Venera 7 survived a landing on Venus

The 1970 probe sent data from the surface for about 23 minutes Venera 7 entered the Venusian atmosphere in December 1970 and reached the ground, becoming the first spacecraft to transmit from another planet's surface. Its parachute partly failed and it hit hard, yet the probe lasted around 23 minutes at roughly 475 degrees Celsius. It measured wind speeds near the surface far lower than expected. It sits in Mondo's space collection, one of 200 facts that each trace back to the reference below.
