Giving Birth to the James Webb Space Telescope: Part 2

The ASP concludes its inside look at the James Webb Space Telescope (JWST) with the second half of a two-part Astronomy Beat. In the previous issue (110), John Mather described the early days of the Webb project, including budget constraints and the challenge of designing an observatory that was completely impossible to build withold technologies. Now that the instruments are mostly complete, John looks at what remains to do prior to launch.
