Watch live: NASA’s Artemis II’s moon flyby is underway
Today the four astronauts of Artemis II are observing the far side of the moon, setting distance records and experiencing a solar eclipse
The moon’s near side is seen, as is the Orientale Basin, a massive impact crater that is generally not visible from Earth. The Orientale Basin is the large crater west of the lava flows.
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 is officially starting the peak of its trip around the moon—the first time humans have passed near our natural satellite in more than 50 years. As they make the flyby, the four astronauts onboard will travel 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 have at least five critical hours to observe the far side of the moon as parts of it are illuminated by the sun. Throughout the study period, astronauts Reid Wiseman, Victor Glover, Christina Koch and Jeremy Hansen will take turns making observations at Orion’s windows, as well as offering one another technological support and taking quick breaks to eat.
Shortly 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 and “at the same latitude as Ohm [crater]” to be named Carroll in memory of Wiseman’s late wife, Carroll Taylor Wiseman, Hansen said.

NASA’s Artemis II live mission coverage.
As the crew rounds the moon, there are several key observations they will make, 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 come 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.”
Just northwest of the Orientale Basin (marked above) is a crater that the Artemis II crew would like to name Integrity, after their spacecraft and this historic mission. Just northeast of the proposed Integrity crater, on the moon’s near and far side boundary, which is sometimes visible from Earth, is an unnamed crater that the crew suggested be designated Carroll in honor of crew member Reid Wiseman’s late wife, Carroll Taylor Wiseman, who passed away on May 17, 2020.
On Earth, NASA’s lunar science team will be 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.
And at 6:44 P.M. NASA predicts the crew will lose communication with Earth for about 40 minutes—they will reemerge around 7:25 P.M. About an hour later, the crew will then see a solar eclipse, when the moon will block out the sun. Lunar observations will end at about 9:20 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.
