There were six experiments on the FASTSAT bus, including:
NanoSail-D2: NanoSail was designed to demonstrate deployment of a compact solar sail boom system. Although NanoSail originally failed to eject from the FASTSAT as planned, two weeks after launch, on January 17, 2011, it ejected, and successfully deployed its sail three days later.
Miniature Imager for Neutral Ionospheric Atoms and Magnetospheric Electrons : The Miniature Imager for Neutral Ionospheric Atoms and Magnetospheric Electrons or MINI-ME, a low energy neutral atom imager, was designed to detect neutral atoms formed in the plasma population around Earth to improve global space weather prediction. Low energy neutral atom imaging is a technique first pioneered at Goddard Space Flight Center, that allows scientists to observe remotely various trapped charged particle populations around Earth that would normally only be able to be observed in-situ – or exactly where an instrument is located. MINI-ME represents an improvement on the same kind of instrument, LENA, that flew on the IMAGE 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.
Plasma Impedance Spectrum Analyzer : PISA was designed to test a new approach to measuring the electron number density 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, 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 will demonstrate 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 was designed to provide the first global-scale measurements of temperature in the top-most region of Earth's atmosphere or "thermosphere". The TTI is used to observe thermospheric temperature profiles in the 90–260 km 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.
