NASA astronaut Christina Koch, Artemis II mission specialist, smiles as she closes the door to the mine-resistant ambush protected vehicle, or MRAP, at Launch Complex 39B where the Artemis II flight crew practiced emergency egress scenarios 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.
