Gaganyaan Mission : Astronaut Safety
The recent return of NASA astronauts Sunita Williams and Barry Wilmore highlights the critical role of safety protocols in human spaceflight. ISRO is now prioritizing similar measures for its Gaganyaan mission.
- 3 Phases of Human Spaceflight – Launch, Orbit, and Re-entry.
- Each phase necessitates specific and stringent safety protocols to ensure astronaut well-being.
- Launchpad emergency measures – Drawing lessons from tragedies like the Apollo-1 fire, ISRO has implemented launchpad safety measures, including ziplines and fireproof lifts for rapid evacuation.
- Crucial emergency exit system – A key safety feature during launch is the emergency exit device. The human-rated launch vehicle incorporates a tower-like Crew Escape System for quick detachment of the crew module during emergencies.
- Crew escape system functionality – The Crew Escape System utilizes two motors: the Low-altitude Escape Motor (LEM) and the High-altitude Escape Motor (HEM), activating based on the altitude of the emergency. Pad aborts involve both motors for swift evacuation.
- Historical precedents – Incidents like the Soyuz T-10 launch abort and Blue Origin’s NS-23 mission underscore the proven effectiveness and vital importance of robust crew escape systems in safeguarding astronauts during launch emergencies.
