项目摘要
This project is for a 3U CubeSat mission named EXOCUBE to measure the densities of all significant neutral and ionized species in the upper atmosphere on a global scale. The project will provide the first in-situ global neutral density data in more than 25 years, including the first direct measurements of Hydrogen densities using the mass spectrometer technique. An important science objective for EXOCUBE is to provide observational constraints for physical models of the upper atmosphere. Additionally, the measurements will be used to test and validate newly developed experimental techniques to obtain neutral and ionized composition and densities from radar and optical observations. The EXOCUBE measurements will also be used for several immediate science investigations. Specific science questions to be addressed include: 1) the inter-hemispheric transport of Hydrogen and protons in the quiescent and storm-time exosphere, and 2) characterization of neutral atmospheric drivers in response to magnetic storms. Data for each of four neutral and ion species (O, He, H, N2, O+, He+, H+, and NO+) are gathered by a set of two Static Energy Angle Analyzers, one for Neutrals (NSEAA) and one for Ions (ISEAA), respectively. The instrument is a new design that has been developed recently through a collaboration between NASA and the Naval Research Laboratory. A third instrument, a Faraday cup, is included for calibration, reducing ion density uncertainties to approximately plus or minus 3%. The satellite will collect data in two modes. In 'patrol mode' the measurements will be made approximately every degree of longitude and in 'coordinated experimental mode' the measurements will be made every tenth of a longitude degree in conjunction with ground based radar and optical measurements. The satellite is to be launched into low Earth orbit with an inclination of greater than or equal to 45 degrees, passing over three current radar sites, and at least six optical Aeronomy sites. The EXOCUBE project is a collaboration between Scientific Solutions Inc. (SSI), California Polytechnic State University (Cal Poly), and The University of Wisconsin (UW). Also partnering in the effort are NASA Goddard Space Flight Center, and SRI International. In addition, the project coordinates with existing NSF radar facilities and optical sites for targeted experiments during the satellite lifetime. The EXOCUBE dataset has broad utility, leading to long-awaited improvements in a wide range of physical and semi-empirical composition models for the upper atmosphere and to verification of radar and optical measurement techniques providing composition data. As such, the project will provide the foundation for a very large and diverse set of further aeronomy and space weather science investigations. Particularly, reliable knowledge of exospheric Hydrogen distribution is a crucial requirement for realistically modeling Total Electron Content, which is currently a very high priority space weather objective. Educational impacts of the project are extraordinary. The satellite bus and operating systems are designed and built by 20-40 students in the laboratories at Cal Poly, and payload integration is also performed by students at Cal Poly. Students at the University of Wisconsin are involved with instrument calibration and testing and with initial assessment of data integrity. Data formatting and archiving are also student led.
这个项目是一个名为EXOCUBE的3U立方体卫星任务,用于测量全球范围内高层大气中所有重要的中性和电离物质的密度。该项目将提供超过25年来第一个原位全球中性密度数据,包括使用质谱仪技术首次直接测量氢密度。exoccube的一个重要科学目标是为高层大气的物理模型提供观测约束。此外,这些测量将用于测试和验证新开发的实验技术,以从雷达和光学观测中获得中性和电离成分和密度。exoccube的测量结果还将用于几项直接的科学研究。需要解决的具体科学问题包括:1)静止和风暴时外逸层中氢和质子的半球间运输,以及2)响应磁暴的中性大气驱动因素的表征。四种中性和离子(O, He, H, N2, O+, He+, H+和NO+)的数据分别由一组两台静态能角分析仪收集,一台用于中性(NSEAA),一台用于离子(ISEAA)。该仪器是最近由美国宇航局和海军研究实验室合作开发的一种新设计。第三个仪器,法拉第杯,包括校准,减少离子密度不确定度约为正负3%。卫星将以两种模式收集数据。在“巡逻模式”下,测量将在大约每经度上进行,而在“协调实验模式”下,测量将与地面雷达和光学测量相结合,每经度的十分之一进行一次。该卫星将以大于或等于45度的倾角发射到近地轨道,经过三个现有雷达站点和至少六个光学航空站点。EXOCUBE项目是科学解决方案公司(SSI)、加州州立理工大学(Cal Poly)和威斯康星大学(UW)之间的合作项目。美国宇航局戈达德太空飞行中心和SRI国际公司也参与了这项工作。此外,该项目与现有的NSF雷达设施和光学站点进行协调,以便在卫星寿命期间进行有针对性的实验。EXOCUBE数据集具有广泛的实用性,可以对高层大气的各种物理和半经验成分模型进行期待已久的改进,并验证提供成分数据的雷达和光学测量技术。因此,该项目将为进一步开展大量多样的航空和空间气象科学研究提供基础。特别是,可靠的外逸层氢分布知识是实际模拟总电子含量的关键要求,这是目前非常优先考虑的空间天气目标。该项目对教育的影响是非凡的。卫星总线和操作系统由20-40名学生在加州理工学院的实验室设计和建造,有效载荷集成也由加州理工学院的学生进行。威斯康星大学的学生参与了仪器校准和测试以及数据完整性的初步评估。数据格式化和归档也是由学生主导的。
