Space seems to always be a popular topic on HN, and I wanted to share a project I've been working on for the past few months at NASA: The International Space Apps Challenge. It's a global space hackathon happening in 75 cities around the world on April 20-21, 2013.

We've put a lot of thought in to how to make Space Apps different from most hackathons. We've worked with scientists throughout the agency to produce over 50 seriously compelling and detailed challenges (http://spaceappschallenge.org/challenges) to serve as inspiration for projects, and we have a huge focus on international collaboration between events.

Anyway, I just wanted to share Space Apps with HackerNews and see what you all think. We're really excited to work with people around the world to improve life on earth and life in space and hope to see you all there!

PS: Astronaut Ron Garan is currently doing an AMA on Reddit about Space Apps as well - http://www.reddit.com/r/IAmA/comments/1ajgje/i_am_astronaut_ron_garan_last_time_you_told_me/
