Q204. Read the following statements marked as Assertion and Reason (R). Choose the correct option.
Assertion (A): India is actively developing a Third Launch Pad (TLP) at the Satish Dhawan Space Centre (SDSC-SHAR).
Reason (R): The Third Launch Pad is specifically designed to significantly boost India's space launch frequency and accommodate larger, next-generation launch vehicles like NGLV.

  1. (a) Both A and R are true, and R is the correct explanation of A
  2. (b) Both A and R are true, and R is not the correct explanation of A
  3. (c) A is true, but R is false

Q290. Consider the following statements about the Polaris Dawn Mission and Van Allen Radiation Belts:
1. The Van Allen Belts consist of charged particles originating exclusively from the Sun.
2. The Polaris Dawn Mission studied the biological effects of space radiation by traveling through high-radiation zones around Earth.
3. Spacecraft passing through the Van Allen Belts must limit their transit time to reduce radiation exposure.
Which of the above statements is/are correct?

  1. (a) 1 and 2 only
  2. (b) 2 and 3 only
  3. (c) 1 and 3 only
  4. (d) 1, 2, and 3
Answer & solution

Answer: (b) 2 and 3 only

Correct Answer: Option 2 – Statements 2 and 3 only
Statement 1 is INCORRECT: Van Allen Belts consist of charged particles from BOTH the solar wind AND Earth's own magnetosphere (from cosmic ray albedo neutron decay). They do not originate 'exclusively' from the Sun.
Statement 2 is CORRECT: The Polaris Dawn Mission (SpaceX, September 2024) was notable for being the first commercial spaceflight to traverse the Van Allen Belts, and it studied biological effects of space radiation on the crew.
Statement 3 is CORRECT: Spacecraft minimize transit time through the Van Allen Belts to limit radiation exposure to crew and sensitive instruments.
Since statements 2 and 3 are correct and 1 is incorrect, the answer is Option 2.
