starship-design: Planet Mapper on the Cheap

Hi Guys...

Here's another really interesting design... for very light-weight 25 metre
space-telescopes, a hundred of which would make up an interferometer cluster
and allow terrestrial planets to be imaged [10,000 pixel images] around
other stars... all for about $6 billion. Spread over ten years, and able to
do useful work from the word go, the system would make planet-mapping
routine, and could easily be in place by 2020.


this one really excites me because it could happen and it'd be cheap
compared with the hundreds of billions needed for a Planet Imager built the
usual way...
