A clever new telescope design could allow engineers to pack larger folding space telescopes into smaller spaces on rockets, dramatically reducing their weight and launch costs. Inspired by amateur telescopes which can be disassembled for transport, this design could allow fleets of low cost space telescopes with bigger mirrors than Hubble. They could be used for detailed Earth observation, astronomical observations, or even be sent to other planets and moons to examine their surfaces in extreme detail. Link.
