First amateur satellite with onboard propulsion. The booster bumped Oscar 10 shortly after separation which damaged one or more of its antennas and also caused other internal injuries because the second and subsequent kick motor firings never happended. This left the spacecraft in a lower inclination elliptical orbit. This meant that the bird didn't have the intended operational coverage nor enough solar panel illumination to sustain full operations.
