On Monday, the four astronauts of Artemis II observed the far side of the moon, setting distance records and experiencing a solar eclipse

NASA has launched four astronauts on a pioneering journey around the moon—the Artemis II mission. Follow our coverage here.

The Artemis II Orion spacecraft hit the peak of its trip around the moon on Monday—the first time humans have passed near our natural satellite in more than 50 years. As they made the flyby, the four astronauts onboard traveled farther in space than any human before them.

The crew exceeded the distance record set by the 1970 Apollo 13 mission just before 2 P.M. EDT. Shortly after that, starting around 2:45 P.M., they had at least five critical hours to observe the far side of the moon as parts of it were illuminated by the sun. Throughout the study period, astronauts Reid Wiseman, Victor Glover, Christina Koch and Jeremy Hansen took turns making observations at Orion’s windows, as well as offering one another technological support and taking quick breaks to eat.

After passing the Apollo distance record, Hansen offered suggested appellations for two previously unnamed lunar features: a crater to be called Integrity after the name the crew gave to the Orion spacecraft and a bright spot on the near-far-side boundary to be named Carroll in memory of Wiseman’s late wife, Carroll Taylor Wiseman, Hansen said.

As the crew rounded the moon, they made several key observations, including of the moon’s color, texture and “albedo” (brightness and darkness), as well as structures such as the massive Orientale Basin. This nearly 600-mile-wide impact crater has never been directly seen by human eyes before this mission. Over the course of the flyby, the Orion spacecraft will came within about 4,070 miles of the lunar surface.

“It’s very apparent, all the really bright new craters,” Koch said in her observations, noting they were something she had “never seen” in photographs. “Some of them are super tiny. Most of them are pretty small. There’s a couple that really stand out, obviously. And what it really looks like is like a lampshade with tiny [prick] holes and the light shining through. They are so bright, compared to the rest of the moon.”

On Earth, NASA’s lunar science team was on deck to monitor the crew’s observations.

“I know that the live broadcast tomorrow will flash to them occasionally throughout the broadcast. You’re going to see some very excited scientists. They’re going to be absolutely buzzing up there,” said Kelsey Young, lunar science lead for the Artemis II mission at NASA’s Science Mission Directorate, at a press conference on Sunday night.

At around 6:44 P.M., the crew lost communication with Earth. This period lasted for about 40 minutes—they reemerged around 7:25 P.M. "I said that we do not leave Earth, but we choose it," Koch said as the crew came back into range, recalling her declaration uttered four days prior when the Orion spacecraft had embarked toward the moon. "And that is true, 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," she concluded. "We will always choose each other."

About an hour later, the crew also witnessed a solar eclipse, as the moon blocked out the sun. Lunar observations ended at about 9:35 P.M., marking the point at which the astronauts will transition to focus on the journey back to Earth; they’re set to splash down on April 10.
