This is huge!

Spirulina, a type of algae, is considered one of the best sources of food on Mars, because it can grow in small containers and doesn't need big greenhouses. It is also very nutrient-rich, containing both lots of energy and protein.

However, vitamin B12 so far has been assumed to only exist in animal food products, such as beef and dairies.

This research project investigates genetically modified spirulina algae that contain levels of B12 comparable to beef!

This is not only a big breakthrough for food security on Mars but it also opens up the door another step to the broader approach of genetically engineering food sources on Mars. What might be next?
