NASA Administrator Jared Isaacman announced on Monday that Artemis II has reached its farthest point from Earth, traveling over 250,000 miles away.

The spacecraft’s crew — Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen — were 252,756 miles from Earth shortly after 7 p.m.

“On the far side of the Moon, 252,756 miles away, Reid, Victor, Christina, and Jeremy have now traveled farther from Earth than any humans in history and now begin their journey home,” Isaacman said on X. “Before they left, they said they hoped this mission would be forgotten, but it will be remembered as the moment people started to believe that America can once again do the near-impossible and change the world.”

“Congratulations to this incredible crew and the entire NASA team, our international and commercial partners, but this mission isn’t over until they’re under safe parachutes, splashing down into the Pacific,” he added.

Meanwhile, during their lunar survey, the Artemis II astronauts said they observed unusual colors on the Moon’s surface.

While much of the landscape was brown, some areas showed distinct greenish tones, they said.

” Something I just heard from the window team is the more I look at the moon and the browner and browner it looks, I thought that was an interesting observation,” Mission Specialist Christina Koch said during a NASA transmission.

Canadian astronaut Jeremy Hansen reported seeing the greenish hues near the Aristarchus Plateau, a large and relatively young crater.

The crew noted that this coloration was unique and hadn’t been observed elsewhere on that side of the Moon.
