1. ## A potential way to solve the N-body problem.

Hello guys, I see this discussion has really taken off, so to clarify some misconceptions: One, I did not know that the calculations would be so easy on a computer, so therefore the trajectory calculations could be done more frequently. Two, I decided to keep the planets on rails because as we can see in our own solar system, planetary orbits do not change much over the course of a typical long-duration mission (10 years), or even in a lifetime.

Jupiter for the NASA launcher, and Blizzard for the Buran. That is my opinion though. Tyr should be used for another, possibly bigger size orbital module. Styled after the odin, but beefed up for interplanetary missions.
3. ## A potential way to solve the N-body problem.

Hey there forums! Here is a possible way to solve the N-body problem, not that SQUAD must implement this though. Since the equation for the combined gravitational force between 2 objects is Fg=(G*m1*m2)/r^2. You could just sample that equation once for each body for each physics step, and in order to draw trajectories in the map view, you would sample that equation for all major celestial bodies on the kerbol system, therefore all planets if you are primarily bound to kerbol. In the case that you are orbiting jool, all of its moons will be calculated, as well as the major planets (including dres and eeloo), but not the major planets respective moons. One exception though, the gravitational forece from duna and ike will be averaged together first because of their relatively similar sizes. Once all the vectors for the gravitational attractions are averaged together, there is the gravity vector you apply to the space ship. This will be modeled for all ships with command pods, so calculations for debris will not bog down your CPU. Those said ships will then have their orbits calculated in advance in reasonable steps, such as every minute, in such a way as every hour, on the hour, the game calculates 60 new steps for the orbital path of non active vessels. Those trajectory points are them smoothed through a spline-like system to generate a smooth path. For time warps of higher than 1,000x, the calculation intervals will be spread out to one hour between each. Or faster if you have a better CPU (interval will be set in settings.cfg). Hopefully you will have understood that, and if not, send me a PM, or the same if you simply would like more info. Just to clear up any confusion, I will NOT be trying to add this to the game in a mod, but if any more experienced modders (ferram4, NathanKell , and r4m0n in particular) want to try this, I am all for it.

The mysterious ring of mountains on the opposite side of the planet as the big crater is the combination of the shock waves formed by the impact, shifted northward by plate tectonics.
5. ## On which planet did you Aerobrake for your 1st time?

Moho used to have an atmosphere. It overheated your parts like crazy. That was back in 0.17 though.
6. ## A Plan to Save Mankind

What about launching giant space-lasers or mirrors to cause the object to violently outgas. Since this dwarf planet would collide with us in 30 years, it would have to be from outside the solar system. Otherwise it would have been discovered long ago. That means it will just be a giant comet. Or we could paint the entire thing white, and let the Yarkovsky effect do its job. Or, hope the moon is in the way, and hope no baby-moonlets hit us.
7. ## Competition or cooperation?

Agreed, it also can spur innovation, and interest people in space.

Here is one of my best launchers. Moderate part count (155), serial staging (no asparagus), and plenty of delta V to boot. May I present to you, the Carinae UHLV... It can lift 72 tons to orbit reliably, possibly more. Downloads: http://www./view/p9uduvck63v4zhz/Carinae_UHLV.craft Spica
9. ## Airplane from two days to today becoming impossible to control !

Did you install or uninstall any mods, such as FAR.
10. ## Is a mach 10 aircraft possible with stock parts?

That is NOT possible in stock ksp, look at the CFG of the turbojet. He edited it to go faster. Spica
11. ## Why are so many people opposed to nuclear energy?

I feel the same will happen to Indian Point Power Plant.
12. ## Why are so many people opposed to nuclear energy?

Sadly, too many people are horribly ignorant in this world, and don't care to learn anything that doesn't directly affect their lives. Spica
13. ## Show off your awesome KSP pictures!

The engine is on the TOP of the lander. B9 aerospace low profile engine. Spica
14. ## [1.2] Real Solar System v12.0 Dec 8

THANK YOU THANK YOU THANK YOU THANK YOU THANK YOU THANK YOU THANK YOU THANK YOU THANK YOU THANK YOU THANK YOU THANK YOU THANK YOU THANK YOU THANK YOU THANK YOU THANK YOU THANK YOU THANK YOU THANK YOU THANK YOU THANK YOU THANK YOU THANK YOU THANK YOU THANK YOU Seriously NathanKell, you ARE the best. (Now, if only Kragrathea would follow your example). Thank you VERY much Spica
15. ## any other rocket families?

I am currently working on the Heracles rocket family, will post pics tomorrow. Spica
16. ## This game is way too frustrating

Agreed. (10char)
17. ## TSP (Tau Space Program 1.2)

Wait, so you have been playing the game for just over 2 weeks, you have defied the KSP learning curve, with STYLE. Spica
18. ## What did you name your first rocket?

Moho I Mercury, Moho, Mercury, Moho, Mercury Moho... You get it by now. Spica
19. ## Career mode is awesome and what I would like tweaked.

I would say a sort of hard drive needs to be added to store data, and as Nobody said, a sort of sample-return container for those unmanned landers, as well as a sample-collection arm. Spica
20. ## What do you want in 0.24?

Isn't it a little early to be thinking about this, but I would want a Hard Mode anyway. Spica
21. ## This game is way too frustrating

One question, did you just buy the game, or have you owned it for some time? If you are new to the game, it does have a VERY steep learning curve, and I would recommend trying sandbox first and flying some of the stock rockets that come with the game. If you simply don't know how to play the game, you should look up scott manley, and watch some of his KSP tutorials. You must keep trying, because this game is NOT easy to learn, but in my opinion, it is the best game I have ever played. Spica
22. ## Real-life based tech tree

There is treeloader, which enables you to load in new tech trees, but as of now, not change them. Spica
23. ## [1.0.2] NovaPunch 2.09. - May 6th - 1.0 Compatibility Update

Tiberion, I have one question, what happened to the SLS first stage engine as shown in the lower left corner of the image on the first page, It was one of my favorites. If possible, would you please add it back into novapunch. Unless the download is only incomplete for me (how sad). Thanks for listening Spica
24. ## Think that your computer is bad because of KSP performance?

Same here, except mine is 4 years old, and a laptop, WTF is going on??? Furthermore, my old laptop gets a similar framerate even though it is 7 years old. Not to complain, which I would never do about this game, but this is VERY odd. Spica
25. ## Smallest stock SSTO Spaceplane (i think) + 1

Does it have to be manned to count, also, must we use jet engines?
