The Soyuz 7K-L1 was a Soviet spacecraft designed for crewed missions around the Moon. Developed in the 1960s, it was part of the larger Soyuz program and aimed to support lunar exploration. The spacecraft featured a conical shape and was equipped with life support systems to sustain astronauts during their journey. Although the Soyuz 7K-L1 was intended for lunar missions, it never completed a crewed flight. Instead, it underwent several uncrewed test flights, contributing valuable data to the development of future Soyuz spacecraft and the Soviet space program's overall goals.
