Pioneer Space Missions
By Neomi Palacios
pioneer 1 was the first spacecraft launched by the newly formed NASA.pioneer 1 was originally designed to land on the moon but it failed to do so because of a valve that was incorrectly set in the upper stage of the probe. The spacecraft ended its transmission when it reentered the Earth's atmosphere after 43 hours of flight on October 13, 1958 over the south pacific ocean and only a small amount of of scientific information was returned .
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 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.
