NASA/TM-108543, Johnson, L. and Herrmann, M., Tether-Based Investigation of the Ionosphere and Lower Thermosphere Concept Definition Study Report, Program Development Directorate NASA Marshall Space Flight Center, AL 35812, September 1997, pp. 28, Format(s): PDF 365k |
Understanding the plasma and atmosphere around the Earth in the lower altitude regions of the mesosphere, lower thermosphere, and ionosphere is important in the global electric system. An upper atmosphere tether has been proposed to NASA that would collect much-needed data to further our knowledge of the regions. The mission is proposed as a shuttle experiment that would lower a tethered probe into certain regions of Earth's atmosphere, collecting data over a 6-day period. This report is a summary of the results of a concept definition study to design engineering system that will achieve the scientific objectives of this mission
