mission

Surveyor 4 was launched on 14 July 1967 aboard an Atlas - Centaur rocket from the launch pad LC-36 of the Cape Canaveral Air Force Station . After an uneventful flight, the probe reached the moon on July 17, 1967. About 3 minutes before the planned touchdown on the lunar surface, the radio signals broke off. Further efforts to get in touch failed. It is believed that the probe exploded on approach due to a malfunction.
