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.

Moderators: I obviously had problems editing my previous reply and don't see a post delete button (sure I'm just missing the obvious). Please delete duplicates.
This is the correct link for the other poster at the recent VEXAG meeting for a mission concept that would go beneath the clouds for a more detailed examination of the surface. Venus Corona and Tessera Explorer (VeCaTEx) Mission ConceptVisit My Website: Investigating the Surface of Venus from Beneath the Clouds [#8031] VeCaTEx would use an aerobot to descend repeatedly beneath the dense clouds for imaging targeted area of the surface in the near infrared spectral region to address six of the prime investigations prioritized by VEXAG. -------------------- |

As a non-mechanical engineer, I nonetheless share antipode's sense that a cable more than 20 km long seems to introduce some serious worries about practicality. I can't even picture something like that working on Earth, much less being transported to Venus.
Here's an informative analysis of aerobot architectures. I'd never heard of nor thought of some of these architectures. https://dartslab.jpl.nasa.gov/References/pd...TitanVeinus.pdf We are, apparently, about three months away from finding out whether Venus will prevail in the upcoming Discovery mission selection, and the ESA decision on Envision was said, in 2018, to be expected "in 2021." So the next few months will have profound impact on the course of Venus exploration, with anywhere from zero to three missions in the balance depending on those decisions. |
