The Overview Effect is when a transformational change occurs in astronauts when they view the Earth from space and realize just how small and alone and isolated Earth really is.

The Earth's atmosphere...which looks so big and deep when we look from the ground upwards...is actually a very thin line when seen from space...

That Thin Blue Line is...Our Atmosphere!

Astronaut Christina Koch explained about viewing Earth from the ISS:

  • “The overview effect is when you’re looking through the cupola and you see the Earth as it exists with the whole universe in the background. You see the thin blue line of the atmosphere, and then when you’re on the dark side of the Earth, you actually see this very thin green line that shows you where the atmosphere is. What you realize is every single person that you know is sustained and inside of that green line and everything else outside of it is completely inhospitable. You don’t see borders, you don’t see religious lines, you don’t see political boundaries. All you see is Earth and you see that we are way more alike than we are different.”
An Orange Analogy with Earth...

Imagine an orange but into two...

The outer skin can be likened to be our Earth's atmosphere...a very thin layer between us and the infinite depths and coldness of space...

The rind can be likened to the crust of the Earth...and our land that we stand upon and traverse is but a very thin layer between the skin and rind that we can imagine but not really see in the orange...

And one little orange amongst the whole world...is insignificant and fragile...

And some very, very informative quotations:

Yuri Gagarin (Vostok 1; 1961) wrote, "Circling the Earth in a spaceship, I marveled at the beauty of our planet. People, let us preserve and increase this beauty, not destroy it!"

Michael Collins (Apollo 11; 1969) said that "the thing that really surprised me was that it [Earth] projected an air of fragility. And why, I don't know. I don't know to this day. I had a feeling it's tiny, it's shiny, it's beautiful, it's home, and it's fragile".

Edgar Mitchell (Apollo 14; 1971) described it as an "explosion of awareness" and an "overwhelming sense of oneness and connectedness... accompanied by an ecstasy... an epiphany".

Ed Gibson (Skylab 4; 1976) said "In no way could we on earth, or any group of people, or any country, consider ourselves isolated. [...] We're really all in this together".

William Shatner (Blue Origin NS-18, 2021) said immediately after landing that, "Everybody in the world needs to do this. [...] The covering of blue was... the sheet, this blanket, this comforter of blue that we have around us, we think, "Oh, that's blue sky." And then [...] you shoot through it all of a sudden, as though you whip off a sheet off you when you're asleep, and you're looking into blackness, into black ugliness, and you look down. There's the blue down there, and the black up there and it's... There is mother, and Earth, and comfort. And there is — is there death? I don't know. [...] It was so moving to me. This experience, it's something unbelievable."

Ed Dwight (Blue Origin NS-25, 2024) reflected after his suborbital spaceflight, "Out the window, I could see the Earth. Everything looked ordered and neat and wonderful and beautiful. There was no separation between countries or states. And you ask yourself: As wonderful as it all is, why can't the people who live on it get along? Why don't they want to take care of such a beautiful place?"

When Cai Xuzhe (Shenzhou 19, 2024–2025) returned to Earth after six months of living on China's space station he said, "In space, we gazed at the beautiful blue planet countless times. This is the common home for humanity and needs to be protected by all of us together."

These few words say much...

Why can't we take care of our planet? And each other? And our Future?

Yes, environmental concerns and activities are quite necessary and I support both.

But why do we trash our planet for profit, for convenience, for irresponsibility?

Lack of Sentience.

And Sentient Consciousness.

Here in this website I will explore and Teach this...

And maybe we can take care of our beautiful planet and our Human People also.
