Welcome to the Boston University Space Physics Acquisition Center
BUSPACE provides data acquired from the missions, experiments, and instruments which involved or involve the Boston University Center for Space Physics faculty and students. This node of the Space Physics Data System exists to provide access to data dealing with space physics phenomena found in the Earth extended upper atmosphere known as the ionosphere and magnetosphere and acquired by a variety of rockets, spacecrafts, and ground-based equipment.
The Energetic Particle Group: EPG
The Energetic Particle Group consists of individuals studying the dynamics of energetic particles within planetary magnetospheres. An ensemble of undergraduates, graduate students, and faculty from the Center for Space Physics comprise the EPG. Professor Theodore A. Fritz is the primary investigator of the EPG. Professor Fritz joined the Boston University Center for Space Physics faculty in January 1992. His research interests include the study of charged particles and their compositions in the magnetospheres of the Earth and Jupiter. He has participated in a variety of projects such as the International Sun-Earth Explorer 1&2 (ISEE 1&2), the NASA International Solar Terrestrial Physics (ISTP) Polar mission, and the joint ESA/NASA Cluster mission.
The Loss Cone Imager (LCI) Experiment
Professor Fritz is the Principal Investigator of the Loss Cone Imager (LCI) experiment presently being developed for the U.S. Air Force Demonstration and Science (DSX) satellite project. The Mission of DSX is to determine the efficiency of broadcasting electromagnetic radiation in the VLF frequency range within the Earth's magnetosphere in order to migrate energetic magnetospherically trapped electrons into the atmospheric loss cone. The loss cone represents the range of particle pitch angles corresponding to particles that have their mirror points at or below 100 km. The LCI instrument will measure the flux of electrons in this loss cone from which it gets its name.
The Boston University Student-satellite for Applications and Training: BUSAT
The EPG is participating in the U.S. Air Force Nanosat 5 competiion with an entry called BUSAT, the Boston University Student-satellite for Applications and Training. BUSAT is a comprehensive, integrated nano-satellite project involving graduate students, undergraduate students, and faculty in the engineering and science departments of Boston University. The purpose of the planned satellite is to perform measurements of the precipitating energetic electron fluxes from low Earth orbit over the high latitude auroral zones and to simultaneously image the auroral emissions caused by these electrons. The Boston University Center for Space Physics is a leading space weather research institution and is involved in the study of auroral emissions with ground-based radars, optical instruments, and magnetometers. Present efforts to characterize the electron energy spectrum from the information obtained by these ground based instruments is a main thrust of this research but these efforts are limited by lack of the measured electron precipitating fluxes directly. The planned satellite will permit this loop to be effectively closed. The satellite structure and bus rely on the cube-sat concept developed by prior nanosat funded efforts at a number of universities and will rely specifically on the experience gained in such a program at Taylor University (Uplands, IN). The communication (command and telemetry) subsystem will be procured via a subcontract directly from TU. Many of the TU designs will be utilized for BUSAT but will be developed and fabricated by student teams at BU. The needed auroral imager and imaging electron spectrometer (IES) will also be fabricated by student teams relying on the in-depth experience with such instruments by BU faculty. Presently more than 70 engineering and science undergraduates are developing BUSAT.
