| Luna-20 landed on the Moon on February 21, 1972. Similar to Luna-16, it was a robotic mission that returned lunar soil to Earth. The spacecraft was equipped with a stereo pair of optical-mechanical cycloramic cameras, which operated at 4 lines per second and 300 pixels per line. Positioned at a 50° angle from vertical, these cameras captured 360° panoramas, showcasing the lunar surface along with parts of the spacecraft and the sky. Additionally, the cameras scanned the drilling site both before and after sampling. |
