Mars' Water Mystery: New Discoveries Reveal Ancient Oceans, Groundwater & Disappearance

• NASA rovers Curiosity and Perseverance found evidence of ancient groundwater and beaches on Mars, suggesting water existed earlier and longer than thought.
• Perseverance discovered ancient beaches in Jezero Crater with wave-like limestone layers and rounded sand grains, indicating a lake 3.5 billion years ago.
• Curiosity observed spider web-like structures on Mount Sharp, formed by groundwater flowing through rock cracks, suggesting water was present in Mars' early days.
• A recent study indicates a severe dust storm in 2022-2023 carried water vapor into the upper atmosphere, leading to increased hydrogen escape and water loss into space.
• Scientists hope to drill into Martian ice in future missions to search for microorganisms and determine if water still exists inside the planet.
