Scientists are developing artificial photosynthesis to grow food on Moon and Mars

 In a game-changing technological breakthrough, scientists are creating artificial photosynthesis devices that astronauts will use on future space missions. 




On our lush and abundant planet Earth, the wide variety of plant species generously churns out all the oxygen our lungs crave. But once we step beyond the confines of our world, into the vast openness of space, such as the International Space Station or the lunar landscape, we’re left to fend for ourselves. Producing our own oxygen on space journeys becomes a critical necessity.


It is with this survival imperative in mind that novel devices are under active development, ones that seek to emulate the miraculous process of photosynthesis found in our plant kingdom. These devices ingeniously use sunlight and water to generate oxygen.

As it stands today, electrolysis is the primary technique for extracting oxygen from water, but this method relies heavily on the availability of electricity. Taking a leaf out of nature’s book, these new devices work differently. 

Coating semiconductor materials with metallic catalysts, these artificial photosynthesis systems create oxygen from water and sunlight, effectively sidestepping the need for electricity.

“Water has been detected on the Moon and on Mars. This study is a significant stepping stone in devising an alternative apparatus to supply future space explorers with fresh oxygen,” explained Brigitte Lamaze, an environmental control and life support engineer at ESA. 

“Finding more efficient and environmentally-friendly ways to mimic parts of Earth’s atmosphere using available resources is a promising stride towards our goal of constructing a complete ecosystem within a box.”



At ESA, we’re ceaselessly driving the limits of our theoretical knowledge in pursuit of superior technology. This study showcases one such leap in understanding the developments necessary for pioneering space technologies,” noted ESA engineer Christel Paill


Scientists are indeed exploring the concept of artificial photosynthesis as a potential method for growing food on the Moon and Mars. Artificial photosynthesis is a technology inspired by the natural process of photosynthesis that occurs in plants, where sunlight is used to convert carbon dioxide and water into oxygen and glucose (a form of sugar) as a source of energy. In the context of space exploration and colonization, artificial photosynthesis offers several advantages. Firstly, it allows for the generation of oxygen, which is crucial for sustaining human life. Oxygen is needed for breathing, and it can also be used in the production of rocket fuel or as a propellant for future space missions. Secondly, artificial photosynthesis can provide a sustainable source of food. By utilizing sunlight and converting carbon dioxide from the lunar or Martian atmosphere, the technology could generate glucose or other forms of carbohydrates that could serve as a nutritional source for astronauts or future settlers. Additionally, the byproduct of this process, oxygen, could be used to support the growth of plants or provide breathable air within enclosed habitats. The development of artificial photosynthesis for extraterrestrial environments poses several challenges. Unlike on Earth, the Moon and Mars have different atmospheric compositions, surface conditions, and available sunlight. #ArtificialPhotosynthesisInSpace #FoodProductionBeyondEarth #SustainableLifeSupport #GrowingFoodOnMoonAndMars #PhotosynthesisForSpaceColonization #SpaceFarming #OxygenGenerationInSpace #SustainableAstronautHabitats #FutureFoodSecurity
