What will People Eat on Mars?

Think about your current diet: how much cheese, milk, eggs, and factory-farmed meat do you eat? If you're vegetarian or vegan, imagine the water and energy needed to irrigate and harvest all those crops. Can these eating habits be transplanted to Mars? Can they be sustained on Earth?

On Mars, plants cannot be grown outdoors, and there won’t be any animals roaming around, at least for now. Water will be scarce. Will martian citizens be forced to import all their food from Earth? How long could you put up with instant coffee and reconstituted spaghetti?

Faced with these questions, we wrote a paper on how to achieve food self-sufficiency for one million people on Mars by producing plants, insects and cell-based (or cultured) meat, drawing heavily on local resources.

The Martian Diet

You can start eating like a Martian today! Well, sort of. Cell-based meat products are not on grocery store shelves yet, but a host of companies are working on making it happen within 1-2 years, while others are introducing dozens of insect-based products to North America and Europe.

The “Martian Diet” offers environmental and ethical benefits over traditional Western habits: no mass suffering of caged animals, and sharp cuts in land, water, energy use, and carbon emissions.

1. Plants

Most plants grown on Earth can likely be grown on Mars too, either with hydroponics or in appropriately fertilized martian soil. Plants will need to be grown indoors with LED lighting, and yields can be greatly increased by ramping up CO2 and light levels. Genetic modification will be used heavily.

To eat plants like a Martian:

  1. Favor low water-use plants such as beans, tomato and potato rather than water hogs like almonds (and almond milk).
  2. Embrace GMO plants. Those approved in the USA include squash, soy beans, corn, papayas, sugar beets, potatos and apples. In 2018, Golden Rice, modified to synthesize beta-carotene, was approved for sale.
  3. On Mars, nothing will be “natural” or “organic”; buying these products may make us feel good, but organic practices are not efficient for feeding large populations.

2. Cell-based Foods

Cell-based meat

Cell-based meat, or cultured meat, is made from animal cells and involves no suffering or slaughter. Currently there are no cell-based meat products for sale, but they are much closer than you might think. Stay tuned to this page for updates in the next year or two. While you wait, try to get your hands on offerings from Impossible and Beyond Meat, available in an increasing number of grocery stores.

The table below shows the status of companies offering cell-based meat or fish products. Also consult the New Protein Landscape for a more comprehensive look at the broader ecosystem of players.

Single-cell Proteins

Single-cell proteins (SCP) are edible organisms made up of single cells, like fungi or algae. They can be mass-produced in bioreactors or fermentation tanks using appropriate nutrient solutions, and can provide rich sources of protein and fiber without the cholesterol and fat content of some meats.

The table below shows the status of companies offering SCP products.

3. Insects

Eating bugs is gross, right? Tell that to the 2 billion people in 80% of countries on Earth who consume almost 2000 species of edible insects. Turns out North Americans and Europeans are the odd ones out here. Insects provide vastly more calories per square meter than traditional protein sources, and insect flours can be used in regular recipes if you don’t want to crunch down on exoskeletons.

Whole insect products & flours

The table below lists insect-based products that are available for purchase, either in stores/restaurants or online. The first table features companies producing products where insects are front and center, either whole or ground into flours.
