I've a bad feeling about the James Webb, the deployment is SO complicated, it really makes me wonder if it was the best way to do it. Naturally not being a NASA engineer my opinion is worthless, but to the space "layman", I wonder why it could not have been launched into Earth orbit, test "deployed" with all the bits, then somehow shot off into the lagrange point after verification everything was OK.
It is a monumental risk. Fingers crossed though, as it will be the best insight mankind as EVER had in the history of civilisation.
