Kosmos 146 was a Soviet test satellite precursor to the Zond series, launched from the Baikonur Cosmodrome aboard a Proton K rocket.[1] The spacecraft was designed to launch a crew from the Earth to conduct a flyby 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 1967-1970, 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[2][3]


There are differing opinions about the goals and success of the mission "Kosmos-146". Most sources report that Kosmos 146 achieved escape velocity. The goal of Kosmos-146 could not have been to orbit the Moon, since time and place of the launch did not allow for such a trajectory.[4]

The engines of Block D were not started immediately, but only after about eight orbits were completed, which is unusual. Reportedly some speculated that this delay was meant to simulate the arrival of a separately launched crew at the Soyuz spacecraft.[citation needed]

Moon race[edit]

By the time the device was launched, the United States had already thrust into the orbit in their prototype of the lunar vehicle ( AS-201 , AS-202 , AS-203 ). The US could go on to launch manned prototypes of lunar ships before the USSR brought the first unmanned prototype into orbit, but two months before the launch of Kosmos-146, during the fire in the command module, the crew of Apollo 1 was killed.
