Here's the blurb about the show from ANN about what the show is --
Welcome to THE SPACE SHOW tells the science-fiction story of children who experience a space-spanning adventure. The story will begin in the countryside during the summer vacation of fifth grader Natsuki Oyama. Natsuki just moved here in June, and she and four of her schoolmates are about to embark on an adventure together that will take them beyond the fields they call home.
Sounds awesome right well it's even more awesome because it's from the creative team behind the R.O.D. TV series Besame Mucho so you know it will be interesting and not just for the awesome eyecandy on screen. And that eye candy on screen looks freaking amazing from the trailer hopefully it'll live up to the hype and hopefully when this gets released on DVD we can get a nice sub of it while we all what for someone smart enough to license it for America.
Anyways I predict it will make the rounds of the big US Anime Cons but the rest of us won't get a chance to check it out until it goes to DVD well into the fall so until then you can enjoy the trailer below. I'm really hoping I'm wrong though so we can all get a chance to see it sooner.
