I have played KSP for 700+ hours, all that time I could not get a single rendezvous, but you got me to my first. You have a like button slaughtered and a sub : D
I did a triple rescue last night in low Kerbin orbit. 2 of them were so close I didn't bother with more than rescuing the first of them, then just powering over to the next using the nav-ball to line up. But... ORBIT PHASING!!!!! It would have worked getting to the far one and coming back in!!! I'll be trying this from now on!!!!!
@@MikeAben True. But these craft were right at 20K from each other. I rescued the slightly lower one first, then sped on to the slightly higher and further ahead one, while powering slightly off target toward radial in. It took a few slow-downs and corrections, but I built my craft with plenty of fuel. A single tank and a poodle and the RCS system and I had some fuel left when I cut the last stage loose to reenter.
At first glance a way to optimize this could be to launch at 1 of the low orbit kerbals first. With practice this can be done pretty accuratly with just some minor changes while in orbit. Now u got 1 so u head out for the high orbit rescue next and after that u use the orbit Rendezvous Trick for the last kerbal in low orbit and finaly your deorbital burn. This way u dont waste any fuel betwinn the 2nd and 3rd rescue. The way u did it in the video u needed to spend fuel betwinn the 2nd and 3rd rescue to slow back down again to match it´s speed. Maybe i am overthinking this but it looked like your way did 1 burn that could have been avoided if were talking fully optimization. The only downside i can think of is the inclination diffrence as u head out for rescue 2 in high orbit and then back down again before rescue 3 but becouse u are so far out the Delta-V required to fix it should be tiny. The mistake i think u did was that u needed 4 burns before the first rescue. Launch, Orbit, 1st rescue encounter, 1st rescue match speed. The best way from my pov would be to launch into the first rescue in low orbit so that way your orbital burn could also be used as an encounter burn assuming your launch timing was close enough that when u hit orbit u end up just ahead of the target and u could do the same technique u did for your 2nd rescue encounter. Now u have only 3 burns before first rescue. launch, Orbit/1st encounter, 1st rescue match speed. So instead of 9 total burns including deorbit u now have 8 total burns from launch to landing. All of this ofc depends on a fairly tight launch window so that u can use the orbital burn as a 1st encounter burn. But if we are talking optimization i think this would be more fuel efficent. What do u think.
I'm not sure it's right to say the best place to do your burn is half-way between where you are and where you want to be if where you are initially is arbitrary; that would imply that when you got to the mid-point you should re-plan for your burn for your new mid-point ad-infinitum. Isn't it something more like you want to be roughly a quarter revolution away for inclination changes and half a revolution for height changes?
That is a more general way to say it, though typically your encounter will be half an orbit from your transfer burn, so it will usually amount to the same thing.
Instead of saying "slow down" and "speed up", what you actually mean is that burning prograde makes your orbit/period longer, burning retrograde makes it shorter. Because in the moment of the burn of course you are speeding up when you burn prograde for example, but you also make the way the craft has to travel to come back to that point longer. So if your target is in front of you you want to make your orbit shorter to catch up to it, if it's behind you you want to make your period longer to fall behind.
It's more like it slows you down or speeds you up relative to the target. Saying it flat out without the mention of the reference frame makes it sound way more confusing and weird than it really is
If you mean during my first rendezvous, I'm burning retrograde relative to the target, but that's prograde relative to Kerbin. If we keep Kerbin as a reference it all makes sense. Relative to Kerbin, my velocity is less than my target's, so the target is catching up to me. To rendezvous, I need to match its velocity, which means burning away from it (retrograde relative to target). However, this is increasing my speed relative to Kerbin, so in that frame I'm burning prograde.
@@MikeAben love the fact that you reply even to old vids you deserve a pay raise and your the only thing that kept KSP 2 alive for me cause I woulda been quit without you they need to pay you too
@mike, I had a high above kerbin rescue, but the orbit was going retro around kerbin and a huge inclination. What I did was got a non crewed module out to his orbit so I could take control of him, then I used his jet pack to get his periapsis down near the planet. Now iv just got to work out a way to get him, but I guess the only way will be to launch at 180 degrees with alot of DV ? Any tips?
Definitely launch into a parking orbit with the same inclination has the target. It sounds like the target orbit is pretty eccentric. If so raise your orbit to touch the periapsis of the target. Put a maneuver node there and use it to get your rendezvous.
@@_RandomPea You want to be going in the same direction. I just found this old tutorial that I hope will help. ruclips.net/video/eaflQT5yxmc/видео.html
@@MikeAben well I'm getting a tonne of practice here :) his relative speed is around 2k at periapsis, and slows to 450 at apoapsis, pretty much halfway to the mun. So I was trying to be clever and get out there and in theory I would need 450 to slow at intercept. Then what another 450 to get up to speed with him, so I just need just over 1k deltav to be safe. handbrake turn! Gotta be possible??!

Are you a Ranger's fan?
I knew all the theory and techniques, but never put everything together in this application. I knew it was possible and here it is. Bravo sir.
Thanks. I figured it was a good opportunity for all this kind of stuff which is all so very useful.
biggest prob with you is you make it look to easy making me LOL Thanks VERY much
"how do all these kerbals end up in these precarious situations?"... well, if a person is doing your flight planning, do NOT eat his lunch.
why is burfurt in a perfectly circular high earth oribit
@@SALTrobot Burfurt is short for burnt further. Always burns out his fuel way beyond the others.
So much to learn in this game. So many little problems to solve. I’m totally addicted haha
I've been binging so many of your videos lately... by far the best educational KSP youtuber out there, keep it up :)
Are you bad at the game because you had to rescue them or are you good because you can do the rescue
There's clearly a rival space agency that's really bad at what they do. That's okay. We're poaching their astronauts.

mikeksp,pretty sure everybody,including you,has ran into problems in kerbal.dont be a dick
@@Shiftry87 Knowing how schizo kerbals are, it could have decoupled, or it had a module below it
@@Shiftry87 vessel was destroyed by the impact with an asteroid or another vessel. Or maybe faulty decoupler(or stupid crew member) decoupled the compartment at the wrong time.
Very interesting; I generally go coplanar and then go into a circular orbit slightly larger than the passive vessel. This technique does look simpler.
You just have to watch that you don't burn too much and don't have enough fuel to match velocities.
Thanks so much for these videos, Just rescued Valentina from a failed mun return with the help of these rendezvous guides.

You can just copy the install to somewhere else and keep the mods on one install, and remove them from another

Unless the two objects are very close (like several kilometers), powering straight to the object can use a shocking amount of fuel.

Maybe they should step letting scientists fly solo!
How are you burning retrograde and still increasing the size of your orbit?

question did you circularize your orbit before you picked up the first kerbal?
Yes.

@@_RandomPea The closer your orbit is to the target orbit, the lower your encounter velocity will be, if that helps.
I always get my rendezvous down to below 2km. Anything larger takes too long to cover the remaining distance. Usually I go to 0.1km
gyus, how can i make intersect point on a light side of the Planet?
My hunch for how they ended up there is that they accidentally pressed space and decoupled their engines

- What? How? I prepared this vessel for everything
