help getting orbit, a second time.

[Spricigo]

 

oops, my bad...was still thinking about the surface rescue idea.

 

Notice that the stayputnik don't have any SAS and without a kerbal on board you need a link to KSC for control.  Still, not that prevent you from being suscefull.

Im  using  the  probodobodyne okto.

I  read  the  rendezvous guide  you  posted, and  the  game  isn't  telling  me  relative  inclination like  the  guide  says  it  should

Active vessel and target vessel need to be in the same SoI.

Can also be displayed by MJ

o.....k, so ive almost matched orbits but i have a couple problems.

i have no idea where relative inclination is, and we are going in opposite directions. the unmaned ship is the one on the right, and jeb is lower left.

please help me bring jeb home.

Ok, look for the AN and DN markings, those are the points where the orbits crosses. If you hover the mouse over this marking it will show you the inclination.

 

Inclination change are a lot cheaper when your speed is low, thus at higher heights. So the best way to invert the direction of the orbit (change of inclination by 180º) is to raise the orbit up to the limit of the SoI, coast to apoapis and revert your orbit there (point retrograde, set SAS to hold orientation and burn), after reverting the orbit cost again to periapsis and lower the apoapsis.

Don't worry, you still have enough deltaV available.

[Spricigo]

BTW you go stranded on the Mun and now ended in a orbit that is reverse of the intended. congratulation, you are not a true kerbal player until you do those things.

so, i want to raise my ap until its almost an escape trajectory, coast till i get their then burn retrograde until my orbit reverses?

that is it.

You can do at lower heigh if your deltaV budget is enough. But let's be in the safe side, we still have a rendezvous to do.

im still confused about the relative inclination thing.

is it the degrees that appear below the dn and an?

yes

OK, we  are  in  nearly  identical  orbits  but  on  opposite  sides  of  the  mun.

How  do  I  slow  down  or  speed  up  for  rendezvous? Retrograde  and  progreade  just  mess  up  my  orbit

If you apoapsis is still high from the reversal manoeuvre you'll be orbiting much slower than the other ship. Get your periapsis to touch the target orbit at one point and once you've passed the closest approach intercept marker at that point you can burn retrograde to wind the target position marker around until it gets you a close intercept.

ah, thats enough frustration for tonight.

i finally got my intersect, and target position at intersect within 5km, i orbit till closest approach, i switch to the jeb pod, get out and get sucked into the moons gravity while trying to eva to the other ship.

i try again from a quicksave and right before going eva i realize valentina is in the rescue ship, has been the whole time.

well theirs two hours gone, will try again tommorow.

[putnamto]

im just going to scrap this whole mission, kill jeb and wait for him to respawn, theirs just no way out of this situation or im just to stupid to figure it out.

a bunch of questions before i completely give up on this game.

changing inclination, i set the manuever over the dn or the an, i move normal or anti normal until an or dn gets to .03, seeing as its impossible to get 0, once i go past .03 it just jumps to .03 and starts climbing again. 
when setting a node why does the game tell you what your inclination will be but not what it currently is anymore, and no matter how close i get on the burn time after clearing the node my an or dn has jumped to 1.5 even though the node told me it would go to 0.3(0.0 does not exist obviously)

i followed the guide for rendevous that was given to me earlier, and the intercept distance is never going to be under 5km, it gets down to 15 then jumps way out the other direction.

if i eva jeb from his coffin shortly after he gets pulled into mun(i can tell this because he loses his target and the screen orientation changes) how can i prevent this.

Well, do something else for a while and when you feel more prepared try rendezvous again. It become easy after you figure out a few things that are not evident at first, just that those insights sometimes takes time. 

Also, I think that necrobones can do a better job explaining it then I did:

 

[putnamto]

yeah i have a tendancy to get extremely frustrated, sorry.

about the jeb thing though, his pod is locked in orbit with no fuel, and as soon as he lets go of his pod he loses target.

just got done watching that video, thank you, it definately cleared alot of things up, compairing that to what i was doing is like trying to wear your shoes on your hands

Edited January 28, 2018 by putnamto

Jeb loses target on leaving his pod because the rescue ship is too far away.  If he can't see it, he can't target it.  A Kerbal on EVA can target a vessel, but they have to be close together (I've generally done it at distances of a fraction of a km).  So, you need to get a closer rendezvous (less separation, less relative velocity) before Jeb makes his jump.

[putnamto]

uninstalling, thank you guys for trying to help but im just to loveing stupid to play this excrements.

i have never wasted so much time and frustration on a single loveing video game in my life.

i get within .7km of the target our orbits match, ive followed the loveing guides and no matter what i loveing do their is absolutely no way to match target speed it gets down to 2.5 m/s then the number starts rising again.

sorry for wasting your time and your message board space love this.

lol at the censor

HE  GOT  THE  loveING  SHIP, JEBS  ON  BOARD  WITH  ALL  THE  SCIENCE!!!

 

He  only  has 207 dv  left  though

[putnamto]

and he forgot half the science, and i had to cheat him back

Is that the feeling of just doing something that seemed impossible just a few moment ago?

Congratulations.  You changed "impossible" to "possible but hard". Keep practicing and it wil become "easy" eventualy even "second nature".

Let's see.

You managed to do a rendezvous and an EVA transfer. It took some resources (funds, time, effort). But you still don't have enough deltaV to come back to kerbin.

The issue is that you used too much fuel in the rendezvous, overshoting and overorrecting. A more efficient rendezvous would left enough for the return to kerbin. Do you think you can do it?

If a better rendezvous is not possible you can still use that fuel to raise your orbit around the Mun and make a new rendezvous there. The advantage is that the rescue ship will not  need to waste fuel going so deep in Mun's gravity wheel.

 

Finaly, notice that Jeb is fine. Just look at his face, he is enjoying it all. You can let him floating around a lot of time and he will still be fine. Meanwhile you need to asign Val, Bill and Bob to missiins too, or they will start to complain about it.

A further advantage to a higher orbit is less deviation during approach/docking (whichever), and you're likely going to be in darkness for less of the total orbit as well.

yes, this would probably have been alot easier if i wasnt trying to dock at 5000km off of mun

[putnamto]

why does my dv change after reverting a flight back to assembly?

ill have a total of over 6k dv vaccumn then i test launch, forget the struts and watch it turn into sphagetti, reload and now my dv says 4k vaccumn

and any tips for liquid fuel booster stages attached to the sides of the rocket? the editor does not like those, whenever i try to add a fuel can on top of the stack it constantly tries to lay it horizontally.

[Spricigo]

about deltaV change: Are you sure nothing changed in the rocket? Staging would be my bet.

 

sphagetti: If you go to setting and enable [allow advanced tweakable] you will have a some extra options accessible by right-click a part. among it the option for autostruts and rigid  atachment. You can use this to make your rocket more rigid, the caveat is that it will be more brittle too. Also autostrut to heaviest/root part cause the risk of a rapid unplanned disassemble if the hevviest/root part change.
