Courtesy of NASA's National Space Science Data Center . Launch Date: 1981-11-04 . Venera 14 landed at 13њ 15 minutes S by 310њ, about 950 kilometers southwest of Venera 13. Surface temperature was 465њC and pressure was 94 Earth atmospheres. Venera 14 carried instruments to take chemical and isotopic measurements, monitored the spectrum of scattered sunlight, and recorded electric discharges during its descent phase through the Venusian atmosphere. ...
