Why in news
Scientists from the University of Texas at Austin and Texas A&M University successfully grew chickpeas in simulated lunar soil, suggesting a viable food production method for the Artemis program.
Background
The study, published in Scientific Reports, demonstrated that chickpeas thrived in a mixture of lunar regolith simulant and organic compost. The addition of arbuscular mycorrhizal fungi was crucial for aiding nutrient acquisition in the simulated lunar soil.
Facts for Prelims
- S&TLunar regolith simulant: Simulated moon soil used to test plant growth.
- S&TArbuscular mycorrhizal fungi: Fungi used in the study to assist chickpea nutrient acquisition.
- FactArtemis program: The NASA program mentioned as the context for long-duration lunar missions.
- S&TControlled agricultural practices: Use of greenhouses to provide stable conditions for plant survival on the Moon.
For Mains
Q. Discuss the technological and biological challenges of establishing extraterrestrial agriculture for long-duration space missions and its significance for human space exploration.
Dimensions to cover in your answer
- Nutrient limitation: Requirement of organic compost and mycorrhizal fungi to overcome regolith mineral deficiencies
- Atmospheric constraints: Necessity of pressurized greenhouse environments to maintain stable temperatures and CO2 levels
- Logistical trade-offs: Balancing the weight of organic inputs against the benefits of in-situ food production
Keywords: In-situ resource utilization · Space agriculture · Lunar regolith · Artemis program · Mycorrhizal fungi
