Oh well, might as well start that new topic since it's already well advanced in the Juno area...
My perspective on landers is as follows. All the landers we've had so far were dropped blind onto an essentially unknown surface. Any future landers can be targeted for specific terrains. It really is not true that we have had representative landings. Even a descent image or two, a panoramic photo plus a bit of surface composition, from a simple Venera-class lander just updated a bit, would be useful if we could put several down at well chosen targets. My choices would be: Examples of the main plains units (smooth, fractured, ridged) tesserae high elevation radar-bright tesserae large fresh lava flow unit ('fluctus') crater dark parabola crater ejecta outflow unit dunes area. And I have always assumed, rightly or wrongly, that it would be relatively easy to put these down, so they ought to be fairly inexpensive as planetary landers go.

Aha! I always wondered why Madame de Pompadour came up with that ridiculous hairdo. She was hiding her TARDIS in it!

Bob Shaw So what exactly was the purpose of those Police boxes in the UK? Kind of an exclusive telephone booth for cops? I watched Dr Who for years and never understood that. |

Yes - from the days before portable radios (they were designed in the 1920s). UK Police also carried whistles with a very distinctive sound, to call for aid (I always wondered what stopped the guys in the black hats getting hold of whistles in order to confuse matters, sorta like a 'whistle gap'!). Officer Dribble, er Dibble, in the classic Boss Cat cartoon show had exactly the same thing, but in his case it was just a phone in Top Cat's alley.
