On January 11, 2024, the Aditya-L1 spacecraft achieved a groundbreaking milestone by deploying its 6-meter-long magnetometer boom in space at Lagrange Point-1. This achievement, 132 days post-launch, is pivotal for the mission's goal of studying the Sun's chromosphere, corona, and interplanetary magnetic field, contributing to advanced solar physics research.

The Aditya-L1 spacecraft, a project by ISRO, celebrated a major triumph on January 11, 2024, successfully deploying its 6-meter-long magnetometer boom in space at Lagrange Point-1. This significant accomplishment occurred 132 days post-launch, while the spacecraft was positioned in a halo orbit at the Lagrange point L-1.

The magnetometer boom holds paramount importance in the Aditya-L1 mission, which is dedicated to studying various aspects of the Sun, including its chromosphere, corona, and interplanetary magnetic field. Equipped with two advanced fluxgate magnetometer sensors, strategically placed at distances of 3 and 6 meters from the spacecraft's main body, the boom aims to measure low-intensity magnetic fields in space.

To ensure precision in measurements, the dual sensors help minimize interference from the spacecraft's magnetic field, providing more accurate estimations. The boom's innovative design, constructed from carbon fiber-reinforced polymer, features an articulated mechanism with five segments connected by spring-driven hinge mechanisms. This design enables the boom to fold and deploy accordion-style, controlled by a patented Kevlar closed control loop mechanism.

During the deployment operation, the boom, held securely during the launch phase by two hold-downs, initiated its unfolding process through a thermal cutter-based release system upon command. Telemetry data confirmed the seamless release of the hold-downs, the initial motion of the boom, and the successful locking of all hinges. The deployment time, recorded at approximately 9 seconds, fell within the predicted range of 8 to 12 seconds.

This flawless deployment operation marks a significant step forward for the Aditya-L1 mission, allowing scientists to gather precise measurements of the interplanetary magnetic field. This, in turn, contributes to a deeper understanding of solar phenomena and their impact on space weather, signifying a groundbreaking achievement in the realm of solar physics research.
