pioneer 1
pioneer 2
pioneer 2 was made to orbit all the moon pioneer 2 was nearly identical to pioneer 1 and consisted of almost the same material. and then shortly after the launch, the third stage of the launch vehicle separated but failed to ignite.pioneer failed to orbit the moon a very small amount of information was collected.
pioneer 3
pioneer 4
After a successful launch Pioneer 4 succeeded its primary objective which was an an earth moon trajectory The probe was tracked for 82 hours to a distance of 655,000 km and reached perihelion on 18 March 1959
pioneer 5
pioneer 5 was used to investigate interplanetary space between the orbits of earth and Venus.The major portion of the data was received at the Manchester and Hawaii tracking stations because their antennas had better signal and were able to retrieve all the data clearly.The spacecraft established a communications link with the earth from a record distance of 22.5 million miles on June 26, 1960, which was the last day of data transmission.

pioneer 8
pioneer 9
pioneer 9 was used to study cosmic rays magnetic fields cosmic dust and electric fields.they kept track of the probe until may 1983. NASA made an unsuccessful attempt in 1987 to contact the probe and then the mission was declared inactive at that time
