Where's Scott Manly when you need him? Seriously though, Scrapman did really well figuring it out. There's a huge difference between following a tutorial and doing it yourself.

[@fiercedeitygaming7885]

and doing it yourself while following yourself doing the tutorial

[@agapetus1]

I know that way too well.

[@redvemr]

So some tips for orbits: when you get to 5000 m ASL, turn to 70°. Once the green arrow overlaps with the white one, enable prograde lock. The reason the tutorial had you throttle off for a bit is because the burn to circularize the orbit is most efficient at the apoapsis. There is a number, time to apoapsis and a number for burn time, when you are half your burn time away, lock 0° and burn. that way you spend the most time close to the apoapsis while burning. congrats on what you just did and knowing to control things at the apo/peri apsis.

[@mattmays9063]

Congratulations on figuring that out independently and being resourceful enough to remember to fall back on your tutorial video segment. You're a very logical person with an exceptional gift for imagination and problem-solving. I watched hours of Scott Manley and Matt Lowne videos to learn how to do what you're doing in KSP. You must consider the amount of acknowledgment that this should bring you. If you're interested ScrapMan, if you have free time, you can check out Scott and Matt's videos. They do an INCREDIBLE job of explaining those numbers, what they represent, and how you can use them to predict your crafts potential.

[@shanemaddocks703]

Dude I agree he did well. I tried to explain orbital mechanics to my buddies roommate for way to long in kerbal.

[@kittyn5222]

Why do you look familiar.

[@tekbox7909]

Same at least not for someone who has basically no clue why he does anything.

[@SecureGM]

Delta V is one of the most important parameters of your rocket/stage you have to read about. It will allow you to get some idea about expected performance, the only thing after is to account for gravity and atmospheric loses. In short it's the expected change of speed you can get. In vacuum, if you burn prograde or retrograde it's exact figure, but during launch some is "eaten" by drag (best to not go faster than 250-350 m/s in the low atmosphere), and a lot by gravity, the lower TWR they higher loses.

[@thetruecyrusplayz1256]

As a Kso player that has been playing for 5 years, I think I can give a word or two to help with your difficulties. First of all, You don't actually have to cut thrust when the apoapsis reaches 100km, you can actually cut it when it reaches over 80km(somewhere between 85 and 90km would do), because that's where (at least to my knowledge) Droo's atmosphere ends, So you can save a bit of fuel by doing that, but note that it will give you less wiggle room in terms of timing. Also, I believe that you can still use the direction controls in space, which would've helped you adjust your apoapsis and periapsis, to simplify it for now, Pointing *prograde* means accelerating in the direction of travel, i.e it raises your apoapsis when you're at periapsis, and vice versa at the apoapsis. Pointing *Retrograde* is the opposite, it lowers your apoapsis at periapsis and vice versa. Hope this helps( and reaches you)

[@gameefan]

Remember that you don't need to keep accelerating until you reach the desired firework explosion altitude. You only need your apoapsis to be that high. When your apoapsis is high enough you can cut the throttle and wait. This way you can save some money

[@Maurony]

Yeah, that's great and all until you realize he wad using solid fuel thrusters. 🫢

[@christianjaymoralde7504]

But the drag slowly pull it down so you have to give some allowance

[@9tr0n]

@@christianjaymoralde7504 your apoapsis is already at that height so it dosent matter

[@kovanovsky2233]

@@9tr0n As long as you're still in the atmosphere, the air drag would slow you down and lower the apoapsis slowly. The apoapsis number assumes no atmospheric drag.

[@ineedtogetoutmore1848]

I’m kinda surprised how quickly you got a hang of Apoapsis and Periapsis adjustment, good job man

[@altpanic6794]

Watching Scrap figure out orbital mechanics has been fun, I really hope he tries KSP2 soon.

[@krattfan03]

Man you figuring this out was beyond impressive and relieving. I got so excited every time you revealed that you knew what affected what when controlling your orbit. I've tried to teach my friends how to do all kinds of things in ksp, scrap mechanic, and trailmakers but they all seem to just rely on tutorials and help and they never figure stuff out on their own. It's so relieving seeing someone who can actually figure these things out. Incredible.

[@Plasma_Mobile]

You have to play KSP 2! It comes out today including high min PC specs and a great tutorial series for beginners. It's also way less complex doing a great job explaining basic orbital mechanics.

[@thetautvyduxs5242]

[@opanzerofthelake36]

all nighter paid off

[@stevepittman3770]

Damn, great job on figuring out the orbit thing! That's seriously one of the hardest things to wrap your head around in this kind of game and it's an absolutely required skill to go anywhere else. I feel like the game could definitely do with a better tutorial that explains the why as much as the how and when though. 22:50 - The reason it can't do the math for you is because those are ideal numbers that don't account for things like atmospheric drag or gravitational losses. The math that does account for those things is quite complex indeed, but you can use these numbers to estimate the capabilities of your rocket once you know some basic things like TWR>1 is required to launch and how much delta-v is required to get into a low orbit, etc.

[@DownundaThunda]

One thing I would recommend is that you check out Scott Manly's KSP Orbit Tutorial. It's similar enough that you should be able to transfer skills between KSP and Juno.

[@brandonsattizahn4443]

Learning to orbit is the steepest learning curve. Now that you have that down and you understand how to control your apoapsis and periapsis, everything else is just a matter of applying that knowledge. Want to transfer orbits to another celestial body? Just aim your apoapsis so that it intersects with the target's sphere of influence (the area where the gravity of the target starts pulling on you more than the earth, or in the case of other planets, the sun). Want to land on something? Just get into orbit around it and bring your periapsis down until it intersects. Obviously, there's still some details that will take some figuring out, such as optimal transfer windows and how to land safely without blowing up, but with how well you figured this out I have no doubt you'll be able to face any other challenges as well. I'm super excited for this series! Please keep it up!

[@Blaster_Unity_UB]

Congrats on figuring it all out! It's very complex, but still you did it! Tip: Watch the reference vid, and some other optional content on it, right before recording the next episode. It's surely help! Good luck 👍🏻

[@smarty265]

Actually this game is 6 years old.

[@Galactic-Spaceflight]

New editor's doing a really great job!

[@andreyemelyan5267]

You're really smart, ScrapMan, so proud of you. Here is some tips: don't do the final "10 degrees above horizon" - instead do 0 degrees. Also the major thing in "not falling from orbit in the beginning while burning" is get to orbit before you reach the apoapsis, but even if you get past it - you almost always can move it back, you just need to tilt higher, to make it move ahead of you. Simply explained by your own experience, just try to tilt slightly higher and lower (to horizon) looking at your trajectory, while burning after exiting the atmosphere.

[@invention64]

Pro grade is in the direction you are heading, and retro grade is against. You need to do a gravity turn before you can set your heading to prograde.

[@MechaNexus]

I recommend you do more Juno so you don't have to infodump yourself every week. It's such a great time watching you do rocket science. Maybe try sandbox and make a plane that's multitudes faster than the speed of sound.

[@thetautvyduxs5242]

Planes in this game are really hard to do properly.

[@xmertrix]

@@thetautvyduxs5242 Not really. Have CoM in front of CoL both full and empty fuel tank. Have sufficient lift and make wings thicker so they don't snap easily. Reduce operating angles of control surfaces. Good to go. Also to save cost you can make mini planes with smallest possible size.

[@tropicalvikingcreations]

Great work Scrapman! Well done! Typically earth ref based planets tend to have their atmospheric drag end above 80k. Some have it at 80,75,70 so above 80k is usually relatively safe for the sideways manoeuvres. You got the hang of increasing AP and PA pretty well, so that's nice. Just a note ahead of time is usually when you have to do a retro burn for landing or entering a new orbit you usually want to be ready to do your burns ahead of time so you can adjust in space games. The delta V in space will tell you how much difference in velocity you can make, so ... If you know your distance to target position, you can start a slow burn increasing to a full burn plus half before that or give yourself at roughly a quarter before that distance so you can take time and kill your velocity and make sure you leave yourself some fuel so you can come down softly. Note this method usually requires adjusting throttle and not just full power into a suicide burn touch down. Yes the actual name for the maneuver. Idk if this is too complicated an explanation or not but game will likely teach you when the time comes. What I suggested just gives you more time to be delicate but isn't exactly necessary.

[@coolestmaid]

I want to see you play this again! It's so fun!

[@andreyemelyan5267]

More friendly tips! Major thing in getting to orbit is get out of atmosphere and have enough horizontal speed to not fall back, that's all, seriously! All those "get 70 degrees, lock prograde, etc." is to save more fuel, but it's nothing more then 50% of savings. In your case with all these overburns you don't save anything, actually.

[@mbrennecke]

We certainly, absolutely, positively need more Juno!! Great Content!

[@tomsterbg8130]

This game is both amazing for the knowledgeable people and really low quality in certain spots. I love how you can get better with the build system and optimize a rocket a lot by making it cost less and go further and optimize your orbiting trajectory etc etc. Once you get it it's a great game

[@1nicube]

i remember playong kerbal space program when it released and the tutorial was so easy to understand. Maybe try the kerbal space programs tutoral to understand what to do!

[@oblivion098]

Really liking the new style editing. 👌 Feels much more professional and entertaining..

[@zacha8869]

Prograde just means to accelerate in the direction of velocity. Earth's gravity is pulling you in that arc. Retrograde means to accelerate Against current velocity. Basically, to get to orbit, you need to go up, then go tangentially along Earth's curvature until your predicted path makes a circle around earth.

[@zacha8869]

Also, those other pips are to accelerate towards/away from gravity. Then tangent and reverse tangent.

[@mynameisntdave317]

I really like how there the the explanations on how to properly perform these things while scrap man shows how to do the wrong things, bonus points for the editor!

[@mattymerr701]

With the tutorial, it was telling you to cut off the thrust when the info window on the right had the apoapsis height at something like 80km Then you are waiting to get to that point to then thrust to circularise since it is most efficient to thrust at the apo- or periapsis Edit: you learnt it pretty well rewatching your own vid. That's awesome! :D

[@BOMBO-]

the speed at which you are learning is genuinely astonishing

[@Mau_DelS]

Very nice series, i liked so much how you figure it out, and don't know if someone else noticed but you had the ability to do fourth stages from the start (it also appeared when you changed the motor ) as at the end you unlocked the fifth stage :)

[@masterdragon2698]

To easily get into orbit, you could try having a shallower trajectory earlier because in your early launches, you had a lot of vertical velocity but not a lot of horizontal velocity. To have a stable orbit, you need to have a high horizontal velocity. Hope this helps you more reliably get into orbit

[@zenorbi]

I cannot tell you how happy I felt as you succeeded into figuring out the basics of orbital mechanics. Once you got into orbit something clicked for you and you immediately knew how to manipulate your orbit.

[@SideswipeMedia]

Great video. This series is my favorite you're doing right now. I do miss your zeepkist tracks tho.

[@andreyemelyan5267]

Here is more friendly tips! To get hang of getting into the orbit, you can try accelerating straight up until apoapsis makes it to 100km and then turn flat heading the horizon once you left the atmosphere and start accelerating sideways until you get to your orbit. The time above atmosphere's edge should be enough to get to orbit, if not - try heading 10 degrees instead of flat to the horizon.

[@wdtgames8834]

I like that his editor is telling us the correct answer to what scrapman says

[@pjamestx]

Great job sticking with this, that looked difficult!

[@kingkaktus284]

Absolute genius. also trying to lean this game and would never think of doing this

[@theorensummoner43]

While your in-between your apoapsis and periapsis, you can point your craft perpendicular to your trajectory (towards or away from the planet) to move your orbit kind of sideways (towards your apoapsis or periapsis). It might take a minute to understand, but I hope it helps.

[@-neutronyblack-2133]

I love your juno videos! but as a long ksp player , i think this game is too complicated to play as the first space game in kerbal , you dont have to deal with nozzle size , nozzle pressure and .... i suggest you also play kerbal so you learn the basics easier also , you can also watch kerbal tutorials , the concepts of orbits and how to achive them is pretty much the same in both games

[@frogsecretaryofswamp452]

try unlocking fairings, those helps alot for transporting things to orbit

[@joschuamccurley5647]

You gotta wait until you reach the apoapsis, then turn prograde and fire the engines. If you stop your engines when the apoapsis reaches the preferred height, then you wait until you reach it, that is when you extend the periapsis.

[@rishanraaj7367]

Tip- play the game outside the campaign mode it's fun to build massive rockets without worrying about price and do you know what's also fun? simply adding 10-30 thrusters to a simple cone shaped fuel tank and see it jot up into the sky like a bullet.

Scrapman, if the Periapsis > 80km it means Greater than 80km becuase the “>” symbol means greater than if it is the “

[@reinholdadam711]

You don't have to get the apoapsis to a certain degree, that's just a standard setting for getting you there. An easier way to get what you want is to get that to 88 then increase the pariapsis to 90 or wherever you want it

[@mattymerr701]

You can use your "time to apoapsis" number to know when to thrust. About 10 to 20 seconds is good. Also thrusting prograde is the most efficient. You only need to thrust above prograde if you want to inefficiently get your apoapsis higher to make up for not gaining velocity fast enough

[@mattymerr701]

The tutorial gives you a recipe that works, but it isn't a general or super efficient recipe. It's up there though!

[@noelradhakrishnan4423]

25:45: Hey, press that launch button right below, you might find some tutorials

[@grook8958]

Here is a tip: Lock Prograde at Apoapsis = Increases Periapsis Lock Prograde at Periapsis = Increases Apoapsis Lock Retrograde at Apoapsis = Decreases Periapsis Lock Retrograde at Periapsis = Decreases Apoapsis (Ofc you need to burn for it to happen)

[@marekvojta9648]

This is so painfull😅 Well at first there are no orbit and non-orbit motors there are atmosferic motors and vacum motors (simplyfied) so the orbit motor will work just fine when you enter space even in suborbit flight. Orbit making: You don't want to have the spike while trying to make an orbit (if you do the spike it means you have wasted fuel to get yourself so high) in KSP (don't know how there) is first stable orbit (circle) at about 80 km above ground. So you wanna ideally burn at upper atmosfere more to the side to make it more round (and you also may lower your thrust because to have same speed you need les fuel in higher atmosfere). hopefully this will help you. Anyway great video

Create an ascent guidance script in the scratch editor. Super simple to setup. It will do everything you're doing manually for the gravity turn on it's own. on start lock heading to Current wait until altitude ASL >= 5000 set craft Pitch to 85* wait until altitude ASL >= 7000 set craft Pitch to 80* ... repeat a few times for granularity ... wait until altitude ASL >= 20000 set craft pitch to 45* wait until orbit Apoapsis >= 50000 set craft pitch to 25* wait until orbit Apoapsis >= 60000 set craft pitch to 15* wait until orbit Apoapsis >= 70000 set craft pitch to 5*

[@TJ-dh2sr]

Heading perfectly east has to do something with the earth's rotation: The earth rotates around itself in 24h, so a point on the equator travels with around 1600 km/h to the east just by the earth's rotation. If you then decide to travel to the east you have an initial velocity of 1600 km/h which you do not need to use any fuel for. Would you travel to the west, then you first have to use fuel to counter the earths rotation and then an equal amount to gain this speed in the opposite direction. This way you would need to acellerate for additional 3200 km/h.

[@TJ-dh2sr]

Additional Information: That's also the reason why all space ports are as close to the equator as possible. You want to have an initial velocity as high as possible and since the earth diameter is the biggest at the equator, you have the most distance traveled each day by the earth's rotation and so you have the most initial velocity.

hello Scrapman I like the background behind you

[@sprained5]

He ScrapMan, I heard you wonder for a way to calculate the final height of stages several times now and if you want to use it I have a formula for you to approximate the height of a stage. The true height will be a bit higher as the full weight decreases and the atmosphere changes but these formulas become significantly more difficult if you want to factor these changes in and it might be dependent on the parts you are using. The numbers used here can be found in the staging analysis. Final position #1(numbers represent stages) = position #0 +burn time #1 * speed #0 + Delta V #1 /2 *Burn time #1 ^2 Final Velocity #1 = burn time #1 * Delta V #1 Then for the next stage Final position #2(numbers represent stages) = position #1 +burn time #2 * speed #1 + Delta V #2 /2 *Burn time #2 ^2 Final Velocity #2 = burn time #2 * Delta V #2 and simply keep increasing the stage numbers for every consecutive stage. If you feel like optimizing in the next video you can use this for approximations. And I must say you have a great way of approaching problems.
