- 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
