Just read the question...

I think you mean:
how do i get the space magic pin quest? i want to go to the inner space shop.

Answer:
First you have to do divers quest, than drivers quest, than space quest in space mountain quest deck.
than you go to the bottom right door.
use space magic and go to the far left exit in the space area, and go into the rocket ship and you are there.
