Artemis II Night Runs Dry Dress Rehearsals

NASA astronaut Christina Koch, Artemis II mission specialist, stands in the White Room on the crew access arm of the mobile launcher in the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida on Tuesday, Aug. 12, 2025. During a two-day operation, the Artemis II team practiced night-run demonstrations of different launch day scenarios like suit-up operations, walk-out, and arriving at the launch pad for the Artemis II test flight. Through the Artemis campaign, NASA will send astronauts to explore the Moon for scientific discovery, economic benefits, and to build the foundation for the first crewed missions to Mars – for the benefit of all.
