NASA | Measuring Mars' Ancient Ocean

The video explores Mars' ancient climate, suggesting it was once warmer and wetter. NASA researchers used infrared telescopes to study water molecules in Mars' atmosphere, revealing significant water loss over time. The findings indicate that only 13% of an ancient ocean remains, with 87% lost to space. This ocean once covered 20% of Mars' surface, comparable in depth to the Mediterranean Sea. The study suggests Mars was habitable for longer than previously thought, expanding the potential for ancient life.
