Reservoir of liquid water found deep in Martian rocks

Scientists have discovered a reservoir of liquid water beneath the Martian crust, marking the first identification of liquid water on the planet. This finding is based on data from NASA's Mars Insight Lander, which operated from 2018 until its mission concluded in December 2022. The lander recorded seismic activity on Mars, and by analyzing the seismic waves, researchers identified signals indicative of liquid water located approximately six to twelve miles (10 to 20 km) deep in the crust. This discovery is significant for understanding Mars' water cycle and its climatic evolution, as well as addressing the long-standing question of the planet's water loss over billions of years. While there is evidence of ancient rivers and lakes on the surface, Mars has been largely arid for the past three billion years. The researchers suggest that if similar reservoirs exist across the planet, there could be enough liquid water to cover the surface with a layer over half a mile deep. However, accessing this water would be challenging due to its depth, complicating potential colonization efforts. The presence of liquid water also raises the possibility of habitable environments on Mars, which could be crucial for the search for extraterrestrial life.
