This means that Mars has lost a volume of water 6.5 times what is stored in today's polar caps. The water for a time would have formed an ocean in the low-lying Mare Boreum. The amount of water could have covered the planet about 140 meters, but was probably in an ocean that in places would be almost 1 mile deep. [1] [2]
The Mars Reconnaissance Orbiter's HiRISE instrument has taken many images that strongly suggest that Mars has had a rich history of water-related processes. A major discovery was finding evidence of hot springs.

Scientists discovered signs of an ocean's worth of liquid water miles below Mars' surface. The findings, based on Marsquake measurements by NASA's InSight lander, could help solve a mystery.
The Perseverance spacecraft landed on Mars in February 2021 and has been doing reconnaissance missions and looking for signs of life. NASA's Perseverance explores ancient Mars crater where water ...
After 1,000 days on the Martian surface, the Perseverance rover has collected samples that reveal the history of water within Jezero Crater. Perseverance rover uncovers intriguing new clues about ...
The images acquired by the Mariner 9 Mars orbiter, launched in 1971, revealed the first direct evidence of past water in the form of dry river beds, canyons (including the Valles Marineris, a system of canyons over about 4,020 kilometres (2,500 mi) long), evidence of water erosion and deposition, weather fronts, fogs, and more.

Mars 2020 is a NASA mission that includes the rover Perseverance, the now-retired small robotic helicopter Ingenuity, and associated delivery systems, as part of the Mars Exploration Program. Mars 2020 was launched on an Atlas V rocket at 11:50:01 UTC on July 30, 2020, [ 4 ] and landed in the Martian crater Jezero on February 18, 2021, with ...
