This was a tough one. I'm not sure if I should carry on with this game considering it's about to go gold, but all the mods I'm using that will still be relevant in 1.0 version will take a while to become fully compatible with 1.0.
You asked for 3 - a permanent settlement in Minmus. That shit is very, very expensive, so it will take a long time for it to actually become self-sufficient. Furthermore a logistical network to bring Karbonite all the way to the KSC was a more immediate priority and it ain't cheap either. And finally, once I have enough funds to risk sending all the components needed for a self-sufficient base, I will have to fire a lot of pilots to give room for more engineers to keep that base running because I can't afford upgrading the Astronaut Complex, not at all.
I also realized that I'll need the Docking Port Sr. to have stability for the kind of modular spacecraft of the dimensions needed to make the Karbonite economy happen in a pace that isn't horribly slow, as you will see.
And this is the final update in this page.
=========================
Orbital Logistics
Colonial Anthem
While a new pilot was recruited,
JagreenLern would probably not have many missions this year, for budget limitations meant the Afrikan Union could only choose between having a permanent manned colony and mining operation in Minmus or a manned mission to Duna, and the choice was already made in favor of the former, because transforming space exploration into an economic activity would forever change the space program.
The first module of the Minmus kolony, the C3 Command and Control Center, would be entrusted to Hellraiser and Bastard4, who would be the first ones to go in a journey towards a new home, at the dawn of the age of space kolonization.
Sixteen boosters were needed to put the heaviest Afrikan rocket ever built into orbit. A tug design with four of the recently developed nuclear thermal engines, docked with the C3 Command Center. The nuclear powered tug would be reusable, with the goal of docking with the transporting modules from low orbit to the surface of Minmus.
The first stage ended without incidents.
Heavy, with poor thrust for their weight, yet extremely fuel efficient, the nuclear engines were started far away from the atmosphere. It would be a long way to Minmus.
Plenty of life support was available. More than an entire year of food and oxygen for the two engineers and four months of water that could be recycled through a filter on the top of the command module.
While the Command Module was on the way to Minmus, for the coming reuse of its nuclear tug, to take advantage of something put into orbit as part of an old contract, back when docking ports did not exist, an "adapter" was launched in an intercept course with the Training Akademy, which would be brought to Minmus so the most skilled engineers would be able to pass their knowledge to the rookies, ensuring a high efficiency once the kolony becomes operational.
The "adapter" was successfully attached with the Training Akademy, now ready to be brought to Minmus, but first, the vessel that would transport it need to unload the current module docked to it, and the two engineers inside would need to EVA and detach several struts between the module and the tug as well, struts added in the design because of the stresses of launching two docked components from the atmosphere.
After several maneuvers, the landing begins.
Multiple course adjustments happen near the surface to get it as close and aligned with the central mining and refinery module as possible.
The first objective of the
Modron Transfer Module is completed.
Bastard4 connected the recently landed Command Center with the refinery. The struts were detached and then, remotely operated, the upper module takes off shortly and lands nearby, where it is then connected through a pipe and refueled for the trip to bring the Training Akademy here.
This was only the beginning.
Months would be needed, for launching a second nuclear tug was out of question with the available budget.
All existing contracts on Minmus were fulfilled in the most Kerbal way.
Yet the pilot luckily survived such very low pass flight through an airless and very low gravity surface.
And with the experience from the contracts and shared knowledge, finally a critical component for the plan of starting up a space based economy was ready for construction: a massive heatshield, essential for a concept of a manually controlled transport device for Karbonite.
The Akademy will be much trickier to land on Minmus, but doable.
While the tug was heading again towards Minmus with a new module to land near the existing kolony, a new concept besides the tried and tested MORE MORE MORE BOOOSTERS was being attempted: Multiple reusable fuel tanks to bring a massive volume of empty Karbonite tanks into a stationary orbit with a direct line of sight down to the Kinshasa Space Center. Because of its massive weight, a much more powerful engine was added to this rocket: the Skipper liquid fuel engine, which will begin lifting it in upper atmosphere.
The separation from the boosters happened without problems. Fortunately because mistakes were unaffordable considering how expensive launching all the modules necessary for this great project would be.
The launch was done in a very efficient manner, but the desired orbit was still far away.
Again the Sun is eclipsed by the Mun. Fortunately the batteries of this unmanned module were just enough to outlast the eclipse.
Another innovation, a separator finally splits the Karbonite storage from the engine that brought it in this synchronous or almost synchronous orbit. A new technology: 100% automated logistical drones, could revolutionize everything, but it was an untested technology. First it would be tested on the surface, to bring fuel from the KSC to some orbiting modules.
The first "truck" with the logistical hub did not work very well. After several failures, it became obvious more wheels were needed for this weird jet powered automobile.
The mistakes were corrected, but it would need to be connected to extra fuel and Karbonite tanks to serve its role well.
Driving trucks was a bit frustrating for those hoping to go into space, but these trucks would be very important for the future of the Afrikan Space Program, for they would receive Karbonite from outer space once the logistical infrastructure was ready to deliver the precious resource all the way from Minmus to the KSC.
And finally, for the sake of testing the Logistic drones, a jet-powered tanker because for some bizarre reason the Afrikan Space Program cannot into procuring normal big trucks.
The tests were successful, and with the confirmation the drones work, it was time to send one of these modules up there, to dock with the Karbonite storage in its stationary orbit.
This was in no way a cheap launch. The stakes are much higher compared to the days of dirt launchpad and Tropospheres.
Good.
From this finally ready space station, Karbonite will be transported to Afrika.
But, as a proof of concept and propaganda showcase, a manual transfer of Karbonite without using the drones in atmospheric entry would also happen. It was uneconomical and very risky however, and such drop pod method would not be repeated mostly because the cost to put it into orbit is higher than the worth of how much Karbonite it can bring back down. The second purpose of this was an attempt at the first Single-Stage-to-Orbit Afrikan rocket, through the use of the mighty Mainsail liquid fuel engine beneath three massive fuel tanks. This would in the future serve as a refueling station for future SSTO spaceplanes, once they actually happen.
The SSTO experiment would enter History. It would be the first successful one, supposing it works.
Another proud moment for Afrika, the first successful SSTO rocket is about to leave its payload in low orbit.
A second SSTO rocket was launched with a critical module for all necessary Karbonite transfers.
Meanwhile, the tricky landing of the Training Akademy was about to begin.
Keeping the tug pointed towards the right direction during landing was tough.
But it worked, and rather than having to head back home to become a two-stars engineer, Hellraiser would simply learn from the somewhat higher experience of Bastard4 who was one of the three pioneers in Minmus.
Maybe that aeroponics module could be reused too.
Sadly, it couldn't ,for it was exclusive for orbital stations. A new Aeroponics module would have to be launched with some inflatable agriculture modules in the future for Minmus to eventually become self-sufficient.
To help with budget concerns, two new satellites will be put in orbit of Minmus.
The old design is upgraded with more fuel and more boosters, of course.
"Upgraded"
...
There is only one solution:
THRICE MORE BOOSTERS!!!
See? It totally worked! All aerodynamic aids were also successfully ejected.
Meanwhile, back home, the Modron nuclear tug docked with the Karbonite transfer module and was bringing it to Minmus, where it would be fueled up. With the new satellite contracts, while a manned mission to Duna was too much risk, that did not mean the window of opportunity to reach the distant red planet would be completely wasted.
Fremen-I, a double probe driven by two atomic engines fitted with very long range communication devices and a massive arrays of solar panels, with a ridiculous quantity of detachable fuel tanks, the tallest rocket ever constructed by the Afrikan Union Space Program. Its mission: the complete mapping of Duna and its satellite Ike. Because of the advanced sensors they carried and of the nuclear engines, these would be the most expensive probes ever launched, but having a perfect map of Duna before considering manned missions was priceless, and maybe Ike could have like 50%> Karbonite reserves instead of the meager 6% ones of Minmus.
Excessive, ridiculously big. It did not matter. Getting to Duna without fancy docking maneuvers and launching multiple less heavy modules separatedly as any sane space program would do is not trivial. But it is a lot more awesome.
The first stage pushes the massive rocket to the edge of atmosphere, and then it is maneuvered for a late gravity turn shortly before losing the momentum of going up, for it was literally impossible to turn it before this altitude was reached because of its massive size.
The result of all those solid boosters was pretty good. From such high orbit making a maneuver to encounter Duna after some months would not be so hard.
It is unfortunate a manned mission was too risky, but the transfer window is about to happen.
It would take many months. A lot would happen before the Fremen-I probe reached its first destination. First? Of course! The Fremen-I was designed with a large surplus of Delta-V, and while going farther away from the sun will be perhaps a bad idea because of the loss of efficiency of its solar panels, it may have still enough after fully mapping Duna and Ike to get itself into another planet.
(Could I get from Duna to Jool with this without running out of power because of the loss of solar efficiency, supposing it has fuel left for it? It's basically one gigantor for each probe. I will leave one orbiting Duna and carry on with the other. )
While a very complex probe is on its way to Duna, another landing is happening on Minmus, this time to ship the precious Karbonite all the way back home. A pipe is connected again, everything goes well.
The transfer of Karbonite to the surface of Kerbin just began.
After regretting deeply the choice to not have RCS for the sake of saving fuel, finally the Karbonite transfer module was successful docked with the keostationary depot and logistics hub.
Now the hub would be programmed to fill the empty Karbonite tank of the drop pod in low orbit while the Modron nuclear tug would head on its way to dock with the same, set it in a reentry, undock and then accelerate again into a stable low orbit while the drop pod begins reentry.
Hopefully it would look great for pictures. The tug successfully left the pod in a reentry trajectory and accelerated back to a stable orbit with more than enough leeway for the same to not end being lost in reentry.
The heatshield proved to be exactly what was needed for this design, no more, no less. A smaller one would have failed.
Yet unfortunately, the drop pod landed right into the middle of the mountain range west of the KSC... and it was going down still too fast.
...
This whole show with the drop pod was a bad idea.
However, with only one minor difference in the reentry maneuver, this would not have happened, but instead it would have landed safely and quite close to Kinshasa. Nevertheless, this was not how Karbonite would be sent back home. Manually landing drop pods may sound awesome, but it won't work most of the times and of course, the launch costs wouldn't be paid off by the Karbonite it would have brought, were it successful.
Instead, two additional logistics modules would be launched, this time in a different, cheaper way involving only a handful of liquid fuel and mostly, of course, solid boosters.
First attempt with six boosters in stages of two activated each time was a fiasco that did not even take off, fortunately, because an emergency team managed to recover it, preventing financial losses. Second time, the natural solution of doubling the number of solid boosters would fix everything, and then the nuclear tug would dock with the logistics hub, and bring it to Minmus.
There was however one "minor" design flaw of this new logistics hub module: its engines would bring it nowhere while its solar panels were raised because they blocked the four small engine exhausts. Not something crippling, but still a sign the old Kigerian "genius" never died.
Because its own engines were less efficient, they were disabled while the tug was bringing it where it was needed.
The second module would serve a very interesting purpose once the first one lands on Minmus and is connected with the Kolony.
This time the maneuver was so well done the solid boosters alone almost managed to achieve a stable if eccentric orbit.
By the time the logistics hub touched down on Minmus, the mistake of a Kongolese who mistook the flexotubes that can be extended by engineers with unflexible, rigid docking ports because they look exactly the same was realized... taking away flexotubes from the Command Center was not a good idea. But with enough stubborness, after removing one of those docking ports and attaching it to the Training Akademy so a tricky docking maneuver can be made.
(Unfortunately the Akademy doesn't work at all and is bugged. Am I justified to edit extra stars on engineers to simulate it working as intended in its description?)
But before anything, the tug was separated after most of the docking while landed maneuver was done and now the most delicate segment of this would commence. As the other module had its own engines, it would be easier to do succeed this way.
It worked... and while strangely the docking caused the two modules to climb up somewhat, nothing fell into pieces and they landed softly enough to remain unscathed. Now there will be no longer any need of landing for the sake of transporting Karbonite and fuel, only for the sake of bringing in the countless remaining modules necessary for this kolony to finally become self-sufficient.
The Karbonite Transfer Module had docking ports above and beneath it for a reason.
For that component would be the centerpiece of a modular Karbonite and fuel transporter.
Note to self: don't ever refuse to add liquid fuel RCS to a tug design as a cost cutting and fuel saving measure again.
Away from the large depot and docked with the tug, the Karbonite module will now be docked with something else, and then the tug will play a fundamental role in the startup of this space economy, because the logistical drones cannot simply transport Karbonite straight from the surface of Minmus to the surface of Kerbin.
Almost everything is ready, but this will probably take months because a much larger, heavier and more expensive tug would be needed to make it goes faster, and more Karbonite drills on the Kolony would be needed too.
The first shipments will happen.
Water was less abundant in the Kolony, and so many months already passed it became necessary to activate the filter.
This is how the startup shall work: first, fuel and Karbonite from the surface are transported by logistical drones to the Modron Transfer Module, which once filled would maneuver to escape from the sphere of influence of Minmus.
Then, still relatively close to Minmus but out of its SOI, the Modron Transfer Module, docked with its own Logistics Hub, shall transfer as much of its resources as possible to the keostationary Karbonite and fuel depot with yet another logistics hub, the same one that has a direct line of sight to the KSC.
Then the Modron Transfer Module would maneuver back into Minmus. Rinse and repeat until the keostationary depot is completely filled.
A much larger Transfer Module was certainly of great need because of how sluggish this logistical infrastructure with budget and technological limitations currently is. For now contracts cannot yet be dismissed as a primary source of funding. Luckily there are two satellite contracts signed for Duna and Ike which shall greatly increase the budget once completed.
Nevertheless, while this volume of Karbonite is worth just a few thousands and required all liquid fuel and oxidizer stored in the Keostationary depot to be brought to the surface, this was just the beginning, and it proved the viability of the Kolonization and economic development of Minmus. For the first time in History, space exploration became productive, even if the return of investment will take a long, long, long time to happen right now. With the surface logistics hub and the tanker superfluous, mute is sent to disconnect them, after which only the Karbonite big truck, ready to receive future shipments of Karbonite from outer space and refitted to become 100% remote operated, stands ready for more. Once completely full, it will bring 10k extra of funds, far from the best contract rewards, but not so bad for this humble start of the greatest enterprise upon which Afrika has ever embarked.
TO BE CONTINUED UNLESS ALL MODS STILL RELEVANT WITHIN BECOME COMPATIBLE WITH 1.0 SOONER THAN I EXPECT
