mission about ten years ago. Measurements made by instruments like MINI-ME will enable more accurate prediction of space weather and a better understanding of plasma physics processes near Earth.Three FASTSAT Instruments Pass Tests
* Plasma Impedance Spectrum Analyzer (PISA): PISA was designed to test a new approach to measuring the electron number density (number of electrons per cubic centimeter) in the ionosphere. PISA uses a wide-band, rapid-sampling "impedance probe" technique, which stimulates the plasma surrounding FASTSAT with a short antenna. This technique identifies natural resonance frequencies in the plasma (such as the "plasma frequency"), which are directly related to the electron number density, magnetic field strength, and electron temperature. This approach is similar to striking a bell and using the tones created to deduce how the bell is constructed. PISA demonstrated the accuracy of this technique, and provide measurements of small-scale structure in the plasma. These small scale structures are important because they tend to scatter radio waves transmitted by satellites at high altitudes such as GPS or communication satellites. A better understanding of when and where these structures form, and their extent, will help to improve forecasts of communication and navigation outages. PISA was built at Goddard Space Flight Center. * Thermospheric Temperature Imager (TTI): TTI was designed to provide the first global-scale measurements of temperature in the top-most region of

". The TTI is used to observe thermospheric temperature profiles in the region. The temperature profile regulates the height of the atmosphere and controls the atmospheric density at orbital altitudes. Large increases in atmospheric density increase aerodynamic drag experienced by low altitude, Earth orbiting spacecraft leading to premature de-orbiting of the spacecraft.
