This is my second post here, and I was brought here because I am currently using Universe Todays news feed on my website ( http://www.moonport.org )
I noticed that there are no threads mentioning the Orbiter Space Flight Simulator ( http://www.orbitersim.com ), so I figure I'd mention it before someone else does. :P
Does anyone here use this simulator? I find the learning curve is very steep, and when you finally successfully launch a probe to another planet, you will get a real deep appriciation of the work and math involved. It's not easy.
Hope to hear from from other Orbiternauts here.
