On 22 March 2025, we used the Dwingeloo telescope to successfully bounce a radio signal off the surface of Venus. At the time, Venus was in its closest approach to Earth at about 42.000.000 km. Such a conjunction happens when Venus is between the Sun and the Earth, and happens approximately every 580 days.
If it exists, a ham will try to bounce radio waves off it, or use it as an antenna.
