People debated over whether Venus ever had a moon. If Venus had a satellite at one point, could that satellite eventually impacted onto the surface and caused some catastrophe³ to happen? We don't know. It could've been possibly a factor.

 

Perhaps such an impact explains both the strange calendar and climate on Venus. Was it hit hard enough to flip⁴ upside down? And for its day to be slowed to a crawl? Was this the moment Venus'climate was thrown into chaos⁵?

 

Whatever the cause of Venus' climate calamity⁶, could Iife have ever survived such an ordeal⁷?

 

If I had to guess or I had to bet, I would say,Yeah, the Venus did have life.

And I say that because what we do understand about life on Earth is that it started early and doesn't seem to have required any extraordinary conditions.

 

If there was life of our kind, the organic kind, on the surface of Venus a long time ago, then what happened to that life?

 

Well one possibility is that it just died out. But there's another possibility

that's a little more exotic, which is it may have migrated up into the clouds.

 

There is some speculation⁸ that Venus might actually still harbor life even

though it is such a hostile place.

 

And the reasoning is that at one time Venus was like the Earth in the first two billion years or so of its history. So if life were to grab a hold, maybe life was able to stay ahead of the environmental disaster that befell Venus as

the water basically left the planet.

 

Could life really exist in the clouds of Venus?  The best way to know for sure is to float into the atmosphere and find out. Right behind us is the Valor⁹ balloon which we intend to fly in the skies of Venus in a couple of years from now.
