The Indian Space Research Organisation (ISRO) announced today that the magnetometer boom on the Aditya-L1 satellite has been successfully deployed. The deployment occurred on January 11, 2024, and the boom had been in a stowed condition for 132 days since the satellite’s launch.
Instead of using quotes, it can be stated that the boom carries two state-of-the-art, high-accuracy fluxgate magnetometer sensors that are designed to measure the low intensity interplanetary magnetic field in space. The sensors are deployed at distances of three and six metres from the spacecraft body.
During the stowed condition, the boom was securely held in position by two hold-downs, which transferred the launch loads to the spacecraft body. To execute the deployment, a thermal cutter-based release system was employed. The telemetry switches received data confirming the hold-down release, first motion, and locking of all hinges. The observed in-orbit deployment time was approximately nine seconds, falling well within the predicted range of 8 to 12 seconds.
ISRO reported that all telemetry indications for hinge locking and hold-down release were within nominal parameters, indicating the successful deployment of the magnetometer boom. This achievement is significant as it enables the Aditya-L1 satellite to effectively study and analyze the interplanetary magnetic field.
The deployment of the magnetometer boom marks an important milestone in the Aditya-L1 mission, which aims to observe the Sun from a stationary orbit around the Lagrange point L-1, providing crucial insights into its behavior and the effects of solar activity on space weather. ISRO’s success in deploying the boom demonstrates its technical expertise and capabilities in space exploration.
