Wired has similar conclusions of NASA problems

Wired has an article by Gregg Easterbrook which discusses the problems of NASA I mostly agree with his analysis but his 4th place recommended priority Figure out a way to replace today's chemical rockets with a much cheaper way to reach Earth orbit should be first.

I also believe that laser arrays (preferrably with mirrors), magnetic launch systems (coilguns, magnetic rails, magbeam for orbital boost) and tether systems are the technologies that should be pursued I believe that the laser arrays take advantage of the rapid improvement in lasers. Solid state lasers that had less than 15 KW of maximum power in 2003 will have about 100kw in 2007

The space review also has an article indicating the importance and need for space based solar power However, I believe we can skip the development of lunar mining by using te simplified construction methods of inflation of structures (magnetically or with gas) and formation flying. This allow for simple but large thin film structures to be fully constructed on earth and launched and deployed in orbit.
