The MightySat II.1 program, an Air Force Research Laboratory (AFRL) endeavor, was conceived to provide a small, economical space demonstration platform enabling the rapid transition of some of the nation's most advanced technologies in imaging, communications, and spacecraft bus components from the laboratory to space flight operations. MightySat II.1 carried ten experiments, including the Fourier Transform Hyperspectral Imager (FTHSI), the only DoD space-based hyperspectral imager to use the Fourier transform technique to discern spectrally unique objects. The other demonstration technologies included the shape memory alloy thermal tailoring experiment, multifunctional composite bus structure, solar array concentrator, solar array flexible interconnect, Quad-C40 processor, NRL mini SGLS transponder, two PICO Sats, orthogrid substrate, and starfire optical reflectors.
MightySat II.1 successfully completed its one year mission and the demonstration of all experiments. The spacecraft continued to function until its natural reentry into the atmosphere in November 2002 at 233% of its design lifetime.
