Set against the iconic, retro-futuristic backdrop of the University of Arizona’s Biosphere 2 in Oracle, Arizona, the 2026 STAR Summit brought an intensive, five-day astronaut readiness experience to life. This unique training expedition pushed aerospace professionals, analog mission candidates, and high-performance operators out of their comfort zones through demanding, real-world team challenges. Utilizing the sprawling, closed-ecological systems of the Biosphere 2 campus and a full-day guided underground cave expedition, our photography documents the raw, unscripted moments of human performance under pressure—capturing the exact skills, communication, and cohesion required to lead the future of space exploration.
