After more than 20 years of planning, development, near cancellation, blood, sweat and tears, the construction of the James Webb Space Telescope is complete; it was was just completed. It took seven years longer than it was supposed to and went seven billion, two hundred million dollars over budget. But in the end, everyone is going to be glad that NASA, et al. stuck with it.

The James Webb Space Telescope is one of the most remarkable things mankind has ever built. Over the last seven or eight thousand years, mankind has built some pretty remarkable things; temples, pyramids, religions, the printing press, the United States, the SR-71, the Ferrari 250 GTO, the Saturn 5, the internet, etc. The Hubble telescope is one of those things, and not too far from the top of the list. The Webb telescope is its successor, and a worthy one.
