In 1976 NASA’s Viking 1 took the first photos as a lander on Mars. At the moment Spirit and Opportunity are still working and snapping pictures on Mars.
In 1982 the Soviet Venera 13 lander performed a soft landing on Venus’ surface after many failed missions.
The lander survived for 127 minutes (the planned design life was 32 minutes) in an environment with a temperature of 457 °C (855 °F) and a pressure of 89 Earth atmospheres (8.9 MPa) [Wikipedia]
These achievements are quite impressive considering the technology about three decades ago. I wasn’t even born when those probes landed on our neighbor planets.
