Liquid water on Mars refers to the presence of water in its liquid state on the surface or subsurface of the Martian planet. While Mars has a thin atmosphere and is known for its cold temperatures, certain conditions, such as seasonal temperature variations and the presence of salts, can allow water to exist as a liquid. Evidence suggests that liquid water may flow intermittently on the surface, particularly in the form of briny flows known as recurring slope lineae. Additionally, scientists have detected signs of ancient riverbeds, lake beds, and minerals that typically form in the presence of water, indicating that liquid water may have been more prevalent in Mars’ past. The study of liquid water on Mars is significant for understanding the planet’s geology, climate history, and potential for hosting microbial life, both in its past and potentially in present-day environments.
In a groundbreaking discovery, researchers have uncovered a vast reservoir of liquid water hidden beneath the surface of Mars. This underground ocean, situated between depths of 11.5 and 20 km,…
