Venera 5 was launched into an Earth parking orbit on 5 January 1969 at 06:28:08 UTC and then from a Tyazheliy Sputnik (69-001C) towards Venus. After a mid-course maneuver on 14 March 1969, the probe was released from the bus on 16 May 1969 at a distance of 37,000 km (23,000 mi) from Venus.
Missions to Venus constitute part of the exploration of Venus. The Soviet Union , followed by the United States , have soft landed probes on the surface. Venera 7 was the first lander overall and first for the Soviet Union, touching down on 15 December 1970.
Venera 4 was the first successful probe, and showed that CO 2 is the main component in Venus' atmosphere. [15] [5] Venera 7 found the temperature and pressure data as well as the atmospheric composition. [5] [16] Venera 8 measured the K, U, and Th on the surface through gamma-ray analysis. [5]
The LISA mission includes three spacecraft that will fly 2.5 million kilometers (about 1.6 million miles) apart in a triangle-shaped formation.

During another American flyby in 1967, Mariner 5 measured the strength of Venus's magnetic field. In 1974, Mariner 10 swung by Venus on its way to Mercury and took ultraviolet photographs of the clouds, revealing the extraordinarily high wind speeds in the Venusian atmosphere. Mariner-10 provided the best images of Venus taken so far, the ...
