The three Americans and one Canadian slated to fly on NASA’s Artemis II circumlunar mission had a “pinch me” moment Monday when they got their first chance visit the Orion spacecraft that will carry them around the Moon and back to Earth.

The astronauts had an opportunity to peer through the hatch of the Orion crew capsule for the Artemis II mission, now largely complete and going through some final tests before it is connected to its power and propulsion module at NASA’s Kennedy Space Center in Florida.

“We all said when we walked up to it the first time, that it gave us chills, and it really does,” said Christina Koch, a mission specialist on the Artemis II mission. “So it’s a new way that I feel bonded with this crew and also with the team.”
