The 6.5 meter James Webb telescope has been delayed. James Webb has 18 hexagon segments and weighs about 6500 kilograms. There are about four ways 1000 meter (kilometer) scale space telescopes could be made in the next two decades. 1. Space bubble telescope 2. Self-assembled modular telescopes 3. Spider-fab in space construction 4. Giant lunar space telescope construction Space bubble telescope Devin Crowe gave an update on the NASA NIAC study on one-kilometer
