Mission
DANDE’s mission statement is to explore the spatial and temporal variability of the neutral thermosphere at altitudes between 200 and 350 km (revised to 325-500 km due to a new orbit since the beginning of the project), and investigate how wind and density variability translate to drag forces on satellites. The density of the atmosphere varies greatly due to space weather and other unknown processes. The International Space Station once dropped in height by tens of kilometers in a span of a few days and by understanding drag forces and composition of the atmosphere we can provide better data about this phenomenon.
Mission Objectives
1. Establish and understand the relationship between total mass density, composition, and winds as functions of latitude, level of magnetic activity, and horizontal scale.
2. Establish the relative contributions of density and winds to satellite drag as a function of latitude, level of magnetic activity, and horizontal scale.
3. Demonstrate key technologies for performing in-situ measurements of the orbital drag environment at low cost.
4. Improve understanding of the variation in coefficient of drag in the 325-500 km altitude region.

“We never can tell how our lives may work to the account of the general good, and we are not wise enough to know if we have fulfilled our mission or not.”
—Ellen Henrietta Swallow Richards (1842–1911)
“Man is eminently a storyteller. His search for a purpose, a cause, an ideal, a mission and the like is largely a search for a plot and a pattern in the development of his life story—a story that is basically without meaning or pattern.”
—Eric Hoffer (1902–1983)
