The Soviets have been particularly prolific in sending probes to Venus.
They have successfully landed 8 spacecraft on the surface of Venus, with
each spacecraft lasted at least 53 minutes before succumbing to the
heat and pressure of the Venusian environment.  Venera 13 holds the record
of 127 minutes on the surface.  The Soviets have also
sent two balloons to Venus in 1985 that survived nearly two days in
the upper atmosphere of the planet.  The U.S. have never sent a true lander
to Venus, but two of the Pioneer Venus probes, which impacted on Venus in 1978,
actually survived the impact and continued to trasmit from the surface.  Below
is a table of how long each spacecraft lasted on the surface of Venus.

   1975    Venera 9              53 minutes
   1975    Venera 10             65 minutes
   1978    Pioneer Venus probe   2 seconds
   1978    Pioneer Venus probe   67.5 minutes
   1978    Venera 11             95 minutes
   1978    Venera 12             110 minutes
   1982    Venera 13             127 minutes
   1982    Venera 14             57 minutes
   1985    Vega 1                56 minutes
   1985    Vega 2                57 minutes
