The broader impact/commercial potential of this Small Business Innovation Research (SBIR) project enables an entirely new class of space habitat that will enable humans to live and work in space without endangering their health. In the near future, improvements in launch capability will radically increase the number of people traveling to space to take advantage of what can only be done in microgravity. These include researchers studying the next lifesaving medicine, workers manufacturing high-purity semiconductors for the next generation of computers, and tourists wanting to experience the freedom of space and the sight of Earth. These individuals share a common need: easy access to microgravity to fulfill their purpose of being in space while simultaneously not enduring significant health impacts from microgravity exposure; thus, both microgravity and artificial gravity need to be accessible in the same space habitat. Development of platforms such as these would help enable an acceleration of in-space R&D, along with supporting higher throughput of in-space experimentation and R&D. The solution is very large, expandable non-rotating space habitats, with an internal rotating centrifuge large enough for astronauts to live and work in when not needing microgravity. These centrifuges need an advanced stabilization system because as astronauts move around the centrifuge, the center-of-gravity shifts, which due to the rotation would induce a wobble. This SBIR Phase I project proposes to solve the stabilization problem while avoiding flaws of previously proposed approaches and is also applicable to traditional rotating space stations. The objective of this research is to build representative lab-scale prototypes of the stabilization system and develop a control system model to prove the efficacy of this stabilization system when at full scale. This includes capturing the responsiveness required for the system to stabilize human motion, such as walking, proving redundancy is present, and characterizing the overall impact centrifuge mass distribution has on the stabilization control system. Further prototypes will demonstrate its ability to package within an expandable habitat module, while additional analysis will quantify the cost benefits of designing a habitat incorporating a large internal centrifuge and stabilization system.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这项小型企业创新研究（SBIR）项目的更广泛的影响/商业潜力使一个全新的太空栖息地将使人类能够在太空中生活和工作而不会危害其健康。 在不久的将来，发射能力的提高将从根本上增加前往太空的人数，以利用只能在微重力方面做的事情。 其中包括研究下一种救生医学的研究人员，为下一代计算机制造高纯度半导体的工人，以及希望体验空间自由和地球视线的游客。 这些人有一个共同的需求：轻松获得微重力以实现其在太空中的目的，同时不承受微重力暴露的重大健康影响；因此，在同一空间栖息地中，微重力和人工重力都需要可进入。 这样的平台的开发将有助于加速空间研发，并支持更高的空间实验和研发。 该解决方案非常大，可扩展的非旋转空间栖息地，内部旋转离心机足够大，可以在不需要微重力的情况下生活和工作。 这些离心机需要一个先进的稳定系统，因为随着宇航员在离心机周围移动时，重心的转移会导致旋转引起摇摆。该SBIR I期项目提议解决稳定问题，同时避免了先前提出的方法的缺陷，并且也适用于传统的旋转空间站。 这项研究的目的是构建稳定系统的代表性实验室规模原型，并开发控制系统模型，以证明该稳定系统在完整规模时的功效。这包括捕获系统稳定人类运动所需的响应能力，例如行走，证明冗余，并表征整体影响离心机质量分布对稳定控制系统的质量分布。 进一步的原型将证明其在可扩展的栖息地模块中包装的能力，而其他分析将量化设计栖息地的成本优势，该栖息地纳入了庞大的内部离心机和稳定系统。该奖项反映了NSF的法定任务，并被认为是通过使用该基金会的智力和更广泛影响的评估来审查CRITERIA的评估来通过评估来获得支持的。
