How hard would it even be to get a sample and return it back to Earth?

First you would need something that passes through Venus without melting and also be fast enough, so the pressure doesn't kill it.

What next?

They probably could if they shield it enough for a couple good photos before it dying for whatever reason but I’m sure there are things besides microscopes that can do analysis other then sending it all the way back. I’m not a chemist but I know there was missions to Mars where they scooped the dirt on Mars and did chemical analysis on it and did a bunch of experiments with it with a probe. There are probably many different ways to detect life definitely if we know the processes it uses to produce shit.

I’m sure there will be a bunch of schizos who will rage about inner workings of the probe (Without really knowing much about it) how it might be faulty or some shit. It’s literally the easiest thing to do we have all the technology and rocketry to do it right now with one mission. Also probably can still use some sort of microscope to get pretty pictures. Although I’m don’t know if there were similar probes that also used a microscope so that maybe new. Still easier then having a return mission. Suicide probes are always easier.

obviously we cant have certanity because something like this never happend before
but on earth more often than not when you introduce foreign species to an ecosystem it completly wrecks the ballance and often leads to ecological catastrophe of varying size

if all those extreme conditions are not essential for microbe survival it could be REALLY bad if we brought them back

Alternatively you just have the probe do all the processing and send the results back to earth. Then you could have drones repeat the mission for new samples.

which means it’s literally fucking impossible for them to live on Earth as nothing even CLOSE to their habitat exists here. There is absolutely no chance that something adapted to Venusian clouds could live on Earth. It’s hard to emphasize how extreme the difference in environments is.

There's no way sample return from Venus is happening, maybe you could scoop something up from the very upper atmosphere but that's probably not going to be very useful.

A sample return mission using a rockoon. Like pic.

The rocket will contain a sample collection payload and float around collecting samples, when mission is completed the rockoon will jettison the ballast and rise up above most of the atmosphere to avoid delta v penalty, then the rocket will release from the balloon and fire taking it to orbit, either rendezvousing with a waiting spacecraft or continuing on straight to Earth, optional is leave a small science payload behind on the balloon for further science.
