Lab-Grown Food: Pioneering the Future of Space Cuisine

Imagine astronauts dining on steak, mashed potatoes, and desserts, all cultivated directly from individual cells in the vacuum of space. This vision is a step closer to reality following the launch of a groundbreaking experiment designed by the European Space Agency (ESA).

The initiative aims to investigate the feasibility of producing lab-grown foods in space, amidst the challenges posed by low gravity and heightened radiation levels found beyond our planet. ESA is funding this research as part of a larger strategy to streamline the cost of providing sustenance for astronauts, which currently can reach astronomical figures—upwards of £20,000 daily.

This experiment is seen as a foundational step toward establishing a small pilot food production facility aboard the International Space Station (ISS) within the next couple of years. According to Dr. Aqeel Shamsul, CEO of Bedford-based Frontier Space, the implications of successful lab-grown food production could be revolutionary for humanity’s ambitions to become a multi-planetary species.

“Our aspiration is to set up manufacturing facilities both in orbit and on the Moon,” Dr. Shamsul said, emphasizing the need for sustainable infrastructure that facilitates human habitation and labor in outer space.

Cost and Complexity of Space Nutrition

Astronauts are accustomed to the challenges of consuming freeze-dried foods in microgravity, which often leaves much to be desired in terms of taste and variety. Lab-grown food production represents a significant shift in how astronauts could maintain their diets, creating ingredients like protein, fat, and carbohydrates within controlled environments such as bioreactors.

Countries like the US and Singapore have already begun selling lab-grown chicken, while lab-grown steak is on the cusp of regulatory approval in the UK and Israel. On Earth, the environmental advantages of lab-grown food, such as reduced land use and lower greenhouse gas emissions, are promising. However, in space, the primary incentive is cost reduction, which could render the transportation of food to astronauts much more economical.

NASA and other organizations envision a long-term human presence on the Moon and potentially Mars, prompting the need for substantial food supplies for larger crews of astronauts. Dr. Shamsul points out that relying on traditional methods of food transportation for hundreds of astronauts would be fiscal folly.

“Growing food in space simply makes more sense,” he asserted, describing a process that could evolve from creating simple protein-enriched dishes to complex meals made with 3D-printed lab-grown ingredients.

The Science Behind Lab-Grown Food

Dr. Shamsul illustrated the possibilities with the concept, noting how technologies resembling those in science fiction narratives may soon find a foothold in reality. At the Bezos Centre for Sustainable Proteins at Imperial College in London, Dr. Rodrigo Ledesma-Amaro oversees the precision fermentation process used to produce food elements through genetically engineered yeast.

“We can synthesize the entire spectrum of food components—proteins, fats, carbohydrates, and fibers,” Dr. Ledesma-Amaro explained, indicating the adaptability of these technologies to create a wide variety of dishes.

A compact bioreactor mimicking this process was recently launched aboard a SpaceX Falcon 9 rocket as part of the ESA mission. While there is confidence in the potential for success based on Earth-based results, the real test will be whether these processes can be replicated in the unique conditions of space.

This initial trial will involve sending a small yeast sample into orbit and returning it to Earth to assess its viability. The findings from this mission are pivotal for the design of a larger and more advanced bioreactor expected to be sent to space next year.

However, the appearances of the bioreactor’s contents—a doughy, brick-colored mixture—may not be the most visually appealing, probably even less so than the current freeze-dried options available to astronauts.

Culinary Innovations in Space

To tackle this aesthetic challenge, Imperial College’s culinary strategist, Jakub Radzikowski, is charged with transforming the biochemical outputs into palatable dishes. Although he can’t yet use lab-grown ingredients due to pending regulations, he is experimenting with starches and proteins derived from natural fungi to develop recipes that could one day recreate familiar global cuisines in space.

“Our goal is to prepare dishes that provide comfort to astronauts from various cultural backgrounds,” Radzikowski noted, aiming to replicate the diversity of Earth’s culinary traditions, from French to Indian cuisines.

During a tasting session of spicy dumplings, former astronaut and UK’s first astronaut, Helen Sharman, contributed her expertise. “These are absolutely gorgeous!” she remarked enthusiastically, commending the flavor and texture of the dishes.

Reflecting on her own space food experience, Dr. Sharman noted the monotony of traditional long-life rations, highlighting the potential benefits of a diverse diet made possible by lab-grown foods. Research indicates that astronauts often experience nutritional adjustments during extended missions, which could be mitigated through the customization of lab-grown meals.

“In space, the ability to prepare and consume freshly cooked meals could significantly enhance the psychological well-being of astronauts,” she said, illustrating the dual importance of nutrition and morale during missions.
