American test vehicle. The rocket's first three stages would take the upper stage package to a 260 km apogee. The upper stage package was mounted upside-down in relation to the other stages. When it had reached the peak, the three upper stages fired in sequence, ramming the payload, a 13 cm sphere, into the atmosphere at orbital re-entry speeds.
