NASA Tests Coupling Device for Orbital Propellant Depots

NASA validated a cryocoupler—a spacecraft-to-depot coupling interface—on 26 June 2026, advancing infrastructure for in-space refueling. The device manages extreme temperatures and microgravity fluid dynamics required to transfer cryogenic propellants between vehicles. Cryogenic Fluid Management (CFM) remains a foundational challenge for any depot architecture; this hardware milestone bridges the gap between ground testing and on-orbit qualification.
