Description
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. The spacecraft also carried
a medallion bearing the coat of arms of the U.S.S.R. and a bas-relief of
V.I. Lenin to the night side of Venus.
