The source doesn’t say that this is something that Disney is actually planning to do, but rather suggests that it is peripherally on their radar as an attraction that is not well liked and could be an option for removal. Personally I’d love to see it go. It’s unpleasant, outdated, and doesn’t have a draw. There’s no ‘wow’ moment that the other rides have. It feels like a tight, claustrophobic simulator that was built in 2003.
It also lost its originality with other rides that do the same exact thing but better. Guardians right next door serves as a vastly superior space flight experience. Smuggler’s run also takes the ‘drive your own spaceship’ idea and does it way better. I’d even argue that the realistic flight deck feel can be achieved right across the way at Soarin. Mission Space serves no purpose now other than to be the posterchild of the clickbait articles about ‘scary Disney rides.’
I do wonder if a new and updated version of Horizons could be an option to replace it down the line, seeing that Horizons has become more and more popular in recent years due to the internet. They replaced universe of energy with an intense thrill ride, and although I like guardians more than energy, it does leave World Discovery pretty lopsided, as Guardians, Space, and Test Track are all quite intense. I wonder if this is their sign to do a reverse-guardians, and replace an unpopular thrill ride with a modern family attraction.
A new Horizons could serve as the centerpiece of the ‘new’ Epcot, because the park, especially its new vision, lacks a thesis attraction. Epcot currently doesn’t have an attraction that represents what the whole park is about, old and new. What better way to do this than with a new and improved Horizons? A park about the future needs to have a way to see what the future could be like!
They could demo Mission Space and build from the ground up, or they could even gut Mission Space and use as much of the current building as possible, maybe with a slight expansion out of the back. What works perfectly is the space restaurant, as it takes you to the Centauri space station FROM horizons, so nothing at all would need to be changed!
