    Exploration of Venus

    From the 60s to the 80s both Russia and USA sent multiple probes to explore Venus. It was the golden age of Venus exploration. We had other probes visit Venus since than but never in the scale of the earlier years.

    This is about to change. We have had a hint there might be life on Venus. This has started for request to send missions to Venus.

    It remains one of the most unexpected scientific discoveries of the year. To their astonishment, British scientists last week revealed they had uncovered strong evidence that phosphine – a toxic, rancid gas produced by microbes – exists in the burning, acid-drenched atmosphere of Venus.

    By rights, it should simply not be there. “All the geological and photochemical routes we can think of are far too underproductive to make the phosphine we have seen,” said Cardiff University astronomer Professor Jane Greaves, leader of the team who made the discovery. And that conclusion leaves scientists with the bizarre prospect that microbial activity – the key source of phosphine on Earth – may be occurring in the searing, acidic clouds that swathe Venus.

    Not surprisingly, the news that there may be bugs on Venus made front-page headlines. It also adds a bizarre new planetary focus for scientists hunting alien life on nearby planets – a search that is now leading them to increasingly strange and unexpected parts of the solar system, from the frozen moons of Jupiter to the methane-filled lakes of Titan, the largest moon of Saturn.

    "We've Found Possible Signs of Life in Venus's Clouds. Whoa."

    A mystery lurks in the clouds high above the stifling surface of our nearest planetary neighbor, Venus. Researchers have announced they've found traces of phosphine, a molecule potentially generated by living things, in the planet's clouds.

    Planetary scientists have long speculated that Venus's cloudy atmosphere could harbor life. The surface of Venus is inhospitable, with surface temperatures exceeding 800 degrees Fahrenheit. No probe sent to the planet—and there have been several—has survived for longer than a few hours. But the planet's atmosphere, which is composed of plush layers of sulfuric acid clouds, may present a unique cradle for burgeoning lifeforms.

    "We know that the molecule phosphine is a biomarker on Earth," astronomer Jane Greave, of Cardiff University in Wales, said in a pre-recorded statement released by the Royal Astronomical Society. "It's been suggested that there are possible habitats in the cloud decks of Venus, so somewhere where little lifeforms could live."

    I wonder if the airship-to-orbit concept by Powell would lend itself to Venus exploration with the envelope serving as habitat once there...
