Abstract

In studying space physics, planetary science, and space weather, space-based in situ measurements of the magnetic field are fundamental to understanding underlying physical processes, as well as providing context for other observations. Whilst in many cases instrument design is not severely constrained by the available resource envelope, there are many applications, particularly when using new generations of spacecraft platforms such as CubeSats, that require very low resource sensors. In this context we review the design, development, construction, and flight of the highly miniaturised MAGIC (MAGnetometer from Imperial College) instrument on the RadCube Technology Demonstration CubeSat. MAGIC consists of a boom-mounted (outboard) Anisotropic Magneto-Resistive (AMR) vector sensor connected by harness to a single electronics card inside RadCube. A second inboard AMR vector sensor is mounted on the electronics card. RadCube launched on 17 August 2021 to a sun-synchronous low-Earth polar orbit, with the main mission lasting until April 2022. Routine operations were subsequently extended to the end of 2022, with further special operations in 2023 and 2024 before re-entry on 20 August 2024. Here we review RadCube observations made over more than two years in orbit. Key results from MAGIC on RadCube include meeting ESA space weather magnetic field measurement requirements with both the outboard and inboard sensor, as well as detection of field aligned current signatures at high latitude.

RadCube立方卫星上MAGIC磁阻磁强计的飞行性能。
在研究空间物理学、行星科学和空间天气时,基于空间的磁场原位测量是理解潜在物理过程的基础,也是为其他观测提供背景的基础。虽然在许多情况下,仪器设计不受可用资源包线的严重限制,但有许多应用,特别是在使用新一代航天器平台(如立方体卫星)时,需要非常低的资源传感器。在此背景下,我们回顾了RadCube技术演示立方体卫星上高度小型化的MAGIC(帝国理工学院磁强计)仪器的设计、开发、建造和飞行。MAGIC由一个吊杆安装的各向异性磁阻(AMR)矢量传感器组成,通过线束连接到RadCube内部的单个电子卡上。第二个板载AMR矢量传感器安装在电子卡上。RadCube于2021年8月17日发射到太阳同步低地球极轨道,主要任务将持续到2022年4月。常规行动随后延长至2022年底,在2024年8月20日重新进入之前,在2023年和2024年进行进一步的特别行动。在这里,我们回顾RadCube在轨道上进行的两年多的观测。RadCube上的MAGIC的主要结果包括满足欧空局空间天气磁场测量要求的内外传感器,以及高纬度地区场对准电流特征的检测。

期刊介绍: Space Science Reviews (SSRv) stands as an international journal dedicated to scientific space research, offering a contemporary synthesis across various branches of space exploration. Emphasizing scientific outcomes and instruments, SSRv spans astrophysics, physics of planetary systems, solar physics, and the physics of magnetospheres & interplanetary matter. Beyond Topical Collections and invited Review Articles, Space Science Reviews welcomes unsolicited Review Articles and Special Communications. The latter encompass papers related to a prior topical volume/collection, report-type papers, or timely contributions addressing a robust combination of space science and technology. These papers succinctly summarize both the science and technology aspects of instruments or missions in a single publication.
