Venera 13 Beamed First Venus Color Photos, Analyzed Soil in 127 Minutes

Summary
127 minutes after landing on Venus in March 1982, the Soviet Venera 13 probe transmitted the first color photos from the planet’s surface and completed a soil analysis—far beyond its roughly 30-minute design life.
465C heat and pressure about 92 times Earth sea-level conditions made survival the mission’s central challenge, but a titanium pressure vessel, heavy insulation and pre-chilled electronics kept the lander operating long enough for extra science.
Two color panoramas showed a flat basalt plain near Phoebe Regio, while a drill arm scraped a sample and fed it through an airlock to an X-ray fluorescence instrument that identified basalt-like, potassium-rich material.
The feat capped a decade of Soviet Venus landings that had suffered camera-cap and heat failures, and no later surface mission has surpassed Venera 13’s operating time despite modern advances in high-temperature electronics.

127 Minutes on Venus: The Enduring Legacy of Venera 13 and the Future of Surface Missions
Overview
The Soviet Union's Venera 13 lander set an unmatched record for surviving on Venus, a planet known for its brutally hostile environment. Touching down on March 1, 1982, Venera 13 was built to last only about 30 to 32 minutes, but thanks to its rugged, submarine-like design, it continued sending data for an incredible 127 minutes. This achievement broke the previous record and far outlasted its twin, Venera 14. Even after 40 years, no other mission has survived longer on Venus, making Venera 13 a benchmark for future exploration of this extreme world.
