Ok, so I believe this is a great start I think it needs two really drive it home. One I think you should add a distance line and how far a route should go. Giving the player the ability to know how far the planets are from the station and the maximum length mix this with a telling the player what resources are going in and out and these can a great QOL tool. And two is to add events for example your "space station had a vacuum leak and lost some personnel the workers have gone on strike removing some available ships." This was an example but you should make some good and bad events it would be even better if you let the player choose which events to participate in giving the player freedom of choice. Overall a very relaxed experience and I hope to see a continuation of this game in the future. Happy Programming!
