First Spacecraft to Land on Venus Surfaces

March 1st, 1966 59 years ago

Venera 3, a Soviet space probe, became the first human-made object to impact the surface of another planet when it crashed into Venus. Launched on November 16, 1965, it was designed to transmit data back to Earth about Venus's atmosphere and conditions. However, due to technical difficulties, the probe was only able to send back limited information before its abrupt landing. Regardless, this mission marked a milestone in planetary exploration.
