Kosmos 42

 1964-050A


The second Strela-1 launch used the smaller 63S1 rocket from the Kapustin Yar site, and carried only two satellites, which were named Kosmos-42 and Kosmos-43. The launch came only four days after the initial 65S3 launch, and the reason for it is obscure. It is possible that the pair were intended to test out the separation mechanism and were originally planned to fly first, or were planned as a backup in case there were problems with the test launch of the heavier 65S3 launch vehicle.
