POEM-4: A New Frontier in Astrobiology and Space Research

What is POEM-4?

POEM stands for PSLV Orbital Experimental Module. It is the repurposed fourth stage of the Polar Satellite Launch Vehicle (PSLV). Instead of being discarded as space debris, the POEM platform is utilized to conduct experiments in the real space environment. POEM-4 will carry three biological experiments aimed at studying how life operates in outer space.

What Experiments are Being Conducted?

Several intriguing experiments will be flown aboard POEM-4:

• Spinach Cells: Scientists from Amity University, Mumbai, will investigate how spinach cells function in microgravity. This research could provide insights into the potential for growing food in space for future missions.
• Gut Bacteria: Undergraduate students from RV College of Engineering, Bengaluru, are sending gut bacteria (Bacteroides thetaiotaomicron) to space to study its growth and gene regulation in microgravity. This has important implications for understanding human physiology in a space environment.
• Cowpea Seeds and Leaves: An ISRO team from VSSC, Thiruvananthapuram, will explore how cowpea seeds and leaves germinate in microgravity through the CROPS module. This research will help clarify how plants grow in space and how to address challenges such as disorientation in seedlings.

Why is This Significant?

POEM-4 represents a pivotal step in various areas:

• First Step in Astrobiology: This project marks ISRO's first dedicated foray into astrobiology, signaling a new chapter in India’s space exploration endeavors.
• Gaganyaan and Future Missions: The findings from these experiments will be essential for upcoming human spaceflight missions, including Gaganyaan and the planned Indian space station.
• Promoting Innovation: By offering the POEM platform to startups and researchers, ISRO is fostering broader participation in space research and encouraging innovation.

Overall, POEM-4 signifies a small yet crucial step toward comprehending how life behaves in space, laying the groundwork for more ambitious biological experiments in the future.
