A nice summary! I've seen other write-ups of the specs and it's a phenomenal instrument design for a specific case of interest.

Now the pity would be if the Indian mission is the only planned Venus orbiter that doesn't include it and ends up being the first to fly, which it could be by a margin of years. If we have to wait ~15 years to get this data back, it will be a pity when it could easily be done within 4 years if Venus were a higher priority.

Just read the Russians gave agreen light and will send a new lander before 2023. Hoping to use some experimental tech to allow the probe to operate in extreme temperatures. Nasa is interested in helping develop this technology

I know roscosmos says alot and doesnt follow through. But Venus is definitely something they are capable of.

or at least they were capable of. I doubt that almost 35 years after the most recent successful Russian planetary mission they are retaining any of the know how

The Phase II Report of the Venera-D Joint Science Definition Team calls for a launch in 2026 at the earliest.

thanks for that. Glad I can count on this place to be accurate.

Yahoo later corrected the article to 2026. mad.gif

Man Russia needs a win so bad. The last somewhat successful interplanetary mission was....what ? ..Phobos II....somebody?

Phobos2 though unfortunately not fully successful, did get some great images, yet it seems to be the most recent Russian exploration mission to at least make it beyond Earth orbit. The most recent success seems to be Vega which after a couple of as-yet unmatched firsts in deploying landers and balloons to Venus, continued another first visiting Halley in 1986 according to this wikipedia page. After the breakup of the USSR, other than the Russian's fine and clockwork Soyuz activities and contribution to ISS, its unfortunately been crickets as far as exploration is concerned. It looks like Luna25 in 2021 is their next hope in a long line of false starts, found this article on the space review.

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.

https://www.space.com/possible-nasa-venus-f...ip-mission.html

This article discusses the possibility of a flagship-class mission to Venus sometime after 2023.
One may argue that recent Venus proposals have failed because they are too cautious, so perhaps a multifaceted
approach on the scale of Cassini would stand a better chance of success.
Mentioned are multiple orbiters, long and short-term landers, and a balloon-based aerial platform with, (sic) a seismometer.
Despite its ambitious nature, the proposal strategy seeks to be cheap relative to other flagship-class contenders.
I guess that means we'll have to wait a few more decades for a sample return.

Interesting timing, given that three Discovery proposals aimed at Venus are now being evaluated with an announcement of selection for Step 1 targeted for January 2020, only weeks from now. Any of those three would satisfy the flagship aims partially, so the proposal of a flagship mission puts some (more) people/programs at cross purposes, and the community has to have a lot of overlap; there can't be very many people who would be investigators for the flagship mission who aren't involved with some of those Discovery proposals.

Orbital studies of the surface and orbital/descent studies of the atmosphere are both addressed by the Discovery proposals, in addition to the descent imaging of tessera terrain. The flagship mission includes a lot more in situ surface focus.

The timing feels off unless the people proposing the flagship mission have a strong sense that the Discovery proposals are all going to be rejected. Otherwise, the flagship goals could descope and focus with the satisfaction of some of those goals.

I don't recall any precedent for gathering together several discovery-scale proposals with the same destination and consolidating into a single flagship-scale mission. But there could be some efficiencies in launch, data return, shared infrastructure. Politically it would be difficult to persuade the individual would-be PI's to report to a single overall head, but I suppose they might be willing to settle for a piece of the action with high probability, in place of a low-probability shot at being the sole focus.

Anyway, I am just imagining that; the article mentions no such consolidation. It seems to describe a top-down effort by someone who wants to design the whole venture from scratch.
