The concept is good and the art is cute. The gameplay itself is....shaky, though. There's currently no visible reason to not just send every ship to the closest station of an appropriate size. The direction the ship faces appears to be irrelevant, and there's both too much and not enough inertia (it's in space, so there should be nearly friction, but it's also far too slippery for non-zero friction) There also appears to be (at least as far as 5k weight) essentially zero risk of failure as long as you're remotely competent.
The player's ship also unfortunately becomes utterly useless except to stall starvation very quickly. Which leaves the player just idling, doing basically nothing except building more ships.
This feels mostly like a balance issue, though, at least. Making it so there's a reason to use several stations rather than just one medium and one large would encourage the player to keep exploring. And it just needs some appreciable risk of failure before becoming planetary that isn't trivialized by building 3-4 ships
