Spaceref has an article on the "Second Annual AIAA/NASA 21st Century Explorer Podcast Competition". This competition asks students ages 11-18 to make video and audio recordings on the topic "What do you think is NASA's greatest exploration achievement in the past 50 years and why?"
Details about the contest are here. It starts October 1. Prizes will be announced later. I thought the introductory video was interesting. It had a big-budget presentation on how to do the podcasts, and the students' low-budget ideas. It reminded me of the contrast between the typical view of a big government space program and a small private space mission.
