A: 1 and 2 only

B: 2 only

C: 2 and 3 only

D: 1, 2, and 3

Statement 2 is correct: It focuses on human behaviour, stress response, and teamwork.

Statement 3 is correct: The mission is conducted in Leh, Ladakh due to its high-altitude conditions.

Q2:

With reference to the Gaganyaan Mission, consider the following statements:

1.   It aims to send three astronauts into low Earth orbit.

2.   The mission duration is planned for about three days.

3.   It will use the PSLV launch vehicle.

Which of the statements given above is/are correct?

A: 1 and 2 only

B: 2 only

C: 2 and 3 only

D: 1, 2, and 3

Show

Answer: A

Explanation:

Statement 1 is correct: The Gaganyaan mission aims to demonstrate India's human spaceflight capability by sending a crew of three astronauts into a Low Earth Orbit (LEO) at an altitude of approximately 400 km.

Statement 2 is correct: The planned mission duration for the manned flight is approximately three days, after which the crew will safely return to Earth by landing in Indian sea waters.

Statement 3 is incorrect: The mission will NOT use the PSLV (Polar Satellite Launch Vehicle). Instead, it will use the LVM3 (Launch Vehicle Mark-3), also known as GSLV Mk III. The LVM3 is India’s heaviest and most powerful launch vehicle, which has been human-rated to meet safety requirements for carrying astronauts.

Q3:

Consider the following statements about ISRO:

1.   It was established in 1969.

2.   Its headquarters is in Bengaluru.

3.   It was founded by Dr. Homi J. Bhabha.

Which of the statements given above is/are correct?

A: 1 and 2 only

B: 2 only

C: 2 and 3 only

D: 1, 2, and 3

Show

Answer: A

Explanation:

The correct statements about the Indian Space Research Organisation (ISRO) are:

It was established in 1969: ISRO was established on August 15, 1969, replacing the earlier Indian National Committee for Space Research (INCOSPAR).

Its headquarters is in Bengaluru: The headquarters of ISRO is located in Bengaluru, Karnataka.

It was founded by Dr. Vikram Sarabhai: ISRO was founded under the leadership of Dr. Vikram Sarabhai, who is considered the father of the Indian space program. Statement 3, attributing the founding to Dr. Homi J. Bhabha, is incorrect; Dr. Bhabha is known as the father of the Indian nuclear program.

Therefore, only statements 1 and 2 are correct.

Q4:

With reference to the Artemis 2 Mission, consider the following statements:

1.   It is the first crewed lunar mission since the Apollo era.

2.   The mission involves landing astronauts on the Moon.

3.   It uses the Orion spacecraft.

Which of the statements given above is/are correct?

A: 1 and 2 only

B: 1 and 3 only

C: 2 and 3 only

D: 1, 2, and 3

Show

Answer: B

Explanation:

Statement 1 is correct: The Artemis II mission is the first crewed mission to the vicinity of the Moon since the Apollo era, which ended with Apollo 17 in 1972.

Statement 3 is correct: The mission utilizes the Orion spacecraft, launched atop the Space Launch System (SLS) rocket, to carry and sustain the crew during their journey.

Statement 2 is incorrect: Artemis II is a lunar flyby mission, not a landing mission. It is designed to test and validate critical systems in deep space without touching the lunar surface. The actual landing of astronauts on the Moon is planned for the subsequent Artemis III mission.

Q5:

With reference to the Prototype Fast Breeder Reactor (PFBR), consider the following statements:

1.   It is located at Kalpakkam, Tamil Nadu.

2.   It uses enriched uranium as fuel.

3.   It uses liquid sodium as coolant.

Which of the statements given above is/are correct?

A: 1 and 2 only

B: 2 only

C: 1 and 3 only

D: 1, 2, and 3

Show

Answer: C

Explanation:

Statement 1 is correct: The Prototype Fast Breeder Reactor (PFBR) is located at Kalpakkam, Tamil Nadu, within the Madras Atomic Power Station complex.

Statement 3 is correct: It uses liquid sodium as a coolant because sodium has excellent heat transfer properties and does not slow down neutrons, which is essential for the "fast" neutron spectrum required in breeder reactors.

Statement 2 is incorrect: The PFBR does not use enriched uranium as its primary fuel. Instead, it uses Mixed Oxide (MOX) fuel, which is a blend of Plutonium-239 (fissile material) and Uranium-238 (fertile material). The reactor is designed to "breed" more Plutonium-239 from the Uranium-238 blanket during operation.
