Which mission would get a 1000 Km resolution map of an extrasolar planet more easily?:
A) a space telescope to the sun's gravitational focus
B) a hypertelescope
A consists of just one space telescope, while B consists of bajillions (technical term :-)) of space telescopes positioned precisely. On the other hand, A has to get hundreds of AU away, while B might be placed in the Earth-Moon L5 point.
