The producers of the science documentary 'BLAST,' about the launch of a high-altitude telescope, claim that they're the first ones using ArtistShare to raise money for a film.

ArtistShare is an Internet financing site, originally for musicians. Fans can either pre-buy a download or a CD, or donate larger amounts -- which might earn them a producer's credit, tickets to live shows, original hand-written sheet music, etc.

'BLAST' is being featured on the homepage of ArtistShare; donate $150,000 to the project and you'll get a hand-written thank you letter from director Paul Devlin, tickets to a private screening at the SoHo House in Manhattan, and much, much more.
