Sputnik II has not yet split into two parts, according to Dr. J. Allen Hynek, Associate Director of the Smithsonian Astrophysical Institute.
In a press conference yesterday, Hynek stated that there was not sufficient evidence to assume that the satellite had split, since only one report out of thousands observed such a break.
When asked by one reporter whether any end-over-end tumbling of the satellite would have any effect on the dog inside, Hynek replied, "Never having been a dog in a rocket, I don't know."
Sputnik II will pass over Boston at 12:56 Saturday afternoon. Hynek said, however, that football spectators should not attempt to spot the rocket with the naked eye, but that the Institute will try with a five-inch telescope.
