This was followed in 2006 by the third "mission", Space Mountain: Mission 3, an indoor Spaghetti Bowl coaster.

In 2017, Bruce McKechnie announced that a mysterious building being built in the area with the then-three Space Mountain "missions" was to house a RMC Steel Raptor Track single-rail coaster beginning with the 2018 season.
