Dangers of Space Travel: Insights from NASA Expert – Episode 55

Swift Summary

• Astronauts face multiple dangers during space exploration,starting with the risk of launching on a rocket.
• Radiation poses a significant threat in space, including solar particles and galactic cosmic rays that can damage DNA. Space vehicle shielding provides some protection against this.
• Microgravity impacts bone and muscle health, requiring astronauts to exercise for hours daily to mitigate these effects.
• Supplies like food are crucial for long missions to ensure astronauts’ sustenance throughout their journey.
• NASA has been making preparations to address these challenges and ensure the safety of its astronauts during missions.

Indian Opinion Analysis

Human space exploration highlights unique challenges such as radiation exposure, microgravity effects, and logistical concerns like food sustainability-issues requiring continuous technological advancement. While India’s own space ambitions (e.g., Gaganyaan) include plans for crewed missions in low-Earth orbit zones initially less impacted by galactic rays compared to deep-space travel, lessons from global efforts remain vital as ambitions grow toward interplanetary goals.

Radiation management and astronaut health advancements showcased by agencies like NASA could serve as benchmarks or partnership opportunities for ISRO’s evolving programs while mitigating future risks in prolonged mission planning.
