This document is the first one I've seen (from any Presidential candidate) that specifically promotes space prizes. Here are the 2 excerpts:
Jumpstarting Consumer Technology: Obama will expand the use of prizes for revolutionary technical achievements that can benefit society, and funds for joint industry/government rapid-to-the-consumer technology advances.
Establishing Teacher/Researcher Fund for High Schools: Barack Obama will support nontraditional approaches, such as student design competitions and internet-based collaborations to engage students and develop the next generation of scientists and engineers.
