the r-7 was also known by its gurvo designation 8k71, as well as the t-3, m-104, and type a. the r-7 modified for the ps-2 satellite launch was designated 8k71ps. unlike sputnik 1, sputnik 2 was not designed to detach from the r-7 sustainer core, since sputnik 1's core stage had demonstrated an acceptable orbital lifespan. this allowed the core's tral d telemetry system to be used to transmit data, but would lead to speculation that sputnik 2 had failed to separate. after sputnik 2 reached orbit, the interior temperature rapidly climbed to over 40 °c (100 °f), and laika survived for only a few hours instead of the planned ten days.
