Luna 9

Luna 9 (Луна-9), internal designation Ye-6 No.13, was an uncrewed space mission of the Soviet Union’s Luna programme. On 3 February 1966, the Luna 9 spacecraft became the first spacecraft to achieve a survivable landing on a celestial body.

The lander had a mass of 99 kilograms (218 lb) and consisted of a spheroid ALS capsule measuring 58 centimetres (23 in). It used a landing bag to survive the impact speed of 22 kilometres per hour (14 mph). It was a hermetically sealed container with radio equipment, a program timing device, heat control systems, scientific apparatus, power sources, and a television system.
