OTTAWA, ONTARIO — On their record-setting journey around the moon and back, the Artemis II astronauts experienced awe that remains hard to put into words, the team said at a recent public appearance in Canada.

One of the crew’s most memorable mission moments was watching the sun disappear behind the moon for 53 minutes on April 6, marking a unique solar eclipse visible only from space. NASA’s Reid Wiseman, however, wasn't initially focused on the celestial sight. He had his responsibilities on his mind.
