सारांश

As India prepares for the Gaganyaan mission, human-rating emerges as a critical process to ensure the safety of astronauts. Human-rating involves rigorous engineering and certification to minimize risks in space systems like the LVM-3 rocket. This includes adding redundant systems, robust abort capabilities, and extensive testing.

While launch vehicles have high success rates, carrying humans demands a lower risk tolerance. ISRO is upgrading and certifying the LVM-3 for human-rating, incorporating backup systems and a fast crew escape system to align with India's strategic goal of self-reliance in human spaceflight.

पृष्ठभूमि

Human spaceflight programs globally, including those of the USA, Russia, and China, have emphasized rigorous safety protocols and engineering standards. The concept of 'human-rating' evolved from early space race experiences and the need to minimize risks to astronauts.

नवीनतम घटनाक्रम

India's Gaganyaan mission necessitates human-rating of the LVM-3 rocket, involving system redundancy, abort mechanisms, and extensive testing. ISRO is actively upgrading and certifying the LVM-3 for this purpose.

बहुविकल्पीय प्रश्न (MCQ)

1. Consider the following statements regarding the 'human-rating' process in the context of space missions: 1. It primarily focuses on enhancing the comfort and living conditions for astronauts during spaceflight. 2. It involves rigorous engineering and certification processes to minimize risks to human life in space systems. 3. Redundancy in critical systems is a key aspect of human-rating to ensure mission safety. Which of the statements given above is/are correct?

  • A.1 and 2 only
  • B.2 and 3 only
  • C.1 and 3 only
  • D.1, 2 and 3
उत्तर देखें

सही उत्तर: B

Human-rating is primarily about minimizing risks to human life, not just comfort. Redundancy is a key component.

2. In the context of the Gaganyaan mission, what is the primary purpose of incorporating a 'fast crew escape system' into the LVM-3 rocket?

  • A.To allow astronauts to quickly return to Earth in case of minor discomfort during the mission.
  • B.To provide a rapid and safe method for astronauts to evacuate the spacecraft in the event of a launch anomaly or emergency.
  • C.To enable astronauts to conduct extravehicular activities (EVAs) more efficiently.
  • D.To facilitate the deployment of scientific payloads during the mission.
उत्तर देखें

सही उत्तर: B

The fast crew escape system is a critical safety feature designed for emergency situations during launch.

3. Which of the following statements is NOT correct regarding the LVM-3 rocket being used for the Gaganyaan mission?

  • A.It is being upgraded and certified for human-rating by ISRO.
  • B.It will be the first Indian rocket to carry humans into space.
  • C.It is designed to be a fully reusable launch vehicle.
  • D.It incorporates redundant systems to enhance reliability.
उत्तर देखें

सही उत्तर: C

The LVM-3 is not designed to be fully reusable. While some components may be recovered, it's not a fully reusable system like SpaceX's Falcon 9.

4. Assertion (A): Human-rating of launch vehicles is crucial for ensuring the safety of astronauts during space missions. Reason (R): The risk tolerance for human spaceflight is significantly lower than that for unmanned missions due to the potential for loss of life. In the context of the above statements, which of the following is correct?

  • A.Both A and R are true, and R is the correct explanation of A.
  • B.Both A and R are true, but R is NOT the correct explanation of A.
  • C.A is true, but R is false.
  • D.A is false, but R is true.
उत्तर देखें

सही उत्तर: A

Both the assertion and the reason are true, and the reason correctly explains why human-rating is essential.
