Op-Ed: The new space race: It's not just the U.S. and Russia anymore
There are now many space programs, both national and private. And that's good for science.

Posted by Louis D. Friedman on 2013/12/13 12:05 CST | 7 comments

I once argued that the concept of a space race represented old thinking. The modern way forward in space would be through international cooperation and coordination. Today, I think my insistence that the space race was over was naive. There are now many space races.
