Space Food

Nutrient production

Mars has the nutrients for growing plants to survive on Mars! There may not be the right amount of nutrients depending on where astronauts land on the Red Planet,

Algae can also produce carbohydrates and protein.

Hydroponics

Hydroponics food production in space and on Mars looks promising.

Food requirements for use in space and on Mars will very and the diet will be challenging.

The first diet looks likely to initially include just vegetables, insects and them some chemical produced sauces and seasonings, hopefully when there is enough corn/wheat production there could be some experiments with livestock like chickens and fish.

Two other possible plants that have been tested are duckweed (Lemna minor) and water fern (Azolla filiculoides), as particularly suitable, and they grow on the surface of water.

Meat

Animals will not go to Mars until a fully developed agriculture is plentiful enough to support the feeding them.

One possibility maybe the production of artificial meat but current research is very power demanding.
