Mars habitability analogue environments on Earth

Habitability Analogue Environments on Earth are places on our planet that have similar conditions to those found on the planet Mars. Scientists use these places to study how living things could survive on the planet Mars. For example, they might look at how plants, insects, and animals live in cold, dry, and salty places like deserts and dry lakes on Earth to understand how they might survive on Mars.
