CubeSats are miniaturized, low-weight, low-cost satellites. Due to these properties, constellations of 10s-100s of CubeSats with specialized instruments for studying the space environment provide a new exciting opportunity to understand and predict space weather. The Space Weather Atmospheric Reconfigurable Multiscale Experiment (SWARM-EX) project provides an important step in the advancement of designing and building CubeSat constellations for space weather. SWARM-EX will consist of three identical CubeSats with novel technologies for radio communications between satellites, onboard propulsion, advanced data downlinks, and autonomous operations within the constellation. Each satellite will measure ionized and neutral gases in the Earth's upper atmosphere, studying structures seen near the equator. The SWARM-EX mission uniquely fosters opportunities for STEM education and enables a platform for public outreach. SWARM-EX will establish the first Intercollegiate CubeSat Mentoring Program - partnering institutions that have established CubeSat programs with new programs to create long-term, project-based learning environments across the nation. Teaching, training, and learning will also be advanced through the inclusion of multiple graduate students, and undergraduate students from the six geographically distributed university programs involved in SWARM-EX. This project resulted from the Ideas Lab: Cross-cutting Initiative in CubeSat Innovations, an interdisciplinary program supported by Geosciences, Engineering, and Computer and Information Science and Engineering Directorates.SWARM-EX is a bold step towards addressing outstanding aeronomy questions achieved through a global constellation of CubeSat swarms making in-situ ionospheric and thermospheric measurements between 300 and 600 km altitude. The CubeSats in each swarm will range in separation from 1 to 1000 km and this separation will be controlled by a combination of differential drag and onboard propulsion. A pathfinder mission, supported by this project will use 3 identical CubeSats to demonstrate the SWARM-EX key technologies and address scientific questions related to the evolution of the equatorial ionization anomaly (EIA) and equatorial thermospheric anomaly (ETA). The specific aeronomy questions are 1) How persistent and correlated are the plasma density and neutral oxygen in EIA and ETA features?; 2) Over what timescales, less than 90 minutes, do we observe changes in EIA/ETA properties due to non-migrating tides and geomagnetic activity? These CubeSats will demonstrate novel technology including RF cross-links, propulsion, CDMA X-band data downlinks and on-board autonomy. Additionally, each CubeSat will include an atomic oxygen sensor and Langmuir Probe thus making the measurements required to answer the proposed science questions.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.

CubeSat是小型化、低重量、低成本的卫星。 由于这些特性，具有专门研究空间环境的仪器的10 - 100个立方体卫星星座为了解和预测空间天气提供了一个令人兴奋的新机会。 空间气象大气层可重构多尺度实验（SWARM-EX）项目是推动空间气象立方体卫星星座设计和建造的重要一步。 SWARM-EX将由三颗相同的立方体卫星组成，这些卫星具有卫星之间无线电通信、机载推进、先进数据下行链路和星座内自主操作的新技术。 每颗卫星将测量地球高层大气中的电离和中性气体，研究赤道附近的结构。 SWARM-EX的使命独特地促进了STEM教育的机会，并为公共宣传提供了一个平台。 SWARM-EX将建立第一个校际CubeSat指导计划-与已经建立CubeSat计划的机构合作，在全国范围内创建长期的基于项目的学习环境。 教学，培训和学习也将通过纳入多个研究生和本科生从六个地理分布的大学计划参与SWARM-EX推进。 该项目源于想法实验室：CubeSat创新的跨领域举措，这是一个由地球科学、工程和计算机与信息科学与工程理事会支持的跨学科项目。SWARM-EX是通过全球CubeSat群星座在300至600公里高度之间进行电离层和热层原位测量，朝着解决悬而未决的高层大气学问题迈出的大胆一步。 每个群中的立方体卫星的间隔将从1到1000公里不等，这种间隔将由差分阻力和机载推进力的组合控制。由该项目支持的一个探路者使命将使用3个相同的立方体卫星来演示SWARM-EX的关键技术，并解决与赤道电离异常（EIA）和赤道热层异常（ETA）演变有关的科学问题。 具体的高层大气力学问题是：（1）EIA和ETA特征中等离子体密度和中性氧的持续性和相关性如何？2)在不到90分钟的时间尺度内，我们观察到由于非迁移潮汐和地磁活动而导致的EIA/ETA属性的变化？ 这些立方体卫星将展示新技术，包括射频交叉链路、推进、CDMA X波段数据下行链路和机载自主性。 此外，每个立方体卫星将包括一个原子氧传感器和朗缪尔探测器，从而使所需的测量，以回答拟议的科学问题。这个奖项反映了NSF的法定使命，并已被认为是值得的支持，通过评估使用基金会的智力价值和更广泛的影响审查标准。
