Mode 0 seems stupid but then you can focus the camera only where a plant is not where a planet will be so it makes zooming in your future periapsis easier because you can click the body and zoom in and your path will be there

I'm having trouble using the navball to orient myself correctly to change my inclination. What i did during my last munar attempt was to point my craft directly at the nearest celestial body, ie the mun, then orient the next closest body to the left of my craft, then in theory by going into the map i could determine my craft's orientation in relation to everything else by looking at the relatonship between my craft and the 2 other objects. I then attempted to reduce inclination by pointing my craft at the opposite direction to the undesired inclination and burning in the hopes that would change something, now i realise this is probably the most fuel inefficient way of doing this and any change should and B) my orbit was actually getting more massive, probably because also due to an error my speed was increasing.
I gave up trying to make my inclination match the solar plane again and instead went straight to changing my orbit to match the muns. I almost suceeded, i had my orbiter orbiting kerbin at 11.5 million kilometers and travelling at 580 Km/s and just barely catching up with the mun, It was in my sights perhaps 200,000 kilometers away.
I pointed my craft straight at the damn rock and burned without any thoughts of bothering to line things up correctly, that's when i noticed my inclination had basically levelled out by itself during all the proceding burns i had made to match orbit and speed.
Anyhow i ran out of fuel and ended up with an orbit that almost touched the mun every 20 years.
Good times.

Inclination is always changed by burning 90 degrees up or down from the direction of travel. If you were travelling on the system plane, you'd burn directly north or south at the horizon. If you were travelling in a polar orbit, it would be east or west at the horizon. Inclination changes are always at the horizon.

EDIT: Also, unless you want your apoapsis or periapsis to change you'll need to change your heading as your inclination changes.

One way trip, because I dont have enough fuel. Also due to lack of decoupler, the entire bottom part of the rocket was torn off anyway when the parachutes opened. Oops.

After many failed prototypes (about 20) I have finally completed the Reverse craft:
Reverse Engineering MK2
Spoiler (click to show/hide)

It drops the fuel tanks from the top instead of the bottom, like so:
Spoiler (click to show/hide)

It brings a super heavy interplanetary stage into orbit:
Spoiler (click to show/hide)
That's 3 and a half 3M fuel tanks, 8 1M fuel tanks, 8 Nerva engines and 1 small 3M engine(for lifting off from atmospheric planets).

This beast can easily reach Jool, and with clever air breaking, could probably land on one of the rock moons.

Flyby of Tylo with a nice Jool rise:

In orbit over Jool:

Fatal splashdown on Laythe:
Spoiler (click to show/hide)

I did actually manage to "land" on a small island on Laythe, however there was a mixup at the factory and the craft was outfitted with small landing legs.
The craft landed nicely on the beach with a solid 2m/s but bunched off the engine, since the legs were too short.
I "forgot" to take pictures out of shame.


I was figuring on just settling Laythe since it seems impossible to get back to Kerbin from there, since it has about the same atmosphere.
Jool is seriously Hard Mode.

I was just about to come in here and post similar screenshots, except with less rocket remaining. Dam.
Atmosphere of it starts at 55000m btw.

I think i've got a design that will allow me to launch a rocket that can reach duna and return. Its based off the assumption that a single NERVA engine on 1 and a half 3m diameter tanks is enough to get the 3 man command pod home from duna orbit. Is that a good assumption?
Secondly, has anyone managed to land and take off from duna before? any idea what sort of rocket one needs to do it?

edit: the maths says you only need an escape velocity of 1500m/s to return to kerbin once you are in a 50km orbit of duna. In that case 1 and a half tanks of fuel is probably overkill.


edit: have some screenshots

The second is quite possibly one of the most amazing things i've seen in a sandbox game.

Is laythe habitable?
The surface is almost covered in ocean, question is: is it water?
It's very far from the sun, so it has to have some other way to make the water liquid.
Could it be lot's a greenhouse gas + tidal strain from Jool? (like Europa)

EDIT: are you landing on Laythe in both pictures? what does the launch stage look like?

EDIT2: Remember that the atmosphere is blue, and the colour represents it's chemical composition. Can you get this kind of greenhouse effect with a blue atmosphere?

The sun has a body! And spots!

Anyone else noticed? 'Landed' on it?

actually, it works fine in .17 from what I can tell... only minor hitch is that it may not place kethane deposits on the new planets unless you're starting a clean new game.

(i.e. You had Kethane installed before .17, upgraded, and are still using the same save.) I'm not entirely sure about that though.

In any case, I've already got a mining operation going on the mun, after my third attempt landing. First ended in non-destructive failure. The rocket just tipped over on the Mun. Kerbs were fine and are waiting for rescue. Second ended up much the same way, except with more explosions. Kerbs died tragically. Third ended up well enough with a bit of mechjeb help.(It was dark and I couldn't see to land and didn't have enough fuel to boost myself back up into orbit for another attempt in brighter conditions.)

I've also heard reports that people have found kethane not only on Duna, but the moons of Jool as well.

EDIT: you know those recommended videos that come up after watching a video?

http://www.youtube.com/watch?v=inkkLAfFIbY&feature=player_embedded
this is brilliant.
That was fantastic.

This video is nowhere near as good, just me putting my first satellite into orbit. Still, I'm learning. I thought the cowling was interesting, and I'm still tweaking designs.

arright!

getting kethane mod!
also, I like that moon jool has that has oceans etc. on it. I can imagine that being one of the first planets to colonise, in the game.

this is brilliant.

I don't know about that. The first place I'd colonize is Minimus; with its low gravity, a large ship can leave there much more easily than Kerbin, allowing more payload per mission when going elsewhere. Meanwhile, getting to Minimus is relatively easy for even a rather large payload.

Low polar orbit is probably best for mapping, TBH, as over time, the whole planet will be mapped, not just one area.
Yeah, the equatorial orbit was just to test the satellite. I have one in high polar orbit (400km orbit). With two scanners, it maps pretty decently even at 400k and gets a very wide area on each pass. This image is from only a few orbits, you can see how wide the mapping area is per pass.

I'll just pretend this things are advanced remote controlled machines that wage war on a planet completely unrelated to Kerbin. And this war will never reach it.

I can't help it, I like goofiness of KSP to much to see little green guys intentionally blasting each other with those serious-looking, cold machines of war.  :(

But that aside - nice video and some damn nice models.
