Four astronauts traveling back to Earth from the far side of the moon on ​NASA’s Artemis II mission spoke of their emotions as they wrapped up the unprecedented flight and prepared to re-enter the atmosphere in a “fireball”, during their first press conference from space on Wednesday. The Artemis II crew, flying in their Orion capsule since launching from Florida last week, are due to splash down off the Southern California coast on Friday evening after reaching the moon earlier this week. They cruised along ​a path that took ‌them past the shadowed, lunar far side to become the farthest-flying humans in history.
