Perhaps because I wasn’t alive during Apollo, part of me has often gravitated to robotic space missions. I identified with spacecraft like Voyager, Cassini, New Horizons, and the rovers traversing Mars as examples of real exploration. It was still possible to connect crewed platforms in low-Earth orbit, like the International Space Station, with the idea of exploring through the attainment of knowledge. With more than 25 years of uninterrupted crewed operations, the ISS has taught NASA and its international partners how to live and work in space and paved the way for the establishment of a permanent base on the Moon.

But it was easy to connect the innate drive to explore with the excitement of seeing new landscapes on Mars, the ghostly plumes of Enceladus, and the heart of Pluto. These were new worlds revealed for the first time, and each discovery sparked a bevy of new questions.

Artemis II struck the same vein, revealing things unseen by human eyes before. Like those missions far out in the Solar System, this was exploration in action. But seeing and hearing what the Artemis II astronauts saw added another dimension. It scratched an itch that a robot can’t reach. Here were human beings, people I’ve met and people you might someday meet, going through an entirely new experience. //

Sure, Artemis II didn’t land on the Moon. That will come on a future Artemis flight. But these four astronauts ventured to greater distances than Apollo and saw parts of the far side of the Moon hidden from view during those missions more than 50 years ago. Modern technology provided new opportunities for the astronauts to share their views with the world—from their view, just a fragile blue marble suspended in a cosmic void.

Speaking from the Orion spacecraft on April 4, Glover, the mission’s pilot, remarked on the view in a long-distance virtual interview with CBS News.

“One of the really important personal perspectives that I have up here is I can really see Earth as one thing,” Glover said on the eve of Easter. “You guys are talking to us because we’re in a spaceship really far from Earth, but you’re on a spaceship called Earth that was created to give us a place to live in the Universe, in the cosmos.

“Maybe the distance we are from you makes you think what we’re doing is special, but we’re the same distance from you, and I’m trying to tell you—just trust me—you are special. In all of this emptiness—this is a whole bunch of nothing, this thing we call the Universe—you have this oasis, this beautiful place that we get to exist together.

“As we go into Easter Sunday, thinking about all the cultures all around the world, whether you celebrate it or not, whether you believe in God or not, this is an opportunity for us to remember where we are, who we are, and that we are the same thing, and that we’ve got to get through this together.” //

“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 was just this lifeboat hanging undisturbingly in the Universe,” she said. “I know I haven’t learned everything that this journey has yet to teach me, but there is one new thing I know, and that is planet Earth, you are a crew.”
