Star Wars: Rogue One - 13 Things You Missed In The Teaser Trailer
6. Moisture Vaporator
This new Stormtrooper - a Shadow Trooper or a Death Trooper - dominates the shot, meaning what's behind him isn't the thing you're going to be looking at first time around.
On closer inspection, though, it appears to be a moisture vaporator. Used to capture water from the air, its presence indicates a moisture farm, such as the one owned by Owen Lars in Star Wars.
This isn't a desert planet, so it's a little stranger to see one appear here, but it means we're probably going to see another farm getting destroyed, and if nothing else it's another nice little nod to the original film.
