NASA astronaut Christina Koch and Canadian Space Agency astronaut Jeremy Hansen took off on a T-38 training flight from Ellington Field on February 11, 2026, with a waning crescent Moon hanging above them. The image is almost too on-the-nose: two members of the crew that will fly humanity's first lunar flyby mission in over half a century, climbing toward the very object they're training to reach. The T-38 Talon is NASA's astronaut proficiency aircraft — a two-seat supersonic jet trainer that has been in the agency's fleet since the 1960s. It's not a spacecraft simulator. It's a decision-forcing machine. Pilots use it to maintain sharp cockpit resource management, practice communication under workload, and keep their reflexes calibrated for high-performance flight. Every Artemis crew member flies regular T-38 sorties as part of mission readiness. Koch and Hansen are two of the four Artemis II crew members who will ride an Orion spacecraft around the Moon on a roughly 10-day mission — the first crewed flight of NASA's Space Launch System and the first time humans have traveled beyond low Earth orbit since Apollo 17 in December 1972. Koch, a NASA astronaut who previously spent 328 consecutive days aboard the International Space Station, and Hansen, a Canadian Space Agency astronaut and former CF-18 fighter pilot, represent the international character of the Artemis program. The photograph itself is a quiet document. No launch pad, no spacecraft, no mission control. Just two astronauts in a 60-year-old jet design, lifting off from a Houston airfield with the Moon in frame. It's the unglamorous middle of a years-long preparation cycle — the part that doesn't make the highlight reel but makes the mission possible. Ellington Field, adjacent to NASA's Johnson Space Center, has been the home of astronaut flight operations since the Gemini program. The continuity is notable: the same airfield, the same type of training aircraft, the same purpose — keeping human reflexes and judgment sharp enough to trust with a spacecraft. The Moon above is the only thing that's changed.
