I saw an article on Slashdot about a competition NASA sponsored to design a better space suit glove for use in space walks. I found this pull quote from the Discovery.com article of interest:
NASA turned to cash-prize competitions in an effort to solve some of its technical problems with low-cost, innovative solutions.
This is very much the model advocated in the Wikinomics book I just read recently (see prior commentary). NASA's approach to opening innovation on the space suit glove supports the open innovation Ideagoras presented in the book.
