1. ## Can someone explain what specific impulse means?

An ISP of 1 means that if the engine produces 1 N of thrust for 1 second, it will burn 1 kg of fuel. An ISP of 500 means that if the engine produces 1 N of thrust for 500 seconds, it will burn 1 kg of fuel. Modern rockets have an ISP of anywhere from 250 to 400 ISP.
2. ## Post How You Found KSP

This thread posted on Orbiter-Forum. It announced the first release, 0.7.3
3. ## How old is jeb?

Slightly more than 33200000, in SI units.
4. ## Post your stupid mistakes

When I did all my calculations in smoots (~1.7 m), slugs (~14.6 kg), and seconds. Another is confusing m with mass. Ended up with an energy instead of a velocity...
5. ## Ugh Spaceplanes

Universal Grappling Hook (UGH) equipped spaceplanes are currently not possible in KSP.
6. ## TWR vagaries...

4.217 m/s^2. Then, when you multiply by x s, you get a speed in ms/s^2, or just m/s.
7. ## mun Geo stationary orbit

A Munostationary orbit, which would stay over the same spot on the Mun\'s surface, is impossible. You would be captured by Kerbin.
8. ## Is it possible to get an orbit that looks like this?

It\'s possible to make an orbit look that way in 3D space, however if constained perpendicular to the reference plane, then no. Images make more sense.
9. ## How hard is it to land on mars?

It\'s hard enough if you assume that everything will work. If we have learned anything from previous flights, Murphy likes to hitch a ride on spacecraft.
10. ## Happy Birthday KSP!

The first KSP beta (0.7.3) was released on June 24, 2011. It\'s amazing what\'s happened in just a year.
11. ## [Suggestion] Multiple bodies of gravity have influence on ship at the same time

Implementing 3 body solutions in the Kerbin system would destabilize any orbits. The force of gravity F = mMG/r^2. F = ma, so ma = mMG/r^2 Solve for a is easy: a = MG/r^2 Plug in the values for the Mun: a = (9.76e20)(6.67e-11)/(1.2e7)^2. The acceleration caused by the Mun is approx 4.52e-4 m/s^2!! That is a dV of 1.627m/s per hour in LKO, or ~0.07% of the total orbital speed. To compare, earth\'s moon only exerts 0.119 m/s dV per hour, or ~0.0015% of total orbital speed. Munar orbits are even more unstable because of Kerbin\'s influence. Also, that 0.07% is significant. That means your entire
12. ## This is so unbelievably Kerbal I had to share it with you...

I can laugh at little green men on my screen doing this. Knowing that there were real people doing this dampens the humor considerably.
13. ## How far has KSP come?

KSP\'s release on Orbiter-Forum Orbinauts received the game well, but read the first few pages of comments. Bug reports galore! KSP has come a very long way.
14. ## How did you get into KSP?

June 24th, HarvesteR posted this thread on O-F. Tried it, still play it. It nearly cut my Orbiter time in half.
15. ## What would you have wanted to know when you were new?

I remember the days of 0.7.3. There was no SAS toggle. :\'( ??? I would have liked to know that our only instrumentation was the navball. Orbiter spoiled me there.
