American lunar lander
~3 min read
Surveyor 4 is the fourth lunar lander in the American uncrewed Surveyor program sent to explore the surface of the Moon. This spacecraft crashed after an otherwise flawless mission; telemetry contact was lost 2.5 minutes before touchdown. The planned landing target was Sinus Medii (Central Bay) at 0.4° north latitude and 1.33° west longitude.
Surveyor 6 successfully landed near the crash site of Surveyor 4 a few months later in November 1967.
