Pioneer 4
1959-013A
The second JPL/ABMA probe, Pioneer IV, again nominally a NASA launch, was launched by Juno II at 0510:56 on 1959 Mar 3. The Jupiter cut off at 0512 and separated 5s later. The Jupiter guidance section remained attached to the Cluster (JPL Cluster 12). Next the nose fairing was separated, and then the Stage 2 fired, separating from the Cluster rotational launcher fixed to the Jupiter guidance section. The remaining stages fired in quick succession, and separated from the payload. The payload was then despun from 416 revs per min to 11 rpm using release masses on wires. Low performance resulted in missing the Moon, but achieving solar orbit. At 2224 on Mar 4 Pioneer IV passed the Moon at a distance of 60600 km and sailed on into solar orbit.
The final stage (motor serial TC-25) and the despin weights also entered solar orbit. It stopped transmitting after 82h, at around 1500 on Mar 6, at a range of 669000 km. It reached perihelion on Mar 17 and aphelion on Oct 1.

Kosmos 581
1973-059A
Kosmos-581 was launched in Aug 1973, while the previous Zenit-4M mission was in orbit. The launch was from Baikonur into a 51.6 degree orbit. A TK recovery beacon was detected.
