Mission Focus

Future Mars missions are likely to target the mid-latitude icy zones, where subsurface conditions may support life, providing key areas for exploration.

Dust Balance

The amount of dust in Martian ice is critical. Too much dust blocks sunlight, but the right balance could create a zone capable of supporting photosynthetic life.

Habitable Depths

Research published in the journal Communications Earth & Environment shows that photosynthetic life on Mars could exist between 5 to 38 centimeters deep in dusty ice or up to 3.10 meters deep in cleaner ice, avoiding harmful radiation.

Water Pockets

Dust particles in the ice could cause localized melting, providing liquid water up to 1.5 meters deep, potentially creating suitable conditions for life to survive.

Prime Regions

Mars’ mid-latitude regions, between 30 and 50 degrees latitude, are considered optimal for life, offering the right conditions for subsurface melting and habitable zones.

Life Potential

While these icy zones could theoretically support photosynthetic life, there is no confirmed evidence yet. They represent promising targets for future exploration.

Key Targets

Exposed ice in Mars’ mid-latitudes may serve as critical areas for future life-detection missions, where conditions could support the search for extraterrestrial life.
