ISRO Gaganyaan Astronaut Cadre to Civilians

Why in News?

Recently, ISRO’s Committee on astronaut selection and management recommended opening its Gaganyaan astronaut cadre to civilians for the first time alongside military pilots, marking a major shift for future Gaganyaan missions.

Highlights of ISRO Committee on Astronaut Selection and Management Report 

• Selection Recommendation: The committee proposed a pool of 10 candidates for the upcoming Gaganyaan Mission’s second batch. 
  • This group will consist of six mission pilots from military backgrounds and four civilian specialists. 
  • This marks the first official inclusion of civilians in the astronaut cadre. 
  • The four civilian members will be recruited from STEM fields. However, the official selection criteria have not been announced yet.
  • Experts in science, technology, engineering, and mathematics are preferred. 
  • These individuals will focus on scientific research and experiments during orbital flights.
  • For the third batch, the committee recommends 12 astronauts. The ratio will shift drastically to include ten civilian specialists and only two pilots.
• Pilot Expansion: The military intake will also be broadened beyond fighter pilots. The committee recommends including combat helicopter pilots from the Indian Air Force. This expansion aims to utilize a wider range of aviation experience.
• Readiness Timeline: A full cycle of selection and training is estimated to take 4.5 years or 72 months. The committee targets readiness for the second batch within this timeframe. A third batch is projected to be ready within 96 months.
• Cadre Strength: The committee envisages creating a total astronaut cadre of up to 40 individuals. As per the project 26 individuals will be selected. 
  • A large pool helps manage attrition and long-term uncertainties. It also allows for international mission opportunities.
• Flight Priority: Mission pilots will lead early safety-critical flights to ensure system maturity. 
  • Civilian specialists are tentatively scheduled to fly starting from the fourth mission.  
• Mission Frequency: Planning assumptions suggest a target of two human spaceflight missions every year. 
  • Individual astronauts may return to space after a gap of approximately two years. This requires a sustained and growing pool of active personnel. 
• Crew Augmentation: The crew size is proposed to increase from two to three astronauts. 
  • This change is planned to take effect from the seventh mission onward. It will be enabled by upgrades to the crew module capacity. 

Significance of Civilian Inclusion

• Scientific Specialisation: Civilian inclusion can bring domain experts into the mission profile. The inclusion of STEM specialists may bring deep expertise in biotechnology and fluid physics. 
  • These civilians could focus entirely on microgravity research while pilots handle flight systems. 
  • These specialists improve in orbit experiments and system analysis. It enhances mission output beyond piloting functions.
• Station Operations: India plans to launch the Bharatiya Antariksh Station by 2035. A permanent station needs Mission Specialists for maintenance and research.
  • Civilians can serve as the primary residents of this orbital laboratory. They can manage complex payloads and perform long-duration experiments.
• Sustaining Cadre: ISRO aims for a total cadre of 40 astronauts. Relying only on IAF test pilots is not sustainable for long-term needs. 
  • Adding civilians expands the recruitment base significantly. It ensures a steady supply of Gaganyatris for future annual missions.
• Diversity Benchmarks: The civilian track opens more opportunities for women scientists in space. Currently the military pilot pool has very few eligible candidates.
  • Civilian recruitment allows ISRO to achieve better gender representation. This aligns with global standards set by NASA and ESA.
• Economic Potential: Civilian astronauts can represent private industries or research institutes. This encourages commercial participation in the space sector. 
  • It paves the way for space tourism and private research missions. This will eventually reduce the financial burden on the national budget.
• Global Integration: Most international missions involve multidisciplinary teams. Including civilians makes India a better partner for joint missions. 
  • It allows Indian researchers to participate in projects on the International Space Station. This can foster deeper international cooperation in space exploration.

Challenges

• Environmental Control & Life Support (ECLSS): Civilians have lower physiological tolerance for the extreme temperature variations and radiation of space compared to trained military pilots. Developing reliable, earth-like life support systems remains a critical technological gap.
• Infrastructure & Facility Gaps: India currently operates only temporary training centers and lacks advanced domestic facilities like human centrifuges or zero-gravity simulators. This necessitates continued reliance on international partners for rigorous preparation.
• Medical & Bioastronautics Challenges: Civilians are more susceptible to the psychological and physical stresses of zero-gravity, including depression, radiation exposure, and psychiatric disorders.
• Technical Benchmarking: ISRO must establish clearer cognitive and physical benchmarks to transition from training highly specialized test pilots to broader civilian researchers.
• Space Debris & Safety: The increasing threat of space debris poses a risk of cabin depressurisation. Ensuring the reliability of Crew Escape Systems (CES) is paramount for civilians who may lack the rapid emergency response instincts of fighter pilots.
