Northrup Grumman needs to go bankrupt
If I had a contactor quote me 500, then ultimately try change me 2000, he wouldn't be getting paid. AND overrun the project by 14years! Come on!
I have no experience in building satellites, but I am an engineer, and I can see quite clearly that the chances of that solar shield deployment working successful are close to zero.
For the money they've spent on web, I bet we could have built a reliable telescope in LEO - similar to how we've built the ISS - then gently push it its L2 operating orbit.
