Kosmos 146 (Russian: Космос 146, lit. 'Cosmos 146'), also known as Soyuz 7K-L1 No. 2P, was a Soviet test spacecraft precursor to the Zond series, launched from the Baikonur Cosmodrome aboard the inaugural flight of the Proton-K rocket, an improved version of the Proton, which had been launched four times before.^[3]

The spacecraft was designed to launch a crew from the Earth to conduct a flyby of the Moon and return to Earth. The primary focus was a Soviet circumlunar flight, which help document the Moon, and also show Soviet power. The test ran from the Zond program from 1967 to 1970, which produced multiple failures in the 7K-L1's re-entry systems. The remaining 7K-L1s were scrapped, ultimately replaced by the Soyuz 7K-L3.^[4]

Objectives

Kosmos 146 was a Soviet test precursor to the Zond series, launched from the Baikonur cosmodrome aboard a Proton K rocket. It was launched into a planned highly elliptical Earth orbit. The Blok D stage functioned correctly in putting the spacecraft into a translunar trajectory. It was not aimed at the Moon and no recovery of the spacecraft was planned or attempted. It was a successful mission that created false confidence just before a string of failures that would follow.^[1]

Kosmos 146 was launched using a Proton-K carrier rocket, which flew from Site 81/23 at Baikonur. The launch occurred at 11:30:33 GMT on 10 March 1967 and was successful. Kosmos 146 was operated in an Earth orbit, it had a perigee of 177 kilometres (110 mi), an apogee of 296 kilometres (184 mi), an inclination of 51.5° and an orbital period of 89.2 minutes. Kosmos 146 decayed from orbit on 18 March 1967.^[2]

Moon race

By the time the spacecraft was launched, the United States had already deployed prototypes of their lunar vehicle (AS-201, AS-202, AS-203) in low earth orbit. The United States flight tests came to a halt when the crew of Apollo 1 was killed by a fire in the command module two months before the launch of Kosmos 146.
