I'm not sure this is really a good fit for a Kickstarter project. I love rockets/space/science/etc and fully support researching cheaper launch methods, but for most people to invest, they want to get something back. There are very few people who will/can donate to something on a purely altruistic basis. These guys aren't a charity and I can't even get a tax write-off. Pushing a button, while cool, is not really a return on investment and only rocketry enthusiasts with extra money (a rare combination) will be willing to pay for that. The cheaper reward tiers offer a "Master-Class on 3d printing and rocket science" which will have more backers due to the 3d printing information but probably not enough to clear their goal.<p>I think a better way to spur investment would be offering a reward tier that gives a portion of the company (i.e., a $x investment gets you a y% stake in the company). This is just selling stock in a company off of Wall Street and probably a better fit for a company that isn't offering services or a physical product to the general public. I'm not sure what kind of regulations you have to follow (or if kickstarter would even allow it) but it would certainly open up the field of potential backers to include the folks that know/care nothing about rockets but would like to make some money when the company is inevitably bought out by a larger space launch company like SpaceX.
