The Artemis II astronauts have entered the Orion crew module, which they named "Integrity," with assistance from their closeout crew. This marks a key milestone in preparations for NASA's planned crewed lunar mission, the second in the agency's Artemis program aimed at returning humans to the Moon. The Orion spacecraft is the vehicle designed to transport astronauts to lunar orbit and back to Earth. The naming of the capsule reflects the crew's commitment to the mission's values and establishes a personal connection to the spacecraft they will depend on during flight. This step demonstrates the mission is advancing through critical pre-launch procedures and hardware integration.
