Eve Luxury Floatation Aerostat Habitat

Recommended Posts

*"Orbit" means the lateral movement of your craft across Eve in a clock-wise direction, similar to what it would be on Venus in real life. See Rule #4.
**Use of Hyperedit is prohibited for everything except tests of your design. ²I don't need pictures of your tests, however, you are welcome to provide your development process.
†See modlist.
††Not compatible with anything of similar fashion. E.g. having ten Kerbals is not compatible with twenty Kerbals. You only get points for the twenty Kerbals, not twenty and ten. Applies to more than two terms also.

The Eve Luxury Floatation Aerostat Habitat (ELFAH) challenge is one of the hardest, most captivating, and most difficult ones in the history of Eve challenges.

As some of you might've known, the HAVOC project has been developed by NASA. The plan consists of five steps:

  1. Robotic exploration into the Venusian atmosphere
  2. Crewed mission to orbit Venus for 30 days
  3. Crewed mission to Venusian atmosphere for 30 days
  4. Crewed mission to Venusian atmosphere for 1 year
  5. Long-term human presence in a floating balloon.

This, as-well as my own fantasies, has challenged me to get back into KSP and try this out. However, this summer I am moving to California, and my YouTube channel is taking a very serious turn now, so uploading a silly KSP video will be..well..silly. Therefore, I challenge you, the KSP forum community, to complete this challenge! I did do something very similar about a year ago, and it worked alright until I lost control of the ship and crashed into this mountain over here:

Now, for the challenge rules and similar, less intriguing things:

˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘RULES˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘˘

  1. Please no cheaty methods like Kerbal ladder propulsion or similar. Come on lads, I have faith in you!
  2. Version 1.0 or later, please. Old versions are subject to approved exceptions.
  3. Maintain a manageable part count. No more than 800 parts please.
  4. You must "orbit" around the Equator, or somewhere close to that. Polar orbit is fine as-well. No diagonal or weird-shaped orbits.*
  5. Altitude requirement is to be no less 12,500m and 60,000m. 12,500m is not very survivable, and 60,000m is.. well.. it's just cheating at that point. The in-betweens are up to you.
  6. Your craft must be able to haul at least four Kerbals.
  7. It's a shame that there is no wind on Eve at this time, so you will need to use propulsion. It needs to be 100% sustainable, Eve doesn't need any more carbon than what it already has! The speed of movement must be no less than 10 m/s and no more than 40 m/s. Ion engines (good luck with those), KAX propellers, and other, electric-powered engines / props are allowed.†
  8. The way you get here matters! Provide plenty of documentation (pix) of your trip to Eve. I don't need more than five. Use of HyperEdit is highly prohibited.**
  9. The craft must be stable (altitude-wise). I know it's hard, but it's more than possible. I've accomplished it myself, before I did something wrong and crashed. Do note that my attempt was in version 0.25, and that was a while ago, so a lot of things changed from then, but I have to assume that it's still possible.
  10. Documentation: Papers, Please! Please provide ample documentation (pix) of your entire mission.**²

+ 2,000 points: your craft carries 100 Kerbals.††
+ 2,000 points: your craft is under 100 parts.††
+ 5,000 points: your craft is primarily propelled by ion engines. Eve atmosphere.
+ 5,000 points: your craft carries more than 100 Kerbals.††
+ 7,500 points: your craft gets to Eve primarily using electric propulsion of some sort.
+ 10,000 points: your craft consists of a main module, several transportation vehicles for transport around Eve or from base to base, and has many great things that an on-ground base would have.
+ 20,000 points: your craft is reusable.
+ 100,000 points: your craft is 100% stock.
P.S. Let me know if you find any rule / judgement unfair or confusing. I will fix it promptly.

Is it possible to hover EXACTLY at 0 m/s in Eve's atmosphere horizontally and vertically? This challenge sounds interesting, just wanted to know.

This sounds insane. I figure it should be possible, if you give the balloon enough time, and with decent balancing. I hope a new submission comes up. Please.

With enough balancing, yes. It won't be realistic though, because real life Venus has a huge amount of winds in the atmosphere.

Challenge accepted.

All you have to do is enter the atmosphere, deploy the balloon, activate the auto balancing, and wait for the drag to stop all horizontal motion.

Either everyone is having trouble or no one is interested. Most likely the former :wink:.

I'll try something on my own in a couple days.

"Maintain a manageable part count. No more than 12,000 parts please."

 

Erm, what?  Is that even possible to have that many parts?

64 bit has changed some peoples' definition of "reasonable" if they have beefier computers. <.< (I'm assuming 12 hundred, not thousand)

Yeah. I might change that soon.

I personally find 5,000 500 parts my absolute limit. That's when framerate nopes into oblivion.

Some people, on the other hand....

 

Oh God I'm not looking at what I'm writing am I? Why am I writing in thousands?!

Fixed.

Mostly fixed  :P
"+ 200 points: your craft is under 5,000 parts.†† "

 

Regardless, glad to see I wasn't actually vastly underestimating the power of KSP xD

Corrected. I apologize for my carelessness. :P

l kind of want to try this all-stock. It should be more than possible with a large-wing plane, using an SAS powered turboprop, or with good old kerbal pedal power.

...providing i understand this challenge correctly. From what i can understand, the challenge consists of a crewed ship that can fly between 10m/s and 40m/s, at a relatively steady altitude between 12.5 and 60km, and regenerates electricity so it can theoretically fly forever, accompanied by some kind of orbiter ship. Did i get everything?

Also, is kerbal engineer allowed when designing the ship? I sincerely hope so.

Orbiter ship (I assume one in space) is not necessary. Yes, steady altitude, between 10-40m/s, and theoretically infinite flight. Please no pedal power though :P

Kerbal engineer allowed, yes. I should probably specify that also.

Alright, I said challenge accepted earlier, but my computer doesn't like me taking screenshots of KSP, so it's going to be a while till I get the pictures. However, I did make it and stabilized the vehicle in the upper Evean atmosphere.

Once again, I'll get pictures soon. Probably have to redo it though.

Making progress on the stock version:

Created a compact sustainable propeller plane that should be sustainable at low eve altitudes. I could bolt some seats on to the wings and call it done.

Is it reusable, quasarr? That would be epic, although I have no idea how you would achieve that result. 

Nice to see people interested in this challenge. My submission coming in a day or two, it won't be ideal and will most likely not get any extra points.

I'm a bit confused by the propulsion mechanism on your aircraft. Could you please post more pictures of the prop?

Got to levitate a small unmanned capsule in upper Eve atmosphere. No propulsion, simply hanging at 30,000m.

Totally possible, this challenge is.

My mission is very similar, just that mine has some electric props on it for movement and landing legs for leaving to the space center. Also has two crew.

The minimum is four. Do you plan on having two and then connect them with Infernal Robotics or something like that?

What is the powerplant? It can't be jets, obviously...

You did beautiful. Can I have some stats about how many it carries and what speed and altitude it hovers at?

This is a wonderful submission. Congrats.
