Venera 14 ( _ru. Венера-14) was a probe in the Soviet Venera program for the exploration of Venus.

Venera 14 was identical to the Venera 13 spacecraft and built to take advantage of the 1981 Venus launch opportunity and launched 5 days apart. It was launched on 1981-11-04 at 05:31:00 UTC and Venera 13 on 1981-10-30 at 06:04:00 UTC, both with an on-orbit dry mass of 760 kg.


Each mission consisted of a bus and an attached descent craft.

As it flew by Venus the bus acted as a data relay for the lander and then continued on into a heliocentric orbit. It was equipped with a gamma-ray spectrometer, UV grating monochromator, electron and proton spectrometers, gamma-ray burst detectors, solar wind plasma detectors, and two-frequency transmitters which made measurements before, during, and after the Venus flyby.

The descent lander was a hermetically sealed pressure vessel, which contained most of the instrumentation and electronics, mounted on a ring-shaped landing platform and topped by an antenna. The design was similar to the earlier Venera 9–12 landers. It carried instruments to take chemical and isotopic measurements, monitor the spectrum of scattered sunlight, and record electric discharges during its descent phase through the Venusian atmosphere. The spacecraft utilized a camera system, an X-ray fluorescence spectrometer, a screw drill and surface sampler, a dynamic penetrometer, and a seismometer to conduct investigations on the surface.

* Radio / Microphone / Seismometer - Groza-2
* Nephelometer - MNV-78-2
* Hydrometer - VM-3R
* X-Ray Fluorescence Spectrometer (Aerosol) - Bora-1
* X-Ray Fluorescence Spectrometer (Soil) - Arakhis-2
* Soil Drilling Apparatus - GZU
* Stabilized Oscillator / Doppler Radio

After launch and a four month cruise to Venus the descent vehicle separated from the bus and plunged into the Venusian atmosphere on March 5, 1982. After entering the atmosphere a parachute was deployed. At an altitude of about 50 km the parachute was released and simple airbraking was used the rest of the way to the surface.

Venera 14 landed at Venus coords and quad cat|13.25|S|310|E (about 950 km southwest of Venera 13) near the eastern flank of Phoebe Regio on a basaltic plain.

The lander had cameras to take pictures of the ground and spring-loaded arms to measure the compressibility of the soil. The quartz camera windows were covered by lens caps which popped off after descent. Venera 14, however, ended up measuring the compressibility of the lens cap, which landed right where the probe was to measure the soil. [ [ Dr Karl - Murphy's Law, Part two ] ] [Images available at]

The composition of the surface samples was determined by the X-ray fluorescence spectrometer, showing it to be similar to oceanic tholeiitic basalts.

The lander survived for 57 minutes (the planned design life was 32 minutes) in an environment with a temperature of 465 °C and a pressure of 94 Earth atmospheres (9.5 MPa).
