While the United States is planning a long-term mission to the Moon under the Artemis program, one of the biggest challenges scientists face is what astronauts will eat in space. This challenge has prompted researchers to explore whether it is possible to grow crops directly using materials found on the moon.A recent study by researchers from the University of Texas at Austin and Texas A&M University provides an important step toward this goal.In research published in the journal Scientific Reports, scientists successfully grew and harvested chickpeas in simulated “lunar soil,” also known as simulated lunar regolith. Sarah Santos, the project’s lead researcher, said this work represents a big step towards understanding what food can be grown on the moon and what future lunar explorers can eat.
How scientists grew chickpeas in a simulation of lunar soil
Researchers from Texas A&M University and the University of Texas at Austin used simulated lunar regolith, or simulated lunar soil, to test whether crops could grow on the moon. This material is designed to replicate the chemical composition and physical structure of soil found on the Moon.Unlike the composition of Earth’s soil, lunar regolith is devoid of organic matter, microorganisms or essential nutrients required primarily for plant growth.
To create a suitable environment for growing plants, the lunar soil composition was mixed with organic compost known as vermicompost, which is a byproduct of earthworms.The chickpea plant formula has also been subjected to arbuscular mycorrhizal fungi, which are beneficial microorganisms that help the plant acquire necessary nutrients while withstanding adverse conditions.Several soil mixture formulations were tested, and results indicate that chickpea plants are able to thrive in the moonshine formulation when exposed to organic fertilizer.
Why were chickpeas chosen for? Space farming
The reason chickpeas were chosen for space farming is that they provide high nutritional value to astronauts. Chickpeas are high in plant protein, fiber, and vitamins such as iron and folate.Chickpeas are also known for their ability to grow in dry environments. They are typically grown in semi-arid regions and can withstand water stress and harsh conditions.Chickpeas are also a legume. Legumes interact with nitrogen-fixing bacteria in their roots.
This biological process converts atmospheric nitrogen into forms that plants can absorb and contribute to soil fertility.
What the results mean for future lunar missions
Growing chickpeas in simulated lunar soil provides data relevant to space exploration, especially for missions that NASA plans to send in the near future under the Artemis program. In order to allow astronauts to stay on the moon for a longer period, the ability to produce their own food should be achieved.
This study shows that plants can survive in lunar soil using organic matter and microbes.Although the study indicates that plants can survive in lunar soil, the soil contains certain components that are harmful to the survival of plants.In addition, the Moon has no atmosphere, constant temperature, or natural water. However, the future focus should be on developing and implementing a controlled form of agricultural practices, such as greenhouses, which will be able to provide the necessary conditions needed for plants to survive in lunar soil.
