Soviet Venera Probes Remain on Venus: Decades of Crushing Heat, Pressure, and Acid

The Soviet Union placed Venera landers on Venus between 1975 and 1982. A 2025 study by Luca Forassiepi finds that at least seven of these probes are still recognizable on the basaltic plains, slowly deformed by roughly 90 bars of pressure and corrosive sulfuric-acid clouds.

The Lavochkin Design Bureau’s Venera program launched dozens of missions from the early 1960s to the mid-1980s. After early failures, Venera 5 and 6 (1969) transmitted atmospheric data to 24 km, Venera 7 (1970) achieved the first confirmed surface transmission, and Venera 9, 10, 13 delivered only colour photographs of another planet’s surface.

Venus’s surface averages about 460 °C (some reports 457 °C) and endures roughly 90 bars (?89 atmospheres) of pressure, with 96 % CO2 and sulfuric-acid droplets that corrode metal within minutes.

The Venera data underpin most models of Venusian surface chemistry, confirming a basaltic crust and a CO2-dominated runaway greenhouse. Venera 13’s colour panoramas remain humanity’s only surface photos of any planet besides Mars, and its acoustic recordings are the first extraterrestrial surface sounds.

Roscosmos reported that the Cosmos 482 descent module re-entered Earth’s atmosphere and impacted the Indian Ocean in 2025. Luca Forassiepi’s 2025 paper notes that the surviving Venera hardware remains recognisable despite deformation. NASA’s DAVINCI mission, slated for launch in the early 2030s, will release a descent probe that could image the Soviet landers. ESA’s EnVision orbiter will map Venus with high-resolution radar.

Commentators note that the Venera program “nobody in the West remembers correctly,” underscoring a cultural gap that obscures the Soviet missions’ scientific importance.

Venera 13 landed east of Phoebe Regio (7.5° S, 303° E) in March 1982, operating for 127 minutes—four times its 32-minute design life—capturing orange-hued basaltic panoramas and basalt-like chemistry.

Sources differ on surface pressure (90 bars vs 89 atmospheres) and temperature (460 °C vs 457 °C). No direct imaging has verified the current state of the landers, leaving their exact deformation uncertain.

Future descent missions such as DAVINCI may capture images of the deformed Soviet landers if landing sites intersect. EnVision’s radar mapping could locate them indirectly. Ongoing material research aims to extend surface operation beyond the current few-hour limit.
