Actually that's a lot less folding than I thought. I had assumed with all of those separate mirrored faces that there would be more than two folds of the primary mirror. That said, Ican't imagine how they are possibly going to align those two pieces during deployment with the kinda of microscopic tolerances that will be required. The rest of the deployment looks fairly straight forward. But certainly the nature of its deployment is extremely high risk in such an expensive project.
