This topic was discussed recently on sci.space.tech.
One of the problems identified for heavier than..
atmosphere craft was the *runway length required
to take-off or land.
[ And to those that would jump in and suggest
keeping it aloft continuously, that is impractical
with sandstorms, ..even assuming you could squeeze
a 'little' RTG into it, and still get it off the ground. ]
Balloon, or better still, orbiter with a bloody
good telescope. No dust, no sand, no runways
to deal with and you can cover far more area.
* Well, of _course_ they would be using all
those really _long_ runways built on Mars
during WWII. ;-)
