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.

new Wired article on the LLISSE is interesting once you bat away all the adverts.
The 20cm cube is designed to stay operational for 60 days capturing day/night transition, but likely have no camera, is hoping to hitch a ride on Venera-D. Also found an old PDF and another older? paper mentioning a possible wind-powered battery option for demonstration in 2023. Wind speeds are so fast at altitude it speeds the planets rotation by 2 minutes per day, wind slows at the surface to apparently a few km/hr so seems workable, solar cells should be considerably less mass but im not sure what the status is now though ive also heard due to high albedo Venus actually receives less energy at the surface than Mars does.. here's more fun. |
