Sounds like a very good idea.  Still using Kerbalism?

Of course. It still works, even though it hasn't been updated for v1.1.3. Kerbalism all the way. (I still don't know all its tricks; I just cram everything with shields at max. capacity LOL)

[NotAgain]

@lajoswinkler Do you use RemoteTech? And if so, where do you get antennas with that kind of range?

[lajoswinkler]

@NotAgain I use only few of its parts for looks, such as the big white dish it has. I've deleted everything else and thus that mod has no function besides aesthetics. I don't want to go into the hassle of all that, Kerbalism is hard enough.

Kaos 3 has launched.

Spoiler

 

Getting rid of Thumpers.

Spoiler

 

Climbing through stratosphere.

Spoiler

 

Jettisoning the first stage.

Spoiler

 

Second stage is kicking in.

Spoiler

 

Kaos 3 has established a direct link to the Kerbal Space Center and is waiting for further instructions in a circular, equatorial orbit.

Spoiler

 

Second stage will be able to achieve second cosmic speed, correct the inclination and accelerate the craft so that it will probably be able to reach at least Jool. Ion engine will then carry on.

[lajoswinkler]

Second stage fires again, giving the probe around 1 km/s extra velocity.

Spoiler

 

Kaos 3 jettisons the second stage, deploys its instruments and starts to fire its ion engine.

Spoiler

 

With only around 20 m/s left, the craft has now reached third cosmic speed and will leave Kerbol forever. The plan is to do a flyby of Plock (and possibly Karen, too, if it gets into a suitable position) as low as possible and will be corrected on the way.

Spoiler

 

The probe is on its way, its systems are working. Hibernation will occur very soon.

Spoiler

120 days in, Kaos 3 is crossing the orbit of Duna.

 

Meanwhile at the KSC, Kron 6 is being prototyped. I think we'll go with 4, instead of 3 engines this time. Plock is a really tiny planetary body and we need some more serious force here.

 

 

I've used the parts from what seems to be a revival of Active Heat Management. (https://spacedock.info/mod/790/Active Heat Management System) I expect there will be a lot more changes here, but this is the general look, with the centrifuge and all.

@lajoswinkler

Will you use the Moons of Eeloo mod? It adds a Pluto-alike moon system to Eeloo in the stock game, but with a little giggery-pokery (which IS supported by the creator) the moons can be placed in orbit of Plock. All you have to do is edit less than 20 characters of the configs. It also adds an atmosphere to Eeloo.

I like the idea, but I'm using both OPM and Sigma Binary so... what happens in that case?

I'm using them too, and it seems to work perfectly. To change the mod to support OPM, go to GameData/XPC/EelooAlt/PlanetConfigs/ and delete Alu. Then go into the config files of Beros and Kyx and change referenceBody (under orbit) to Plock. This edit is supported by the maker, who gave me the original instructions. If you don't want an atmosphere to be added to Eeloo, delete the Eeloo config too.

But it has a roughly 600,000km SOI.

How are the Kron ships powered? Apart from the solar arrays on the earlier missions, I'm not seeing any power-generation apparatus.

Thanks. Will try because Beros and Kyx seem as an interesting addition.

Indeed, there is a lot of time to brake, but I'm gonna go hyperbolic. Going to Plock using Hohman transfer would be insanity.

Almost all Kron ships have had a NFE fission reactor.

It's time for a new signature, no? Your series was one of (if no the) things that make me start playing again KSP

EDIT: I miss kerty, could you consider trying to get back again?

Well I say, I totally forgot about the signature.  Thanks for reminding me!

 

I'm working on getting Kerty back, yes.

I did some tweaks of the ship. With all radiation shields maxed out, the ship has an initial delta v of 14,234 m/s, and without shields at all, 15989 m/s.

I'm considering maxing out the cryonics module where the crew will sleep and one of the modules where they could hide when a solar storm hits. The rest would have minimal shielding. That would give me around 15 km/s which is pretty decent, considering I'll get at least 500 m/s more after I dump the lander and one of the modules, as usual.

Any advice on this would be appreciated.

Well, the "storm shelter" is a very good idea that I think figures prominently in real-life plans.  However, it has the drawback of only working if everybody can get into it before the storm hits.  This is a function of warning time and what's going on with the mission at the moment.  I have no idea how much warning you get in Kerbalism, but even a couple of minutes should suffice for everybody aboard the mothership.  But what if you have some folks in a minimally protected lander?  Depending on how far away the lander is from the mothership, they might not have time to get back.  So maybe the lander should have max shielding as well.

I think the storm in Kerbalism is something that occurs suddenly in the whole system, with something like one hour of warning. I'm not sure, though. Timewarp also stops (and I think that feature can be turned off) so the crew being fried while in poorly protected parts of the ship is not a serious possibility.

The issue with the lander is totally possible, but I need to see the orbital periods in low Plock, low Karen, and possibly low Beros and low Kxy orbits. Realistically speaking, lander's shielding should be minimal and that would give me something more to panic about.

Which mod gives the smaller moons like Beros?

Anyway, if the smaller moons are about the size of Gilly or smaller, orbital velocity of the mothership would be in low 2-digits, and it would take an hour or more for an orbit.  And even once the mothership is in position to run back to, the trip back up to it would take forever as well.

This one.

Granted, if the conditions are similar to Gilly, I could get back to the ship on a hyperbolic orbit in a fraction of orbital period.

160 days in, Kaos 3 is crossing the orbit of Dres.

 

I won't be using AHMS for Kron 6. I'll go with regular heatsinks and radiators.

Also, I've tested the static stability of the ship using HyperEdit. It does not shake like a dog and is very stable. I'm still designing the staging system. New, 4 engine layout complicates things. I might return to a 3 engine layout. We'll see.

If you do, I may suggest using different (more powerful) engines?

What kind of thrust does the LV-NB make?

I've kind of sworn not to use anything else. LV-NB is kind of what makes Kron ships... Kron ships. Oh, and 3.75 m modules.

And they're quite realistic. After all, we do have that technology developed on Earth (NERVA, RD-0410).

CFG file for LV-NB says maxThrust = 160 so that would be 160 kN. In current, 4-engine configuration, I get TWR of 0.06 I've played with 0.04 before...

205 days - Kaos 3 is crossing the orbit of Jool. No solar storms yet, all systems nominal.
