The Polar BEAR spacecraft was developed to measure auroral and ionospheric parameters and their effects on RF wave propagation. It provides coverage of the auroral oval in an area different from that covered from previous spacecraft, and the data gathered will complement the research being carried out by earlier programs. This article provides a technical description of the spacecraft and its initial in-orbit performance.
