Abstract:The current available in situ data on the physical characteristics of the 90-130 km environment depends on sounding rocket and maneuverable satellite systems for its collection. Such data are, of necessity, sporadic in both time and space. The development of tethered systems in Earth orbit will allow global, long-term observations of this environment for the first time. In addition, tethered systems will allow spacial gradiometry at altitudes from 130-400 km without the extensive celestial mechanics required t… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
