Kosmos 146(Russian:Космос 146meaningCosmos 146), also known asL-1 No. 2P,was a Soviet test spacecraft precursor to theZondseries, launched from theBaikonur Cosmodromeaboard aProton Krocket.[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 Sovietcircumlunarflight, 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 the7K-L1's re-entry systems. The remaining 7K-L1s were scrapped, ultimately replaced by theSoyuz 7K-L3.[4]
Objectives
[edit]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 plannedhighly elliptical Earth orbit.TheBlok Dstage 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 aProton-Kcarrier rocket, which flew fromSite 81/23atBaikonur.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 146decayedfrom orbit on 18 March 1967.[2]
Moon race
[edit]By the time the spacecraft was launched, the United States had already deployed prototypes of their lunar vehicle (AS-201,AS-202,AS-203) inlow earth orbit.The United States flight tests came to a halt when the crew ofApollo 1was killed by a fire in thecommand moduletwo months before the launch of Kosmos 146.
