♟️The First Soft Landing on Venus 🍎

The name of the spacecraft that made the first soft landing on Venus was Venera 7. It was launched by the Soviet Union on August 17, 1970, and successfully landed on the surface of Venus on December 15, 1970. Venera 7 was the first spacecraft to transmit data from the surface of another planet, and it provided valuable information about the harsh conditions on Venus, including the extremely high temperatures and atmospheric pressure. The success of Venera 7 paved the way for further exploration of Venus by the Soviet Union and other countries.
