Mariner 5

Part of the Mariner program

Mariner 5 picture Mariner 5 carried a complement of experiments to probe Venus's atmosphere with radio waves, scan its brightness in ultraviolet light, and sample the solar particles and magnetic field fluctuations above the planet. It flew by Venus on October 19, 1967 at an altitude of 3,990 kilometers. With more sensitive instruments than its predecessor Mariner 2, Mariner 5 was able to shed new light on the hot, cloud-covered planet and on conditions in interplanetary space. Operations of Mariner 5 ended in November 1967.

Octagonal bus structure with four solar panels. 3-axis stabilized using cold gas thrusters. S-Band communications via LGA and HGA. Thermal shield.

Instruments examined Venus' atmosphere with radio waves and ultraviolet scanners and sampled the solar particles and magnetic fields in the region of the planet.
