In order to ensure structural integrity and longevity of the Space Mountain track system, it is rumored by Screamscape that the coaster track has been re-adjusted and modified. New cross bents are replacing old ones that are attached to the supports. Many of the supports are new as well.
The repainting of the lift hill rocket has also taken place. We also will see new blue exhaust ports. It will be interesting and fun to hear reviews on the soon-to-happen soft opening, rumored to occur within a week's time from now.
