It's a decent little update. My problem is that this kind of update should be done like every five years instead of like every fifteen years. I'm generally a fan of Mission: SPACE, it's no Horizons but I feel like they at least made a worthy attempt to create a new pavilion true to the EPCOT Center spirit but for modern audiences.
I was excited to hear that they were updating the pre-show, especially that it will ever so slightly more promote diversity. And I was certainly happy that it was finally going to be in HD. It drove me nuts from day one that they had these (at the time) fancy new HD monitors but a clearly standard def image.
I do think Gina Torres somehow falls even more flat than Gary Sinise. He never seemed like he was putting huge effort into it, but actually showed some halfway decent enthusiasm every once in a while, and certainly made the "don't move a muscle" line amusing. Gina Torres just totally lost me once I heard her take on that line, there was not even a hint of humor or any kind of emotion at all in her reading.
I'm glad they've made it more accessible to little ones, even if it's not really that huge a height difference. You never know what kid will have their imagination triggered in a big way by this, have their mind blown open by the experience and become inspired to work for NASA or SpaceX or even become an astronaut when they grow up... and that's really what the park should be all about. The new Earth/Green Mission is certainly well tailored towards kids so that it's not too overwhelming but there's still an element of thrill to it.
Mars/Orange looks great, of course. I appreciate all the new little details like the futuristic new satellite and space station in Earth orbit. It occurred to me this time that it's kind of goofy that NASA wouldn't turn your butts around back to Earth as soon as they saw that meteor shower approaching Mars. You certainly wouldn't want to even be on that planet with all those big rocks probably about to rain down on the surface.
All of the various new music around the pavilion is nice, although not as strong thematically as the original score. I appreciate they kept the exterior BGM and the score for the Mars mission, I just wish they had re-orchestrated it so that it doesn't sound so synth-y. Count me among those that are glad that they mercy killed Destiny, although I wouldn't be opposed if there were a little snippet of it of it somewhere, just not blaring on loop in that endless exit hallway. Speaking of which, still super annoyed that that hallway looks like something Kennedy Space Center would do in the 1980s rather than something Disney would do in the 21st Century.
Overall, big net gain here, just wish this was something Disney was more regularly doing with all of the Future World pavilions, it's very much in the spirit of how the pavilions were originally meant to be updated over the years.
