This will be accomplished through the use of a constellation of small payloads that separate relative to each other throughout a sounding rocket flight. The multiple baseline observations of the electric and magnetic fields will be used to observe variability of both the E-field and the Poynting flux. These observations will be placed in the context of available data, including winds, large scale E-fields, and proxy conductivity (airglow images) observations. In this way we will address the main scientific objective of this mission which is: What are the contributions of small spatial scale and rapid temporal scale fluctuations of electric fields relative to the larger-scale electrodynamic processes? The high altitude rocket will be launched along the magnetic field line and carry six sub-payloads to be ejected from the main payload at high velocity. The sub-payloads will be deployed both along the flight path and perpendicular to the flight path so that both spatial features and temporal-spatial ambiguities can be explored. The low-mass sub-payloads that, for a fixed ejection impulse will achieve at least a 50 km separation by the end of the flight are key to the observational success. Each sub-payload will carry a crossed pair of double-probe sensors to measure in-situ electric fields, a three axis magnetometer, a Langmuir probe and a GPS receiver. In this poster we review the ASSP science and mission concepts.</p>\r\n<p>\r\n\t </p>\r\n<p>\r\n\t </p>", "distribution": [{"@type": "dcat:Distribution", "downloadURL": "http://techport.nasa.gov/xml-api/10767", "format": "XML", "mediaType": "application/xml"}], "identifier": "TECHPORT_10767", "issued": "2011-03-01", "keyword": ["active", "project", "wallops-flight-facility"], "landingPage": "http://techport.nasa.gov/view/10767", "modified": "2025-03-31", "programCode": ["026:000"], "publisher": {"@type": "org:Organization", "name": "Science Mission Directorate"}, "references": ["http://techport.nasa.gov/doc/home/TechPort_Advanced_Search.pdf", "http://techport.nasa.gov/fetchFile?objectId=3447", "http://techport.nasa.gov/fetchFile?objectId=3448", "http://techport.nasa.gov/fetchFile?objectId=3456", "http://techport.nasa.gov/fetchFile?objectId=6560", "http://techport.nasa.gov/fetchFile?objectId=6561", "http://techport.nasa.gov/fetchFile?objectId=6584", "http://techport.nasa.gov/home"], "temporal": "2011-03-01T00:00:00Z/2014-02-01T00:00:00Z", "title": "Auroral Spatial Structures Probe Project"}
