What does the magnetometer onboard Aditya-L1 satellite primarily measure in space?
Show answer & explanation
Correct answer: B
Explanation
Solution: The correct answer is Interplanetary magnetic field strength and direction.
Explanation:
☛ The Magnetometer (MAG) payload onboard the Aditya-L1 mission is designed to measure the magnitude and nature of the interplanetary magnetic field in space.
☛ It is deployed at the Sun-Earth Lagrange Point 1 (L1) to observe low-intensity magnetic fields associated with solar events like Coronal Mass Ejections (CMEs).
☛ To prevent magnetic interference generated by the spacecraft itself, the sensors of MAG are mounted on a 6-meter-long deployable boom.
☛ This payload was developed by the Laboratory for Electro-Optics Systems (LEOS), Bengaluru, an ISRO unit.
Extra Exam-Relevant Facts:
☛ Aditya-L1 Mission: India's first dedicated space observatory to study the Sun, launched on 2 September 2023 aboard PSLV-C57.
☛ Total Payloads: Aditya-L1 carries 7 payloads, consisting of 4 remote sensing payloads and 3 in-situ observation payloads.
☛ In-situ Payloads: These include MAG (Magnetometer), ASPEX (Aditya Solar wind Particle Experiment), and PAPA (Plasma Analyser Package for Aditya).
☛ Remote Sensing Payloads: These include VELC, SUIT, SoLEXS, and HEL1OS.
