Something wasn't adding up. How could the telescope be more than three-quarters complete after $3.5 billion, but require more than double that amount to finish it? Also, how did the launch date get bumped by three years, to 2018? And how did 6.5 billion become a disastrous $8.7 billion so quickly? So I did a little digging around, and perhaps a little investigative reporting as well, and got ahold of a Webb Project Scientist who's also a member of the Webb Science Working Group.
