My Duna Expeditions (KSP 1.3.x / Heavily Modded)

Recommended Posts

This is a record of the exploration of the Red planet in the Kerbol system, including a variety of un-kerbaled and kerbaled missions.

A few additional notes on the missions. Some of this is based on experimenting with craft and timing for the missions (I'm calling them "simulations") where I actually run the mission, but don't save it to my main save game.

Mission Structure

  1. Unkerballed Survey Probe (Polar orbit)
  2. Unkerballed Rover (scouting for future ground facilities)
  3. Kerballed Ship with Lander
  4. Unkerballed Refueling Ship / Permanent Fuel Depot (higher Duna orbit)
  5. Long-term Habitat / Space Station (not manufacturing, orbit TBD)
  6. Kerballed Ground Facility
  7. Unkerballed Mining Rigs / Platforms (placement TBD)
  8. Ike-specific missions: Survey Probe, Landing Craft, etc.

This may also result in additional craft or infrastructure in LKO to support the Duna missions.

Simulation 001: Duna Survey Orbiter Mk1A (Not Successful)

This design was based largely on the Kerbin Polar Orbiter platform, with some communications changes and added Xenon fuel capacity.  The platform was successful in simulated tests around Minmus (i.e. alternate saves/quicksaves from the main save file), but apparently the propulsion and electrical systems were not adequately tested under full load.

This simulated version utilized a transfer stage for Kerbin escape and orbital adjustments. But upon Duna orbital insertion... with the Ion engine at full throttle... the nuclear reactor suffered a complete meltdown when core temperatures hit almost 200% nominal. The cooling systems were apparently not enough to keep it within proper temperatures. 

Additional testing will be completed after checking cooling requirements and possibly utilizing other cooling technologies.

Simulation 002: Duna Survey Orbiter Mk2 (Successful Reactor & Engine Testing)

Now we're getting somewhere. Here are shots from the LKO shakedown testing flight.

Running tests on the reactor and engines, it was clear that the upgraded cooling systems were adequate for the amount of electric charge needed. This platform comprises 2x 1.25m reactors capable of outputting 100e/s each, which is more than sufficient for the 180e/s requirement of the VASMIR engine.

While the two reactors were each able to run at 40-50% total capacity, energy generation also comes from the 4x large solar panels. This was enough to run the VASMIR engine at full throttle for a long time. And at 50% capacity on the reactors, their lifespace was well over 15 years. I'll need to evaluate if I can reduce to only 1x reactor and still have enough electrical output.

In that case, it will save a great deal of weight and increase overall dV for the craft. I'll likely maintain the large-ish solar panels, since they should still produce an adequate amount of energy in orbit around Duna (unlike out as far as Jool).

There's a creative pride that comes from this iteration process.

And justly so.  You make cool stuff.

Simulation 003: Duna Rover Landing System

I've got my unmanned rover ready to send to Duna, but I was experimenting with different ways to get it to the surface. For some reason... I thought there would be more heat coming in from orbit, so I started designing a system to cocoon it in heat shields (Spoiler alert: Duna's atmosphere doesn't produce that much heat on de-orbit at 900m/s... duh)

Anyway, it was a cool experiment and maybe I'll use it when I send something to Eve!

I didn't get any good screenshots during actual descent (I forgot to turn off 4x timewarp and it landed too quickly). Decouplers blew the top of the frame off. Then it kraken'd around for a bit until I was able to roll over away from the radiator & airbag mess. The landing legs were only to help tip over the frame so I could extricate the rover, since I wasn't sure how it was going to orient in the end.

I won't use all the heat shields for Duna, but I'm still using the airbag concept.

I like the look of your creations. They are all so pretty! Do you have a mod list?

Yeah, Duna's air is very friendly.  It's my favorite atmosphere in the game.  Too thin to be a problem but just thick enough to be useful.  Rather the opposite of the real-life Martian atmosphere.

Thanks! Appreciate your comment. 

Here's my mod list, if that helps (spoiler'd below).

I prefer mostly part-related and quality-of-life mods (tools, UI, etc.) rather than changing core mechanics of the game. And I haven't gotten into the whole USI/KIS/KAS/Life Support stuff yet.
