| .....Venera
4 was launched from a Tyazheliy Sputnik (67-058B)
towards the planet Venus with the
announced mission of direct atmospheric
studies. On October 18, 1967, the
spacecraft entered the Venusian
atmosphere and released two thermometers,
a barometer, a radio altimeter, and
atmospheric density gauge, 11 gas
analyzers, and two radio transmitters
operating in the DM waveband. The main
bus, which had carried the capsule to
Venus, carried a magnetometer, cosmic ray
detectors, hydrogen and oxygen
indicators, and charged particle traps.
Signals were returned by the spacecraft,
which braked and then deployed a
parachute system after entering the
Venusian atmosphere, until it reached an
altitude of 24.96 km. |
