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.

Is there any info on whether mission planners expect or need the Davinci+ descent probe to survive on the surface for any length of time?
The mission CGI is amusingly coy on that one as the probe disappears behind a rock! Obviously we are talking about minutes not hours considering the conditions there, and yes, I know that imaging on the surface probably wont happen if the probe lands upright (the imager being on the underside i think), but what about the other instruments? I guess I was hoping for a Huygens-like surface surprise. Presumably there are limits on how long the orbiter and probe are in line of sight too? P |
