The Artemis II crew honored NASA commander Reid Wiseman’s late wife, Carroll Wiseman, in an emotional tribute on Monday.

Wiseman, one of four astronauts on the Artemis II mission, lost Carroll, a 46-year-old pediatric nurse practitioner, to cancer in 2020. Carroll was survived by Reid and their two daughters, Ellie and Katherine, according to an obituary in The Virginian-Pilot.

In remarks to mission control, the crew announced that they would like to name an unnamed crater on the moon for Carroll.

“There’s a feature in a really neat place on the moon, and it is on the near side, far side, boundary. In fact, it’s just on the near side of that boundary, and so at certain times of the moon’s transit around Earth, we will be able to see this from Earth,” CSA astronaut Jeremy Hansen said, his voice breaking at times. “We lost a loved one, her name was Carroll, the spouse of Reid, the mother of Katie and Ellie. And if you want to find this one, you look at Glushko, and it’s just to the northwest of that at the same latitude as Ohm. And it’s a bright spot on the moon. And we would like to call it ‘Carroll.’”

Reid Wiseman could be seen on video wiping away tears as he put his hand on Hansen’s shoulder. The four crew members, which also includes astronauts Victor Glover and Christina Koch, then embraced in a hug.
