Drat, they didn't say that in the tutorial. Now I'll have to travel back to Sol, that's 11 hours to go and another 11 hours to come back

Hi there everyone! I'm BlackEagle.
I started to play the tutorial, then had to start over.
Since yesterday I'm stuck on Task 2 of Step 19. Deploy a station in the orbit of the planet / moon / belt.
I could use some advice please. When I click on Ship-Cargo, there isn't any Station to deploy.
