地球电离层主要由太阳对高层大气中原子的电离作用产生。这一等离子体环境高度动态，表现出强烈的时空变化，并对电力系统、导航、卫星及地面通信产生显著影响。特拉华大学电离层探测器（UDIP）作为特拉华大学学生关于电离层本身及空间技术开发的动手学习体验而开发。学生（主要是本科生）主导了实验的各个方面，包括任务规划、电子开发、机械开发、软件开发及科学数据分析。本研究旨在为读者提供如何将空间及近空间飞行任务的开发成功融入本科物理课程的指南。实验的第四版（UDIP-4）搭载2024年RockSat-C探空火箭飞行，该火箭从NASA沃洛普斯飞行设施发射，随行的还有来自美国各地的学生实验。飞行期间，UDIP-4的朗缪尔探针成功测量了电离层密度剖面——电子密度随高度的变化——直至114公里的远地点。尽管测得的密度剖面总体与理论模型的预测吻合良好，UDIP-4在约110公里高度识别出一个增强电子密度的薄层，这与偶发E层一致。
英文摘要
Earth's ionosphere is primarily generated by the Sun's ionization of atoms in the upper atmosphere. This plasma environment is highly dynamic, exhibits strong spatial and temporal, variations and significantly impacts power systems, navigation, and satellite and ground communications. The University of Delaware Ionospheric Probe (UDIP) was developed as a hands-on learning experience for University of Delaware students on the ionosphere itself and on the development of space technology. Students (mostly undergraduates) have led all aspects of the experiment including mission planning, electronics development, mechanical development, software development, and scientific data analysis. The present study is intended as a guide to readers on how the development of space and near-space flight missions can be successfully incorporated into an undergraduate physics curriculum. The fourth version of the experiment (UDIP-4) flew along with student experiments from across the USA on the 2024 RockSat-C sounding rocket, which was launched from NASA Wallops Flight Facility. During the flight, UDIP-4's Langmuir probe successfully measured the ionosphere's density profile -- electron density as a function of altitude -- up to an apogee of 114 km. Though the measured density profile agrees well overall with the predictions of theoretical models, UDIP-4 identified a thin layer of enhanced electron density at an altitude of approximately 110 km that is consistent with a sporadic E layer.
