Rocket Lab Will Self-Fund a Mission To Search For Life In the Clouds of Venus (arstechnica.com) 32
FallOutBoyTonto shares a report from Ars Technica: Never let it be said that Rocket Lab founder Peter Beck lacks a flamboyant streak. [...] On Tuesday evening Rocket Lab announced that it will self-fund the development of a small spacecraft, and its launch, that will send a tiny probe flying through the clouds of Venus for about 5 minutes, at an altitude of 48 to 60 km. Beck has joined up with several noted planetary scientists, including Massachusetts Institute of Technology professor Sara Seager, to design this mission. Electron will deliver the spacecraft into a 165 km orbit above Earth, where the rocket's high-energy Photon upper stage will perform a number of burns to raise the spacecraft's orbit and reach escape velocity. Assuming a May 2023 launch -- there is a backup opportunity in January 2025 -- the spacecraft would reach Venus in October 2023. Once there, Photon would deploy a small, approximately 20 kg probe into the Venusian atmosphere.
The spacecraft will be tiny, as deep-space probes go, containing a 1 kg scientific payload consisting of an autofluorescing nephelometer, which is an instrument to detect suspended particles in the clouds. The goal is to search for organic chemicals in the clouds and explore their habitability. The probe will spend about 5 minutes and 30 seconds falling through the upper atmosphere, and then ideally continue transmitting data as it descends further toward the surface. "The mission is the first opportunity to probe the Venus cloud particles directly in nearly four decades," states a paper, published this week, describing the mission architecture. "Even with the mass and data rate constraints and the limited time in the Venus atmosphere, breakthrough science is possible."

Probably trolling, but I'll bite. People are starving because of corrupt and inept governments, not because of a fundament lack of money or food in the world. Look at the Sri Lankan governments disastrous policies as a prime example, borrowing billions to fund pointless white elephant projects, banning imported fertilizer on a whim and thus slashing the countries' agricultural output etc. You don't fix Sri Lankas problems with money or food; as long as they've got a government that acts like that, they will be poor, and there's no point suggesting that diverting money from things like scientific advancement, which will benefit everyone in the long run, would actually help.

I would not choose Sri Lanka as the examplar of inept government. A big problem in many superficially prosperous nations is how the surplus generated by hard working people is siphoned off and spirited away to secret offshore accounts. That is not well-meaning folly. It is corruption and theft, plain and simple.

Well, I mean it still has a CO2 atmosphere with sulphuric acid clouds even if the pressure and temperature and gravity level are comfortable for humans. So definitions of paradise may vary. As you point out, you need a sealed balloon habitat to actually live in. Still, you could, in theory have an outdoor pool and deck, wear just a bathing suit and a breathing mask with oxygen supply and sunbathe outdoors. Your sunscreen might also need have some sodium bicarbonate mixed in, in case some clouds roll through

What about the water? (Score:3)
As far as I know, life depends on liquid water. From what I have read of the climate on Venus, the surface temperature is hot enough to melt lead. Maybe things are cooler higher up in the thick Venusian atmosphere, so liquid water could exist in clouds of droplets.
One thing that is notable about life on earth, is that it can survive is very extreme conditions. One of my favourite nature stories about stuff living deep underground. There are bacteria that digest the rock, and produce gelatinous material, which experts call "snotites". One of the main byproducts of the snotite bacteria is sulphuric acid. This bacterial pee drips into a pool below. The acidic strength is equivalent to battery acid. There are blind transparent shrimps who just love swimming about in the acid. I missed the bit about what the shrimps live on. Fermented biologists, I expect, but I admit that is baseless speculation on my part.
The point is that this fantastic ecosystem still requires liquid water. Perhaps a worthy topic of study would be if there are cloudy communities of living things on our own planet, who live out their lives in ephemeral droplets. It would be a good deal cheaper to investigate that, than to send a robot probe to Venus.

Most of these cave systems have a water source which brings dissolved minerals and gasses into the cave. Chemosynthetic microbes consume those to grow, and a whole food-web is built on top of them. So, something grazes on the bacteria, something eats the grazers, etc. The sulphuric acid production is usually due to microbes oxidising hydrogen sulphide gas for energy, seeing as it's a bit difficult to photosynthesise in a dark cave.
