I'm new here so sorry if my formatting sucks but I was wondering how rocketry and orbital mechanics would work on a ring world?
I was thinking my ring world would be 1 AU in radius, 80,150km in length. I haven't decided on the thickness or the mass yet.
The ring would generate gravity by spinning. According to Issac Arthur's Ringworld it would have to spin at 1200km per second and rotate once every 9 days.
There will be a sun identical to our own in the middle, and an inner ring somewhere in between the main ring and the sun. The inner ring will control the lighting, day night cycles, the climate, pretty much anything to do with the sky.
What I want to know is how would a civilization native to the ring world utilize rocketry. Would it be useful to travel within the ring world? How would the gravity of the sun affect the trajectory of rockets making trips between two different points on the ring world?
Would it be possible to launch stuff into orbit? If so, what would that orbit look like? Could you make an orbit for a sattalite to map out the entire ring? Could you make something orbit around the ring like a moon?
Also what happens if someone builds a rocket and goes 1200km per second in the opposite direction of the ring world's spin? Would the rocket fall to the sun?
Sorry if this is not the format people usually ask questions in, I'm new here
