Why in news
Texas A&M University and Aegis Aerospace are sending grape seeds to the ISS to study the impact of cosmic radiation on crop resilience as part of the TAMU-SPIRIT mission.
Background
The TAMU-SPIRIT mission involves sending hundreds of grape seeds to the International Space Station (ISS) for a six-month study. The experiment aims to analyze genetic changes and growth differences caused by exposure to cosmic rays compared to ground-based control seeds.
Facts for Prelims
- S&TTAMU-SPIRIT: A mission studying the effects of space radiation on plant genetics and crop resilience.
- PlaceInternational Space Station (ISS): A modular space station in low Earth orbit.
- FactStudy duration: 6 months of exposure to cosmic rays.
For Mains
Q. Discuss how space-based biological research can contribute to global food security and the development of climate-resilient agriculture.
Dimensions to cover in your answer
- Genetic adaptation: Potential for cosmic radiation to trigger mutations enhancing drought or heat tolerance in staple crops.
- Space-Agri synergy: Utilizing microgravity and radiation environments to accelerate plant breeding cycles beyond terrestrial limitations.
- Bio-security risks: Monitoring potential for unintended genetic alterations in crops during long-duration space exposure.
Keywords: Cosmic radiation · Crop resilience · Genetic modification · Space biology · Food security
