What is the one thing that you have learned while playing KSP?

[aven17]

If you can get into orbit, you are halfway to anywhere.

[Bigcheecho]

If you want to go somewhere, you have to thrust in a completely different direction than expected.

Second. I always thought that you go to a planet by pointing straight at it instead of doing it PROPERLY.

[LegoDino77]

I think Ive learned how to count Delta-V. Not sure thought

[LeonG17]

That MOAR BOOSTERS!!! will always work.

[Mr_Duke]

Always check that the hatch can be opened BEFORE you take of, many fails of mine included the hatch being blocked on landing!!!!

[WhiteWeasel]

The small cubis struts open up so many engineering possibilities.

[astropapi1]

When in doubt, apply more boosters!

[michaelphoenix22]

Never before have i had so much fun failing miserably and repeatedly.

[Dedjal]

Hmm... What has KSP thought me...

Never to say yes to go on a one way trip to Mars. There would be no accelerated time, and I wouldn't be allowed to touch anything funny.

And how a navball works! Clever little devicel do they work that way in real life?

[AmpsterMan]

The one thing KSP has taught me is that Orbital are very easy to grasp but non-intuitive at first.

[Hoa_Binh]

Every movie with space flight gets it wrong, usually when the ships burn pro-grade to slow down into an orbit.

[Phenom Anon X]

Orbital Mechanics.

This is the best community ever, I swear. I never run out of resources for learning something new!

[The Destroyer]

I learned that you cannot point at a planet and burn and expect to get there.

[Mephane]

That high gravity environments suck. Seriously, long-term space settlement is probably better off focused around asteroids and low-g moons and not planets like Earth. Getting stuff up the gravity well (or safely down) is so expensive in terms of fuel/energy needed.

[Rage097]

Orbital Mechanics. I now hate every Sci-Fi movie I watched as a kid.

[SkyRender]

There's definitely no one thing KSP has taught me since it introduced me to orbital and celestial mechanics, but the lesson I've gained from it of most value is that space itself is not hard to deal with. Indeed, space is quite easy. Having to deal with things IN space is where it gets tricky. I'd learned shades of this ages ago when I first realized what a harsh mistress gravity really is.

The problem with that is long-term low gravity can have bad effects on human development, if you neglected it you could fall seriously ill should you try and return to Earth.

On topic: That the biggest obstacle for a larger scale of kerbal expansion is unity 3's limitations.

[DisarmingBaton5]

SRBs are the answer.

On a slightly more serious note, I learned that velocity and altitude are relevant to each other, and not two completely seperate factors.

[XenonSpark]

Orbital Mechanics. I now hate every Sci-Fi movie I watched as a kid.

This. 100% this.

[The Destroyer]

Yea physics suck for sci-fi. But I understand why, and I still like them

I find this community to be anything but that, most of my assistance has actually come from the Celestia community at shatters.net.

[Kcombs75]

I learned how hard it is to go to other planets. Going to the moon was big, but after getting to Eve/Duna I now realize how hard it must've been for NASA to land a rover on Mars. Didn't fully appreciate it until I "did" it.

[TriggerAu]

Orbital Mechanics for me as well - and a scary amount of it

[Mr. Rogue Ace]

Ha! I knew that from space shooters! If you want to shoot the enemy, you have to aim in front of it.

[Mr. Rogue Ace]

I knew that there's gravity in space, but didn't know how it presented itself with orbits and such
