AI总结：
本文研究AOSAT 1的姿态控制系统，分析其在部署后消除航天器自旋扰动的方法，并评估其在航天器内移重心质（碎陨石）影响下的稳定性，以提升对小行星物理模型的理解。
摘要：
小行星和小天体的探索能提供关于太阳系起源、地球起源以及生命基本构建块起源的宝贵见解。然而，小行星的低重力和未知表面条件给表面探索、操作和资源加工带来了巨大挑战，导致多个着陆器损失或任务缩短。根本研究需要更好地了解小天体的表面性质和物理模型。AOSAT 1是立方卫星离心实验室，以最高4 rpm的速度旋转，模拟亚1公里小行星的毫重力条件。该实验室将帮助降低小行星着陆和资源加工技术的开发和测试风险。实验室内有碎陨石，这些是小行星的残骸。实验室配备了摄像头和执行器，用于进行一系列科学实验，以更好地了解材料性质和小行星表面物理。这些结果将有助于改进小行星的物理模型。该立方卫星设计为低成本，包含3轴磁力矩器和一个单轴反应轮以产生自旋。在我们的工作中，我们首先分析了姿态控制系统在部署后如何消除航天器自旋扰动。进一步分析已进行，以分析姿态控制系统在航天器以离心模式旋转时内部移重心质（碎陨石）影响下的影响和稳定性。AOSAT 1将成为一系列低成本立方卫星离心机的首推，为未来的更大、更永久的在轨离心实验室铺平道路，用于行星科学、生命科学和制造实验。
英文摘要：
Exploration of asteroids and small-bodies can provide valuable insight into the origins of the solar system, into the origins of Earth and the origins of the building blocks of life. However, the low-gravity and unknown surface conditions of asteroids presents a daunting challenge for surface exploration, manipulation and for resource processing. This has resulted in the loss of several landers or shortened missions. Fundamental studies are required to obtain better readings of the material surface properties and physical models of these small bodies. The Asteroid Origins Satellite 1 (AOSAT 1) is a CubeSat centrifuge laboratory that spins at up to 4 rpm to simulate the milligravity conditions of sub 1 km asteroids. Such a laboratory will help to de-risk development and testing of landing and resource processing technology for asteroids. Inside the laboratory are crushed meteorites, the remains of asteroids. The laboratory is equipped with cameras and actuators to perform a series of science experiments to better understand material properties and asteroid surface physics. These results will help to improve our physics models of asteroids. The CubeSat has been designed to be low-cost and contains 3-axis magnetorquers and a single reaction-wheel to induce spin. In our work, we first analyze how the attitude control system will de-tumble the spacecraft after deployment. Further analysis has been conducted to analyze the impact and stability of the attitude control system to shifting mass (crushed meteorites) inside the spacecraft as its spinning in its centrifuge mode. AOSAT 1 will be the first in a series of low-cost CubeSat centrifuges that will be launched setting the stage for a larger, permanent, on-orbit centrifuge laboratory for experiments in planetary science, life sciences and manufacturing.
