Space food: How can we advance existing technologies?

Humanity’s ambitions are extending beyond space exploration toward a sustained presence in space. In turn, human spaceflight is gaining momentum, driven by space agencies, academia and commercial actors, a trend known as “the spaceflight boom” of the 21st century.

Missions to the Moon and eventually, Mars are no longer symbolic milestones but operational programmes requiring ongoing infrastructure, logistics and human-system integration.

At its March 2026 “Ignition” event, NASA reinforced this transition by outlining a phased approach to lunar surface operations, prioritizing repeatability, infrastructure development and long-duration mission capability. This includes fewer isolated missions and a shift toward a sustained lunar cadence, with more frequent missions and eventually regular crewed landings.

In parallel, the China National Space Administration and Roscosmos are advancing the International Lunar Research Station. This shows that multiple global powers are pursuing their own long-term lunar strategies, rather than a single coalition, as has been the case.

The implication is that the Moon is now serving as a “gateway to deep space,” where spaceflight must operate reliably and sustainably.

Food is a determining factor in a successful long-duration human spaceflight. Continued reliance on pre-packaged foods transported from Earth becomes increasingly restrictive as mission duration and distance increase. Resupply is costly, logistically fragile and constrained by launch reliability. At the same time, shelf-stable food systems degrade in nutritional quality, variety and sensory appeal.

Food is not only a matter of caloric intake; it directly affects crew health, cognitive performance, psychological stability and social cohesion. In isolated and extreme environments, these are primary operational factors. For sustained lunar presence and future Mars missions, the challenge is therefore to develop integrated food systems that are:

Locally produced food, combined with selective resupply, is thus increasingly seen as a necessary evolution.

Simultaneously, space-based research is beginning to demonstrate terrestrial relevance. Experiments on plant growth in microgravity, followed by cultivation on Earth, suggest potential pathways for developing more resilient crops under stress conditions.

For example, grapevine samples exposed to microgravity aboard the International Space Station have shown altered responses to disease, pointing to the possibility of engineering hardier plant varieties.

These insights are directly relevant to terrestrial challenges such as:

However, these findings remain operationally underdeveloped, with no clear pathway to deployment at scale.

Food production and distribution operate as complex socio-technical ecosystems. As well as by biology and engineering, they are shaped by infrastructure, regulation, markets, cultural practices and operational realities. Much of this expertise resides outside the space sector.

As a result, the relationship between space and Earth should be framed as a two-way innovation system in which space provides extreme test conditions, while terrestrial sectors provide the knowledge required to scale, regulate, and implement solutions.

Despite growing activity, progress remains fragmented. Key enabling technologies are advancing but not yet integrated into viable systems. These include:

The challenge is therefore system integration, reliability and operational validation.

Advancing the development of space food systems requires an operational framework that distinguishes:

Such a framework would enable cross-sector engagement necessary for more resilient and sustainable spaceflight.

Addressing this gap requires deliberate coordination. Terrestrial actors across agriculture, food processing, biotechnology, and regulatory systems must be engaged as core partners in shaping research agendas, defining use cases, and building implementation pathways.

Policy plays a central role in enabling this shift. Today, companies conducting in-space research face multiple regulatory uncertainties, including:

Emerging efforts are addressing this. In the United Kingdom, collaboration between the Medicines and Healthcare products Regulatory Agency, the UK Space Agency and other stakeholders is developing regulatory pathways for space-manufactured biologics.

Such models illustrate how regulatory innovation can reduce uncertainty, enable commercialization and create credible pathways from experimentation to deployment.

For space food systems to evolve into an operational capability, it will require deliberate coordination and must remain confined to fragmented experiments with limited real-world impact. The strategic value lies in treating space as a high-constraint development environment, where solutions are designed for reliability, integration and deployment from the outset.

Realizing this requires moving beyond isolated research efforts and toward:

The opportunity is not only to support human life beyond Earth but also to strengthen food systems on Earth. One focus of the Centre for Space Futures’ cross-sector initiative is to build bridges between the space and terrestrial sectors to inform the life sciences.

The question has shifted from the technical feasibility of space food systems to whether they will be developed as an integrated, cross-sector priority or remain an underutilized niche at the margins of both space and terrestrial innovation.
