Bacteria to terraform Mars atmosphere and rock/soil
If life exists or could be engineered to survive on Mars, it would need to endure harsh conditions: extreme cold, low pressure, high radiation, and a thin CO₂-rich atmosphere. However, some extremophiles on Earth might provide clues about potential Martian organisms that could consume rocks (chemolithotrophy) and release oxygen.

Potential Bacteria for Mars
These bacteria could, in theory, survive and process Martian rocks to release oxygen:
a. Cyanobacteria (Oxygen-Producing Microbes)
Example: Chroococcidiopsis (found in deserts and Antarctica)
Can photosynthesize in extreme conditions and survive radiation.
Could potentially live in ice pockets or subsurface caves on Mars.
If placed in a controlled bioreactor with Martian regolith, it could help generate oxygen.
b. Iron and Sulfur-Oxidizing Bacteria
Example: Acidithiobacillus ferrooxidans
Extracts iron and sulfur from rocks, producing energy.
If engineered, it could potentially process Mars’ basaltic rocks and contribute to oxygen production.
c. Silicate-Weathering Bacteria
Example: Sphingomonas desiccabilis
Capable of breaking down basaltic rock for nutrients.
Could help release elements like magnesium and iron while potentially aiding in oxygen cycling.

Potential Fungi and Lichen for Mars
Lichen are symbiotic organisms (fungi + algae or cyanobacteria) that can endure extreme environments.
a. Lichen That Can Survive Martian Conditions
Example: Pleopsidium chlorophanum (Yellow Antarctic Lichen)
Tested in Mars simulation experiments and survived exposure to extreme UV, cold, and CO₂-rich air.
Can use minimal water to photosynthesize and produce oxygen.
b. Rock-Dissolving Fungi
Example: Black Yeast (Cryomyces antarcticus)
Can survive in dry, high-radiation environments.
Could break down minerals in Martian regolith.
