高空大气监测和飞行中收集活微生物样品用的小型自给式系统

A Low-Profile, Self-Contained System for Atmospheric Monitoring and Mid-flight Collection of Viable Microbiological Samples at High Altitude

Caitlyn A. K. Singam

摘要:

相关文献已充分确定了细菌在大气中的流行,这表明空气中的细菌可以影响大气特征,包括云的发展。研究还表明,大气生物分布受到底层陆地生物群落的影响。要了解可能影响大气生物概况的各种因素的复杂相互作用,更不用说开展大气生物普查,就需要一个具有成本效益的实验系统,能够产生具有可靠数据的可重复结果。然而,正如美国航天局和日本宇宙航空研究开发机构等空间机构发射的有效载荷所表明的那样,这些有效载荷既复杂又成本高昂。本文讨论了设计和实施的生物导向的实验有效载荷的高空气球,是大多数学生运行的实验计划的手段。本专题介绍中重点介绍的有效载荷PHANTOM(高空微生物计数和跟踪探测器,其目标是在多个高度捕获空中微生物,以确定高层大气的生物组成特征)已经进行了多次成功的飞行试验,突出了航空航天与生物科学之间跨学科项目的可行性和实用性。

英文摘要:

The prevalence of bacteria in the atmosphere has been well established in relevant literature, suggesting that airborne bacteria can influence atmospheric characteristics including the development of clouds. Studies have also demonstrated that the atmospheric biological profile is influenced by the underlying terrestrial biomes. An understanding of the complex interplay of factors that can influence the atmospheric biological profile, not to mention developing a biological census of the atmosphere, requires a cost-effective experimental system capable of generating reproducible results with reliable data. However, as has been demonstrated by payloads launched by space agencies such as NASA and JAXA, these payloads are both complex and cost prohibitive. This paper discusses the design and implementation of a biologically oriented experimental payload for high-altitude ballooning that is within the means of most student-run experimental programs. The payload highlighted in this presentation, PHANTOM (Probe for High Altitude Numeration and Tracking of Microorganisms, which has the goal of capturing aerial microorganisms at multiple altitudes in order to characterize the biological composition of the upper atmosphere), has undergone a number of successful flight trials, and serves to highlight the feasibility and utility of interdisciplinary projects between aerospace and the biological sciences.
