ENDURANCE (Environmentally Non-Disturbing Under-ice Robotic Antarctic Explorer) is an autonomous underwater vehicle designed to map in three dimensions the geochemistry and biology of underwater terrains in Antarctica. The vehicle was built and designed by Stone Aerospace, and is the second incarnation of the DEPTHX vehicle, which was significantly reconfigured for the challenges particular to the Antarctic environment.

Endurance (also related to , resilience, , , and hardiness) is the ability of an organism to exert itself and remain active for a long period of time, as well as its ability to resist, withstand, recover from, and have immunity to trauma, wounds, or fatigue. It is usually used in aerobic or anaerobic exercise. The definition of 'long' varies according to the type of exertion – minutes for high intensity anaerobic exercise, hours or days for low intensity aerobic exercise. Training for endurance can have a negative impact on the ability to exert strength unless an individual also undertakes resistance training to counteract this effect.
