Launch Base park
Launch Base is the space park. You build on Home Base, a small round world with rockets standing on its edges. Three other worlds float in space around it.

Rockets to other worlds
Build your track into a rocket's gantry and, on the ride, the cart rolls into the rocket and flies to another world. Keep building there, then take that world's rocket home to finish.
- Mars: red dust and a rust-coloured sky, with 0.38 G.
- The Moon: grey ground and a black sky, with 0.16 G.
- The Ring World: you build along a giant planet's ring, with 0.10 G. Slingshot rings on the ring push the train along fast.
Gravity changes the ride
Each world uses its own gravity on the ride, so the same hill feels floatier on the Moon than at home. The cart gets a launch as it leaves each rocket, so low-gravity sections do not crawl.

Carts

- Space Shuttle: yours from the start.
- Moon Rover and Hover Sled: unlocked by playing.
