8 Amazing Places You Can Visit ‘Mars’ on Earth

Astronauts from five space agencies explore caves in Sardinia as part of a training course designed to teach them how to work effectively in multicultural teams when safety is critical.

A handful of faux space missions exist around the world, and scientists are using them to study various aspects of how humans respond to the challenges of traveling and living in deep space environments. In the space investigation world, these places are called “analogs.” An Analog is a situation on Earth that produces effects on the body similar to those experienced in space, both physical and mental/emotional. These studies help prepare us for long duration missions.

This National Geographic article highlights eight such places around the world with rich descriptions of the analog environment and what the research seeks to accomplish to get us one step closer to Mars.
