Hey what is Orbiter Simulation?? I mean other thatn the obvious that it is a space simulation. Is it good, bad, ugly? I guess i would like a brief review please. On a lighter note is it just me or do i put nothing but questions on here??? I will try to limit these.

I haven't tried it myself, but have read nothing but good things about it. It is supposedly very realistic and thus will take you some time to work through. But the good news is you don't have to just trust another person's word for it. It can try it out yourself. The author makes it freely available here:http://www.medphys.ucl.ac.uk/~martins/orbit/orbit.html

Thanks i will try it

Thanks i will check it out.

I recommend you go to www.orbitersim.com and read about it there. There is also an active community in the forum there.Personally, I love orbiter. It is quite faithful to real (Newtonian) physics.
