Scientific paper

There is a strong need to understand how our near-Earth space environment behaves. This is due to the facts that we rely on assets in low Earth orbit, that our communication and navigation are dependent upon the conditions there, and that this transition region from neutral to ionized environment is a natural laboratory for studying plasma physics. One of the major hurdles of studying the ionosphere/thermosphere system is that the main drivers, such as the aurora, can take place at very small scales but occur over vast areas. In addition, waves that transport the energy and momentum have no boundaries in latitude or longitude, so they can traverse the entire globe. This makes it extremely difficult to understand the system-level response to those drivers with a single, or even a small number of satellites. A way to overcome this is to launch many Micro- or Nano-satellites that are outfitted with instruments that are capable of measuring a few key quantities in the IT system. The Armada mission is designed in this way - 48 CubeSats with an instrument that is capable of measuring the thermospheric and ionospheric composition, temperature and winds. In this presentation, we will fully describe the individual satellites, how they will be deployed, and the science that can be accomplished by such a mission.
