this is a great video Matt I will make sure to like and subscribe to support this content
You should try the mission about landing 10 kerbals on Eve and come back. Only you can do it!
Honestly for an exploration mode playthrough I think it'd be great to do a "roleplay" so to speak. Budget stuff out behind the scenes and try to build up your space program in a way that feels natural. First launch make it to a sub-orbital trajectory, then make a full orbit, send out some probes to the mun and minmus and send some probes to the other planets around Kerbol. Maybe even make it a more genuine tutorial? Like using episode one (sub-orbital and orbital rocket) to explain the basics like distributing weight, and how ascent profiles work. KSP 2 doesn't have a whole lot of teaching based content for it yet. And I think everyone would appreciate seeing it start to grow like it did for KSP 1.
while carnasa went crazy with moar boosters, you really put in the work with the gravity assists with a really elegant rocket
Great video! For someone like me who is still struggling with gravity assists in KSP1 after all this time, it was really instructive to see in detail how you are doing them, how you make your maneuver nodes and so on.
I'd say the best place to learn gravity assists is just messing around in the jool system. The smaller scale and closer moons make understanding each maneuver easier.
I really like the Matt’s content and I liked the video and I’m a long time subscriber.
Jokes aside, great mission and your explanation of gravity assists was pretty good!
15:00 Where does this extra energy come from? (gravity assist question)
Every action has an equal and opposite reaction.
It comes from the planet you'rere sling-shotting from. Your tiny mass (spacecraft/ jeb/ fuel/ snacks) is accelerated a HUGE amount by the planets gravity, where as the huge mass of the planet is decelerated by a miniscule amount.
To get your head round this, imagine trying to slow kerbins (or earths) rotation with a rocket... How many 1000's of Starship boosters + Saturn 5 1st stages are you going to need to change the plants spin by just 1mph?
Yup, your explanation was pretty much spot on.
the way you explained gravity assists makes me think that as soon as you get into a planets gravity its like you're attached to that planet and the planet is a rocket speeding you up
I'm hoping Jeb was just scouting where to make the prisoner colony for "Exile on Eeloo"
I would still love to see planet coaster on your second channel, I actually discovered ksp because of neptune tower
Matt you're an amazing youtuber man , i never knew that's how gravity assists work and it now makes total sense , net energy out of nothing would be impossible so smth as small as a sat stealing orbital energy to go faster wow learned smth lol thanks!
that's pretty cool
The best way of understanding gravity assists is to play universe sandbox, where doing a gravity assist actually slows down the celestial body you are assisting off of and it becomes visually apparent what's happening.
If an object with the perfect mass, vector and velocity were to gravity assist off the Earth, It could reduce our orbital velocity to fall directly into the sun.
Of course you can use gravity assists to break, I mean breaking is just negative acceleration, if you define your currect velocity as positive.

11:48 it'd be fun if there was a sort of "trip planner" in the game so you could work out your orbits and gravity assists, and landing etc, and get a requirements breakdown per stage/length of trip. Then have an option to break it up into stages and moving the parts between them so that the system can calculate how much fuel you'll need for the other parts of your trip.
you could even have maneuver plans be "stages" in the trip planner!
another fun idea would be a more detailed stage designer where you can insert specific actions. kinda like turning every stage into an action group.
Although I’m excited to hear you talking about a chapter-by-chapter “Let’s Play” for KSP2, the game definitely isn’t finished yet. So be prepared to do it all again when Nate changes the missions in a future update!
It's really still an alpha, because it isn't feature-complete. yet.
The mod Maneuver Node Controller has been essential for me, it's basically the advanced maneuver function from KSP. I also use Flight Plan to instantly create run of the mill maneuvers like circularising or raising/lowering orbits (and it's a godsend for orbital intercepts which I hate doing manually). It takes a lot of the tedium out of the game for me and lets me focus on building rockets, doing science and completing missions.

Hi Matt! On the topic of what you were talking about around the 7:00 mark, maybe in the future you can do mission contract related challenges like seeing how far you can get in a single launch or maybe a speed run of a section or sections. You have such a cool skill in this game and this and it would be so cool to see time related challenges :)

One thing that would really help with missions like this is some kind of in game gravity assist planner
oh my god.
i hope they add this, or at least a modder does
gravity assists, especially when trying to chain multiple together, are extremely hard to calculate as theres so many factors that go into them, and small changes to the burn can cause massive changes after the assist. it would be great to see, but i doubt it will be added. if they do, theyd need an automated burn system aswell to ensure that the assists are accurate

40:00 the amount of dV and possibly also the "path" will depend on the date even if you don't use gravity assists. So the game would have to at least calculate the minimal dV requirements for a desired time frame. (get to the destination within 3 years, use minmal dV )

a let’s play series where you do all the intended missions sounds really cool to me
My first use of the skip orbit button was to get to Minmus. I wanted to encounter it when it crossed the plane of Kerbin's orbit.
Loving your work! And now I'm off to catch up on your planet coaster series'!
Fine tuning after large maneuvers or gravity assists is something that happens in real life, too. Frequently you'll hear shortly after launch that a satellite's expected life is extended because the launch vehicle was very accurate, so the satellite saves some fuel from fine tuning that they can use to maintain orbit. They're still making small adjustments, though.
If you're doing gravity assists on the way out and back, you're not really stealing energy, just borrowing it, although you might return some of it to different planets. And anyway, there's many factors you don't think of that have a greater effect on a planet's orbit than that. Asteroids can have measurable changes to their orbit when measured over years just because their color changes how much light they reflect or absorb and emit as heat.
