Launch of first Cosmos satellite on Mar 16 1962, marked major change in Soviet official information policy; previously weight of all space payloads has been announced, although certain details, such as spacecraft dimensions and size and weight of final stage rocket bodies, were kept secret; for Cosmos series, not even payload weights have been divulged; paper attempts to deduce probable size and weight of 49° orbit Cosmos craft, based on direct observations of certain Cosmos satellites.
