For Glover, the “greatest gift” of the mission was seeing the lunar eclipse from beyond the far side of the moon.

For Wiseman, the “pinnacle moment” was when his team named a lunar crater after Wiseman’s late wife, Carroll, who died of cancer in 2020.

“I think when Jeremy spelled Carroll’s name …. I think for me that is when I was overwhelmed with emotion and I looked over and Christina was crying,” Reid said.

“Just for me personally, that was kind of the pinnacle moment of the mission for me,” he continued.

The crew also said they were getting their source of news from planet Earth from their family members.

They have “been our source of how the mission is going from the public perspective,” Wiseman said, before adding “obviously they’re all biased”.

When asked by BBC’s News Science Editor Rebecca Morelle what the crew will miss most about being space, Christina Koch said she will miss the “camaraderie”.

On what she won’t miss, Koch said there wasn’t anything.

“We can’t explore deeper unless we are doing a few things that are inconvenient, unless we’re making a few sacrifices, unless we’re taking a few risks. And those things are all worth it,” she said.

The crew now face several quieter days of checks and experiments before a final ordeal: a fiery plunge through the atmosphere at nearly 25,000mph and a parachute splashdown into the Pacific that will test the capsule’s heatshield and recovery systems.
