Deployable boom for Mars Orbiter Magnetometer onboard Tianwen-1
文献摘要：
A more than 3 m-long deployable boom is an essential component of the Mars Orbiter Magnetometer (MO-MAG) onboard the orbiter of Tianwen-1. The boom was developed to place fluxgate magnetometer (FGM) sensors away from the satellite to reduce the influence of the satellite magnetic field. It was designed as an articulated spring-driven deployable mechanism for single-shot deployment. Functionality, reliability and system constraints are fully con-sidered in the boom design. Mechanical analyses and proof tests show that the boom has sufficient safety margin to with-stand environmental conditions, even in the worst cases. After a long voyage from Earth to Mars, the boom was deployed successfully on May 25, 2021. A full deployment was performed in about 4.6 s, sending the two sensors to distances of 3.19 m and 2.29 m respectively, away from the orbiter. After deployment, the field from the orbiter decreased from 1250 nT to less than 6 nT at the sensor mounted at the tip of the boom. The MOMAG boom provides valuable engineering ex-perience for the development of deployable structures stowed for long periods in cold temperatures in space missions.
