The Air Force Research Laboratory (AFRL) Space Vehicles Directorate has developed the Demonstration and Sciences Experiment (DSX) to research the technologies needed to deploy space assets in the harsh MEO radiation environment. The DSX comprises three basic research experiments: 1) Wave Particle Interaction Experiment, 2) Space Weather Experiment, and 3) Space Environmental Effects Experiment.
Public reporting burden for this collection of information is estimated to average 1 hour per response, including the time for reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing this collection of information. Send comments regarding this burden estimate or any other aspect of this collection of information, including suggestions for reducing this burden to Department of Defense, Washington Headquarters Services, Directorate for Information (DoD) capability to operate spacecraft in the harsh radiation environment of medium-earth orbits (MEO). The ability to operate effectively in the MEO environment significantly increases the DoD's capability to field space systems that provide persistent global targeting-grade space surveillance, high-speed satellite-based communication, lower-cost GPS navigation, and protection from space weather on a responsive satellite platform. The three DSX physics-based research areas are: 1. Wave Particle Interaction Experiment (WPIx): Researching the physics of very-low-frequency (VLF) transmissions in the magnetosphere and characterizing the feasibility of natural and man-made VLF waves to reduce space radiation; 2. Space Weather Experiment (SWx): Characterizing and modeling the space radiation environment in MEO, an orbital regime attractive for future DoD and commercial missions; 3. Space Environmental Effects (SFx): Researching and characterizing the space weather effects on spacecraft electronics and materials. DSX uses a modular design that allows for launch either as a primary satellite on a conventional launcher, such as a Minotaur, or as a secondary payload on a larger rocket, such as the Evolved Expendable Launch Vehicle (EELV). Another key feature is the use of a dedicated payload computer, which unburdens the avionics of the need to conform to custom payload data interfaces, enabling the rapid procurement of a standard spacecraft bus. An overview of the DSX science experiments, payload design, spacecraft subsystems, and engineering approach will be described.
Abstract-The Air Force Research Laboratory (AFRL)Space Vehicles Directorate has developed a mission to research the technologies needed for large space structures, high-power generation, and protection of space assets within the high radiation environment of a medium earth orbit (MEO).The resulting Deployable Structures Experiment (DSX) will address a number of basic science experiments via a single MEO testbed platform. The DSX concept, with specific emphasis on scientific merit, relevance to the Air Force needs, and necessity for flight demonstration, was conceived and proposed for further development in mid-2003. The program then went through 8 months of proposal and review, maturing the overall design, scientific merit and payoff, and Air Force relevance. Ultimately, of the six proposed concepts, DSX was selected in January 2004 as the next AFRL/VS basic research flight experiment. During 2004 the DSX concept was refined, with specific focus on requirement derivation and allocation to hardware and software solutions. The DSX mission, matured in parallel, is the primary subject of this paper.The baseline DSX experiment should be launch ready by late 2009, with at least one year of on-orbit operations scheduled. DSX comprises five research experiments, that will pave the way for new Department of Defense (DoD) capabilities in space surveillance, microsats with large aperture and power, and protection of space assets from natural and enhanced radiation environments. The DSX experiments include research on:
