I've started a new blog on this topic at http://futureplanets.blogspot.com/
This blog supplements UMSF by allowing on topic discussions that include politics and other topics not appropriate here. The first entry is up with some additional news on the MSL funding and schedule problems. -------------------- |

Obviously, ZLD was joking slightly. But the question does remain, would larger-than-MRO-HiRISE telescopes be worthwhile in Mars orbits, or would they lose out due to atmospheric distortion? It looks like the equation for a diffraction limited telescope is pretty linear at this size, with doubling the resolution requiring double the mirror diameter. So getting 5cm resolution would require an ~ 3m telescope. Getting that into Mars orbit is left as an exercise for the reader. But a 1m or 1.5m telescope could be reasonably sent to Mars, giving 8cm resolution.
