Q. With reference to the Polarimetry to Unify the Corona and Heliosphere (PUNCH) mission, consider the following statements:
1.It is a constellation of two small satellites that work together to create a wide-field view of the Sun’s inner chromosphere.
2.It is expected to improve our understanding of space weather phenomena.
Which of the statement(s) given above is/are correct?

[A] 1 only

[B] 2 only

[C] Both 1 and 2

[D] Neither 1 nor 2

Answer: B

Notes:

Explanations –

Statement 1 is incorrect. The Polarimetry to Unify the Corona and Heliosphere (PUNCH) mission is not a constellation of two satellites, but rather a constellation of four microsatellites. These four suitcase-sized satellites, each weighing about 64 kg, will work together to create a wide-field view of the Sun’s corona and the inner heliosphere.

Statement 2 is correct. PUNCH is expected to improve our understanding of space weather phenomena. The mission aims to provide scientists with new information that could lead to more accurate predictions about the arrival of space weather events on Earth and their impact on human technology in space.
