How do I travel between planets?

[Auron]

I have the platform fitted with turrets, thrusters, fuel, and oxidizers. I also have the "Vulcanus discovery" research completed. But how do I actually travel to a planet? Im on the space platform but I dont see any button to activate the thrusters.

The space map doesnt seem to give me any options to actually travel either. It just tells me what to expect during the travel.

Click on the main "building" of the platform, it will allow you to set a schedule like for trains.

Your Space Platform is a train. Just click on the main building and then on the right side should be a box where you can set up a schedule. Just select Vulcanus and it should start moving right away. Just make sure that you delete Vulcanus afterwards, otherwise, if you just add nauvis later on it will endlessly cycle between them.

Update: I figured it out.
Its in the main space platform hub
