"Massive 2-Mile Thick Water Ice Deposit Discovered at Mars' Equator"

The European Space Agency's Mars Express mission has discovered a substantial amount of water ice buried beneath Mars' equator, measuring up to 2.3 miles thick and extending 3000m underground. This finding challenges previous assumptions about the planet's geology and climate history, suggesting that Mars may have had a different climate in the past due to variations in its axial tilt. The ice, heavily contaminated by dust, is difficult to access but could provide valuable resources for future crewed missions.
