Research

An Analog, is a research method and field test environment.

It focuses on investigating one or several aspects of crewed space missions using simulations as an analogue to an off-world scenario. Analog tests and studies can include new technologies or procedures tests, life support systems, robotic equipment, architecture, communications, health and well-being, team dynamics, performance, menu fatigue, and other human factors.

Although the Analogs cannot provide all aspects of human spaceflight, the advantages of accessibility and affordability allow for a larger sample size (statistical research) than from the studies done on real astronauts in space. The possibility to control of external events that could influence performance and the state of the crew allows for unique psychological studies and procedure tests. Simulated space mission conditions and limitations (such as isolation, confinement (ICE), and self-sufficiency) can be dangerous factors themselves.
