Space Telescopes at 550 AU can image exoplanet surfaces down to 1 kilometer resolution

Space Telescopes placed at the gravitational lens points of 550 AU can image exoplanet surfaces down to 1 kilometer resolution. This would be like 13000 X 13000 pixel images of the earth. 169 megapixels images.

Mason Peck talks about the Breakthrough Starshot project.

When we achieve good interstellar travel (20% of lightspeed with good unmanned acceleration for laser pushed sails) then we get various spinoffs.
* go the moon in 6 seconds (unmanned laser nanosats)
* go to Mars in one hour
* Travel to the Gravitational lens point (550 AU or 550 times the earth to the sun distance) in two weeks

Very thin materials for 1 gram chipsat sails could make them 4 meter by 4 meters. They would thin sheets of electronics and sensors. They could survive several impacts. Also, by sending 1000 chipsats (repeatedly launching mass produced sails, one a day for three years) then statistical several should survive to reach the destination.
