Terraforming Venus is a bad idea, though not impossible

Lots of problems left, including the 117 day long "days". There are books on
this subject, but I can't find a referance at the moment.

This is probably the biggest problem. AFAIK we do not have plant or
animal life that can live with days that long, and the human psyche
is not up to it, either.

I am still of the opinion that the most livable places in the solar
system are those where the length of a day is at most 50 hours, any
more than that and life gets upset.

Building greenhouses on Mars or even asteroids is probably the easiest
way into space. Lots of sunlight, in intervals short enough. We know
how to build greenhouses and a cubic kilometer of ice and carbon should
be enough mass to compensate for a slightly unbalanced biosystem, for
a very long time...
Diatoms do not get upset about too long of day, and I do believe the
solar spectrum worth of 400~450 nm is getting sufficiently into and even
somewhat effectively through them relatively cool clouds of Venus.
Diatoms should very much like photons of 425 nm.

There's sufficient buoyancy as to sustain a Venus form of
advanced/mutated diatom as flying much like a micro rigid airship,
either by having a lighter gas (perhaps H2) interior or perhaps just a
sufficient amount of vacuum could make such a silica diatom quite
aeromatic, especially if there's sufficient winds aloft as to help
promote that flight of such micro silica airships.

Speaking of "Terraforming" the likes of Venus, of which I believe this
notion is way outside of even the most advance human capability, not to
mention the terawatts of resources. However, as per terraforming our
moon isn't such a bad nor insurmountable notion.

Terraforming the Moon; this notion is merely pulverising it with a few
tonnes worth of dry-ice(CO2) per year, plus a few other heavy elements
(radon if need be) that'll stick around long enough to create a usable
terminal velocity(Vt).

Once able to access the moon via conventional methods of reentry and
deployments, then we're into the hollow rilles and/or geode pockets for
a little personal protection from the lunar surface environment that'll
need some further work before it's breathable (if ever). At least
robotics well become affordably doable and thereby enabling the next
logical phase of helping to establish the LSE-CM/ISS lobby or base camp
abodes.

There's a couple of slight details that'll need your expertise, and if
you need some ideas and/or notions as to what those might represent,
just ask and you will receive.
