Wow, toutatis, you've come a long way! From starting out with basic untextured models, to making your own missions with their own trajectories!
Thanks SpaceFanatic64.... Well, basic knowledge of space flight mechanics helps me plan trajectories... and I also space fanatic and I wished all my life to work in organisations like NASA, but I live in a not right place... such plans and dreams can't come true here...
Also, wasn't the next mission supposed to be a Pluto orbiter, and then the one to Mars?
am sorry, but I still don't decided how to reach Pluto if make a launch this or even next year... still several years it impossible to use gravity assistance of Jupiter, Saturn to reach Pluto system faster as possible... but without a gravity assistance it will be too long time way... if I will use a lot of fuel to reach a big velocity during start from Earth, it will be hard to reduce velocity to go into orbit of the planet due to lack of sufficient fuel... all mission I plan, can use only engines as in real space technics...
but in Celestia we can go on a journey through time, and that is great thing...
I will try to make mission to Pluto but later...
