Venera 14 launched 1981



Venera 14, launched November 4, 1981, just 5 days after its identical twin Venera 13, took pictures and audio of Venus.    The descent vehicle separated from the spacecraft and descended into the Venusian atmosphere in March 1982.  A parachute slowed its rate of descent until about 31 miles altitude and then airbraking was used the rest of the way down.  It landed near the eastern flank of Phoebe Regio, about 590 miles southwest of Venera 13.

The lander functioned for at least 57 minutes, although it was planned to last only 32.  It measured the surface temperature of 869° F and 94 Earth atmospheres or 9.5 MPa.
