It is simply added immediately when you switch to the lab again.

Ahhh. Okay. I will try that tonight. Should I then not be time accelerating while I am in command of the science station then? I guess I will find out tonight.

Fractal: Maybe you should add a user-initiated 'transmit' button to alleviate the obvious confusion many are experiencing over this. The lab could say "xxx science stored" and have a transmission button which uses the normal transmit mechanics. Each science point could be 10 data units so it costs power to transmit and is a bit more obvious in how it works as well as more in line with the way data is transmitted in KSP.

That would be nice. It would alleviate any questions about science being transmitted.

I think he said he's already considering adding in a pop up window when you go back to a lab saying how much science got transmitted back to KSC. No button necessary. That'll be next update probably.

That sounds more annoying than anything. I don't like pop-up windows personally.

Anyway, I was just suggestion something to lessen the confusion and make it behave more like a stock system rather than a magical science fairy taking science points back home.

Hmm...

Alright, I have a few ideas.

To be clear, the design constraints are:

1. Fueled by antimatter (Does the reactor size matter to you? I plan to use the smallest)

2. Propelled ONLY by thermal turbojets (probably I'll use two, will see how it shakes out in testing)

3. Must reach orbit (We'll define this as >80km circular orbit) in a single stage, so no drop tanks or JATO/boosters. I could see a single-use booster getting it to orbit but you're wanting one which can get there on its own yes?

Any others?

Yeah no antimatter :) It's very easy with AM actually, you get so much thrust you're thrown out of the atmosphere in no time. And yes I'm trying to make a light ship, so I'm using the 1.5M reactor. I've tried using 2 jets, but that means 2 reactors and they are heavy. Right now I'm testing 24 intakes and 8 wings, I managed to get like 100m/s faster than before... I've ultraedited the thing on Duna though, and it works wonderfully well there. The only problem is landing horizontally at high speed with no runway...

Er... yeah dunno why I said antimatter, meant nuclear. I'll give it a try tonight and let you know if I can come up with a good design.

It's not a popup window, just some green text telling you how much science has been added. I wrote the code but haven't really tested it yet, it might make it into the update or not depending on whether I like it in practise.

It's very very difficult without antimatter, it was set up to be hard because I didn't want to make it easy to make SSTOs that consume zero fuel in the lower atmosphere until you had really got far through the tech tree or really worked for it. I haven't actually tested if it's possible, I suspect it is, but getting all the margins right is probably one of the most difficult tasks you could take on.

You probably want to use LiquidFuel + Oxidiser or Kethane propellant (if you have Kethane installed) because thrust is going to be the problem, more so than Isp.

I've not done it with the thermal jet but I have done it with normal turbojets and ion engines. It was a pretty dart-shaped aircraft, not a lot of lift to it. Loads of air intakes jammed on. Basically after clearing about 15-20km I'd drop the nose to 5 degrees above the horizon and just burn like hell. I needed to throttle the jets back as it climbed to avoid a flameout, but by keeping on as much power as I could with the nose just up a little bit it would accelerate to about 2,200m/s, at which point the jets would stop producing thrust (their exhaust velocity now matching the airspeed). They were each producing newtons of thrust, not kN any more when I lit the ion engine. It's easier to do with Mechjeb handling the throttle as it can jets right up to the absolute razor's edge of flaming out so you can get a lot more from them doing that.

I'm at work at the minute but I'll see if I can find the craft file when I get home if you'd like?

I've seen a video of a turbojet/ion spaceplane. I'm really juts trying to figure out if I'm using the thermal jet wrong or if it's just worse then regular turbojets on Kerbin. I know it's better on Duna, but if that's the only use they have before getting access to AM on the runway then it's kind of a shame.

Yes I'm using LFO with the lighest possible aircraft (7 tons), but because of the reactor weight as I said I get better results out of regular turbojets, which is a shame. It might consume zero fuel, but it has to carry a nuclear reactor and a radiator, which don't make up for the 100 LF I carry with my regular spaceplane to get it to the edge of the atmosphere. It's still great to tour Kerbin and make atmospheric readings of all the biomes I guess. :)

It certainly won't give you as much thrust as a basic turbojet on Kerbin, the small nuclear reactors just don't provide competitive power output with a jet, so their thrusts are lower. The low specific impulse also means it can't fly particularly high without running out of atmosphere.

Yeah, fission powered jets are definitely going to be inferior for SSTO applications even if you do manage to make it work. I think they come into their own in different areas, particularly long term exploration of other planets. If you can get them into space with a staged rocket, you can have a long term exploration vehcicle on Duna, Eve, Kerbin or Laythe. With a jet aircraft, it wouldn't even work on Duna or Eve and you'd have to worry about regular refueling on Kerbin and Laythe.

Help! When I am opening KSP and it is loading everything it always gets stuck at "KSPInterstellar-v0.7.4/GameData/WarpPlugin/Parts/Engines/MPD/part/MPD" I tried restarting KSP but it still does it! I have waited for about 15 minutes and it doesn't work! PLEASE HELP!

This is caused by installing the Plugin in the wrong location. If you unzip the zip file directly into your main KSP directory, it will work. Afterwards, you should have the WarpPlugin folder directly inside the GameData folder.

Alright then, thanks for your replies. At least now I know I wasn't doing anything wrong, just trying to use it for something it wasn't design to do. I'm definitely gonna try and bring one of those to Duna, if I can just figure out how to land it safely.

Why land it at all? Include a one-shot solid booster on the plane and strap it to the side of your duna spacecraft and slow down so that your orbit enters the atmosphere then cut the plane loose and re-circularize. Swap to the plane and fly into the atmosphere. fly anywhere you want to. When its time to leave, fly back up to the edge of the atmosphere and then trigger the solid rocket to bring you out into orbit. Dock with the spacecraft and off you go.

Sounds simpler than it would be to do, but it would be awesome if it works.

I mean we're talking about an engine that can run for years with no fuel. Why ever land? :P

I extracted the zipped folder I got by downloading it into GameData, IDK what I did wrong, is it because I left the zipped folder in GameData as well as the unzipped?

No you didn't. The path you posted says "KSPInterstellar-v0.7.4/GameData/WarpPlugin/Parts/Engines/MPD/part/MPD"

That means the mod is in a folder called KSPInterstellar-v0.7.4, not in the gamedata folder.

Copy the gamedata folder from KSPInterstellar-v0.7.4 to your normal kerbal space program folder and you'll be fine.

Copy the gamedata folder from KSPInterstellar-v0.7.4 to your normal kerbal space program folder and you'll be fine.

I am positive that I dragged the zipped file into GameData of Kerbal Space Program then extracted it into there.

It's supposed to be unzipped into your main KSP directory, not into GameData and there should not be a KSPInterstellar-v0.7.4 folder either.

There is a GameData folder inside the zip file to help you.

You could copy the three folders out of the GameData folder in your zip file into your KSP GameData folder if you prefer.

How do I take a screenshot of my folder :P ?

Nevermind. Do what Fractal said and see if that works.

You should end up with (KSPFolder)\Gamedata\WarpPlugin

Right now it sounds like you have (KSPFolder)\Gamedata\KSPInterstellar-v0.7.4\Gamedata\WarpPlugin or (KSPFolder)\KSPInterstellar-v0.7.4\Gamedata\WarpPlugin

If I have the Enterprise mod how do I use the Enterprise? Because it can't be in the tree can it? :P

It depends whether they added it to a tech node or not. All parts will revert to their default tech node if they aren't overridden by the tech tree.

Any parts that aren't assigned to a tech node will only be useable in sandbox mode.
