Q. With reference to the Aditya-L1 mission, consider the following statements:
1.Halo orbit used by the Aditya-L1 mission is an elliptical orbit around the Sun.
2.Aditya-L1 is a solar observatory spacecraft sent by ISRO.
3.The halo orbit of Aditya-L1 is chosen because it allows the spacecraft to observe the entire surface of the Sun.
How many of the statements given above are correct?
Answer: A
Notes:
Explanation –
Statements 1 and 3 are incorrect. The halo orbit used by the Aditya-L1 mission is s a periodic, three-dimensional orbit around the Lagrange point 1 (L1) of the Sun-Earth system. This orbit is roughly perpendicular to the line joining the Earth and the Sun. The halo orbit around the L1 point allows Aditya-L1 to continuously observe the Sun without any occultation or eclipse, providing an unobstructed view of solar activities. However, it does not allow observation of the entire surface of the Sun, but rather continuous observation of the Sun.
Statement 2 is correct. Aditya-L1 is a solar observatory spacecraft sent by the Indian Space Research Organisation (ISRO) to study the Sun.
