"This year's challenge is: Help NASA to increase the number of corporate researchers, university researchers, entrepreneurs, and investors who utilize the Nation's investment in spaceflight to grow their investments in knowledge and commerce.
Specifically, participating teams will compete by designing and preparing a NASA Spaceflight Promotion Plan and illustrative flagship promotion projects including a fully implemented Internet Solution with a 20-second promotional video and other concept design/media elements".
