Venera 14 was identical to its twin, Venera 13.
The spacecraft carried out three midcourse corrections on the way to Venus: on 14 November 1981, 23 November 1981, and 25 February 1982. Russian sources indicate that one of the corrections was incorrect (probably the first) and could have jeopardized the mission.
The lander probe separated from its flyby parent on 3 March 1982 before the entry cycle began. The probe's main parachute opened at an altitude of 62 to 63 kilometers, thus activating the atmospheric instruments. The parachute was released at an altitude of 47 kilometers, and the 760-kilogram lander fell to the surface using only the atmosphere as a retarding medium.
The probe made safe contact with the Venusian surface at 07:00:10 UT on 3 March 1982 and continued with 57 minutes of transmissions. Landing coordinates were 13.25° south latitude and 310° longitude, about 1,000 kilometers from the Venera 13 landing site.
As with its twin, Venera 14 returned color photographs of its surroundings and examined a soil sample (about 1 cubic centimeter taken from a 30-millimeter-deep sample). Soil was deposited in a chamber sealed off from the outside environment and was then progressively transferred through a series of chambers by blowing air until the sample was deposited in its final chamber with a temperature of only 30°C. Here it was examined by the x-ray fluorescence spectrometer.
Temperature and pressure outside were considerably higher than at the Venera 13 site: 470°C and 93.5 atmospheres, respectively.
The flyby probe, meanwhile, passed Venus at a range of 36,000 kilometers and entered heliocentric orbit, continuing to provide data on solar x-ray flares. It performed one trajectory change on 14 November 1982.
