I accidentally replaced the Tour of Jupiter scenario's information with a landed DGIV. Can anyone tell me how to write orbits into scenarios? Otherwise I always get floating ships with eccintricities of 1.00
You can use Scenario Editor after you have launched the scenario. Write in a SMa to 1.5 planet radis, and an eccentricity of 0, and you should be in an circular orbit around the planet.
Write 0 in the box and press apply. Edit: make sure to set the SMa so that you're not on a suborbital trajectory (that's a path which crashes into the planet at some point). I've had problems with those, but YMMV.
