Ferris Valyn had some prize-related comments in a couple recent posts at Daily Kos:
Senator Obama, bring back the National Space Council - Here's one reason Ferris advocates for the NSC:
In addition, as we move further into the 21st century, the likelyhood is that we will have better and greater access to space, and there are resources in space that can help us deal with the problems we face, here on earth. For example, ProSpace, the citizen space lobby, has called for the establishment of large scale cash prizes that will help to develop the technology and systems needed to grow the private space industry. The NSC could be the instrument that is used to establish those prizes.
