A new paper proposes that Deception Island in Antarctica is one of the best places on Earth to simulate the Martian environment.
The paper identifies 30 sites on the island that correspond well to places on Mars.
Deception Island in Antarctica serves as a valuable Mars analogue site due to the combination of extreme environmental conditions and geological features that mirror those found on Mars.
The island's unique features include perchlorate, glaciovolcanic processes, permafrost, and microbial mats, making it an excellent terrestrial alternative for studying potential past or present life on Mars.
