When I got the TED talk summary for this week, it seemed valuable and I planned to send it along for the blog. But after watching the talk by spacecraft engineer Nagin Cox, I think it is better to just concentrate on her talk. It is about lives lived here and now on Earth can appropriately be considered "bi-planetary". You may have heard of "bi-coastals", people who live on both the Atlantic and Pacific coast by flying back and forth for business reasons. This 14 minute talk is about being professionally bi-planetary. It is definitely worth watching.
