Soviet space program "Venera" for the exploration of Venus.*Launch Date/Time:

*Manufacturer's designation: 2V (V-69)
*Agency: MOM
*Manufacturer:Lavochkin Venera 5 was launched from a Tyazheliy Sputnik (69-001C) towards Venus to obtain atmospheric data. The spacecraft was very similar to Venera 4 although it was of a stronger design.
When the atmosphere of Venus was approached, a capsule weighing 405 kg and containing scientific instruments was jettisoned from the main spacecraft. During satellite descent towards the surface of Venus, a parachute opened to slow the rate of descent. For 53 minutes on
May 16 ,1969 , while the capsule was suspended from the parachute, data from the Venusian atmosphere were returned. It landed at Venus coords and quad cat|3|S|18|E. The spacecraft also carried a medallion bearing the State Coat of Arms of the U.S.S.R. and a bas-relief ofV. I. Lenin to the night side of Venus.Given the results from
Venera 4 , the Venera 5 andVenera 6 landers contained new chemical analysis experiments tuned to provide more precise measurements of the atmosphere's components. Knowing the atmosphere was extremely dense, the parachutes were also made smaller so the capsule would reach its full crush depth before running out of power (as Venera 4 had done).External links
