A Quote by David Grinspoon
It's one of the big mysteries about Venus: How did it get so different from Earth when it seems likely to have started so similarly? The question becomes richer when you consider astrobiology, the possibility that Venus and Earth were very similar during the time of the origin of life on Earth.

I did not want to write a story about the invasion of Earth, so I had to create a race capable of living nearby, which meant to either on the Moon, on Mars, or on Venus. I picked Venus.
My best friend Rosemarie and I had a very involved secret life when we were in elementary school. After we saw 'The Day the Earth Stood Still' on TV, we invented a whole secret life in which we were twins from the planet Venus, and we were in charge of the entire solar system as well as Earth.
I intend to apply the perspective of astrobiology, which is a deep-time way of looking at life on Earth, towards the question of the Anthropocene. What does the human phenomenon on Earth look like viewed from an interplanetary perspective?
There is good evidence that Venus once had liquid water and a much thinner atmosphere, similar to Earth billions of years ago. But today the surface of Venus is dry as a bone, hot enough to melt lead, there are clouds of sulfuric acid that reach a hundred miles high and the air is so thick it's like being 900 meters deep in the ocean.
The Earth is the Lord. Everybody walks on the earth. And nobody respects the Earth. Everybody who walks on the earth, shits on the Earth. Spits on the Earth. Don't respect the Earth. So the Earth didn't like it. So the Earth call for a revolution. And the earth is fighting back. The Earth call for a revolution. The Earth call for justice. And the Earth get justice. 'Cause the Earth release ganja. The Earth release herbs.
It will be a long time, if ever, before we get to study Earth-like planets orbiting around other stars, so really, the study of Venus and Mars is the best opportunity that we have, and can imagine having anytime in the future, to understand the evolution of Earth-like planets.
Earth walks on Earth, Glittering in gold; Earth goes to Earth, Sooner than it wold; Earth builds on Earth, Palaces and towers; Earth says to Earth, Soon, all shall be ours.
Venus and Mars are our next of kin: they are the two most Earth-like planets that we know about. They're the only two other very Earth-like planets in our solar system, meaning they orbit close to the sun; they have rocky surfaces and thin atmospheres.
There was a long history of people believing there was life on Venus. It was about the same size as Earth. It had clouds. It was commonly believed it was tropical - wet, hot and steamy.
My relationship to the desecration of the earth was very theoretical and intellectual until I got sick. I could never watch anything about polar bears dying or the death of bees. There were certain things I knew I couldn't go near because they were too devastating. But I don't think until I got cancer did I get it in my body, what was happening to the earth. I finally went: "Oh! Earth! Organism!"
Earth is going to lose its oceans in the future, just as Venus did in the past. How long planets retain their oceans is a function of distance from the sun, all other things being equal.
There are other planets besides the Earth and Mars. I'd like to remind you that studying Venus is vital to understanding life elsewhere.
It is only of life on Earth, however, that one can speak with any certainty. It seems to me that all life on Earth, the sum total of life upon the Earth, has purpose.
It has been discovered that all the world is made of the same atoms, that the stars are of the same stuff as ourselves. It then becomes a question of where our stuff came from. Not just where did life come from, or where did the earth come from, but where did the stuff of life and of the earth come from?
It's quite possible there's as much lightning on Venus as on Earth.
There's a lot to do in space. I want to learn more about the greenhouse effect on Venus, about whether there was life on Mars, about the environment in which Earth and the Sun is immersed, the behavior of the Sun.
