Hi, Jose! To the best of my knowledge, there has been no change to the track formation on
Space Mountain. Since the refurbishment, the changes I noticed were:
-Interactive games were added to the Stand-by line
-It might just be me, but it seems a bit darker on the attraction
-A sound system was recently added. It adds something to the experience!
-As you exit the attraction, the walls were painted and there are some different displays
Overall, if you did not know that Space Mountain was closed for refurbishment, I am not sure you would notice any of the changes. That said, it is still an amazing attraction as you "zoom" into space! Enjoy!
