Gemini Campaign Face 2 face REQUEST TARGET BURN

[clever oxide]

Hi in the Gemini Campaign Face 2 face i am asked to do a REQUEST TARGET BURN, but the radio button is not available was it replace by the RNDZ?
Thank you

[rustic stream]

It was, just whack RNDZ and you'll get the burn

[clever oxide]

Thanks tried it and still didn't get to the target so means I mess up further at least it pressed the right button 😄

[frail bay]

Gave +1 flight-hours to @rustic stream

[rustic stream]

It's very difficult so keep trying!

[clever oxide]

Yep just will try again tomorrow

As I need every time to restart from the ground

[rustic stream]

You can go into the pause menu and make a save state but that tends to screw with the dialogue

[clever oxide]

I will try also too look up some videos on how to understand the radar. I saw there is one for the Agena in the official YouTube channel must be the same logic

[rustic stream]

It is the same, just you can't dock with another Gemini and the encoder stuff he talks about only works with Agena

[clever oxide]

Yep that part I had guessed. Thanks once again 🙂

[frail bay]

Gave +1 flight-hours to @rustic stream

[clever oxide]

And yes it's the hardest mission so far

[rustic stream]

It gets harder 😂 once you see Apollo you'll realize that as hard as Gemini was it's a piece of cake in comparison

[clever oxide]

Any chance to organize a live session to guide some time as there no mocr for Gemini

Obviously not now 🙂

[rustic stream]

Possibly

In capsule multiplayer would be great for Gemini as someone experienced could watch over the shoulder of someone else and teach them, though I guess a stream works too

[rustic stream]

What issue were you running into?

[clever oxide]

That would be ideal

[clever oxide]

Honestly I think I get confused after the second rendez-vous burn or burn II in the checklist

[rustic stream]

With the RNDZ computer? A lot of people seem to get confused with that

[clever oxide]

Yep

[rustic stream]

It is somewhat difficult to understand but in essence the numbers show you how far off from being docked in each axis, distance wise

So your goal is to null the IVIs using translation, but left and right are currently reversed so it's a bit weird

[clever oxide]

Is the reversal a bug?

[rustic stream]

Yeah

[clever oxide]

Also I have trouble figuring out in what direction the target is

Using the FDAI

[rustic stream]

Have you set it to radar mode?

And in att mode for the second switch?

If so then just go towards the needles and you should be pointing towards it

[clever oxide]

I had set it that way

But also the ivi where going crazy no matter where I was pointing too

[rustic stream]

That's weird

They do change pretty quickly but they shouldn't be wildly swinging unless you pitch or yaw

[clever oxide]

Thanks for the tips I am calling it a night and will try again tomorrow

[rustic stream]

No problem!

[clever oxide]

probably missed somethign again

[rustic stream]

If you are far away from it you can't just translate towards it, forgot to mention that

It also looks like your orbital plane is not right

A trick I've learned is to point SEF or BEF (depending on whether the target is ahead of or behind you in your orbit respectively) and then burn AFT until an apside changes by 5 nmi. Initially you will drift away but then you'll get closer because of orbital mechanics. Then eventually you'll be under or over (as the pros say: on the R-bar) the target, and you brake then point at it and continue hopefully from a much closer starting point.

[clever oxide]

At the start the orbital plane was aligned and some how I ended going underneath it and overshooting it. Must have been blind cause I never saw it in front of me and never got closer than 30k feet.

[rustic stream]

Yeah until you get within about 10k feet you can't just burn at the thing or you'll end up in an eccentric orbit and under or over it.

[clever oxide]

OK so that's what happened, but then how do I get closer to it before 10k?

[rustic stream]

Try the strategy I talked about above

[clever oxide]

Burn aft?

[rustic stream]

Yeah

Then orbital mechanics will cause you to get closer

[clever oxide]

What do you mean "apside changes by 5nmi"?

[rustic stream]

Either apoapsis or periapsis, apside is the general term

If you're pointing SEF and near apogee thrust until your perigee decreases 5nmi, if pointing BEF near apogee thrust until your perigee increases 5nmi or increases to you current apoapsis

[clever oxide]

OK

[rustic stream]

I have to leave now but try it and it should help!

[clever oxide]

Since the target started behind me I should had pointer bef and thrust aft to decrease by 5 nmi the pe

[clever oxide]

Thanks once again

[frail bay]

Gave +1 flight-hours to @rustic stream

[clever oxide]

Have a good evening or whatever its for you

[rustic stream]

Evening and thank you!

[clever oxide]

and again failed

[wicked ruin]

Yeah it's hard. Think it took me 4-5 tries until it clicked. Also one thing that may help is turning on realistic burns. I think it strangely helped me, but I'm not sure as I also turned that on before doing the mission where it finally clicked for me. I would get on to see what the difference feels like, if any, but I am at a pharmacy atm. Also sick and in a bit of pain so may not be feeling well enough after I get back, lol. Also after watching a video, though I don't remember what exact one it is off the top of my head. I can try to find it later.

Not sure if it's the best method(probably not tbh), but what I do is after the circulatization burn, the rdvz burn, and second circularization burn is wait for the rndvz program to load (and radar to warm up if not already). Once loaded face the agena (can face while waiting too) and then thrust towards it until I'm approaching at ~100-150ft/s while keeping the y and x-axis on the IVIs as stable as possible (not necessarily 0, but close until I'm close enough to slow down and start aligning with the agena proper). The x axis is flipped, which definitely throws me off occasionally since you have to thrust the opposite direction that you think you do. Start slowing down just before 10K ft or you might fly past it.

[clever oxide]

Thanks for the advice, will check that option, unfortunately unlike the egena that second mercury is small and I can't see it. Also I some how manage to overshoot it every time.

[frail bay]

Gave +1 flight-hours to @wicked ruin

[rustic stream]

it doesn’t have lights unlike agena so it can be hard to see

[clever oxide]

OK so I am not completely blind then 😄

[wicked ruin]

Ye I forgot the specifics was face to face when replying. Have to rely solely on the instruments for that.

However my overall approach is the same. Just have to watch the instrument panel when turning to face instead of the flashing lights.

[clever oxide]

Cheers thanks

[clever oxide]

@wicked ruin hi

[wicked ruin]

Hello

[clever oxide]

I am about to retry the mission if you are up to watch or assist 🙂

In about 15 minutes

This time with realistic burns

[wicked ruin]

Normally I would be, but I am unfortunately still recovering from whatever sickness I have (I have an autoimmune disease, so it can take me longer than normal to get over a simple cold). This is the video that helped it click for me, as well https://youtu.be/dUmoRAIKAzY

It's the entire mission, so you may want to skip ahead.

[clever oxide]

Oh sorry to hear that hope you recover.

Thanks for finding the video

[clever oxide]

this is it

[clever oxide]

and failed

never got closer than 10k feet

[wicked ruin]

In the image you are already moving away. Thrust until that middle needle (the second largest one) is around 100-150(tho I'd recommend not faster than 100ft/sec so you can correct for mistakes easier). Afterwards just keep the X/Y direction on the IVIs stable as you approach. If you see the FWD/AFT IVI start decreasing start thrusting aft immediately if you haven't started slowing down by that point. Then I would just be on a nice slow approach around 10ft/sec and just gradually slow down as you get closer.

[clever oxide]

i think my mistake was thrust fwd to much

and then it was to late to correct

[wicked ruin]

Yeah if you wanna go wild you can thrust towards it fast, but you have to adjust accordingly. I'd recommend not more than 100ft/sec until you start getting the hang of it. You can definitely go slower if you have the patience for it, as well.

[clever oxide]

will need to try again thats all 🙂

[wicked ruin]

Sounds like you're getting close, tho! It's so satisfying when you finally complete it lol.

[clever oxide]

one question do i need to keep pressing fwd or once i reach 100 i can just stop?

[rustic stream]

do not keep pressing forward or you will fly by the target at ludicrous speeds, don't forget you need to slow down later

[clever oxide]

Ok i see the other capsule here we comp is loading RNDZ

[rustic stream]

good luck!

[clever oxide]

thanks

here is the situation

[clever oxide]

i see it but

i am already getting away from it

while i was still thrusting forward

[wicked ruin]

I would say I also keep the IVIs <20 in both x and y directions. I'm not sure if that's exactly what it is, but should make it more difficult to fly over it. When you do all of your rndz and circ burns is the target close behind you?

I'd also like to get on to see, but unfortunately I started feeling worse yesterday and today about to head to an urgent care as my thermometer (tho I have no way of validating how accurate it is as I have only one) keeps reading that my body temp is 94⁰, which is uhhh if true.

[clever oxide]

Health first get better and we can organize something.
To answer your question yes after the rndz and orbit circulation burn I end up about 20k feet in front of it so yes it's behind me.

[wicked ruin]

Yeah, I've been sick for 5 days now and am getting stir crazy lol. Missing all of the new FFXIV stuff, as well 😩

[clever oxide]

Anyway wishing you to get well soon 🙂

[wicked ruin]

Thanks. Currently waiting on test results to rule out things like strep, covid, flu, and rsv. I really hope I don't have covid (But I did do a self test for this that returned negative) or RSV as those can be really dangerous for me with my autoimmune disease.

hello ive read through this post too see if it would make sense but i still cannot understand the IVIs in rendevous or how to move them around. in the manual it says they are a 'difference in velocity/position relative to the target' but i dont see how that works in game. im super super familiar with ksp rendevous and docking so i understand the ideas behind it but i cant understand where to get the info i want and how to apply it yet

my 3 main questions are:
-how can my relative velocity suddenly become 0 if i look straight at my target?
-how does translating with oams change the numbers (sometimes it speeds up then slows down and ive done nothing different)
-what do the green lights on the IVI mean in rendevous mode? where the target is relative to my location? where i need to burn?

thanks for any replies!

[rustic stream]

the IVIs are quite strange. The up/down/left/right is keyed to the radar and will indicate 0 if you are pointing straight at the target. Forward/aft is distance. Your goal is to at circ show up about 30kft from the target, and then get closer using a combination of orbital mechanics and the IVIs.

Left/right is also reversed (a bug) meaning if there is a value right you need to thrust left. For up/down the opposite is true, if there is a value up you need to thrust up.

[steady moss]

ok that helps a ton with the reversed left/right axis. so the green is where i need to go then? (except for X axis, where its the opposite)

[rustic stream]

yeah exactly

what I have heard is you point BEF or SEF (whichever way the target is closest to) then translate to null those

[steady moss]

ok thats big. thanks! that kinda works out i guess bc my controls for up down are inverted (preference) so i just need to go opposite anyway. il try that later, appreciate it. hopefully it clicks for me

[rustic stream]

I hope it does!

[steady moss]

i think its clicked for me! appreciate it a ton!

[rustic stream]

Great!

Hello, I am also having much troubles. I tried 10 times with no success. What I don't understand is how to aim for the target right after the 2nd rendezvous burn. I always come up in a good position, but the orbits at this time are not perfectly aligned so I have about 20minutes before they start to diverge enough so that only another rendezvous burn could help. So right after the 2nd burn, while I wait for the computer program to load, should I try to stabilize the orbits? I tried using orbital mechanics, no luck, even with a tiny but the orbits diverge. If I wait for the computer and the IVI's , they start with the fwd/aft indicator at 999 and the other changing wildly, so I don't understand how to use them in this case. If only the academy or the guide covered this..

[tight haven]

Eventually I solved it with a combination of advice from this and other Discord discussions, and my prior knowledge of orbital mechanics.📚
The biggest issue was the unprecise burns, either late because not 50/50 or too high eccentricity while the mission scripting allowed it as a circular orbit. I trusted too much IVI's and mission script, should have used mostly the computer and cores 99 and 98 .Then I used the apogee slight raise/lower to correct most of the orbit phase difference until about 10k, then learned to zero the IVIs slowly, knowing also about the inversion bug. I wonder why it has not been corrected yet.🧐
