Once you have spoken to the Astro Zone manager and built your new ship, there is no reason to go back there. If you leave the island anytime after building a new spaceship, you will find it parked on top of the castle in Arturus.
Once you fly Excalibur to the Pewter Moon, you build a new space ship there. Talk to the manager at Astro Zone and he will let you use the holo-pad to build one. From there, you can fly to the three planets on the list that the Queen gave you (Jungle, Ice, and Fire). If you do return to Arturus, your spaceship parks on top of the castle.
You can't, if your stuck your stuck
where is the boss on pewter moon poptropica

pewter moon
If you got the spaceship on the Pewter Moon, and you are back in Arturus, it should be parked on top of the castle. If you are in space, deliberately crashing the ship will transport you back to the Pewter Moon. (The only other way off the planet Poptropica is the saucer. If it's gone, you are stuck.)
You can try costumizing when you are on the Pewter Moon, or buy one from the Poptropica store.
you can just fly back
The planet Poptropica has the same coordinates as the Pewter Moon : X-56 Y-52.
To get there from Arturus, the coordinates are X-56 Y-52. These are technically the coordinates for the planet Poptropica, around which the Pewter Moon orbits.
all you have to do is go on the space ship you made in pewter moon and move to the cordinates 15 15
Fly to Pewter City then walk right and follow the path to Mt. Moon.
