“It’s blowing my mind”: When Artemis II returns to Earth—and what astronauts saw on the lunar flyby

After traveling deeper into space than any other humans, the Artemis II astronauts pointed their moonship toward home Monday night, wrapping up a lunar cruise that revealed views of the far side never beheld by eyes until now.

Their flyby of the moon — NASA’s first return since the Apollo era — even included some celestial sightseeing besides yielding rich science. It was a significant step toward landing boot prints near the moon’s south pole in just two years.

A total solar eclipse greeted the three Americans and one Canadian as the moon temporarily blocked the sun from their perspective. Mercury, Venus, Mars and Saturn nodded at them from the black void. The landing sites of Apollo 12 and 14 also were visible, poignant reminders of NASA’s first age of exploration more than half a century ago.

In an especially riveting retro throwback, Artemis II shattered the distance record set by Apollo 13 in 1970. NASA’s Orion capsule reached a maximum distance of 252,756 miles (406,771 kilometers) from Earth before hanging a U-turn behind the moon, 4,101 miles (6,600 kilometers) farther than Apollo 13.

“It is blowing my mind what you can see with the naked eye from the moon right now. It is just unbelievable,” Canadian astronaut Jeremy Hansen radioed. He challenged “this generation and the next to make sure this record is not long-lived.”

As the flight continues, here’s what to know and when the Artemis II will return to Earth.

Artemis II route: When will it return to Earth?

Artemis II’s lunar fly-around and intense observation period lasted seven hours, by far the highlight of the nearly 10-day test flight. It will end with a splashdown Friday, April 10, in the Pacific Ocean off the coast of California.

Artemis II is using the same maneuver that Apollo 13 did after its “Houston, we’ve had a problem” oxygen tank explosion wiped out any hope of a moon landing.

Known as a free-return lunar trajectory, this no-stopping-to-land route takes advantage of Earth and the moon’s gravity, reducing the need for fuel. It’s a celestial figure-eight that put the astronauts on course for home once they emerged from behind the moon Monday evening.

What are the astronauts doing?

The astronauts are on a lunar fly around. No circling around the moon, no stopping for a moonwalk — just a quick out-and-back lasting less than 10 days. They’ve been poring over maps and satellite images of the lunar far side and anticipate a photo frenzy.

Monday, the Artemis II crew captured never-before-seen regions of the lunar far side — with the moon appearing the size of a basketball at arm’s length during the closest part of the roughly seven-hour flyby.

The first breathtaking images captured onboard Orion were photos showing the moon getting noticeably bigger.

“This is a very taxing event on the eyes, looking out the window and seeing a very bright moon,” said NASA astronaut Victor Glover, the Artemis II pilot.

“All the really bright new craters, many of them are really tiny. Most of them are pretty small,” astronaut Christina Koch said.

Venturing as close as 4,067 miles (6,545 kilometers) to the gray dusty surface, the astronauts zipped through a list of more than two dozen targets, using powerful Nikon cameras as well as their iPhones to zoom in on impact craters and other intriguing lunar features.

Before getting started, they requested permission to name two bright, freshly carved craters. They suggested Integrity, the name of their capsule, and Carroll, commander Reid Wiseman’s wife, who died of cancer in 2020.

Wiseman wept as Hansen put in the request to Mission Control, and all four astronauts embraced in tears.

“Such a majestic view out here,” Wiseman radioed once he regained his composure and started picture-taking. The astronauts called down that they managed to capture the moon and Earth in the same shot, and they provided a running commentary to scientists back in Houston on what they were seeing.

At one point, Koch reported an overwhelming sensation of emotion for a second or two while zooming in on the moon. “Something just drew me in suddenly to the lunar landscape and it became real,” she said.

The Artemis II astronauts made their closest approach to the moon and reached their maximum distance from Earth, while they were out of contact for about 40 minutes. Their speed at closest approach: 3,139 mph (5,052 kph). The spacecraft accelerated as it appeared from behind the moon and the planned communications blackout and made tracks for Earth.

An Earthrise came into view showing Asia, Africa and Oceania as Mission Control called out: “We are Earthbound and ready to bring you home.” Flight controllers in Houston flipped their mission patches over to signify the return leg.

President Donald Trump phoned the astronauts following the flyby, calling them “modern-day pioneers.”

“Today you’ve made history and made all America really proud, incredibly proud,” the president said, adding that more lunar traveling is coming and ultimately “the whole big trip to Mars.”

Wiseman and his crew spent years studying lunar geography to prepare for the big event, adding solar eclipses to their repertoire during the past few weeks. By launching last Wednesday, they ensured themselves of a total solar eclipse from their vantage point behind the moon, courtesy of the cosmos.

Topping their science target list: Orientale Basin, a sprawling impact basin with three concentric rings, the outermost of which stretches nearly 600 miles (950 kilometers) across.

Their moon mentor, NASA geologist Kelsey Young, expects thousands of pictures.

What comes after Artemis II?

Artemis II is NASA’s first astronaut moonshot since Apollo 17 in 1972. It sets the stage for next year’s Artemis III, which will see another Orion crew practice docking with lunar landers in orbit around Earth. The culminating moon landing by two astronauts near the moon’s south pole will follow on Artemis IV in 2028.
