Looking great!

My advice would be to delay a Kickstarter until you can really show off your project with some detailed preview of the gameplay (which is hard given that it means you have to go a long way through development first). Right now there is a small crowd of space games in Kickstarter, and even though they got covered by some major websites such as Rock Paper Shotgun, they seem to struggle a bit gathering funding (some of them aimed at really high goals such as $200 000...).
But if you ever start a Kickstarter campaign, you can count on me to back it up and spread the word!
