Q. Consider the following statements:
1.The CE20 cryogenic engine is an advanced propulsion system developed by ISRO.
2.A human rating of a spacecraft highlights the functionality of on-board scientific instruments.
Which of the statement(s) given above is/are correct?
Explanation –
Statement 1 is correct. The CE20 cryogenic engine is an advanced propulsion system developed by the Indian Space Research Organisation (ISRO). It is a powerful upper-stage engine that uses liquid hydrogen and liquid oxygen as propellants and operates at extremely low temperatures. The CE20 engine has significantly enhanced India’s capability to launch heavier payloads into space.
Statement 2 is incorrect. The term “human rating” of a spacecraft refers to the certification process that ensures the spacecraft is safe and reliable for transporting humans. This involves evaluating various factors such as life support systems, crew safety features, environmental control systems, and structural integrity, among others.
