(Forgive me if this isn't allowed)
So I wanted to post this onto the Minecraft Forums, but after seeing the Server section... oh dear Kod...
Anyway, I have a Hamachi-based Beta 1.7.3 server that, if anybody wants, I would be happy to give it to them. The only requirement is that you're LGBT-friendly because I have a girlfriend...
So, if anybody wants to join, reply here or PM!

I voted the Grox. I mean what race is feared by all others?
-
They've become what they hated, a community that has ridiculous pride and immaturity.
Just like how they saw the Roblox community as.
You become what you hate if you do nothing but hate.
And this, dude, is spot-on. Thank you so much for cementing what I always thought was the case but wasn't sure.

That doesn't make Minecraft a bad game though.
Let's face it, there is far more creativity available in MC then there is in KSP, quite a bit more freedom to do whatever you like.
Of course that doesn't make the community any better, I still love the KSP community, I've stopped playing KSP though after the move to curse ruining my ability to get my mods effectively.
Yeah, I'm not attacking the game in any way. The game is brilliant and I am a decent builder in it.
The community there is what bugs me. If you mention gold in any way... oh dear Notch almighty.

Oh, okay! I hear your point about the small fraction of players who post on Forums.
But I disagree about your "Some people doesn't want to play for real so crashes rocket into space station". That player would already have to know orbiting, rendevous, and stuff. All things that other people may be able to detect beforehand, and would take a lot of learning.
-
Yeah, I hear you!
Minecraft: Oh left click this, right click that.
LOL YOU NOOB!
KSP: Okay, starting my Hohmann transfer to the Mun!
Way to go!

So I finally have noticed that every Minecraft server is either giving EVERYONE admin status, lets you PAY for Operator status, or whines when you're a "tattle tale".
It's mostly just 12 year olds, especially compared to the KSP community where we all help out each other and can showcase our stuff and share techniques!
I basically decided to block everything containing Minecraft from my internet browser so I don't get sucked up into the drama that is that community.

Good job, boys! Colonize our solar system for the eventual war on the Kraken!
Well,I'll just have to sit in my little Latvia and drool over these juicy contests, waiting for multiplayer international contest!Who knows, maybe there'll be a Latvian contest in which you would win a potato.

Whackjob, we wish you luck on this grand project. May the Kraken be with you.

The device is under Utility and is called the Advanced Grabbing Unit!

OH, yeah, KSP is definitely DRM-free! If you set Steam to offline mode, I think all installed games can be played. But not installing, that wouldn't work.

ln is the 'natural logarithm'. It is a beautiful number in maths, but there is an ln button on most scientific calculators

You start with the equation that orbital period is proportional to the semi-major axis to the power 1.5. For a circular orbit, that's radius to the power 1.5. So T = k*(a^1.5) where T is time to complete one orbit, a is semi-major axis (or radius, which is usually close enough), and k is some proportionality constant that doesn't matter because it cancels out. In the case of Earth, we can set all the constants to be equal to 1. The Earth's semi-major axis is 1 AU, the orbital period is 1 year, etc. So if we say Earth is 1 Astronomical Unit from the sun and know that Mars averages about 1.52 AU from the sun, then we know that Mars completes one orbit in time T where T = 1.52^1.5 = 1.87 years which is about 684 days. Actually it's 687, but close enough since we're using approximations, and mid-course corrections don't tend to cost a lot of fuel.
Now imagine you want to do a hohmann transfer orbit between Earth and Mars. That means your orbit will have a perihelion of 1 AU and an apohelion of 1.52. That makes your semi-major axis equal to 1.26 AU. That means your orbital period is 1.26^1.5 years = about 1.4 years. You want to rendezvous with Mars, so you're interested in the outbound leg of this journey, so total transfer time is half that; about 0.7 years. So you want to launch 0.7 years before Mars reaches the point where it'll be 180 degrees from your present location. That's 0.7 / 1.87 = 0.37 of a Martian orbit. Times that by 360 to get 136 degrees. So Mars should be 136 degrees behind the point that's directly opposite to the sun from where you are now. Subtract that from 180 degrees, and you get 44 degrees. So you want to launch when Mars is 44 degrees ahead of you in its orbit.
So, to apply that maths to the Kerbal universe, you need to measure Kerbin's orbital distance from the sun, and call that "one Kerbal astronomical unit", or 1 KAU. It's always worth setting known values to 1 because it makes the maths so much simpler. Then, all other planets' orbital distances can be measured in KAUs. Plug in those numbers, and you'll get your optimal launch timings. The same maths works for orbital rendezvous, you just have to remember that semi-major axis is measured from the centre of gravity, not from the surface. So if you're orbiting 100km above Kerbin (and Kerbin has a radius of 600km), then your semi-major axis is 700km.
I know, I'm a crap teacher. If I were there in person, I'd probably be able to explain it better.
Thank you so much!
That is a wonderful equation and way to measure planetary distances! -
I've done quite a few missions using the old pen and paper technology. For figuring out TWR, delta-v, interplanetary transfer windows, orbital rendez-vous, the works. I find it so much more satisfying to complete a mission using my own mathematical intellect rather than mechjeb, transfer calculators or anything like that. Makes me think 3 years doing maths at university wasn't entirely in vain.
Can you tell me how to do the latter two?

Here's the real challenge: Use math instead of the map view to get to the mun, minmus, or even another planet by using your altitude, heading, and speed to figure out your orbit

R0cketC0der, What I did is only recalculate for stages that need to be reworked, and the stages below them. Saved me a lot of time just calculating adding liquid boosters to the bottom stage.
-
You can use calculator buttons and stats in the game:
For example: delta V is isp(exact same number as in game) * mass(full, take in-game numbers add up and times by 1000), and mass (empty, same procedure) * 9.81
-
This actually applies!

I just started designing my rockets using pen and paper and calculator, and I was wondering who else does?
What I mean is I do NOT use KER or Mechjeb; instead, I learned the equations for delta-V and TWR and I use them to design my rockets, from suborbital to orbital, and hopefully to the Mun someday!

Could somebody turn this flag http://imgur.com/pvKxCoD that I made into a good circular logo for .23.5?
-
If only somebody could make a phone app for this... that has certain responses linked to flight telemetry!
-
I've done it a few times
-
I see you are doing the Hardmode
H*** yeah! Maybe i'll even add a one-way lander for EVERY body!

No. After 66 challenges, it just became too much work to make ideas. Inevitable, yes. Thought it'd happen in my KSP career, no.

How Did Early Players Find Out Kerbin's Radius/Mass?
in KSP1 Gameplay Questions and Tutorials
Posted
In these newer versions, the information panel in the map view gives players access to many variables such as the GM of the planet, it's radius, atmosphere height and many other things. However, in the early days of KSP (like when it was free), players used actual mathematics to figure out Kerbin's mass. My question is how did they figure out the mass of Kerbin (probably using V^2 = GM(2/alt - 1/sma)) without knowing the radius of the planet?
