NASA consistently does good work in AI. I've blogged before about the Earth Observing Satellite project. There was autononmous fault diagnosis on Deep Space One, and the project to organise ISS astronaut's daily schedules. I've heard from my friend Simon Thompson that there's a very impressive NASA paper at the AAMAS industrial track this year. Now they're installing speech interfaces on the ISS, as astronauts have trouble holding a printed manual and performing complex maintenance tasks while floating about in microgravity (no kidding!). Cool stuff.
