Lest we forget - it was originally planned to be launched in 2007 !

Wow - I just commented about the further delay on a Facebook post on the subject, and got a "why are you commenting, you're not even American" reply ! Had to point out that it's planned to be launching on a European Ariane V

The year is 2101. Fusion power has become widespread. Self-driving cars are common. Humanity has a colony on the moon. The JWST is set to launch in 2102....
