Koch and her crewmates talked with some of their International Space Station (ISS) counterparts on Tuesday (April 7), a day after Artemis 2's epic flyby of the moon. And the station astronauts had lots of questions for the deep-space explorers.
"We know how fortunate all of us are as humans to come up here and look down at the Earth from above; every astronaut that comes to space remarks on that," Meir said.
She was referring to the "overview effect," the often life-changing shift in perspective that comes from seeing our planet as it truly is — a fragile world that looks very alone in a vast and dark cosmos.
"We really wanted to hear what that felt like, and how different that felt now from your new perspective around the moon," Meir continued.
"I'll start by saying we do miss the ISS," Koch responded. (Wiseman and Glover have also lived aboard the station; Hansen is a spaceflight rookie.) "The views there are awesome, being able to see specific places — being able to see your home, specifically. So y'all's views are absolutely incredible, and I miss them every day, almost."

"The thing that changed for me looking back at Earth was that I found myself noticing not only the beauty of the Earth, but how much blackness there was around it, and how it just made it even more special," Koch said.
"It truly emphasized how alike we are, how the same thing keeps every single person on planet Earth alive," she added. "We evolved on the same planet, we have some shared things about how we love and live that are just universal, and the specialness and preciousness of that really is emphasized when you notice how much else there is around it."
All four Artemis 2 crewmates — Koch, fellow NASA astronauts Reid Wiseman and Victor Glover, and Jeremy Hansen of the Canadian Space Agency — took part in the 15-minute call.
On the ISS, Meir shared the microphone with NASA's Chris Williams and Jack Hathaway, and Sophie Adenot of the European Space Agency. The three cosmonauts currently living on the orbiting lab — Sergey Kud-Sverchkov, Sergei Mikaev and Andrey Fedyaev — did not participate.
Adenot asked the Artemis 2 astronauts what has surprised them during their mission so far.
"I don't mean to give you such a short answer, but I can truly say 'everything,'" Glover replied.
He cited many of the mission's major milestones, from its April 1 liftoff atop a Space Launch System rocket to its maneuvers in Earth orbit to its journey to, and flyby of, the moon.
"This entire journey has been interesting," Glover said.
Artemis 2 — the first crewed mission beyond Earth orbit since Apollo 17 in 1972 — is now headed back to Earth. The four astronauts will get here on Friday (April 10), splashing down that evening off the coast of San Diego.
NASA will then start gearing up for Artemis 3, which will test docking and rendezvous technologies in Earth orbit in 2027. After that will come Artemis 4, which aims to land astronauts near the moon's south pole in late 2028.
