What is an Analog Site?
An analog site is a location on Earth that shares one or more characteristics with an environment on another planetary body.
Discover extraordinary places on Earth that help scientists understand the Moon and Mars, and prepare for future space exploration.
Before humans explore distant worlds, scientists study environments on Earth that share specific characteristics with planetary surfaces. These environments are called Planetary Analog Sites.
Discover Earth's environments that resemble other planetary worlds.
Discover our selected Moon and Mars analog environments around the world.
Discover research projects and missions connected to terrestrial analog environments.
An analog site is a location on Earth that shares one or more characteristics with an environment on another planetary body.
Earth provides accessible environments for testing instruments, studying geological processes and preparing exploration missions.
Analog research helps scientists understand environmental challenges before sending robotic systems and astronauts into space.
No place on Earth perfectly reproduces Mars or the Moon. Gravity, atmospheric pressure, radiation and other conditions remain fundamentally different. Analog research focuses on specific similarities, not complete equivalence.
