Summary:
- Cyanobacteria, also known as blue-green algae, could be a key ingredient in fertilizers that could help grow plants on Mars.
- Researchers have found that cyanobacteria can be used to create a nutrient-rich soil that can support plant growth in Martian-like conditions, including low gravity and high radiation.
- This discovery could be a significant step towards establishing a sustainable human presence on Mars, as it would allow astronauts to grow their own food using local resources.
