During re-entry, Cdr Wiseman told Mission Control the crew had a “great view of the Moon”, although he admitted: “It looks a little smaller than yesterday.”

Jacki Mahaffey, on the communications desk at Mission Control Houston, responded: “I guess we’ll have to go back.”

Following 10 days in space, Commander Reid Wiseman started by telling the crowd in Houston, Texas on Saturday: “I have no idea what to say.” He said no one on Earth will know what he and his fellow astronauts went through and they were “bonded” forever. Wiseman said:  “Before you launch, it feels like it’s the greatest dream on Earth.

“This was no easy… when you’re out there, you just want to get back to your families and friends.

“It’s a special thing to be human and a special thing to be on planet Earth.”

Ms Koch said she was struck by her view of Earth from space.

“Honestly, what struck me wasn’t just Earth, it was all of the blackness around it. Earth was just this lifeboat hanging undisturbably in the universe. Planet Earth you are a crew,” she said.

Canadian Space Agency President Lisa Campbell called the mission “a powerful moment.”
