DANDE

Drag and Atmospheric Neutral Density Explorer
DANDE

Measuring drag and neutral particles in the lower atmosphere between 325-400 kilometers, DANDE will be measuring real time density, quantifying variations in altitude and over time, as well as providing in-situ model calibration data. The satellite is a low-cost density, wind, and composition measuring instruments that will provide data for the calibration and validation of operational models and improve our understanding of the thermosphere. Weighing approximately 84 pounds, DANDE is classified as a nano-satellite that is about 18 inches in diameter.
The Colorado Space Grant Consortium (COSGC) has housed the project for approximately 7 years, in which about 150 students have been a part of the project through initial concept and design, to the current team of mission operators. There are two instruments on board which allow DANDE to make in-situ measurements rather than being passive or only carrying accelerometers. The subsystem ACC (Accelerometers) contains 6 accelerometer heads arranged in a circle which were built in-house. The NMS subsystem (Neutral Mass Spectrometer) also known as Wind and Temperature Spectrometer will survey the variety and quantity of numerous neutral particles in the Thermosphere. This data will be particularly interesting during periods of high solar activity do to atmospheric effects seen at these times in the polar regions of Earth.
