Proofs of life on Venus

Discovering chemical substances as possible chemical markers of life existence in Venus’s atmosphere via remote astronomical observations cannot be considered objective evidence of life existence on the planet, says Roscosmos Executive Director for Science and Advanced Programs Alexander Bloshenko. ‘Credible scientific data on that matter can be obtained only via tangent explorations of the planet’s surface and atmosphere,’ he added.

Notably, the USSR was the only country to conduct regular explorations of Venus using on-planet stations. The first ever soft landing on another planet’s surface in the Solar system was performed in 1970 by the Venera-7 descent module. Several orbital missions and landings provided detailed data on the Venerian climate, soil and atmosphere composition. The USSR’s Venera-13 spacecraft still holds the record as the longest active spacecraft on Venus remaining operational for 127 minutes.

A huge breakaway of the Soviet Union from its competitors in exploration of Venus contributed to the fact that USA called Venus a ‘Soviet planet’. Having recently analyzed the pictures of Venus captured by Soviet missions, scientists of the Russian Academy of Sciences claimed they discovered moving objects that even might be living. It is yet to be seen, whether these guesses are true.

Today, a program of complex exploration of Venus has been developed by Russia’s Roscosmos space agency in cooperation with the Russian Academy of Sciences. The program consists of several missions. Moreover, a decision was taken to implement the previously planned Venera-D mission including orbital and landing modules, as a national project without involving wide international cooperation. The complex explorations will also include soil and atmosphere samples, as well as exploring evolution processes on Venus that has purportedly suffered a climatic disaster due to greenhouse effect that is much discussed on Earth today.
