1Both Pioneer-5 and Explorer-6 were "paddlewheel" satellites. It is believed that Explorer-6 contained two short antennas on its "top", whereas Pioneer-5 contained only a single short antenna. When there are no antennas on top, the distinction is unclear, but of the two, Pioneer-5 is assumed. Other non-planetary Pioneers appear on the Pioneer-series page.
2Additional Vanguard-2 items appear on the Vanguard-series page.
