We've had another global inoculation of the Overview Effect.

We're the first species to look back on our planet from beyond it.

The power of seeing Earth in the vast darkness of space changes history.

Healing our planet might seem like a moonshot, but the Artemis II crew reminded us we can do it with joy.

"Trust us, you look amazing, you look beautiful. And from up here, you also look like one thing. Homo sapiens, all of us, no matter where you're from or what you look like, we're all one people." ~ astronaut Victor Glover

Across the billions of years that life has existed on Earth, we are the very first species to look back on our planet from beyond it. And that experience, humanity seeing Earth hanging in the great, vast blackness of space, has changed our own humanity, our own history.

Earthrise has long been considered the world's most famous photograph: It helped inspire the world's environmental movement along with the enormous outpouring of people on the first Earth Day in 1970—20 million Americans participated and demonstrated. By the end of that year, the Environmental Protection Agency had been created, along with the Clean Air Act, Clean Water Act, National Environmental Education Act, and more.

With the Artemis II mission, and their bubbling, contagious Moon Joy, we've had another global inoculation. It's a phenomenon that scientists and psychologists are just beginning to explore: the overview effect.

Even writers, artists, actors, scientists, and politicians are just scratching the surface of how to relay the incandescent changes to human beings who peer back at Earth from space. The astronauts themselves begin to capture it.

I don't know what we all expected to see... it was the most spectacular moment, and it paused all four of us in our tracks. There is nothing normal about this. Sending four humans 250,000 miles away is a Herculean effort, and we are now just realizing the gravity of that.

And as they watched Earth set from their vantage behind the moon, Wiseman said,

No matter how long we look at this, our brains are not processing this image in front of us. It is absolutely spectacular, surreal. I know there’s no adjectives. I’m going to need to invent some new ones to describe what we are looking at out this window.

Our Earthside awe refresher couldn't come at a better time. Earth, and every living thing that lives here, faces unprecedented crises. Yet, good news is on the horizon, and there are scientists working to help bring Earth back into the only safe zone people have ever known.

Astronaut Christina Koch had this to say about our existential togetherness:

"A crew has the same cares and the same needs, and a crew is inescapably, beautifully, dutifully linked ... When we saw tiny Earth, people asked our crew what impressions we had. And honestly, what struck me wasn’t necessarily just Earth, it was all the blackness around it... (Earth is a) lifeboat hanging undisturbingly in the universe." "I know I haven’t learned everything that this journey has yet to teach me, but there’s one new thing I know, and that is, planet Earth, you are a crew."

"I know I haven’t learned everything that this journey has yet to teach me, but there’s one new thing I know, and that is, planet Earth, you are a crew."

And when Koch came home, she said,

"We will explore. We will build. We will build ships. We will visit again. We will construct science outposts. We will drive rovers. We will do radio astronomy. We will found companies. We will bolster industry. We will inspire. But ultimately, we will always choose Earth. We will always choose each other."

This Earth Day, choosing our planet, choosing each other, might seem like a moonshot, but Artemis II and her crew have taught us we can do it with joy.

And if you want a little more inspiration? The Artemis II crew's awed revelations join Carl Sagan's now famous clip from his breatkthrough series, Cosmos. Here he describes our Pale Blue Dot in an image taken from four billion miles away in some of the most beautiful words ever spoken on the overview effect.
